Coming in for a DOT physical can feel like a high-stakes exam, especially if your livelihood depends on the medical card. The good news: most drivers pass on the first try, and a little preparation makes the appointment dramatically smoother. Here’s exactly what to do the week before, the day before, and the morning of your DOT physical.

What is a DOT physical, exactly?

A DOT physical (also called a DOT medical exam or CDL physical) is a federally required health screening conducted by a Certified Medical Examiner from the FMCSA’s National Registry (NRCME). If you pass, you’re issued a Medical Examiner’s Certificate, your “med card”, valid for up to 24 months.

Bring these documents to your appointment

  • Government-issued photo ID (driver’s license is fine)
  • Your current medical card, if you have one
  • A list of all medications you take (prescription and over-the-counter), with dosages
  • Eyeglasses or contacts you wear for driving
  • Hearing aids if you use them
  • If you have any of these conditions, bring documentation:
    • Diabetes, most recent A1C and a note from your treating physician
    • Sleep apnea, a current CPAP compliance report (90 days of usage at 4+ hrs/night)
    • Hypertension, recent BP log and medication list
    • Heart conditions, most recent stress test, EKG, or specialist clearance
    • Vision issues, most recent eye exam if you wear corrective lenses

The week before

  • Keep blood pressure in check, limit caffeine, alcohol, and salt
  • If you’re on BP meds, take them as prescribed (don’t skip)
  • Drink plenty of water, your urine sample is part of the exam
  • Get a few solid nights of sleep
  • If you wear glasses or hearing aids, make sure they’re with you

The day before

  • Avoid heavy salt, caffeine, and energy drinks
  • Skip alcohol entirely
  • Eat a normal dinner, don’t fast (it can spike your blood pressure the next morning)
  • Get 7–8 hours of sleep

The morning of

  • Eat a light, balanced breakfast
  • Drink water but not gallons, you need to provide a urine sample but you don’t need to overdo it
  • Skip caffeine if you can, it elevates blood pressure
  • Take all your regular medications
  • Arrive 10 minutes early with your paperwork

What happens at the exam

  1. You fill out the FMCSA medical history form (we’ll help you complete it)
  2. Vital signs, height, weight, blood pressure, pulse
  3. Vision and hearing screens
  4. Urinalysis (not a drug test, just basic dipstick: protein, sugar, blood)
  5. Physical exam, heart, lungs, abdomen, neuro, musculoskeletal
  6. Examiner reviews everything and issues your med card

Total time at Total Tox: usually 30–45 minutes start to finish, including walk-in wait.

If you fail or get a short card

Don’t panic. A 30- or 90-day temporary card is common for borderline blood pressure, untreated sleep apnea, or pending specialist documentation. Get the documentation, come back, and you can be re-evaluated, sometimes the same week.
