Winter & Snow/Ice Accident Claims in Connecticut

Connecticut recorded 103,489 crashes statewide in 2025, and the pace hasn't slowed heading into this winter.¹ March 2026 alone logged 1,737 crashes across the state.² Winter months consistently run hotter than they should for crash counts. In Greenwich, February 2025 saw 129 reported crashes, compared with just 32 in May 2026, a gap that tracks with icy roads, shorter daylight, and holiday travel.³⁴

If a snowstorm, black ice, or a skidding car put you in the hospital this winter, Connecticut law treats your claim differently depending on what caused it. The rules below are specific to this state: the deadlines, the agencies, and a few traps that catch people who assume the same rules apply everywhere.

Fault still has to add up to something

Connecticut is an at-fault, modified comparative negligence state. You can recover damages as long as you're found 50% or less at fault for the crash; your award just gets reduced by your percentage of fault. Cross the 51% line and you recover nothing.⁵ Winter crashes make this calculation messier than a clear-day rear-ender, because a jury or adjuster has to sort out how much of the crash came from another driver's choices and how much came from the road itself.

That's where Connecticut's traveling-unreasonably-fast statute does a lot of work. Conn. Gen. Stat. § 14-218a doesn't just punish drivers who beat the posted limit. It makes it illegal to drive faster than is reasonable, "having regard to the width, traffic and use of the highway... and weather conditions." A driver doing 25 in a 35 zone can still be cited, and found at fault, if that speed was unsafe for the snow on the ground.⁶ Police use this statute constantly after winter wrecks, and a citation under it is strong evidence in a civil claim even though it doesn't decide the case by itself.

Uninsured and underinsured coverage matters more in a whiteout

Hit-and-runs go up in bad weather. Someone spins out, clips you, and drives off before you can get a plate number, or the driver who hit you is carrying only the state minimum. Connecticut requires every auto policy to include uninsured and underinsured motorist coverage equal to the driver's own liability limits, with a floor of $25,000 per person and $50,000 per accident, unless the policyholder rejected a lower amount in writing on a signed, commissioner-approved form.⁷ The state's minimum liability limits are 25/50/25 for bodily injury and property damage, so plenty of drivers on the road are carrying only that floor.⁸ If your own UM/UIM coverage is thin, or was waived at some point, check the policy before assuming the other driver's insurance will cover a serious injury.

When the road itself is the problem

A lot of winter crashes aren't really about who braked too late. They're about a road that should have been plowed, sanded, or salted and wasn't. Suing a town or the state over that is a different legal animal from suing another driver, and Connecticut's version has sharp edges.

Claims against a municipality for an unsafe road, including one made dangerous by snow or ice, run through Conn. Gen. Stat. § 13a-149, the state's highway defect statute. You must give written notice, including a description of the defect, its cause, and the time and place of the injury, to a selectman or the town or city clerk within 90 days of the crash. Miss that window and the claim is gone, regardless of how strong it otherwise is. The lawsuit itself must be filed within two years of the injury, a flat deadline that runs on a different clock than Connecticut's general two-year discovery rule for ordinary negligence claims.⁹¹⁰

The bigger trap is what the Connecticut Supreme Court has said this statute requires. In Sanzone v. Board of Police Commissioners, the court held that § 13a-149 is a plaintiff's exclusive remedy against a municipality for a defective road, and that the defect must be the sole proximate cause of the injury.¹¹ That means the claim fails if your own driving contributed at all, or even if a third driver's negligence played a role. In a multi-car pileup where an unplowed road and a following driver's speed both contributed, that second cause can wipe out a claim against the town entirely, even though ordinary comparative negligence law would simply reduce your recovery instead.

State-maintained highways run through a parallel statute, Conn. Gen. Stat. § 13a-144, which lets you sue the Commissioner of Transportation directly in Superior Court.¹² That's unusual for a claim against the state; it bypasses the Claims Commissioner process that most claims against Connecticut require. The same 90-day written notice rule applies, this time sent to the commissioner rather than a town clerk.

Towns and the state also get the benefit of the ongoing storm doctrine. Connecticut courts have long held that a party responsible for keeping a walk or road safe may wait out a storm, and a reasonable time afterward, before it's on the hook for ice or snow that accumulated during it.¹³ That reasonable-time window is fact-specific: how bad the storm was, how long it lasted, and how much time passed before your crash all matter. It doesn't cover ice that was already there before the storm started.

Studded tires and the seasonal window

Connecticut allows studded tires and tire chains only from November 15 through April 30.¹⁴ Outside that window, a first violation is an infraction with no fine; a second carries a fine of up to $200. It's a narrow point, but it can matter for fault: a car running metal studs illegally in October, or bald tires in a January storm, is evidence a jury can weigh.

Drunk driving and holiday crashes

Winter brings holiday parties and DUI crashes. Connecticut lets a victim seek double or treble damages against a driver who deliberately or recklessly drove drunk, in violation of § 14-227a, if that violation substantially caused the crash.¹⁵ Separately, a bar or seller can be held liable under the state's Dram Shop Act for serving a visibly intoxicated adult, though total recovery from the seller is capped at $250,000 per injured person and $250,000 in the aggregate.¹⁶

After the crash

Get a copy of the official report; our Connecticut crash report guide covers how that works. If your car took damage in a slide or fender-bender and you're weighing a diminished value claim, that has its own rules, covered in our Connecticut diminished value guide. And if you're dealing with a claim against a municipality, the state, or an insurer disputing fault in icy conditions, it's worth talking to an attorney who handles Connecticut crash claims. Our legal directory is a place to start.
