A DOT physical is a medical examination required by the Federal Motor Carrier Safety Administration (FMCSA) for commercial drivers. This exam evaluates a driver’s physical and mental fitness to safely operate CMVs, such as semi-trucks, buses, and vehicles transporting hazardous materials.
Since commercial driving involves long hours on the road, strenuous conditions, and potential hazards, DOT physicals help ensure drivers are in optimal health to prevent accidents caused by medical conditions.
For example, you must be able to hear surrounding sounds, read road signs clearly, and remain alert. Certain health conditions or medications can impact these abilities, while others may increase the risk of medical emergencies that could compromise your safety and that of others on the road. Therefore, a DOT physical is important for both personal and public safety.
