Maine's School Bus Law and the 15 MPH School Zone, Read From the Statutes
On Wednesday, August 26, 2026, Gorham buses roll before any other district in Greater Portland. Most of the region follows on August 31, and Yarmouth brings everyone in on September 1. From that first morning until late June, several hundred yellow buses stop on roads you drive every day, and a set of rules that has been dormant since mid-June is live again.
Almost everyone thinks they know these rules. Most people have some version that is close. The version that matters is the statutory one, and on three points the statute says something different from what drivers assume. Here is the whole set, read from the operative text at the Revisor of Statutes, with the parts people get wrong called out.
The trigger is the red lights, not the stop arm
This is the single most useful correction in this article, and it surprises nearly everyone.
29-A M.R.S. section 2308(2) says the operator of a vehicle "on a way, in a parking area or on school property, on meeting or overtaking a school bus from either direction when the bus has stopped with its red lights flashing to receive or discharge passengers, shall stop the vehicle before reaching the school bus."
Your duty attaches to the flashing red lights. It does not attach to the stop arm. And under section 2302(1)(G), a Maine school bus may be equipped with a system of stop arms. May. The stop arm is optional equipment in this state. What is mandatory is different and newer: section 2302(1-A) requires a school bus of model year 2021 or newer to carry a school bus crossing arm, the bar that swings out in front of the bumper to push kids away from the driver's blind spot. That is the front arm, not the side one.
So a bus with no stop arm, flashing red, obligates you exactly as much as a bus with one. If you are waiting to see a stop sign swing out before you commit to stopping, you are watching the wrong thing.
Two more details from the same neighborhood of the statute. Section 2308(1) requires the bus operator to activate the flashing lights at least 100 feet before the stop, which is your warning and is why a bus that lights up well ahead of its stop is following the rule rather than being indecisive. And section 2302(1)(G) says stop arms may be operated only with the red signal lights, so the arm and the reds always travel together.
Settle into Maine. Free.

The exception is narrower than drivers think
Section 2308(3) is the only exception, and it is written tightly. You need not stop if you are on a way "separated by curbing or other physical barrier" and the bus is in a lane on the other side of that barrier, or if you are on a limited access highway where pedestrians are not permitted to cross and the bus is stopped in a loading zone.
Read the operative words: curbing or other physical barrier. A painted centerline is not a barrier. A center turn lane is not a barrier. Four lanes of undivided road is not a barrier. On Forest Avenue, on Route 1 through Falmouth and Scarborough, on Brighton Avenue, the ordinary case is that traffic in both directions stops. Drivers who grew up in states with a wider oncoming-traffic exemption get this wrong constantly.
The other clause that catches people is the first one in subsection 2. The rule applies on a way, in a parking area, and on school property. The school pickup loop is covered. So is a shopping plaza lot where a bus stops.
It is a crime, not a ticket
Section 2308(6) makes a violation of subsection 2 a Class E crime, punishable by a $250 minimum fine for a first offense and a mandatory 30-day license suspension for a second offense within three years of the first.
Two things follow that most local summaries never state. First, Class E is a criminal classification, not a traffic infraction. Under 17-A M.R.S. section 1604(1)(E) the maximum term of imprisonment for a Class E crime is six months, and under 17-A M.R.S. section 1704(5) the maximum fine is $1,000. The $250 in the school bus statute is a floor, not a ceiling, and a conviction is a criminal conviction.
Second, the mandatory suspension is attached to the second offense inside three years, not the first. Plenty of pages imply you lose your license the first time. The statute does not say that.
The penalty was last amended by PL 2019, c. 318, and the amendment did something precise that is worth knowing: it changed "a violation of this section" to "a violation of subsection 2." Before 2019 the whole section carried the Class E label. Now only the failure to stop does.
You can be summonsed for a violation you did not commit
Section 2308(5) is the part of this law almost nobody has read, and it is the reason a bus driver writing down your plate matters.
A bus operator who sees a violation may report the time, the location, the plate number and a description of the vehicle to a law enforcement officer. The officer must open an investigation, contact the registered owner, and ask who was driving. The officer may then serve the registered owner with a summons. And subsection 5(C) says plainly that it is not a defense that the registered owner was not operating the vehicle.
That version of the offense is a traffic infraction rather than a Class E crime, which is the trade: a lower charge, but one that reaches the person whose name is on the registration. There are four listed defenses. Someone else is convicted of driving it. You are a leasing company and you hand over the lease. You are a dealer and you name who had the car. Or the vehicle had been reported stolen before the violation or within a reasonable time after.
If you lend your car to a teenager in September, that is the statute you are lending it under.
The school bus is one of only two places a traffic camera is legal in Maine
Maine bans automated traffic enforcement. 29-A M.R.S. section 2117 says the State or a municipality may not use a traffic surveillance camera to prove or enforce a violation of Title 29-A. There are no red light cameras and no speed cameras here, and that is a deliberate statewide policy.
The 2019 law carved out exactly two exceptions. One is Maine Turnpike toll enforcement. The other, in section 2117(1), is a camera mounted on a school bus, used with the lighted traffic control device, to prove or enforce a violation of section 2308(2).
The privacy terms are strict and worth knowing if you are the one photographed. The image or audio is confidential. It may be released only to a law enforcement officer for an investigation, or to an officer, prosecutor, defendant or court for a prosecution. And it may not be retained for more than 30 days from the date it was produced unless it is released under that subsection.
Yarmouth and Gorham both announced stop-arm camera programs in the fall of 2019, in the first season after the law took effect, and Scarborough has since added exterior cameras to buses. Whether a given district runs them today is a question for that district's transportation office. The law permits a camera. It does not require anyone to publish that they have one.
The 15 mph school zone, and the half hour nobody computes
Now the other half of the season, and this one is quietly stricter than drivers realize.
29-A M.R.S. section 2074(1)(A) sets a maximum of 15 miles per hour in a school zone in four circumstances, and they are alternatives, not conditions that must all be met:
- During recess.
- When children are going to or leaving school during school opening or closing hours, defined in the statute as one half hour before and one half hour after the beginning of the school day, and one half hour before and one half hour after the end of the school day.
- When school speed limit signs are flashing during opening or closing hours.
- At other times designated by a municipal traffic ordinance covering local town ways.
Point two is the one that matters. The 15 mph limit applies during that hour-wide window around each bell whether or not the beacon is flashing. A flashing sign is one of four triggers, not the definition of the zone. And a school zone during recess is a 15 mph zone in the middle of the day, which almost no driver has ever considered.
Working out the window in your town means knowing the bell times, and in Greater Portland that is harder than it sounds. Most districts here do not publish current start and dismissal times in any document you can open before Labor Day, which we went through district by district in what time school starts in Greater Portland. The first days themselves are spread across six calendar dates and are collected in our district-by-district school calendar guide.
The fine is doubled. Section 2074(3-B) sets the penalty for a school zone speeding violation at twice the ordinary fine for a similar excess of speed. And at 30 miles per hour or more over any limit, section 2074(3) makes speeding itself a Class E crime.
One structural point that explains why school zones are inconsistent from town to town: they are opt-in. Under section 2075(3)(F) a municipality may designate a school zone only with the approval of both the Department of Transportation and the Chief of the State Police, and in conformity with the federal Manual on Uniform Traffic Control Devices. There is no automatic school zone around every school building in Maine. Where one exists, a town asked for it and the State signed off.
While you are in the statute, note that 29-A M.R.S. section 2074(1)(C) and (D) were amended and paragraph E repealed by PL 2025, c. 199. Maine's default limits now read 25 miles per hour in a business or residential district or built-up portion, and 45 miles per hour on all other public ways, in both cases unless otherwise posted. Any local page still printing Maine's older default structure is out of date.
Crossing guards: only some of them can legally stop you
Section 2091-A, enacted in 2017, is short and almost unknown. A school crossing guard is qualified to direct traffic only if all five of these are true: the guard is 18 or older, is under the control of a local law enforcement agency, has completed traffic-control training approved by the Department of Labor's Bureau of Labor Standards, is wearing the uniform that agency specifies, and is directing traffic at an intersection with a marked crosswalk on a public way.
Disobeying a qualified guard's hand signal or handheld device is a traffic infraction. Subsection 3 allows an unqualified guard to help a pedestrian across, but not to direct traffic. And subsection 4 is the one to remember: a crossing guard may not contradict or override a lighted traffic control device. A guard cannot wave you through a red light, and if one does, the light still governs.
What actually changes on August 26
Nothing in this article is new law except the 2025 speed defaults. What is new is that on August 26 in Gorham, and August 31 across most of the region, the rules switch back on after ten weeks off, on roads where you have spent the summer driving without a bus in front of you.
The practical version is four sentences. Stop for flashing red lights from both directions unless there is actual curbing or a barrier between you. Assume 15 miles per hour near a school for the half hour on either side of the bells and during recess, flashing sign or not. Understand that the charge is criminal and that the registration in your glovebox is exposed even when you are not driving. And if you are new to Maine, this is one of several places where the rules here are stricter than the state you left, which is also true of Maine's winter driving laws and worth a look before October.
FAQ
When do you have to stop for a school bus in Maine?
You must stop whenever a school bus is stopped with its red lights flashing to receive or discharge passengers, from either direction, on a public way, in a parking area or on school property, under 29-A M.R.S. section 2308(2). You may not proceed until the bus resumes motion or the bus operator signals you to go. The trigger is the flashing red lights, not the stop arm, which Maine law makes optional equipment.
Do you have to stop for a school bus on a divided road in Maine?
No, but only if the road is separated by curbing or another physical barrier and the bus is in a lane on the other side of it, under 29-A M.R.S. section 2308(3). A painted centerline, a center turn lane, or simply having four undivided lanes does not qualify. The other exception is a limited access highway where pedestrians are not permitted to cross and the bus is in a loading zone.
What is the penalty for passing a stopped school bus in Maine?
Passing a stopped school bus in violation of 29-A M.R.S. section 2308(2) is a Class E crime with a $250 minimum fine for a first offense and a mandatory 30-day license suspension for a second offense within three years. Because it is a Class E crime, the statutory maximums are a $1,000 fine under 17-A M.R.S. section 1704(5) and six months of imprisonment under 17-A M.R.S. section 1604(1)(E).
What is the school zone speed limit in Maine?
Fifteen miles per hour, under 29-A M.R.S. section 2074(1)(A), during recess, during the half hour before and after both the start and the end of the school day, when school speed limit signs are flashing during those hours, or at other times set by municipal ordinance on local roads. The limit applies during the opening and closing window whether or not a sign is flashing, and section 2074(3-B) doubles the fine for violating it.
Can school buses in Maine have cameras that ticket drivers?
Yes. 29-A M.R.S. section 2117 bans traffic surveillance cameras in Maine with two exceptions, and one of them is a camera mounted on a school bus used to prove or enforce a violation of section 2308(2). The footage is confidential, may be released only to law enforcement, a prosecutor, a defendant or a court, and may not be retained more than 30 days unless it is released.
Can I be ticketed if someone else was driving my car past a school bus?
Yes. Under 29-A M.R.S. section 2308(5), a bus operator may report your plate to a law enforcement officer, who may then summons the registered owner, and subsection 5(C) states that it is not a defense that the owner was not driving. That version of the offense is a traffic infraction rather than a Class E crime. The listed defenses are that someone else is convicted of driving, that you are a lessor producing the lease, that you are a dealer naming the driver, or that the vehicle was reported stolen.
Do I have to obey a school crossing guard in Maine?
Only a qualified one, and 29-A M.R.S. section 2091-A sets five requirements: 18 or older, under the control of a local law enforcement agency, trained to a Bureau of Labor Standards approved standard, in the uniform that agency specifies, and directing traffic at an intersection with a marked crosswalk on a public way. Disobeying a qualified guard is a traffic infraction. No guard may contradict or override a lighted traffic signal.
