DOT certification is a process that verifies an individuals qualifications, skills, or knowledge required to perform services related to commercial vehicles. It is a seal of approval that shows that the individual is physically, mentally, and emotionally fit to operate a commercial vehicle. DOT certification is required for commercial drivers to ensure the safety of the public.

To obtain DOT certification, an individual must pass a DOT medical exam and, depending on the states regulations, a series of safe-driving exams. The medical exam must be conducted by a licensed medical examiner listed on the Federal Motor Carrier Safety Administration (FMCSA) National Registry. The exam is valid for up to 24 months, and the medical examiner may issue a medical examiners certificate for less than 24 months when it is desirable to monitor a condition, such as high blood pressure.

DOT certification is required for individuals who drive a vehicle designed to carry more than 15 people, are paid to drive a vehicle designed to carry more than 8 people, or carry hazardous material in their vehicle that requires their vehicle to have a placard.

It is important to note that each state has its own rules regarding DOT certification, so it is essential to check with the local DMV for additional information.
