Passing on the right in Massachusetts is legal, but only in three narrow situations spelled out by Mass. Gen. Laws ch. 89, § 2: when the vehicle ahead is turning left, when you are on a one-way street, or when you are on a road where all traffic moves in the same direction and there is room for two lines of vehicles. Outside those situations, the default rule holds and you must overtake on the left.
The Three Situations Where It Is Allowed
Each of the three exceptions carries the same baseline requirement: the road has to be clear of obstructions and wide enough for at least two lines of moving traffic.
- The car ahead is making or about to make a left turn. This is the most common and least controversial situation.
- You are on a one-way street, where there is no oncoming traffic to create a head-on risk.
- You are on a road restricted to one direction of travel, such as a divided highway or a multi-lane road where every lane flows the same way. If the vehicle ahead sits in the left lane, moving past in the right lane is legal.
In all three cases you have to stay within a marked travel lane. The statute does not authorize driving onto the shoulder, into a bike lane, or onto an unpaved surface to get around another car.
Where You Cannot Pass on the Right
If none of the three exceptions apply, right-side passing is illegal. On a standard two-lane road where the car ahead is not turning left, you cannot swing right to overtake. A few specific places catch drivers out.
Breakdown Lanes and Shoulders
Under ch. 89, § 4B, when the right lane has been built or marked for a purpose other than ordinary travel, you have to use the adjacent lane instead. The breakdown lane on a highway is there for emergencies and disabled vehicles. Using it to slip past traffic is a separate violation stacked on top of the improper passing, unless signs specifically permit travel in that lane during certain hours.
Bike Lanes
Bike lanes work the same way. They are designated for cyclists, and a motor vehicle that drives in one to bypass slower traffic breaks both the lane-use rule and the passing rule.
The Fine for an Improper Passing Ticket
A violation of ch. 89, § 2 is a civil motor vehicle infraction, not a criminal offense. The fine is $100 plus a $5 public safety surcharge, for a total of $105. Ignore the ticket for more than 20 days and late fees and release fees start piling on.
What It Does to Your Insurance
The bigger financial hit usually comes through your premium. Massachusetts uses the Safe Driver Insurance Plan to adjust rates based on your driving record, and an improper-passing citation is classified as a minor traffic law violation worth 2 surcharge points. Those points affect your rates over a six-year policy experience period, though incidents in the sixth year do not themselves generate surcharge points.
The SDIP does not set a fixed percentage increase per point. Each insurer applies its own surcharge factor based on your total point count, so the dollar impact varies. A 2-point minor violation can noticeably raise your annual premium, and the effect compounds if you already have incidents on your record. The Massachusetts Division of Insurance directs drivers to check with their own insurer for a specific figure.
If enough points pile up that no voluntary-market insurer will write you a policy, you land in the Massachusetts Automobile Insurance Plan. MAIP is the state’s involuntary market for high-risk drivers, and premiums there run substantially higher than a standard policy.
When It Becomes a Criminal Charge
A routine improper-passing ticket stays civil. But if the way you passed on the right endangered other people, an officer can charge you with negligent or reckless operation under ch. 90, § 24(2)(a). That shifts the case from a citation to a criminal misdemeanor.
The penalties are much steeper than $105:
- A fine of $20 to $200, plus a mandatory $250 assessment the court cannot waive or reduce.
- Jail time from two weeks to two years.
- License revocation on conviction, unless the court specifically recommends otherwise. For a first offense, you are ineligible for reinstatement for at least 60 days.
Officers weigh the circumstances when deciding whether to upgrade the charge: your speed, how close you came to other vehicles, whether you forced anyone to swerve, and whether the maneuver caused a crash. Weaving across the shoulder at highway speed to pass three cars is a different situation from easing past a left-turning vehicle on a wide street.
Accumulating Violations and Losing Your License
Even without a reckless driving charge, stacking traffic violations over time can cost you your license. Under ch. 90, § 22F, the RMV classifies you as a habitual traffic offender and suspends your license for four years if, within a five-year period, you accumulate either three convictions for serious offenses (such as reckless driving, operating under the influence, or leaving the scene of an accident) or twelve convictions for any combination of reportable moving violations.
An improper-passing citation by itself will not trigger this, but it counts toward the twelve-violation total. If you already have a few infractions on your record, a minor ticket may be the one that tips the scale.
Contesting the Citation
You have 20 days from the date of the citation to either pay the fine or request a hearing. Miss that deadline and you waive the hearing and trigger late fees.
Clerk-Magistrate Hearing
The first appeal level is a hearing before a clerk-magistrate at the district court where the infraction occurred, with a $25 scheduling fee. A police prosecutor reads from the citing officer’s report, and then you present your side. Dashcam footage, photos of the road layout, and witness statements all help. The clerk-magistrate can find you not responsible, uphold the citation, or reduce the fine.
Appeal to a Judge
If the clerk-magistrate rules against you, you can appeal to a judge for a $50 fee. The hearing is more formal, and one detail works in your favor: the officer who wrote the ticket must appear in person. If the officer does not show up, the judge enters a finding of not responsible without holding a hearing. That alone makes the judge-level appeal worth considering when you believe the citation was unfair.
For a straightforward improper-passing ticket, most drivers handle the process themselves. If the citation is tied to an accident, paired with a reckless driving charge, or comes when you are close to the habitual-offender threshold, a traffic attorney can identify procedural problems, challenge the officer’s account, or negotiate for an outcome that keeps the violation off your SDIP record.
