How often must a CDL holder renew their medical certificate?

A CDL holder is required to renew their medical certificate every two years. This requirement ensures that drivers maintain the necessary level of health to operate commercial vehicles safely. A valid medical certificate is crucial as it confirms that the driver does not have any medical conditions that could impair their ability to drive or increase the risk of accidents.

While some medical conditions may require more frequent evaluations, the standard renewal period of every two years allows for consistent monitoring of the driver’s health without being overly burdensome. In some cases, a driver may need to submit medical documentation more often based on their health status, but the general rule is every two years.
