The DOT physical is a medical exam — performed by an FMCSA-certified medical examiner — that certifies you're healthy enough to operate a commercial vehicle. It typically costs $50–$150, takes under an hour, and most applicants pass. You'll need it around the time you apply for your commercial learner's permit, so here's what happens in the room, what to bring, and the concerns that trip people up.
Where it fits in your CDL timeline
Most states require your medical examiner's certificate (the "DOT medical card") when you apply for your CLP. ELDT is independent of it — so the efficient sequence is: book the physical, complete your $20 ELDT theory online while you wait for the appointment, then walk into the licensing agency with both the medical card and your registry-reported training. The full sequence is in How to Get a CDL.
What the examiner checks
- Vision and hearing — including standards for distance vision and the ability to hear a forced whisper; glasses, contacts, and hearing aids are generally fine.
- Blood pressure and pulse — the most common stumbling block; higher readings can mean a shorter certificate or a follow-up requirement rather than a pass.
- Urinalysis — checking sugar and protein as health indicators (this is not the DOT drug test; that's a separate, employer-side requirement).
- General exam — heart, lungs, neurological function, range of motion, hernias, and your medical history, including medications and conditions like diabetes or sleep apnea.
What to bring
- Photo ID, and your glasses/contacts or hearing aids if you use them.
- A complete list of medications with dosages and prescribing doctors.
- Records for managed conditions — recent readings if you're treated for blood pressure or diabetes, CPAP compliance data if you're treated for sleep apnea. Documentation turns "maybe" into a longer certificate.
Passing when you have a condition
A managed condition usually means a monitored certification, not a rejection. Treated hypertension, controlled diabetes, and CPAP-compliant sleep apnea are everyday certifications for examiners — the pattern is simply shorter certificate periods with proof of management. If you know you're borderline on something, spend two weeks with your regular doctor getting it documented before the DOT exam; it's the highest-ROI prep there is.
One warning
Use a certified examiner — the FMCSA maintains a national registry of them, and licensing agencies only accept certificates from listed examiners. Any legitimate occupational-health clinic will confirm their examiner's registry status. It's the same lesson as ELDT training: the registry is the credential, whether it's your training provider or your doctor.

Typically $50–$150 depending on the clinic. Urgent-care chains, occupational-health clinics, and some pharmacies offer them; some employers reimburse or provide them free during onboarding.
Up to 24 months. Examiners can issue shorter certificates (commonly 12 months, sometimes 3 months) when a condition like high blood pressure needs monitoring.
High readings can shorten your certificate or require follow-up rather than automatically disqualifying you — thresholds determine whether you get 24 months, 12 months, or need treatment first. If you're borderline, see your regular doctor before the exam.
No — the two are independent. Most states require the medical certificate when you apply for your CLP, while ELDT theory can be done anytime before your skills test. Doing the $20 online theory while you wait for a physical appointment is the efficient order.
