A DOT physical exam is typically valid for up to two years. However, individuals with certain medical conditions like hypertension, diabetes, or sleep apnea may receive a certificate valid for only one year. If physical limitations such as severe back pain or visual and hearing impairments are detected, you may be referred to a specialist for additional evaluation or clearance. This process ensures that drivers can safely meet the requirements of both short-haul and long-haul trucking.

During a DOT physical, you can expect a comprehensive evaluation that includes a review of your medical history, visual acuity and color perception tests, a hearing test, blood pressure check, heart and lung evaluation, height and weight measurements, and a urinalysis (which is not a drug test).

The DOT physical exam is crucial for maintaining a commercial driver's license. The Federal Motor Carrier Safety Administration (FMCSA) mandates these exams to ensure commercial drivers are physically fit to operate vehicles safely. This requirement helps reduce the risk of incidents that could potentially harm the driver or the public.
