Minnesota Winter & Snow/Ice Accident Claims Guide

Minnesota gets roughly four months a year where a clear road can turn to glare ice with no warning, and the law hasn't ignored that. Drivers owe each other the same duty of care they do in July, but a storm changes what "reasonable" means, and it opens up a narrow set of claims against cities, counties, and the state that don't exist the rest of the year. Anyone hurt in an ordinary Minnesota crash gets six years to sue a private driver for personal injury.¹ A crash tied to a government plow route or an unsalted state highway can shrink that window to 180 days, a detail that catches a lot of people who assume they have plenty of time.²

Speed limits are a ceiling, not a target, once snow falls

Minnesota's basic speed law doesn't stop at the posted number. Every driver has to keep speed "reasonable and prudent under the conditions," and the statute separately requires reduced speed whenever "special hazards exist with respect to pedestrians or other traffic or by reason of weather or highway conditions."³ A driver going 55 in a 55 zone during a snow squall isn't automatically in the clear. If visibility or footing made that speed unsafe, the driver was still going too fast under Minnesota law, regardless of the sign. Insurance adjusters and juries lean on this distinction constantly in winter cases: the posted number is the legal ceiling, not proof that a given speed was safe that day.

Following too closely turns ice into your fault

A large share of Minnesota's winter crashes are chain-reaction rear-enders: one car brakes on a slick patch and the cars behind it can't stop in time. Minnesota law puts the burden on the trailing driver, who can't follow more closely than the speed, traffic, and highway conditions make reasonable and prudent.⁴ On dry pavement that might mean a couple of car lengths. On packed snow or black ice, it means a lot more room, and a driver who rear-ends someone during a storm usually can't point to the weather as an excuse, since the statute already builds weather into what counts as a safe following distance.

That doesn't end the analysis, though. Minnesota is a modified comparative fault state: an injured driver can still recover as long as they're 51% or less at fault, so if the lead vehicle stopped for no reason or had broken brake lights, fault can shift back toward it.⁵

When a government plow or an unplowed road caused the crash

This is where Minnesota's winter rules diverge sharply from the rest of the year. Cities and counties are immune from claims based on snow or ice conditions on a highway or public sidewalk, unless the government itself affirmatively caused the condition.⁶ Nearly identical wording protects the state and MnDOT.⁷ In practice, a lawsuit arguing that a county should have plowed a road sooner almost always fails: deciding which roads get plowed first, and when, is a discretionary policy call that Minnesota law separately shields from being second-guessed in court.⁸

The exception is narrower but real. A plow operator's own negligence that creates a hazard counts as affirmative conduct. Simply not getting to a road yet does not. A plow that piles snow into a ridge blocking a marked crosswalk, a city truck that runs a stop sign, or a crew that applies de-icer in a way that creates a refreeze hazard on an otherwise clear stretch can fall outside the immunity. Even when a claim like that succeeds, recovery against a city, county, or the state stays capped at $500,000 per claimant and $1,500,000 per occurrence, well below what a suit against a private driver can recover.⁹

The 180-day deadline that catches people off guard

Whatever the theory, a claim against a municipality or the state starts with a notice, not a lawsuit. Minnesota law requires written notice to the governing body within 180 days of the loss, describing what happened, where, and who was involved.² The state tort claims act imposes the identical 180-day notice requirement for claims against MnDOT or other state agencies.¹⁰ Miss that window and the claim is generally gone, even though the same crash against a private driver would still be well within the six-year statute of limitations.¹ Anyone who suspects a plow, a city truck, or a road-maintenance decision played a role in a winter crash should get that notice filed early rather than waiting to see how injuries develop. A Minnesota attorney from the legal directory who handles government-liability claims can help identify the right agency and draft the notice correctly.

Studded tires are illegal here, chains aren't

Minnesota residents can't run studded tires at any time of year.¹¹ The only exception covers out-of-state visitors whose home state allows studs, and even then only for occasional use, defined as no more than 30 days in a six-month period.¹¹ What the same statute allows for any driver is tire chains "of reasonable proportions" when needed because of snow, ice, or other conditions that tend to cause skidding.¹¹ It matters in fault disputes: a driver who didn't chain up before an obviously ice-glazed stretch wasn't violating the studded-tire ban, since chains were always a legal option, but a court can still weigh what equipment a reasonable driver would have used against the speed-for-conditions standard above.

Sharing the road with snowplows

MnDOT runs roughly 800 plows to cover about 12,000 centerline miles, more than 30,500 lane miles, and a single rural route can take up to eight hours to finish.¹² Minnesota's move-over law requires drivers to shift a full lane away from a stopped road-maintenance vehicle running its warning lights, the same duty that applies to a stopped tow truck or utility vehicle.¹³ That duty is specific to a plow that's stopped or parked. It doesn't create a separate law against passing an active, moving plow, though passing one remains a bad idea: wing plows can extend two to ten feet past the truck, visibility drops fast in the snow cloud behind one, and MnDOT reports that most vehicle-versus-plow crashes happen when a driver rear-ends a plow or clips it while passing.¹²

Uninsured drivers, black ice, and vehicle damage

Whiteouts and black ice raise the odds of a driver who can't be identified, or doesn't carry adequate coverage, sliding across a median and clipping a car before anyone gets a plate number. Minnesota requires every registered vehicle to carry uninsured and underinsured motorist coverage of at least $25,000 per person and $50,000 per accident, coverage that pays out regardless of who caused the crash or whether the other driver is ever found.¹⁴ No-fault PIP benefits work the same way in a snowstorm as in July: your own insurer covers medical bills and lost wages up to Minnesota's basic economic loss limits regardless of fault.¹⁵ If a plow, a sliding car, or a parking-lot mishap left your vehicle structurally sound but worth less at resale, that's a separate diminished value claim under Minnesota law.

Getting the official crash report matters in almost any winter case, since the road and weather conditions the responding officer recorded at the scene often become the central fact question later. Anyone unsure whether a case involves a private driver, a government plow route, or both should talk to an attorney early, given how much shorter the government notice deadline is than most people assume.
