Massachusetts Studded Tires: Legal November 1 Through April 30

The studded tire rule sits in the last paragraph of G.L. c. 90, § 16, a section otherwise devoted to mufflers, exhaust modifications, horns, sirens and spot lights. Nothing in the paragraph asks a Massachusetts driver to obtain anything before mounting studs. There is no seasonal permit, no fee, no notice to the Registry and no marking on the registration. The driver simply must not have metal studded tires on the vehicle while it is operated on a public way during the closed period, which runs from May 1 to November 1.

Read the closed window carefully, because it does the work in both directions. Studs may go on at the start of November and may stay on through the whole of the winter and all of April. May 1 is the day they must be off. A vehicle sitting in a driveway on studs in June breaks nothing, since the prohibition reaches operation on a public way, not possession or mounting.

The Registrar has an express early-start power and no matching late-finish power. Section 16 says the Registrar may authorize the use of such tires before November 1 if weather conditions require, so an early November snowfall pattern can pull the opening date forward by administrative action. There is no parallel sentence letting the Registrar extend studs past May 1 for a late storm, so the closing date is the harder of the two.

The exemption list is one item long: a duly authorized person driving an emergency fire vehicle. Massachusetts did not carve out police cruisers, ambulances, municipal plows or utility trucks from this paragraph, which is striking next to the exemption list elsewhere in section 16, where fire apparatus, ambulances, vehicles used in the official line of duty by police or fire forces, and vehicles owned by call firefighters are all separately named in the siren rule three paragraphs earlier. The drafter knew how to write a broader list and did not write one here.

Massachusetts also carries two different penalty figures for the same conduct, and both are in force. The studded tire paragraph itself says a violator shall be punished by a fine of not more than fifty dollars. The chapter's general penalty section, G.L. c. 90, § 20, separately provides that any person convicted of violating any of the provisions of section sixteen shall be punished by a fine of not less than twenty nor more than one hundred dollars. The paragraph-specific fine is the narrower of the two and is the one written into the studded tire rule, but a reader should know the chapter-wide figure exists and reaches section 16 violations by its own terms.

Section 20 adds a consequence that has nothing to do with money. On a third or subsequent conviction within the same twelve-month period of a violation of section 16, the Registrar shall forthwith revoke the license of the person convicted, and no new license may issue for at least thirty days after the revocation, and thereafter only in the Registrar's discretion. A studded tire offence is a section 16 offence, so it counts toward that tally alongside the muffler, exhaust and excessive noise offences in the same section.

Separately from the seasonal rule, Massachusetts regulates the tires themselves. Chapter 90 carries minimum tire safety standards with their own penalty, a quality marking requirement for retread and recapped tires offered for sale, and tread depth regulations under which operation of a non-complying vehicle is prohibited. Being inside the November to April window answers the seasonal question only, not whether the tire is otherwise legal to run.

c. 90, § 16, enforced by police in the ordinary way through the District Court or the Boston Municipal Court. The fine written into the studded tire paragraph is not more than fifty dollars. c. 90, § 20 states a wider band of not less than twenty nor more than one hundred dollars for any section 16 violation, so the two provisions disagree on the ceiling and the paragraph-specific figure is the narrower one. The heavier exposure is licence loss: under § 20, a third or subsequent conviction of a section 16 violation within the same twelve-month period requires the Registrar to revoke the offender's licence forthwith, with no new licence for at least thirty days and reinstatement after that only at the Registrar's discretion.

Because the ban is written as an operating offence, the citation follows the driver, and unlike the muffler and prohibited-way paragraphs at the top of section 16, this paragraph does not separately reach an owner who permitted the operation.
