FMCSA COVID-19 Waivers
Colorado is extending the FMCSA waiver for expiring Medical Examiners Certification (MEC). Commercial drivers who have a MEC expiring March 1, 2020 through November 30, 2021 will not be downgraded due to an expired MEC, provided they have proof of a valid medical certification and any required medical variance (as defined in 49 CFR 390.5T such as an exemption letter or a skill performance evaluation certificate) issued for a period of 90 days or longer and expired on or after March 1, 2020.
All new license applications and license renewals will require a valid unexpired MEC.
