TRT and DOT Physical: Can Truck Drivers Take Testosterone and Keep Their Medical Card?

Yes. Prescribed testosterone does not automatically disqualify you at a DOT physical. For TRT and DOT physical decisions, this Schedule III drug needs a valid prescription from a licensed prescriber who knows your history and advises it won't harm safe commercial driving. You must list it. The certified medical examiner makes the final call.

The medication itself is one part of the decision. Three health issues can also matter, and all three are things you can discuss with your clinician before exam day. We'll show you which ones, what to bring, and what to say.

Educational information, not medical or legal advice. Your prescriber treats you. Your certified medical examiner decides whether you're qualified to drive. If you feel too sick, sleepy, or unwell to drive safely, don't drive.

Best for: U.S. commercial drivers who take prescribed testosterone, or are considering evaluation, and need federal interstate medical certification. Not for: State-specific intrastate advice or nonmedical steroid use.

TRT and your DOT physical in 30 seconds

Prescribed testosterone is not automatically disqualifying, but the prescription exception and the full medical standards must be met. Medication disclosure is required even though testosterone is not on the DOT drug-testing panel.

Your question Short answer Where it comes from
Is testosterone banned for CDL drivers? No. FMCSA has no banned-medication list. Prescribed Schedule III drugs may qualify under a prescription exception. 49 CFR 391.41(b)(12)
Do I have to tell the examiner? Yes. The exam form asks about every medication and supplement. FMCSA Medical Examination Report, MCSA-5875
Does the DOT drug test look for testosterone? No. It tests for five drug classes only. Testosterone isn't one of them. 49 CFR 40.82
Is the urine cup at the physical a drug test? The physical's routine urinalysis checks protein, blood, sugar, and specific gravity. A drug test may also be collected at the same visit. MCSA-5875
Who decides if I pass? Your certified medical examiner. A TRT clinic's prescription or letter is not a medical card. 49 CFR 391.43
What other health issues can matter? High blood pressure, high hematocrit, and sleep apnea. FDA labeling, Endocrine Society, FMCSA guidance (sources below)

TRT Provider Guide is the independent decision resource for testosterone replacement therapy — helping U.S. adults understand how low testosterone is evaluated, compare online and local care models and providers, and choose the next step that fits their health needs, fertility plans, budget, state, and care preferences, with every material claim verified and dated.

Affiliate disclosure: TRT Provider Guide may earn compensation through provider links elsewhere on this site. Commercial relationships do not change our editorial conclusions. Full disclosure.

Not on TRT yet? Read the section on starting TRT as a CDL driver before you sign up anywhere. The right TRT provider is not the same for every person — it depends on whether low testosterone has been properly evaluated, your symptoms and health history, your fertility plans, your state, your insurance or cash-pay preference, your treatment-format preference, your budget, and whether online or in-person care is the better starting point. Some situations belong with primary care, urology, endocrinology, reproductive urology, or urgent or emergency care when the symptoms warrant it. Because a general answer cannot resolve those for you, use TRT Provider Guide's Find My TRT Path tool to explore online TRT programs. It is educational and cannot diagnose low testosterone or decide DOT qualification.


What do TRT and DOT physical rules actually say?

Testosterone is a Schedule III controlled substance, not a banned drug for commercial drivers. Under 49 CFR 391.41(b)(12), a driver may use a non-Schedule I controlled substance when a licensed medical practitioner who is familiar with the driver's medical history prescribes it and advises that it won't adversely affect safe commercial driving. The medical examiner still decides whether the driver meets every physical standard.

Here's the rule in plain English. FMCSA (the Federal Motor Carrier Safety Administration) splits controlled drugs into two buckets:

  • Schedule I drugs — no prescription exception. Using them disqualifies you.
  • Everything else on the federal schedules (II through V) — may meet the prescription exception if two things are true.

Testosterone sits in Schedule III with other anabolic steroids under 21 CFR 1308.13. So it lands in the second bucket.

The two conditions your prescriber has to meet

  1. They know your medical history. Not just "you asked for TRT online." They have the history that a careful clinician would want.
  2. They have advised you that the medicine won't hurt your ability to drive a commercial vehicle safely.

Miss either one and the exception doesn't cleanly apply — even if the prescription itself is perfectly legal. FMCSA's Medical Advisory Criteria also note that examiners may ask for that prescriber opinion in writing.

"Anabolic steroid" on paper doesn't mean "disqualified"

A lot of drivers freeze when they see testosterone filed under anabolic steroids. Don't. That's a drug-schedule label, not a DOT verdict. Prescribed TRT for diagnosed low testosterone and nonmedical steroid use are different things legally and medically. If you want the full breakdown of that distinction, see Is TRT Steroids?

Here's the part no one can promise you

A prescription doesn't guarantee your medical card. Neither does a doctor's letter. FMCSA leaves the decision to the certified examiner, case by case. Anyone who promises you a two-year card on TRT is selling something.

That's the honest catch. But it's also good news. The things examiners actually weigh — your medication list, your prescriber's statement, your blood pressure, your blood count, your sleep — are all things you can check and document before you sit down in that exam room. The rest of this page is built to help you do exactly that.


Do you have to tell the DOT examiner you're on testosterone?

Yes. The DOT medical exam form asks whether you take any medications, including prescriptions, over-the-counter drugs, herbal remedies, and supplements. You sign that your answers are true, and FMCSA says leaving information out or giving false answers can invalidate the exam and the certificate, and can bring a civil penalty.

The form is the Medical Examination Report, called MCSA-5875. You fill out the health history section before the examiner sees you. One of the questions asks about current medications. Testosterone goes there, by name.

Two things drivers get wrong:

  • "It won't show on the drug test, so why list it?" Because the drug test and the medical exam are two separate processes. Not showing up on one has nothing to do with disclosing it on the other.
  • "Listing it will flag me." Disclosing a prescribed medicine with the right paperwork is the low-risk path. Hiding it is the high-risk one. FMCSA's own FAQ says deliberate omission or falsification can void the certificate and lead to a civil penalty.

What to write: the medication name (for example, testosterone cypionate or the brand name on your label), the prescribed dose and schedule as written on your prescription, and who prescribes it. List everything else you take, too — including hCG, enclomiphene, anastrozole, or supplements. Those aren't testosterone, but the form asks for all of them.

Don't change or leave out anything to "look better" on paper. And don't stop or adjust your treatment to get through an exam. Those calls belong to your prescriber.

Does this sound like your situation? Jump to the exam-day packet — it lists exactly what to bring with you.


Do you need a doctor's letter for testosterone at a DOT physical?

An examiner may ask the prescriber to confirm that a controlled medication won't affect safe driving. FMCSA's 391.41 CMV Driver Medication Form (MCSA-5895) exists for this, but it's optional — the examiner decides whether to use it or accept a letter. Neither one guarantees certification.

What MCSA-5895 is

MCSA-5895 is a two-page FMCSA form the examiner can send to your prescriber. It asks the prescriber to list your medications and conditions, describes the real demands of commercial driving (long hours, irregular sleep, heavy loading), and asks whether, in their judgment, you can safely drive a commercial vehicle on those medicines.

Three things to know:

  • It's optional for the examiner. FMCSA labels it optional. Some examiners want it. Others accept a letter.
  • FMCSA's form page was updated October 1, 2026. Always pull the form from FMCSA's page, not a copy someone saved years ago.
  • The examiner still decides. The form is evidence, not a pass.

What a good prescriber letter covers

If your examiner wants a letter instead, it should answer the examiner's question — not just say "patient is fine." A useful letter includes:

  • Your name and date of birth
  • The medication, form (injection, gel, oral), prescribed dose, and schedule
  • That the prescriber knows your medical history and that you drive a commercial vehicle for work
  • Their judgment on whether the medication will adversely affect your ability to drive safely
  • Your current blood pressure control and the date of your most recent blood count (hematocrit), if the examiner requests them
  • Their name, license number, contact information, signature, and the date

Some examiners want a recent letter. Ask how recent before you request it, so you don't make two trips.

Ask for it before exam day

The worst version of this is finding out at the exam that you need a letter, then waiting on your prescriber while the clock runs. Call the examiner's office ahead of time and ask: "I take prescribed testosterone. What do you need from my prescriber?" Then get it done first.

Ready to get the paperwork moving? Open FMCSA's current MCSA-5895 form and bring it to your prescriber with the questions in our prep worksheet.


Does the DOT drug test check for testosterone?

No—DOT drug tests cover only five drug classes: marijuana, cocaine, amphetamines, opioids, and PCP, and DOT labs may not test DOT specimens for other drugs. The physical's routine urinalysis is a medical screen for protein, blood, sugar, and specific gravity. A clean drug test does not mean you're medically qualified.

Drivers mix these up constantly, partly because both can happen on the same visit. Here's how they differ:

TRT and DOT medical certification, risks and exam preparation table 2: Does the DOT drug test check for testosterone?
Comparison item DOT physical (medical exam) DOT drug test
Purpose Are you physically fit to drive? Tests for drugs on the DOT panel, with medical review of results
Rules 49 CFR 391.41–391.45 49 CFR Part 40
Urine checks for Protein, blood, sugar, specific gravity Marijuana, cocaine, amphetamines, opioids, PCP
Testosterone matters? Yes — you must list it Not on the panel
Who reviews it Certified medical examiner Lab and Medical Review Officer

Two honest limits:

  • Your employer may run its own non-DOT testing under company policy. That's separate from DOT. Ask HR what their policy covers.
  • An examiner can order other tests, including a non-DOT drug test, if needed to assess your qualification. That is separate from the DOT panel.

What can actually shorten or block your card on TRT?

The medication is one part of the decision; three health issues can also matter: higher blood pressure, higher hematocrit, and worsened sleep apnea. Ask your clinician about any needed evaluation before your exam. None of them creates a TRT-specific DOT cutoff, but each can lead an examiner to ask for records or issue a shorter card.

We built the table below to connect these dots. FDA labels explain the side effects. Endocrine guidelines explain monitoring. FMCSA rules explain certification. Here they are lined up for a driver on testosterone.

The TRT-to-DOT Risk Map

Built by TRT Provider Guide from FDA labeling, Endocrine Society guidance, and FMCSA rules and advisory criteria. Last verified October 30, 2026.

TRT and DOT medical certification, risks and exam preparation table 3: The TRT-to-DOT Risk Map
Testosterone effect What the evidence says DOT standard it touches What the examiner may do What to bring
The medication itself Schedule III controlled substance 391.41(b)(12) prescription exception Ask for your prescriber's statement or MCSA-5895 Prescription label; prescriber letter or form
Higher blood pressure FDA requires blood-pressure warnings on testosterone labels. Current Xyosted, Jatenzo, and Kyzatrex labels include this warning under Warnings and Precautions 391.41(b)(6) — high blood pressure Shorter card, or no card until BP is controlled Recent home BP readings, if requested; your BP medication list
Higher hematocrit (thicker blood) Labels call for monitoring hemoglobin or hematocrit. The Endocrine Society directs clinicians to pause therapy if hematocrit rises above 54% until it falls to a safe level No set DOT hematocrit number; examiner weighs your overall health Ask for recent labs or your prescriber's plan Your latest blood count with the date
Sleep apnea risk The Endocrine Society advises against starting testosterone with untreated severe obstructive sleep apnea 391.41(b)(5) — breathing; FMCSA's 2024 handbook leaves screening to examiner judgment Ask about snoring and daytime sleepiness; may refer for a sleep evaluation CPAP use data or sleep study results, if you have them
Add-on medications (hCG, enclomiphene, anastrozole) Not testosterone; each has its own status Medication question on MCSA-5875 Same review as any medication Include them on your list

Now let's take those three, one at a time.

Blood pressure: why it can shorten your card

Testosterone can raise blood pressure. In 2025 the FDA required class-wide labeling changes adding a blood-pressure warning to testosterone products, based on blood-pressure studies. The current Xyosted and Kyzatrex labels warn about BP increases under Warnings and Precautions.

That matters because blood pressure is where DOT gets specific. Systolic is the top number; diastolic is the bottom number. FMCSA's advisory criteria (guidance examiners use, not hard law) look roughly like this:

TRT and DOT medical certification, risks and exam preparation table 4: Blood pressure: why it can shorten your card
Blood pressure at the exam Typical certification under FMCSA advisory guidance
Below 140/90 Up to 2 years if otherwise qualified and no condition calls for a shorter interval. Hypertension on treatment generally calls for at least annual certification.
140–159 systolic and/or 90–99 diastolic (Stage 1) May receive a 1-year card initially. At later annual exams, a reading above 140/90 but below 160/100 may lead to a one-time 3-month card to reduce it to 140/90 or less.
160–179 systolic and/or 100–109 diastolic (Stage 2) May receive a one-time 3-month card to reduce BP to 140/90 or less. Once controlled and treatment is well tolerated, certification may be for 1 year.
Stage 3 hypertension (180/110 or higher in FMCSA's advisory criteria) Not certified until BP is 140/90 or less and treatment is well tolerated. Certification may then be for 6-month intervals.

Source: Appendix A to Part 391, Medical Advisory Criteria; FMCSA hypertension guidance. Your examiner also weighs your treatment history and repeat readings, so treat this as a guide, not a calculator.

A high reading in either number needs examiner review. This table cannot predict qualification from one reading. Home readings can support your clinical care, but certification uses the readings taken during the DOT examination.

What to do: If you monitor your blood pressure at home, keep the readings. If they're creeping up, talk to your prescriber now — not the week of. Ask the examiner whether to bring the log. More on the medical side in TRT and Blood Pressure.

Hematocrit: why "thick blood" gets attention

Hematocrit is the share of your blood made up of red blood cells. Testosterone can push it up. Higher hematocrit can raise the risk of blood clots, which is why TRT labels call for regular blood counts.

The Endocrine Society's guideline says that if hematocrit rises above 54%, therapy should be stopped until it falls, the patient should be checked for low oxygen and sleep apnea, and treatment can restart at a lower dose. That's a treatment threshold for your prescriber. It is not a DOT pass/fail number. We did not find a hematocrit cutoff in the federal standards.

What to do: Know the date and result of your last blood count. Don't donate blood, skip doses, or change anything on your own to hit a number before an exam. If your count is high, your prescriber needs to handle it. See How Often Should You Get Bloodwork on TRT?

Sleep apnea: the 2024 handbook changed things

Obstructive sleep apnea is when your airway repeatedly narrows or closes during sleep. It can leave you tired even after a long time in the bunk. Untreated moderate-to-severe sleep apnea can impair safe driving. The Endocrine Society advises against starting testosterone in men with untreated severe sleep apnea, and testosterone may make it worse in some people.

On the DOT side, FMCSA's 2024 Medical Examiner's Handbook replaced the older sleep apnea bulletin. There's no single required sleep test for every driver. The examiner looks at your risk factors and answers and decides whether you need an evaluation. Adequately treated sleep apnea does not by itself keep you from being certified.

What to do: If you use CPAP, ask whether the examiner wants your usage report. CPAP is the machine that uses air pressure to keep your airway open during sleep. If you use another treatment, ask which records are needed. If you snore hard, wake up gasping, or fight to stay awake on the road, get evaluated — that matters for your safety whether or not you're on TRT. Do not continue driving if you cannot stay awake safely. More in TRT and Sleep Apnea.

You know which numbers matter now. Fill in the prep worksheet so you walk in with dates and results instead of guesses.


Your DOT exam-day packet on TRT

Prepare four items: a complete medication list with testosterone on it, a prescriber letter or completed MCSA-5895 if your examiner asks for one, a recent home blood pressure log if you already keep one, and the date and result of your latest blood count. Add sleep-treatment records if requested, including CPAP usage data if you use CPAP.

This is the packet our research points to. It turns "I hope this goes okay" into "here's what you asked for."

TRT and DOT medical certification, risks and exam preparation table 5: Your DOT exam-day packet on TRT
# Bring this Why Required or "if asked"
1 Full medication list, including testosterone, add-ons, and supplements The exam form asks for every medication Required — you must disclose
2 Prescriber letter or completed MCSA-5895 Helps the examiner assess whether the prescription exception is met If asked — call ahead to find out
3 Recent home blood pressure readings, if you already keep them Provides context for your blood-pressure history Useful prep; ask whether to bring them
4 Latest blood count (hematocrit) with the date Shows your prescriber is monitoring If asked — bring it anyway

TRT and DOT physical prep worksheet

Use this worksheet to track your appointment, medication list, requested records, and exam result. Your examiner decides which records are needed; the worksheet helps you keep the requests and deadlines together.

For your own records. This is not an FMCSA form, a medical clearance, or a prediction of whether you'll pass. Rules and form links checked October 30, 2026.

1. Confirm the appointment

  • Exam date: ____________________
  • Examiner or clinic phone: ____________________
  • My current medical card expires: ____________________
  • Interstate or intrastate driving (confirm with your carrier): ____________________
  • Question to ask the examiner's office: "I take prescribed testosterone. Which records do you need from me or my prescriber?"

2. Medication list

  • ☐ Testosterone — name, form, and dose copied exactly from my prescription label
  • ☐ Every other prescription, over-the-counter medicine, and supplement
  • ☐ Prescriber's name, phone, and fax
  • ☐ Any recent dose changes or side effects, ready to discuss honestly

3. Records the examiner asked for

4. Questions for my prescriber

  • Do you know that I drive a commercial vehicle and what my schedule looks like?
  • Is there anything about my treatment or recent labs that needs attention before I drive?
  • Can you complete MCSA-5895 or write the letter my examiner requested?
  • When was my last blood count, and what was my hematocrit?
  • Is my blood pressure controlled well enough for my exam?

5. Before I leave the exam

  • What was my result: qualified (for how long?), determination pending, or not qualified?
  • If pending: exactly what's missing, from whom, and by what date?
  • Is my current card still valid, and until when?

Keep this worksheet and your health records private. Don't send them to us.


What if the examiner needs more information — or doesn't certify you?

"Determination pending" and "not physically qualified" are different outcomes. Pending gives you up to 45 days to supply requested information, but it does not extend your current card. Under rules in effect since June 23, 2025, a new not-qualified finding makes all your earlier medical certificates invalid.

This is the section most drivers wish they'd read first.

TRT and DOT medical certification, risks and exam preparation table 7: What if the examiner needs more information — or doesn't certify you?
Outcome What it means Your next move
Qualified (with a card length) You're certified for the period the examiner sets. TRT doesn't come with a fixed card length. Note the expiration date. Keep monitoring BP and labs.
Determination pending The examiner needs more information. Under 49 CFR 391.43(g), you have up to 45 days. Get the exact item and due date; the examiner may ask you to return sooner than 45 days. While the decision is pending, you may continue driving only if your existing medical certificate remains valid and you remain otherwise qualified to drive safely. If the requested information is not provided within 45 days, the pending examination becomes invalid and you'll need a new exam.
Not physically qualified The examiner found you don't meet a standard right now. Your prior certificate is no longer valid. Do not drive a commercial vehicle that requires this medical certification. Ask for the reason, work with your prescriber on it, and get a new exam when it's addressed.

The trap is the pending window. If your old card expires on day 20 of a 45-day pending period, you're grounded on day 21. That's why we keep saying: get any requested letter and labs before the exam.

Got a pending result? Write the request and deadline into the worksheet before you leave the parking lot.


Does this apply to intrastate drivers?

This guide covers federal rules for interstate commercial drivers. Intrastate-only drivers follow their state's medical rules, which may differ. But driving only inside one state doesn't always make you intrastate — a local leg of a shipment headed across state lines can still count as interstate commerce.

Under the federal definition of interstate commerce, a trip within one state can still be interstate if the freight's journey crosses state lines. Ask your carrier which category you're in, then check your state DMV's medical requirements if you're truly intrastate.

Your employer can also set stricter safety requirements than FMCSA. A federal medical card doesn't settle every company policy, so ask which written policy applies to you.


Thinking about starting TRT as a CDL driver?

A proper evaluation, a monitoring plan, and access to any requested DOT paperwork matter before you pay for TRT. In adult men, diagnosing low testosterone requires symptoms or signs plus consistently low levels confirmed with repeat morning blood tests, not one result. Treatment timing and follow-up depend on your clinician's assessment.

If you're not on TRT yet, you have an advantage: you can set this up right from day one.

Step 1: Confirm low testosterone the right way

For adult men, the Endocrine Society recommends diagnosing low testosterone (called hypogonadism) only when you have symptoms or signs consistent with testosterone deficiency and consistently low levels, confirmed with repeat early-morning fasting blood tests. One low number isn't a diagnosis. Neither is a quiz. If you work nights, tell your clinician — your sleep schedule can affect the timing of those tests.

Step 2: Settle fertility before you start

Testosterone from outside your body can lower sperm production. If you want kids soon, say so before treatment starts. That conversation may point you to a urologist or reproductive urologist instead of a standard TRT program. Our TRT and fertility guide covers questions to ask before treatment.

Step 3: Pick a care route that protects your card

For a commercial driver, the cheapest TRT plan isn't automatically the best one. Ask any provider — online or local — these four questions before you pay:

  1. Will your clinician complete FMCSA form MCSA-5895 or write a DOT prescriber letter? Is there a fee?
  2. Will a clinician actually know my history? Live video visits help here.
  3. How often do you check blood pressure and hematocrit?
  4. Can I download my lab results and records to bring to my exam?

One more timing note. Under the current DEA extension through December 31, 2026, DEA-registered practitioners may prescribe testosterone by audio-video telemedicine without a prior in-person evaluation when the applicable federal and state requirements are met. The prescription must have a legitimate medical purpose; the temporary rule does not make a questionnaire alone enough. Rules after that date may change. Ask any online provider how they'll handle it.

Step 4: Give yourself runway

Current testosterone labels advise periodic blood-pressure checks; follow the schedule for your product and your clinician's plan. Plan treatment, monitoring, and any requested records with your prescriber and examiner before your physical. There is no fixed TRT waiting period in the reviewed federal standard.

Who needs further evaluation before starting TRT: If your blood pressure is uncontrolled, you have untreated severe sleep apnea, your blood count runs high, you want children soon, or you've never had your testosterone properly tested, address that with an appropriate clinician first. Depending on the issue, primary care, urology, reproductive urology, endocrinology, or a sleep specialist may fit.

Not sure which route fits? Use TRT Provider Guide's Find My TRT Path tool to explore online TRT programs. Find My TRT Path → (It's an educational tool. It can't decide DOT qualification or replace your prescriber or examiner.)

When you're ready to start online

If you've had proper testing, your blood pressure is controlled, and online care fits your schedule on the road, confirm the documentation process before you pay. We have not verified whether any specific online TRT program completes MCSA-5895 or DOT letters. Ask question #1 above before you pay. If the clinician cannot provide the information your examiner requests, ask the examiner what other documentation would be acceptable.

Prices, states, and medication options change often, so confirm the full first-year cost — membership, medication, and labs — on each provider's own page. Ask about repeat tests, visit and paperwork fees, shipping, minimum commitments, cancellation, refunds, and access to your records before you pay. Our method for comparing providers is explained in How We Review TRT Providers.


Who should you contact about TRT and your medical card?

Your prescriber handles your treatment and the medical statement. Your certified medical examiner decides whether you qualify. Your carrier or state licensing agency explains company or state rules that apply to your driving.

TRT and DOT medical certification, risks and exam preparation table 8: Who should you contact about TRT and your medical card?
Your question Call this person first
"Could my medication or symptoms affect my driving?" Your prescriber; for sudden severe symptoms, see the emergency advice below
"What records do you need for my exam?" Your certified medical examiner's office
"Can you fill out MCSA-5895 or write a letter?" Your prescriber
"Am I interstate or intrastate? What's our company policy?" Your carrier
"What are my state's intrastate medical rules?" Your state DMV or licensing agency

Call 911 for severe chest pain or pressure, severe trouble breathing, sudden weakness on one side, or sudden trouble speaking. These are emergency symptoms; do not drive yourself for help.


FAQ: TRT and DOT physicals

TRT alone does not set your card length, a required testosterone level, or an automatic new-exam date. Medication disclosure and the full medical standards still apply.

Can you be on testosterone and have a CDL?

Yes. Prescribed testosterone isn't banned. The prescription exception in 49 CFR 391.41(b)(12) applies when your prescriber knows your history and advises it won't affect safe driving. The examiner makes the final decision.

Is testosterone a disqualifying medication for DOT?

Not automatically. FMCSA doesn't publish a banned-medication list. Schedule I use has no prescription exception. Testosterone is Schedule III and must meet the prescription exception; any medication can still prevent certification if it interferes with safe driving.

Does DOT test for testosterone?

No. The DOT drug panel covers marijuana, cocaine, amphetamines, opioids, and PCP only. Your employer may have separate non-DOT testing rules.

Do I have to tell the DOT doctor I'm on TRT?

Yes. The exam form asks about all medications and supplements, and you sign that your answers are true. Leaving it out can void your certificate.

Does TRT mean I'll only get a one-year card?

Not automatically. We found no TRT-specific card length in the federal standards. The normal maximum is 24 months. Your examiner sets the length based on your overall health, especially blood pressure.

Is there a testosterone level I have to hit to pass?

No. The federal physical standards don't include a testosterone level. Your treatment target is between you and your prescriber.

Are injections, gels, or pills treated differently at a DOT physical?

The rule doesn't favor one form of testosterone. Each product has its own risks, so talk to your prescriber. Don't switch forms just to try to get a card.

Can my online TRT doctor fill out my DOT paperwork?

Possibly. A licensed prescriber who knows your history can complete MCSA-5895 or write a letter. Ask before you sign up — we haven't verified which online programs do this.

Should I stop TRT before my physical?

No — don't change prescribed treatment on your own to influence an exam. Disclose it, bring your paperwork, and let your prescriber and examiner do their jobs.

What hematocrit is too high on TRT for DOT?

There's no DOT hematocrit cutoff in the federal standards. The Endocrine Society tells prescribers to pause therapy if hematocrit goes above 54%. Bring your latest result in case the examiner asks.

Do I need a new DOT physical when I start TRT?

The federal re-exam rules don't list starting TRT by itself as a trigger. But you're never allowed to drive when illness or fatigue makes it unsafe, under 49 CFR 392.3. A physical or mental injury or disease that impairs your ability to perform your normal duties does require re-examination under 49 CFR 391.45(g). Follow any instructions from your examiner or carrier.

Can I carry testosterone in my truck?

Federal DOT rules address on-duty drug possession and use under 49 CFR 392.4, including an exception for medication used under a licensed practitioner's instructions when the practitioner advises that it will not affect safe driving. As practical preparation, keep it in the original pharmacy-labeled container with your name on it, and keep a copy of your prescription. State rules on carrying controlled substances vary; ask your pharmacist about requirements and storage conditions for your route.
