Compliance FAQ
Do I need a DOT physical every year?
No, the standard DOT medical examination certifies a driver for up to 24 months under 49 CFR §391.43. Most CDL holders and intrastate equivalents only renew every two years. Drivers with conditions that require closer monitoring - Stage 1 hypertension, diabetes managed on insulin, sleep apnea on a CPAP, or vision/hearing requiring follow-up - receive a shorter certification window of 3, 6, or 12 months at the medical examiner's discretion. The exam must be performed by a clinician listed on the FMCSA National Registry of Certified Medical Examiners, who electronically transmits the result to FMCSA the same day under the National Registry Phase 2 rule. The result automatically updates your CDLIS record so the state DMV has it for CDL renewals. You keep the paper copy of the medical examiner's certificate (MEC, form MCSA-5876) in the truck and in your DQ file.
Why it matters
A lapsed medical card means a non-qualified driver under 49 CFR §391.41. If a roadside inspector finds an expired MEC, the driver is placed out-of-service for the inspection cycle and the carrier takes a CSA Driver Fitness BASIC violation. The cost of an MEC ($100–$160 typical) is trivial next to the cost of a deadhead and the CSA hit, so most carriers schedule renewals 30–45 days before expiration.
The National Registry rule eliminated the old practice of carriers self-reporting medical-card status to the DMV. Examiners send results electronically; if the transmission fails or the examiner uses a non-Registered clinic, the CDL holder ends up with a state-DMV record showing “medically uncertified” even though they have the paper card in hand. Always confirm the examiner is on the FMCSA registry before booking.
Diabetic drivers on insulin and sleep-apnea drivers on CPAP must demonstrate adherence at every recertification.
