Connecticut’s New Bicycle Helmet Laws

 Posted on May 21, 2026 in Bicycle Accidents

As people across the state hit the road on their bikes, it is important to remember the new helmet laws that recently went into effect. Last fall, the state expanded who has to wear a helmet on a bicycle, an e-bike, a motorcycle, a scooter, or a skateboard. The changes increase the safety rules for many people.

Who Has to Wear a Helmet on a Bicycle in Connecticut Now

Before October 2025, Connecticut required helmets only for bicycle, scooter, and skateboard riders under 16. That age threshold has been raised, and a separate rule was added for e-bikes. The rules now look like this:

• Bicycle, scooter, and skateboard riders under 18 must wear a helmet (the old age was 16)
• Every rider on an e-bike must wear a helmet, regardless of age
• Motorcycle riders and passengers must wear a helmet until age 21 (the old age was 18)

Fines for violating this rule begin at $90. The more important reason to follow the rule, though, is the safety that helmets provide. Head injuries are by far the most serious injuries in any kind of bike crash, and even a low-speed fall on pavement can cause a concussion or more serious injury. A helmet does not prevent a collision, but it can change the kind of injury someone walks away with.

Why Connecticut Expanded the Bicycle and E-Bike Helmet Rule

The state did not raise the helmet requirements in a vacuum. The expanded helmet rule for traditional bicycles matches what pediatricians and emergency physicians have been recommending for years. Teenagers ride differently than younger children. They go farther, faster, and more often without an adult nearby. A helmet rule that ended at 16 left out an age group that still needs to be protected.

What the Helmet Rule Means for Fault if a Rider Is Hurt in an Accident

If you are hurt in a bike crash, the question of who was at fault still depends on the facts of the crash itself. A driver who turned without looking, opened a car door into a bike lane, or ran a stop sign is responsible for that conduct, whether or not the rider was wearing a helmet.

Connecticut follows modified comparative negligence, which means a person’s monetary recovery can be reduced if their own conduct contributed to their injuries. In a bike or e-bike case, an insurance company may try to argue that not wearing a helmet contributed to a head injury. Whether that argument has any weight depends on the facts of the case and how the issue is treated by the court.

Helmet Safety Tips Worth a Refresher

Bike Safety Month is a good time to look at the helmet that has been sitting in the garage all winter and ask whether it is still doing its job. A few things to check:

• Fit: the helmet should sit level on the head, about two finger-widths above the eyebrows, with straps forming a Y under each ear and a snug chin strap
• Age: helmets break down over time and after any serious impact, and most manufacturers recommend replacing them every five years or after a crash
• Type: those moving at higher speeds may want a helmet rated for higher-speed use, sometimes labeled NTA-8776, rather than a basic bike helmet
• Children: kids grow, and last year’s helmet may not fit the same way this year

For families, a review of helmet safety is also a useful moment to talk through where children are allowed to ride, what hand signals they should use, and what to do if they are in a crash.

What to Do If You Are Hurt in a Bicycle Crash

Bike injuries can range from scrapes and bruises to severe injuries. The first step after any crash is medical attention, even if you feel fine at first. Some injuries take hours or days to fully appear.

After medical care, a few practical steps can help protect your options:

• File a police report so there is an official record of what happened
• Take photos of the bike, any other vehicles, the scene, and any visible injuries
• Get the names and contact information of any witnesses
• Be careful about giving recorded statements to an insurance company before you understand your situation

Insurance questions after a bike crash can be more involved than they look. Coverage may come from the at-fault driver’s auto policy, from a household auto policy with uninsured or underinsured motorist coverage, or in some cases from a homeowner’s policy. An attorney can help you sort through which policies apply.
