The Massachusetts Move Over Law requires you to slow down whenever you approach a stationary vehicle on the roadside displaying flashing lights, and to change lanes away from it when you are on a highway with at least four lanes and can move over safely. The rule is codified at MGL c. 89, ยง 7C. Violations start at a $100 maximum fine and climb to $500 for repeat offenders, with insurance consequences that usually cost more than the ticket.
Which Stopped Vehicles You Must Move Over For
The statute covers three original categories. Emergency response vehicles include police cruisers, fire apparatus, ambulances, and disaster vehicles. Highway maintenance vehicles are those used by state or local government, or their contractors, to maintain roads. Recovery vehicles are those designed to assist or tow disabled vehicles.
The color of the flashing light does not matter. The statute says “flashing lights” without specifying blue, red, or amber. If a stationary vehicle on the shoulder falls into a covered category and is displaying any flashing lights, the law applies.
A recent expansion added two more situations. You must also move over or slow down for disabled vehicles displaying hazard lights on the shoulder or breakdown lane, and for utility worker vehicles, including telecom, electric, and gas crews working roadside with flashing lights on.
What the Law Requires You To Do
Every driver approaching a covered stationary vehicle must slow down and proceed with caution. That baseline applies on every road. On a highway with at least four lanes and at least two lanes running in your direction, you also have to change lanes away from the stopped vehicle when you can do it safely.
The statute frames this as a two-part duty: reduce speed to what is “reasonable and safe for road conditions,” and move into a non-adjacent lane if the road layout allows. The chosen speed must be below the posted limit, not just slightly under the flow of traffic. Swerving into the next lane at full speed does not satisfy the rule; both parts work together.
When You Cannot Change Lanes
If traffic is heavy, conditions are poor, or the highway does not have enough lanes, the law does not force a lane change. The statute uses the phrase “if practicable,” meaning you move over only when you can do it without creating a new danger. In that case, slowing to a reasonable and safe speed and passing with caution is enough.
On a two-lane road with one lane in each direction, a lane change is never possible, so the slow-down obligation carries the full weight. Give as much space as the road allows without crossing into oncoming traffic, and pass at a speed that would let you stop quickly if a worker stepped into your path.
Fines for a First Offense
A first violation carries a fine of up to $100. That figure is a maximum, not a fixed amount, so a court may impose less depending on the circumstances.
Penalties for Repeat Violations
Repeat offenses climb sharply. A second violation raises the maximum fine to $250 and requires the driver to complete a driver education program. A third or subsequent violation carries a fine of up to $500. The mandatory education requirement for a second offense is unusual for a Massachusetts traffic infraction, most of which do not carry any classroom component.
Insurance and Driving Record Consequences
A Move Over Law violation is a moving violation, and it can affect your insurance rates through the Massachusetts Safe Driver Insurance Plan. The SDIP assigns points to traffic offenses and at-fault accidents: minor traffic violations carry two points, and major criminal traffic offenses carry five. Surchargeable offenses are listed in Appendix A of the SDIP regulation, and a violation on that list triggers a premium surcharge once you pay the fine or are found responsible.
The surcharge often costs more than the fine. A two-point surcharge can add several hundred dollars a year to your premium and typically stays on your record for multiple policy years. Over three to six years, that can total well over $1,000, dwarfing the $100 first-offense maximum.
If Someone Is Hurt
The Move Over Law itself does not include enhanced penalties for violations that cause injury or death. The fine schedule is the same whether or not anyone is harmed. A driver who strikes a roadside worker or responder can still face separate criminal charges under other provisions of Massachusetts law, such as negligent operation of a motor vehicle or, in the worst cases, motor vehicle homicide. A Move Over Law violation in the same incident would be strong evidence of negligence in both a criminal case and any civil suit that follows.
Practical Tips for Compliance
Spotting flashing lights early is the whole game. Scan well ahead on highways so you have time to check your mirrors and merge smoothly instead of braking hard at the last moment. If you are in the right lane and see lights on the right shoulder, start looking for a gap in the middle lane right away. Waiting until you are alongside the stopped vehicle forces a panicked swerve and defeats the point of the rule.
When slowing is your only option, lift off the gas well before you reach the scene and coast down to a noticeably lower speed. The statute requires a speed below the posted limit; on a highway, dropping 15 to 20 miles per hour under the limit is a reasonable starting point. On surface streets posted at 30 or 35, slowing to 15 or 20 gives roadside workers a much wider margin of safety.
