Motorcycle helmet and lane-splitting laws in Connecticut

If you ride in Connecticut, a handful of state rules apply to you that don't apply to the driver in the car next to you. They decide whether you were breaking a law when a crash happened, and that can shape what your injury claim is worth. Here is what the statutes actually say, with the section numbers and the exact fines.

Who has to wear a helmet

Connecticut has a partial helmet law. Under Conn. Gen. Stat. § 14-289g, no one under 18 may operate a motorcycle or ride as a passenger unless they are wearing protective headgear that meets the federal standard in 49 CFR 571.218, the DOT standard known as FMVSS 218. Break that rule and it is an infraction carrying a fine of not less than $90.¹

The flip side is what the statute leaves out. Riders 18 and older are not required to wear a helmet at all. The law also carves out autocycles, which it says are not motorcycles for this purpose.¹ So a 30-year-old on a Harley can legally ride bare-headed in Connecticut, while a 17-year-old on the same bike cannot.

Lane splitting is illegal

Riding between lanes of moving or stopped traffic, often called lane splitting, is against the law in Connecticut. Section 14-289b(b) says the operator of a motorcycle shall not operate it between lanes of traffic, and shall not overtake and pass another vehicle (anything other than a motorcycle) inside the same lane the motorcycle is already in.² A rider is entitled to the full use of a single lane, but no more than two motorcycles may ride abreast in one lane.² A violation is an infraction.²

Lawmakers have introduced bills to allow lane filtering in slow or stopped traffic, but none has become law, so the ban is in force in 2026. The same statute has two rules riders sometimes forget: any motorcycle built after January 1, 1980, has to run its headlight whenever it is being operated, and the between-lanes prohibition does not apply to a police officer on duty.²

Eye protection and passengers

Connecticut requires eye protection for the person actually driving the bike. Under § 14-289d, a motorcycle operator has to wear goggles, glasses, or a face shield that meets the DMV's specifications, and failing to do so is an infraction. There is one exception: the requirement does not apply if the motorcycle has a windshield or wind screen that meets those same specifications.³ The rule is written for the operator, not the passenger.

Two more rules sit in the same part of the code. You cannot ride sidesaddle, and you cannot carry a passenger on a motorcycle that was not designed to carry one. Either is an infraction under § 14-289c.⁴

How these rules affect an injury claim

Connecticut follows modified comparative negligence. Under § 52-572h(b), being partly at fault does not bar your recovery as long as your share of the negligence is not greater than the combined negligence of the people you are suing. If you are 50 percent at fault or less, you still recover, but your damages drop by your percentage of fault; cross the line to 51 percent and you recover nothing.⁵ The same statute abolished the old defenses of assumption of risk and last clear chance.⁵

That framework is where the helmet and eyewear rules can come back into a case. An insurer defending a claim will look at whether you were following the motorcycle statutes, and any percentage of fault a jury assigns to you is subtracted under § 52-572h. If the injured rider was under 18 and not wearing the headgear § 14-289g requires, expect the defense to raise it, and expect it to be argued as a question of fault rather than an automatic bar. It helps to understand the rules before an adjuster does. If you want help sorting out fault, thatcarhitme.com maintains a legal directory of attorneys.

The insurance that protects riders

Every Connecticut auto policy has to carry minimum liability limits of 25/50/25: $25,000 for bodily injury to one person, $50,000 per accident, and $25,000 for property damage, under the state's financial responsibility law.⁶ Those numbers go fast when a motorcyclist is seriously hurt.

That is why uninsured and underinsured motorist coverage matters so much on two wheels. Section 38a-336 requires every auto policy to include UM/UIM coverage equal to the driver's own liability limits, unless the named insured signs a state-approved form rejecting a lower amount in writing.⁷ If a driver with only minimum coverage puts you in the hospital, your own UM/UIM coverage is often what pays the difference. Connecticut also runs a pure tort system with no mandatory personal injury protection; the state repealed its no-fault law effective January 1, 1994.⁸

Deadlines and aggravating conduct

The clock on a Connecticut injury claim is set by § 52-584: two years from the date the injury is first sustained or discovered, or reasonably should have been discovered, with a hard outer limit of three years from the act that caused it.⁹ The same statute covers damage to your bike, so a property or diminished value in Connecticut claim runs on the same calendar.

Connecticut law also gives crash victims extra leverage against the worst drivers. Under § 14-295, a court may award double or treble damages when the driver deliberately or recklessly violated the DUI statute (§ 14-227a) or certain other traffic laws and that violation was a substantial factor in the crash.¹⁰ Distraction is a common cause of motorcycle crashes, and handheld phone use and texting are both banned in Connecticut with primary enforcement, so an officer can pull a driver over for that alone. Fines run $150 for a first offense, $300 for a second, and $500 for a third or later, under § 14-296aa.¹¹

Connecticut crash numbers

The risk is not abstract. Connecticut recorded 103,489 reported crashes statewide in 2025.¹² The pace has not eased in 2026: the state logged 1,737 crashes in March 2026 alone.¹³ If you were in one, the police report is the anchor document for any claim, and thatcarhitme.com covers how to get a Connecticut crash report.

Riding legal does not prevent a crash, but it keeps the other side from shifting blame onto you. Know which of these rules apply to your ride, keep your paperwork, and move before the two-year deadline closes.
