Who must wear a helmet in Connecticut, the penalties for not wearing one, and the eye-protection rules every rider should know.
Effective October 1, 2025, Connecticut law requires every person under 21 years old to wear protective headgear when operating — or riding as a passenger on — a motorcycle or a motor-driven cycle.
Connecticut also has a long-standing rule that no person under 18 may operate a motorcycle or motor-driven cycle, or ride as a passenger, unless wearing protective headgear. The 2025 law raises the helmet requirement to cover everyone under 21.
Every motorcycle operator and passenger under 21 must wear approved protective headgear. Licensed riders 21 and older are not legally required to wear a helmet.
There is one important exception: every motorcycle learner's permit holder, regardless of age, must wear USDOT- or NHTSA-approved protective headgear while operating a motorcycle. An adult on a permit cannot ride bare-headed even though a fully licensed adult could.
Operating or carrying a passenger in violation of Connecticut's headgear law is a traffic offense. A motorcycle operator must observe all Connecticut traffic laws, and any violation carries the same penalties and fines as for other motorists. Confirm current fine amounts with the Connecticut Department of Motor Vehicles.
The Connecticut Motorcycle Operator Manual strongly recommends face or eye protection: a plastic, shatter-resistant face shield helps protect your whole face, while goggles protect only your eyes. A windshield is not a substitute for a face shield or goggles.
Effective eye protection is free of scratches, resistant to penetration, gives a clear view to either side, and fastens securely. Do not wear tinted eye protection when little outside light is available, such as at night.
A legal motorcycle helmet must meet the U.S. Department of Transportation (DOT) FMVSS 218 standard. Look for the "DOT" certification label on the back. Helmets that meet stricter Snell or ECE standards offer additional protection. Avoid novelty helmets — they are not legal head protection.

The Connecticut Motorcycle Operator Manual (R-217, Rev. 10-25) states the knowledge exam has 16 questions; 12 correct (75%) are needed to pass. The exam is given by appointment only at a full-service DMV branch office.
