The Federal Motor Carrier Safety Administration has extended a waiver that gives truck drivers additional time to renew their expired CDLs and medical certificates due to the COVID-19 coronavirus pandemic.

Drivers now have until Sept. 30 to renew licenses and certificates that expired on or after March 1. The initial waiver, granted March 24, extended the expiration dates until June 30.

In addition to CDLs and medical certificates, the waiver also includes commercial learner’s permits, extending the validity period for CLP holders without requiring them to retake the general and endorsement knowledge tests.

States, CDL holders, CLP holders, and interstate non-CDL commercial drivers are covered under the waiver, FMCSA says.

The agency says truckers have had difficulty scheduling DOT physicals and driver’s license renewals due to the ongoing COVID-19 pandemic.
