When do you have to stop for a school bus? In every state, you must stop when a school bus has its red lights flashing and its stop arm out, if you are behind it or on an undivided road. Whether oncoming traffic on a divided highway must stop depends on the state. This guide explains the lights, where to stop, the divided-highway rule and when you can move again.
Key facts
- Flashing yellow (amber) lights: the bus is preparing to stop. Slow down and get ready to stop.
- Flashing red lights and an extended stop arm: the bus has stopped. You must stop.
- NHTSA: every state bans passing a stopped school bus from behind. All states also ban passing from the front in at least some situations, such as on an undivided road.
- Divided highways: the rule for oncoming traffic varies. Some states let traffic on the far side of a median keep going, but New York requires you to stop even on the opposite side of a divided highway.
- Stay stopped until the red lights stop flashing, the stop arm is withdrawn and the bus starts moving (NHTSA).
What the school bus lights mean
| Bus signal | Meaning | What you do |
|---|---|---|
| Flashing yellow (amber) | Bus is about to stop | Slow down and prepare to stop. Do not speed up to get past. |
| Flashing red + stop arm out | Bus has stopped; children are getting on or off | Stop and stay stopped |
| Red lights off, stop arm in, bus moving | Loading finished | Move off slowly and watch for children |
When you must stop: road layouts
| Road type | Traffic behind the bus | Oncoming traffic |
|---|---|---|
| Two-lane road | Stop | Stop |
| Multi-lane road with no median | Stop | Varies by state (California: no need to stop with two or more lanes each way) |
| Road with a center turn lane only | Stop | Varies by state; stop unless your handbook clearly says otherwise |
| Divided highway (raised median, grass strip or barrier) | Stop | Some states, such as California and Georgia: you may continue with care. New York: stop. |
| Parking lots and school grounds | New York: stop | New York: stop |
When the rule is unclear, stop.
School bus rules in example states
- New York: traffic from either direction must stop, even on the opposite side of a divided highway, on multi-lane roads, in parking lots and on school grounds. Stop at least 20 feet from the bus. Fines run from $250 for a first violation to $1,000 for three violations in three years, and stop-arm cameras are authorized.
- California: traffic in both directions must stop for flashing red lights, unless the bus is on the other side of a divided or multilane highway (two or more lanes in each direction). Passing a bus with flashing red lights is a critical error on the drive test.
- Georgia: drivers on the opposite side of a highway divided by a median do not have to stop, but should watch for children. Georgia’s DDS describes four-lane roads with a center turn lane as requiring all traffic to stop, while a 2018 Attorney General opinion read the law differently, so check the current statute (O.C.G.A. 40-6-163).
- Texas: stop from either direction. Only traffic on a road with separate roadways (a barrier or unpaved median, not just a center turn lane) may continue. Fines run from $500 to $1,250 (Transportation Code 545.066).
- Indiana: on a road divided by a barrier or unimproved median, only traffic going the same way as the bus stops.
- Maryland: stop at least 20 feet from the bus, whether you are in front of it or behind it.
- Missouri: no stop is required when you are going the opposite way on a highway with four or more lanes, or on a road split into separate roadways. A conviction brings 5 points and a court suspension (90 days for a first offense).
- Wisconsin: stop at least 20 feet away, from both directions, except across a divided highway.
State guides: New York school bus law, North Carolina school bus law and Florida school bus rules.
Before you move off again
- Wait for all three: red lights off, stop arm in, bus moving.
- Look for children who are late, who dropped something or who are crossing behind you.
- Pull away slowly. Children may not look before crossing.
Common questions
Do you have to stop for a school bus on the other side of the road?
On an undivided road, yes, in every state. On a divided highway, it depends on the state. New York requires you to stop; California and Georgia do not, if the road is properly divided.
Does a center turn lane count as a divided highway?
Not always. Georgia, for example, limits its exemption to roads separated by a grass median, unpaved area or physical barrier under a 2019 change described by its Attorney General, and its own sources disagree on turn lanes. Stop if unsure.
How far back should I stop?
New York says at least 20 feet. Check your own handbook for its figure.
Can I pass a school bus with flashing yellow lights?
Yellow lights mean the bus is about to stop. Slow down and prepare to stop instead of trying to get past.
Can a camera on the bus give me a ticket?
In some states, yes. New York allows school districts and cities to use stop-arm cameras, and the fine goes to the vehicle owner.
