Overview - Medical Card Renewal in Groton, Connecticut

CDL medical card compliance in Connecticut is one of the most frequently-cited violations during DOT inspections.

The Connecticut Department of Motor Vehicles actively enforces Medical Card Renewal regulations across Connecticut's 5 inspection stations and through mobile enforcement units that can appear on any route. Fleet owners in Groton operating routes through Connecticut should treat compliance as an ongoing operational priority, not a one-time task.
