What Is DOT Physical?

Medical exam for commercial drivers. A plain-English trucking glossary entry for owner operators and small fleets.

DOT Physical: A DOT physical is a medical exam performed by a certified medical examiner listed on the National Registry to confirm that a commercial driver is healthy enough to drive safely. It results in a medical examiner’s certificate.

Why it matters to owner operators

You need a valid medical certificate to drive a commercial vehicle. How long it lasts depends on the exam results, up to two years.

Example

A driver schedules the exam a few weeks before the current certificate expires.
