The Stop Arm on Two Different Roads
Derek, 17, holds a Maine intermediate license and drives himself to school. In the morning he travels east on Route 202, a two-lane road with a painted center turn lane for the school entrance. At 7:40 a.m. a school bus ahead of him in his own lane stops, its red lights begin flashing, and the stop arm swings out. Derek is about 60 feet back in the through lane, and the driver behind him is following closely. That afternoon, on the way home, he takes a divided four-lane highway with a raised median; a school bus on the opposite side of the median stops with red lights flashing to unload students. Derek has seen drivers in both directions handle these situations very differently, and his passenger tells him he only ever has to stop when the bus is in his own lane.
1. What must Derek do in the morning situation on Route 202?
Read the worked answer
He must stop and stay stopped.
The bus is in his lane and traveling in his direction, with red lights flashing and the stop arm out. Maine requires traffic approaching from either direction to stop for a school bus displaying red lights, and to remain stopped until the red lights stop flashing.
Distance matters: Maine measures the required stop as at least 15 feet from the bus, which gives children room to cross in front of it. Derek is 60 feet back, so he has time to slow gradually rather than brake hard.
The tailgater does not change the legal duty. Derek should brake early and smoothly so the following driver has warning, and he should not wave children across or creep forward while the arm is out. The painted center turn lane does not make this a divided highway - it is still a two-lane road for stop-arm purposes, so the rule applies in both directions.
2. What is required in the afternoon situation on the divided highway with the raised median?
Read the worked answer
Derek does not have to stop for that bus - but the exception is narrow.
The stop-arm rule applies to traffic approaching the bus, but Maine carves out an exception when the opposing lanes are separated by a physical median or barrier. On a divided highway with a raised median, traffic on the far side is not required to stop for a bus serving the other side.
The reasoning: children unloading on that side are not expected to cross a raised median and four lanes of traffic to reach Derek's direction, so stopping him would create a rear-end hazard for no safety benefit.
What does not qualify: a painted center turn lane, a two-way left-turn lane, or a simple double yellow line. Those are paint, not a barrier, and the stop is required. Derek should also stay alert - kids sometimes cross anyway - but the legal duty to stop is not triggered here.
3. Derek's passenger says he only has to stop when the bus is in his own lane. Evaluate that claim.

The claim is wrong, and it is the kind of wrong that produces stop-arm violations.
The test is not "is the bus in my lane?" It is:
- Is the bus displaying red flashing lights (not yellow)?
- Am I approaching it on an undivided roadway, or a roadway without a physical median separating my direction from the bus?
On an ordinary two-lane road, a bus on the opposite side with red lights requires traffic in both directions to stop. A driver who believes the passenger's version would pass a stopped bus on a two-lane road and commit a serious violation, with children possibly crossing.
Yellow lights are the warning phase; red lights plus the stop arm are the stop signal. If Derek is ever unsure whether a median counts, the safe and legally defensible choice is to stop.
