Massachusetts Studded Tire Law: Season, Exceptions, and Chains

Under Massachusetts studded tire law, metal studded tires are legal on public roads only from November 1 through April 30. Driving on them the rest of the year carries a fine of up to $50 and will cause your vehicle to fail its state safety inspection.¹

The Legal Window

Massachusetts General Laws Chapter 90, Section 16 prohibits operating a motor vehicle with metal studded tires on any public way between May 1 and November 1.¹ Read the other way, that leaves November 1 through April 30 as the legal season. The rule covers every public road in the Commonwealth, state highways and local streets alike.

The statute is written as a warm-weather ban rather than a winter permit. There is no registration step, no sticker, no tag. You just have to have the studs off the vehicle before May 1 and keep them off until November 1.

Fines and the Inspection Problem

A violation carries a fine of up to $50.¹ The bigger consequence usually shows up at the annual safety inspection. Between May 1 and November 1, studded tires are a rejection item, so a vehicle with studs still mounted during that period will fail.² A rejection sticker gives you 60 days to fix the problem and return for re-inspection. Waiting until late April to swap tires can turn a small chore into a scramble.

Exceptions

The statute allows two narrow exceptions, and neither creates a general-purpose workaround for drivers.

A duly authorized person operating an emergency fire vehicle may use studded tires year-round. The law names fire apparatus specifically. It does not extend to police cruisers, ambulances, or other emergency responders.¹
The Registrar of Motor Vehicles may authorize studded tire use before November 1 when weather demands it. This power sits with the Registrar and would come into play during an early ice storm, not on an individual basis.¹

Nothing in Section 16 lets MassDOT issue personal permits for out-of-season studded tire use, and there is no published process for a driver to request a private waiver from the Registrar.

Chains and Studless Winter Tires

Chains of reasonable proportions are allowed when snow, ice, or other slippery conditions make them necessary for safety. They have no fixed season because they are expected to come off once the road clears. The state does not require chains at any time, so carrying them is a driver’s choice.

Studless winter tires are legal year-round in Massachusetts. No statute restricts them, and they avoid the seasonal swap-and-inspection cycle that studs create. For drivers who want winter grip without the compliance calendar, studless is the simpler path.

Crossing Into Neighboring States

If you drive across state lines with studs on, the Massachusetts window is not the one that matters once you cross. Each neighboring state sets its own dates:

Connecticut: November 15 through April 30.
Rhode Island: November 1 through April 1.
New York: October 16 through May 1.
Vermont: no seasonal restriction.
New Hampshire: no seasonal restriction.

Two mismatches trip up Massachusetts drivers most often. Rhode Island’s season ends a month earlier, on April 1, so a legal Massachusetts setup in mid-April is illegal across the border. Connecticut does not start its season until November 15, so studs mounted for a Massachusetts commute in early November violate Connecticut law for the first two weeks. Trips north to Vermont or New Hampshire raise no seasonal issue.
