Winter and snow/ice accident claims in Massachusetts

Massachusetts logged 128,769 crashes statewide in 2025¹. A meaningful share of those happen on the kind of roads this state deals with for roughly five months a year: packed snow, refrozen slush, and black ice that looks like wet pavement until a tire finds it. The Boston/Norton weather station puts average annual snowfall across eastern Massachusetts at 49.2 inches², and the Berkshires see considerably more. Winter's aftermath lingers, too. Boston alone still logged 451 crashes in April 2026³, well after the last storm, a reminder that frost-heaved pavement and faded lane markings keep causing wrecks long after the plows go home.

If you were hurt in a Massachusetts crash tied to snow or ice, the rules that decide who pays aren't the same ones you'd find in a dry-pavement fender bender. Here's what's specific to this state.

Weather doesn't excuse the driver

Massachusetts law doesn't treat "the roads were icy" as a defense. Under M.G.L. c. 90, § 17, drivers must decrease their speed "when a special hazard exists... by reason of weather or highway conditions," regardless of the posted limit⁴. Doing 40 in a 40 zone during a squall can still count as negligent driving under this statute. That matters because Massachusetts uses modified comparative negligence: a plaintiff can recover as long as their own fault doesn't exceed the other side's, but a jury that finds you 51% responsible for driving too fast for conditions bars your recovery entirely, and any lower share just reduces the award proportionally (M.G.L. c. 231, § 85)⁵.

Multi-car pileups and the limits of your coverage

Whiteout conditions on I-90 or Route 24 tend to produce chain-reaction crashes with far more vehicles than a typical two-car collision, and that's where the state's insurance minimums start to matter. Since July 1, 2025, drivers must carry at least $25,000 per person and $50,000 per accident in bodily injury liability, plus $30,000 in property damage (Acts of 2024, c. 275, amending M.G.L. c. 90, § 34A)⁶. In a ten-car pileup, that $50,000 per-accident cap can end up split among everyone hurt, which often isn't enough to go around. Uninsured motorist coverage at those same limits is mandatory on every Massachusetts auto policy (M.G.L. c. 175, § 113L)⁷, and it can step in for a driver who fled the scene or carried no policy at all. Underinsured motorist coverage is optional. Insurers have to offer it, but drivers can decline it in writing, so it's worth checking your own declarations page before assuming you're covered once the at-fault driver's policy runs out.

PIP pays first, no matter whose tires lost traction

Because Massachusetts is a no-fault state, your own insurer's personal injury protection pays your medical bills up to $8,000 regardless of who caused the skid (M.G.L. c. 90, § 34M)⁸. The insurer has to start paying within 10 days of getting notice from a treating provider, or send written notice denying the claim. PIP is also why most minor winter fender benders never turn into lawsuits: you can't sue for pain and suffering unless your reasonable medical expenses exceed $2,000, unless the crash caused death, a fracture, permanent disfigurement, or loss of sight or hearing (M.G.L. c. 231, § 6D)⁹. A soft-tissue injury from a low-speed slide into a snowbank often won't clear that bar. A fractured wrist from the same crash will.

When someone else's snow causes your crash

Ice chunks and rooftop snow flying off another vehicle are a real hazard on Massachusetts highways, and there's an actual statute behind the citations troopers hand out for it. M.G.L. c. 85, § 36 requires loads to be secured so nothing can drop, sift, or blow off a vehicle, with fines of $50 to $200 for violations¹⁰. If a chunk of ice off a truck's roof cracks your windshield, or forces a swerve that causes a crash, that citation is evidence of negligence you can point to. The reverse applies too: driving with a windshield so iced or snow-caked that it blocks your view is its own violation under M.G.L. c. 90, § 13, which bars operating a vehicle with anything that interferes with its proper operation¹¹.

Suing a town for an unplowed road

Rarely, and the law is written to make sure of it. M.G.L. c. 84, § 17 says a county, city, or town isn't liable for injuries caused by snow or ice on a public way if the location was "otherwise reasonably safe and convenient for travelers" at the time¹². In practice, that means pure snow and ice accumulation on a public road almost never supports a claim against a municipality by itself. What can support a claim is an underlying defect, a pothole, a broken drain that turns into a skating rink, a malfunctioning signal, combined with the ice. Even then, damages against a city or town for a public way defect are capped at $5,000, or one-fifth of one percent of the municipality's state property valuation, whichever is lower (M.G.L. c. 84, § 15)¹³. And you have to move fast: written notice naming the time, place, and cause of the injury is due within 30 days (M.G.L. c. 84, § 18)¹⁴. Snow and ice claims get one break other public-way claims don't: missing that window isn't automatically fatal unless the town can prove the late notice actually prejudiced its defense¹⁴. Part of why courts give municipalities this much room is scale. MassDOT's 2025-2026 snow and ice control agreement covers roughly 16,100 lane miles at an average cost of about $6,000 per lane mile each season¹⁵, and that's before counting what individual cities and towns spend on their own streets.

Parking lots and private ways play by a different rule

Private landowners don't get the municipal immunity above. Since the Supreme Judicial Court's 2010 decision in Papadopoulos v. Target Corp., property owners owe the same duty of reasonable care for snow and ice that they owe for any other hazard on the property, and can no longer hide behind the old distinction between "natural" accumulation (no duty to clear it) and "unnatural" accumulation (a duty)¹⁶. That case arose from a parking lot fall, and it's directly relevant if you were struck backing out of a poorly cleared lot, if a plowed snow berm blocked your sightline before a collision, or if you were hurt getting out of your car after a crash because the lot itself was never touched. Many cities layer their own rules on top. Boston, for one, requires property owners to clear sidewalks and curb ramps within three hours after snow stops falling (or three hours after sunrise, if it fell overnight), and fines noncompliance on a sliding scale: $200 for commercial properties, $100 for larger residential buildings, $50 for smaller ones, with separate fines for pushing snow back into the street¹⁷.

Deadlines and next steps

Whatever caused the crash, you generally have three years from the date of the collision to file a personal injury or property damage suit in Massachusetts (M.G.L. c. 260, § 2A)¹⁸, separate from the much shorter 30-day notice window that applies specifically to claims against a city or town. If you need the official report, crash reports in Massachusetts covers how to get one. If the crash left your vehicle worth less even after a full repair, see diminished value claims in Massachusetts. And if you're weighing whether to bring in a lawyer, especially with a multi-vehicle pileup, a municipal notice deadline, or a dispute over the PIP threshold, the legal directory is a place to start.
