Connecticut CDL Renewal Process and Requirements

Renewing your Commercial Driver’s License (CDL) in Connecticut involves several important steps, deadlines, and documents. It’s crucial for commercial drivers to stay compliant with state and federal regulations to avoid penalties or loss of licensure. Here’s what you need to know to renew your CDL in Connecticut efficiently and legally.

When to Renew Your CDL

Connecticut CDLs are generally valid for 8 years. The Connecticut Department of Motor Vehicles (DMV) sends out a renewal notice approximately 60 days before your license expires. However, it's your responsibility to renew on time even if you don’t receive a notice.

You may renew your CDL up to 1 year before the expiration date. If you let your license expire, you must not operate a commercial vehicle and may be subject to additional fees or retesting requirements.

Eligibility and Requirements

To be eligible for renewal, you must:

• Hold a valid, unexpired Connecticut CDL
• Be a U.S. citizen or have lawful permanent residency
• Meet all medical and vision requirements
• Not have any disqualifying convictions or suspensions

Medical Certification

All CDL holders must have a current Medical Examiner’s Certificate (DOT card). The certificate must be valid and on file with the DMV. If your medical certificate is not up-to-date, your CDL could be downgraded to a non-commercial license.

You can find more details about medical certification requirements from the Federal Motor Carrier Safety Administration (FMCSA).

How to Renew

CDL renewal in Connecticut must be done in person at a DMV Hub Office or participating AAA location (if you're a AAA member). Appointments are strongly encouraged.

1. Make an Appointment: Schedule online through the CT DMV portal.
2. Gather Required Documents:
