What Is the Move Over Law in Massachusetts?

The Massachusetts move over law is M.G.L. c. 89, sec. 7C, and it requires that when you approach a stationary emergency response vehicle, highway maintenance vehicle or recovery vehicle that has its lights flashing, you slow to a speed that is reasonable and safe for the conditions, and, if it is practicable and the road has at least four lanes with at least two running in your direction, you move out of the lane next to that vehicle. If changing lanes is not practicable, the duty does not disappear: you still have to proceed with due caution and reduce your speed. A violation carries a fine of not more than $100. That small fine is the least important part of the statute, because what a move over violation really does is hand the other side a piece of evidence in any injury claim that follows. This article explains what the section covers, the one common roadside situation it does not cover, how it differs from the separate rule about emergency vehicles that are moving toward you, and what it means for a claim if someone was hurt.

What the Statute Actually Says

Section 7C is short, and it is worth reading in the words the Legislature used rather than in the words of a driver education slide.

Subsection (b) sets the duty: “Upon approaching a stationary emergency vehicle, highway maintenance vehicle or recovery vehicle with flashing lights an operator shall: (1) proceed with due caution, reduce the speed of the vehicle to that of a reasonable and safe speed for road conditions, and, if practicable and on a highway having at least 4 lanes with not less than 2 lanes proceeding in the same direction as the operator’s vehicle, yield the right-of-way by making a lane change into a lane not adjacent to that of the emergency response vehicle, highway maintenance vehicle or recovery vehicle; or (2) if changing lanes is impracticable, proceed with due caution and reduce the speed of the vehicle to that of a reasonable and safe speed for road conditions.”

Subsection (c) sets the penalty: “Violation of this section shall be punished by a fine of not more than $100.”

Three things follow from that text, and each of them surprises somebody.

The slowing duty is unconditional. It applies whether or not you can change lanes, whether or not the road has four lanes, and whether or not there is anyone behind you. The lane change is the conditional part.

There is no fixed number in the statute. Some states write a specific speed into their move over law, such as twenty miles per hour below the posted limit. Massachusetts did not. What section 7C requires is “a reasonable and safe speed for road conditions”, which is a judgment call assessed after the fact, by an officer at the scene or by a jury in a courtroom.

The statute says nothing about licence points, surcharges or insurance. People often assume a move over ticket carries an automatic insurance consequence. Whatever an insurer does with a citation is a matter of the policy and the rules that govern it, not of section 7C, which contains a fine and nothing else.

The Three Vehicles It Covers, and the One It Does Not

Subsection (a) defines the vehicles, and the definitions are narrower than most drivers assume.

An “emergency response vehicle” is “a fire apparatus, police vehicle, ambulance, or disaster vehicle”. That is the whole list.

A “highway maintenance vehicle” is “a vehicle used for the maintenance of highways and roadways” that is either owned or operated by the state transportation agency, a county, a municipality or a political subdivision, or owned or operated by someone under contract with one of those bodies. The contractor clause matters. A private paving company working a state or municipal contract is inside the definition; the same company’s truck on a private driveway job is not.

A “recovery vehicle” is “a vehicle that is specifically designed to assist a disabled vehicle or to tow a disabled vehicle”. A tow truck and a roadside assistance service truck are recovery vehicles. A friend’s pickup is not, however good the intention.

Now the gap. An ordinary passenger car pulled onto the shoulder with its hazard lights on is not an emergency response vehicle, not a highway maintenance vehicle and not a recovery vehicle. Section 7C simply does not reach it. Drivers hear “move over for flashing lights” and generalise the rule to every set of hazards in the breakdown lane, and the generalisation is good practice, but it is not this statute.

That does not mean you may pass a broken down car at speed with impunity. M.G.L. c. 90, sec. 17 says no person “shall run it at a rate of speed greater than is reasonable and proper, having regard to traffic and the use of the way and the safety of the public”, and it adds that regardless of any posted limit, “every person operating a motor vehicle shall decrease the speed of the same when a special hazard exists”. A person standing beside a disabled car on a highway shoulder is a special hazard. The duty is there. It just comes from a different section, and it is written as a general standard rather than as a specific lane change.

Answer Capsule

The Massachusetts move over law is M.G.L. c. 89, sec. 7C. On approaching a stationary emergency response vehicle, highway maintenance vehicle or recovery vehicle with flashing lights, a driver must proceed with due caution and reduce speed to a reasonable and safe speed for road conditions, and must change out of the adjacent lane if that is practicable and the highway has at least four lanes with at least two running in the driver’s direction. If changing lanes is impracticable, the driver must still proceed with due caution and reduce speed. The statute defines an emergency response vehicle as a fire apparatus, police vehicle, ambulance or disaster vehicle; a highway maintenance vehicle as one owned or operated by the state transportation agency, a county, a municipality or a political subdivision, or by a contractor to one of them; and a recovery vehicle as one specifically designed to assist or tow a disabled vehicle. An ordinary disabled car with hazard lights is outside all three definitions, although M.G.L. c. 90, sec. 17 still requires a driver to decrease speed when a special hazard exists. The penalty under section 7C is a fine of not more than $100, and the section contains no points, surcharge or licence provision. Section 7C is a different rule from M.G.L. c. 89, sec. 7A, which governs emergency vehicles approaching you and requires drivers to pull as far as possible toward the right-hand curb and stand still until the vehicle has passed. In an injury case, M.G.L. c. 231, sec. 85 makes the violation of a statute evidence of negligence rather than an automatic loss, damages are reduced in proportion to fault, and an injured person is presumed to have been in the exercise of due care. The general deadline for a tort claim is three years under M.G.L. c. 260, sec. 2A. This is general information and not legal advice.

The Four Lane Condition Most Drivers Miss

Read subsection (b)(1) again and notice how many conditions must be satisfied before the lane change becomes mandatory. It must be practicable. The highway must have at least four lanes. At least two of them must run in the same direction as you. Only then are you required to yield the right of way by moving into a lane that is not adjacent to the stopped vehicle.

That is a description of a highway, and much of the road network in Massachusetts is not one. On a two lane state road through a small town, on most municipal streets, and on many rural stretches in the western part of the state, the four lane condition is never met, and paragraph (2) is the operative rule: due caution, reduced speed, no lane change required.

The word “practicable” carries weight even on a qualifying highway. Traffic in the next lane, a solid line of vehicles beside you, ice, a merge already in progress: any of these can make a lane change the wrong move, and the statute anticipates that by giving paragraph (2) as the alternative rather than as an excuse. What the statute never permits is doing neither. A driver who neither moved nor slowed has not complied under either paragraph.

There is a practical consequence worth stating plainly. Swerving abruptly into a lane you did not check, in order to comply with a statute, can create the exact collision the statute exists to prevent. Section 7C asks for a lane change only when it is practicable, and a lane change into occupied space is not practicable. Slow down first. That part of the duty is never conditional.

Move Over and Pull Over Are Two Different Statutes

Massachusetts has two separate rules about emergency vehicles, and confusing them is common enough to be worth separating carefully.

Section 7C, the move over law, is about a vehicle that is stationary. It is already stopped on or beside the road with its lights going, and you are coming up on it. The duty is to slow, and to leave an empty lane between you and it where that is practicable.

M.G.L. c. 89, sec. 7A is about a vehicle that is moving toward you or coming up behind you. It reads: “Upon the approach of any fire apparatus, police vehicle, ambulance or disaster vehicle which is going to a fire or responding to call, alarm or emergency situation, every person driving a vehicle on a way shall immediately drive said vehicle as far as possible toward the right-hand curb or side of said way and shall keep the same at a standstill until such fire apparatus, police vehicle, ambulance or disaster vehicle has passed.” That is a stop, not a slow. Section 7A also prohibits driving over a fire department hose without consent, driving within three hundred feet of fire apparatus going to a fire or responding to an alarm, and parking or leaving a vehicle unattended within eight hundred feet of a fire or in established fire lanes in a way that obstructs the approach of emergency vehicles.

Behind both sits M.G.L. c. 89, sec. 7, which gives fire apparatus responding to an alarm, police patrol vehicles and ambulances the right of way “through any street, way, lane or alley”, and which punishes anyone who “wilfully obstructs or retards” their passage with a fine of fifty dollars or imprisonment for not more than three months for a first offence, not more than five hundred dollars or up to a year for later offences, and on a third or subsequent offence a possible licence suspension and mandatory classroom retraining ordered by the court or the Registry.

Set those side by side and the penalty structure tells you what the Legislature was weighing. Wilfully blocking an ambulance can reach a licence. Failing to change lanes past a stopped cruiser reaches at most a hundred dollars. Section 7C was written as a safety norm, not as a punishment.

What a Move Over Violation Does to an Injury Claim

This is where the hundred dollar fine stops being the point.

Massachusetts does not treat the violation of a safety statute as automatic liability. M.G.L. c. 231, sec. 85 says so directly, in the context of an injured person’s own conduct: “The violation of a criminal statute, ordinance or regulation by a plaintiff which contributed to said injury, death or damage, shall be considered as evidence of negligence of that plaintiff, but the violation of said statute, ordinance or regulation shall not as a matter of law and for that reason alone, serve to bar a plaintiff from recovery.”

Evidence of negligence. Not proof of it, and not an automatic bar. The same principle runs the other way when the person who broke the rule is the defendant: the violation goes to the jury as evidence, and the jury decides what it is worth alongside everything else in the case.

Section 85 then sets the comparative fault rule that decides the money. Contributory negligence does not bar recovery so long as the injured person’s share of the negligence “was not greater than the total amount of negligence attributable to the person or persons against whom recovery is sought”, and any damages awarded are “diminished in proportion” to that share. It also places the burden of proving the injured person’s negligence on the party asserting it, and states that “the plaintiff shall be presumed to have been in the exercise of due care”. How that arithmetic works in practice is covered in the article on comparative negligence and partial fault, and the evidence side of it in how fault is determined after a Massachusetts car accident.

The practical shape of a move over case, then, is this. The citation, if one issued, is a document the other side will want. The absence of a citation does not end the argument either, because the standard in the statute is behaviour, not paperwork: what matters is whether the driver proceeded with due caution and reduced speed to what was reasonable and safe for the conditions. That gets proved with the crash report, the scene photographs, the position of the vehicles, dashcam or cruiser video where it exists, and the accounts of the people who were standing there. The mechanics of getting the report itself are in how to report a car accident in Massachusetts.

It is also worth knowing how this interacts with an ordinary speeding allegation, since the two travel together in roadside cases. Whether exceeding a limit is a crime, an infraction, or simply prima facie evidence of an unreasonable speed is the subject of is speeding a crime in Massachusetts, and the same distinction between a rule of the road and proof of fault applies to the phone rules discussed in the article on the Massachusetts hands free driving law.

If You Were the One Standing on the Shoulder

The people section 7C protects are, by definition, at work: police officers, firefighters, paramedics, state and municipal road crews, contractors on a public works contract, and tow and roadside assistance operators. When one of them is struck, two separate systems usually open at once.

The first is workers compensation, which under M.G.L. c. 152 generally pays for medical treatment and a portion of lost wages regardless of who was at fault, and which generally cannot be used to sue the employer. How that system runs is covered in how long workers comp lasts in Massachusetts and in workers comp attorney fees. Whether an injury on the way to or from a job site is covered at all is the subject of the going and coming rule.

The second is an ordinary negligence claim against the driver who caused the collision, which is a separate case against a separate party, and which can reach categories of loss that workers compensation does not pay, including pain and suffering. Roadside work raises the same questions as the ones in construction site injury claims in Massachusetts, and the coverage questions it raises are those in uninsured and underinsured motorist coverage.

If the vehicle that struck the worker belonged to a public body, the claim runs into a different and much shorter set of deadlines than the ordinary three year clock. That is the subject of whether you can sue the state or a city in Massachusetts, and it is the reason a roadside case should not be left to sit.

The Deadlines

For an ordinary negligence claim against another driver, M.G.L. c. 260, sec. 2A applies: “actions of tort, actions of contract to recover for personal injuries, and actions of replevin, shall be commenced only within three years next after the cause of action accrues.” The fuller picture, including the situations where the clock starts later than the crash date, is in the article on the statute of limitations for personal injury in Massachusetts.

If a public employer is involved, whether because a state or municipal vehicle was in the collision or because a public employee’s conduct is part of the claim, presentment and suit deadlines under M.G.L. c. 258 run at the same time and are shorter. Two clocks can run from a single crash, and the shorter one does not wait for anyone to notice it.

What Section 7C Does Not Decide

It does not decide fault. A driver can comply with section 7C perfectly and still be at fault for a crash on other grounds, and a driver can violate it and still not be the cause of a particular collision.

It does not set a speed. Anyone who tells you the Massachusetts move over law requires a specific number of miles per hour below the limit is describing another state’s statute.

It does not cover every roadside emergency. The three defined categories are the three defined categories, and the ordinary disabled car sits outside them.

It does not create a claim by itself. Section 7C is a rule of the road with a fine attached. An injury claim comes from injury, causation and damages, proved with evidence, and the statute is one piece of that proof rather than a substitute for it.

Frequently Asked Questions

Q: What is the fine for violating the move over law in Massachusetts?

A: Not more than $100. M.G.L. c. 89, sec. 7C, subsection (c) reads in full: “Violation of this section shall be punished by a fine of not more than $100.” The section says nothing about licence points, surcharges, retraining or suspension. That is a deliberate contrast with M.G.L. c. 89, sec. 7, which covers wilfully obstructing or retarding an emergency vehicle exercising its right of way, and which does carry escalating fines, possible imprisonment, and on a third or subsequent offence a possible licence suspension and mandatory classroom retraining.

Q: Do I have to change lanes for a tow truck in Massachusetts?

A: A tow truck is inside the statute. Section 7C defines a “recovery vehicle” as “a vehicle that is specifically designed to assist a disabled vehicle or to tow a disabled vehicle”, and lists recovery vehicles alongside emergency response vehicles and highway maintenance vehicles. So if a tow truck is stationary with its lights flashing, the duty applies: slow to a reasonable and safe speed for the conditions, and move out of the adjacent lane if that is practicable and the road has at least four lanes with at least two running your way. On a two lane road, slowing is the whole of the duty.

Q: Does the move over law apply to a broken down car with its hazard lights on?

A: Not by its terms. The three categories in subsection (a) are emergency response vehicles, meaning a fire apparatus, police vehicle, ambulance or disaster vehicle; highway maintenance vehicles owned or operated by a public body or its contractor; and recovery vehicles designed to assist or tow. A private car on the shoulder is none of those. A separate duty still applies under M.G.L. c. 90, sec. 17, which forbids a speed “greater than is reasonable and proper, having regard to traffic and the use of the way and the safety of the public” and requires a driver to decrease speed “when a special hazard exists”. Someone standing beside a stopped car on a highway shoulder is a special hazard, so slowing and giving room is the safe course as well as the lawful one.

Q: What if I cannot change lanes safely?

A: The statute answers that in subsection (b)(2): “if changing lanes is impracticable, proceed with due caution and reduce the speed of the vehicle to that of a reasonable and safe speed for road conditions.” The lane change is conditional on being practicable and on the road having at least four lanes with at least two in your direction. The slowing is not conditional on anything. A lane change into occupied space is not practicable, and forcing one can create the collision the statute is meant to prevent.

Q: How is the Massachusetts move over law different from pulling over for an ambulance?

A: They are two statutes about two different situations. Section 7C is about a vehicle that is already stopped with its lights on as you approach it, and asks you to slow and, where practicable on a four lane road, leave an empty lane. M.G.L. c. 89, sec. 7A is about a fire apparatus, police vehicle, ambulance or disaster vehicle approaching while responding to a call, alarm or emergency, and it requires every driver to “immediately drive said vehicle as far as possible toward the right-hand curb or side of said way” and to keep it “at a standstill until such fire apparatus, police vehicle, ambulance or disaster vehicle has passed”. One is slow down and move over. The other is pull right and stop.

Q: If a driver got a move over ticket, does that mean they are automatically liable for my injuries?

A: No. Massachusetts treats the violation of a statute as evidence of negligence rather than as automatic liability. M.G.L. c. 231, sec. 85 says a statutory violation “shall be considered as evidence of negligence” but “shall not as a matter of law and for that reason alone” decide the outcome. The citation is useful evidence and it is not the case. Fault still has to be proved from the crash report, the scene, the vehicle positions, any video, and the accounts of the people present, and damages have to be proved from the medical records.

Q: I am a tow operator and I was hit while working. What claims can exist?

A: Two systems commonly run at the same time. Workers compensation under M.G.L. c. 152 generally covers medical treatment and part of lost wages without regard to fault, and generally cannot be used to sue the employer. Separately, a negligence claim can be brought against the driver who caused the collision, and that claim can reach losses workers compensation does not pay. If a public body’s vehicle was involved, shorter presentment deadlines under M.G.L. c. 258 apply on top of the ordinary three year period in M.G.L. c. 260, sec. 2A. Which combination applies depends on the facts, and the timing questions are the ones worth raising early.

Q: Does the move over law apply on a two lane road?

A: The slowing duty does. The lane change duty does not, because subsection (b)(1) makes it conditional on the road “having at least 4 lanes with not less than 2 lanes proceeding in the same direction as the operator’s vehicle”. A great many Massachusetts roads never meet that condition, including most municipal streets and much of the two lane state road network, so on those roads paragraph (2) governs: proceed with due caution and reduce speed to what is reasonable and safe for the conditions.

Q: Is Jimmy Knows AI giving me legal advice?

A: No. This is general information about Massachusetts law, not legal advice, and reading it does not create an attorney-client relationship. Statutes are quoted as they read on malegislature.gov, but whether a particular section applies to a particular crash, and what a particular claim is worth, depend on facts this article cannot know.

Talking to a Lawyer

Most move over questions arrive after something has already happened. Either a driver has a citation and wants to know how much trouble it is, or someone who was standing on a shoulder has been hurt and wants to know what the rule was supposed to protect them from.

For the first, the honest answer is that the fine is capped at $100 and the statute contains nothing else, and that the citation matters most as evidence if a collision came with it.

For the second, the answer is that section 7C is worth knowing about but it is rarely the whole case. What decides a roadside injury claim is the evidence of the collision, the medical record, and which insurance policies and which deadlines are in play. Roadside cases are unusually likely to involve an employer, a public body, or both, and that is exactly where the short deadlines live.
