How often must CDL medical certificates be renewed?

• A. Every 1 year
• B. Every 3 years
• C. Every 5 years
• D. Every 2 years

Answer: (D)

CDL medical certificates show you meet the medical standards to operate a commercial vehicle. For most drivers, this certificate is valid for two years, so you would renew it every two years. The expiration date is listed on the certificate itself, and you’ll need to renew before that date to stay compliant. There are exceptions: certain medical conditions or treatments can lead to a shorter certification period, such as one year, requiring more frequent renewals. But the common, standard interval is two years.
