Massachusetts School Bus Law: When You Must Stop and the Fine

informational·how to guide·Published June 28, 2026

When must you stop for a school bus in Massachusetts?

Stop when a school bus, or a van or car with a SCHOOL BUS sign, stops with its red lights flashing to let pupils on or off. Make a full stop before you reach it, from either side of the road, and wait until the signals are off. The one exception: you approach from the opposite direction on a divided highway. A first violation costs at least $250.

Where the Massachusetts school bus rules come from

The stop rule, the 100-foot rule and the fines are in Massachusetts General Laws (M.G.L.) chapter 90, section 14. The plain-language version, with the vehicle descriptions and the penalty for a first violation, is in the School Buses part of the Massachusetts Driver's Manual (revised April 2026) from the Registry of Motor Vehicles (RMV). The PUPIL plate rule is in the RMV regulation 540 CMR 2.05. Where the law and the manual differ, this guide follows the law. This guide is current as of 2026. Confirm the rules with the Massachusetts RMV (mass.gov/rmv) before you drive.

Which vehicles count as a school bus in Massachusetts?

A yellow school bus has flashing red lights and a stop sign that folds out on the driver's side. Smaller school pupil transport vehicles, such as vans, station wagons and family sedans, have flashing red lights and a SCHOOL BUS sign on the roof. They also carry a PUPIL registration plate. Both types flash their red lights while pupils get on or off, and the stop rule covers both.

Do you stop? The divided highway exception

You approach the bus from the opposite direction on a divided highway

You do not have to stop. This is the one exception in the law. The Driver's Manual adds that a barrier separates the travel directions. Check yourself with the practice question on the school bus exception on a divided highway.

You approach on an undivided road, from the front or from behind

You must stop, even when the bus is on the other side of the road. The practice question on stopping for a flashing school bus on an undivided road tests this rule.

You travel in the same direction as the bus on a divided highway

You must stop. The exception covers only drivers who approach from the opposite direction.

How to stop for a school bus, step by step

1
Watch for the signals early
Look for the SCHOOL BUS sign, red lights that flash in turn at the front and rear, and, on a yellow bus, the stop sign that folds out from the driver's side.
2
Stop before you reach the bus
Come to a full stop before you reach the bus. Do not creep past it.
3
Stay stopped until the signals go off
Wait until the lights stop flashing or the stop sign folds back. Only a police officer who is authorized to control traffic can direct you to go sooner.
4
Drive on slowly
After the signals stop, move off slowly and keep looking for children.

How far behind a school bus must you stay?

No driver may operate a motor vehicle within 100 feet behind a school bus. Every school bus must show the words "keep back 100 feet" on its back, in letters large and dark enough to read from that distance. The practice question on the minimum distance behind a school bus has the same answer: 100 feet.

Massachusetts school bus fines and license penalties as of 2026

Massachusetts school bus fines and license penalties as of 2026

Third or later offense	$1,000 to $2,000	Revoked at once. No new license until 1 year after the revocation date.

Can an appeal stop a school bus license revocation?

No. After a second or later conviction, the court reports it to the registrar at once, and the registrar revokes your license or right to drive. An appeal, a motion for a new trial or exceptions do not stop the revocation. If the case ends in your favor, the registrar reinstates your license at once.

Massachusetts school bus law: common questions

Do I have to stop for a school bus on the other side of the road?

Yes, on a road with no divider. When the bus has its red lights flashing to let pupils on or off, drivers from both directions stop before they reach it. You may keep going only when you approach from the opposite direction on a divided highway.

How long do I wait at a stopped school bus?

Until the warning signals are off: the red lights stop flashing or the stop sign folds back. A police officer who is authorized to control traffic can wave you on sooner. When you move again, go slowly and keep looking for children.

What happens if I pass a stopped school bus in Massachusetts?

A first violation carries a fine of at least $250, and the Driver's Manual says it can also lead to a license suspension. A second offense costs $500 to $1,000, and the registrar revokes your license for at least 6 months. A third or later offense costs $1,000 to $2,000, with a revocation of at least 1 year.

Does the school bus law apply to vans and cars?

Yes, when the vehicle is a school pupil transport vehicle. These vans, station wagons and family sedans have flashing red lights and a SCHOOL BUS sign on top, and they carry a PUPIL registration plate. When their red lights flash to let pupils on or off, stop as you would for a yellow bus.
