When must a driver have a medical examination according to DOT regulations?

A driver must undergo a medical examination according to DOT regulations at least every two years, unless a medical examiner specifies a different timeframe based on the driver's individual health circumstances. This requirement is in place to ensure that commercial drivers maintain the necessary health standards to operate a vehicle safely. Regular examinations are designed to identify any potential health issues that could impair driving ability, allowing for early intervention and ensuring public safety on the roads.

While some drivers may have specific conditions that necessitate more frequent evaluations, the general rule is the biennial requirement, which provides a standard for compliance across the industry. This systematic approach helps maintain an up-to-date assessment of drivers' health and fitness to drive commercially.
