DOT Exam Information
Commercial drivers (and non-CDL drivers that operate a commercial vehicle) are required to have a medical certificate.
A DOT physical exam is valid for up to 24 months. The medical examiner may also issue a medical examiner’s certificate for less than 24 months when it is desirable to monitor a condition, such as high blood pressure.
A typical DOT exam takes anywhere from 45-60 minutes to complete.
