When You Must Stop for a School Bus in South Carolina

You must stop when a school bus stops with its red lights flashing and stop arm extended

South Carolina law requires you to stop your vehicle whenever a school bus displays its red flashing lights and extends its stop arm, whether you are behind the bus, meeting it head-on, or approaching from a side street. You must remain stopped until the red lights stop flashing and the stop arm is retracted. This applies on all roads — highways, rural roads, and city streets — except when the bus is stopped on the opposite side of a divided highway with a physical barrier between the lanes.

The only exception to this rule is when a police officer or school crossing guard is directing traffic at the location. In that case, follow the officer's or guard's directions instead of the automatic stop rule.

Violating this law carries serious penalties. A first offense costs a minimum of $100 and up to $500 in fines. A second offense within three years costs a minimum of $200 and up to $1,000. A third or subsequent offense within three years can result in fines up to $1,000 and suspension of your driver's license for up to six months.

What the red lights and stop arm mean

The red flashing lights and extended stop arm are signals that the bus is loading or unloading children. When you see these signals, treat them as a mandatory stop sign — not a suggestion or a caution. The bus driver activates these signals before opening the door and keeps them on until all children have boarded or exited and are clear of the roadway.

Yellow flashing lights mean the bus is preparing to stop and is slowing down. You should begin slowing your vehicle when you see yellow lights, but you are not required to stop unless the red lights come on. However, you should be ready to stop at any moment.

How far back you need to stay

South Carolina law does not specify a minimum distance you must maintain behind a stopped school bus. However, you must come to a complete stop and remain stopped. The safest practice is to stay far enough back that you have a clear view of the bus's signals and can see if children are crossing the road in front of or behind the bus.

If you are on a multi-lane road, you should not attempt to pass a stopped school bus in any lane. Wait until the red lights stop flashing and the stop arm is fully retracted before proceeding.

Divided highways and when you do not have to stop

If a school bus is stopped on the opposite side of a divided highway — meaning there is a physical barrier, median, or guardrail separating the directions of traffic — you do not have to stop. The barrier prevents children from crossing into your lane, so the law does not require you to stop.

However, if the highway is divided only by a painted line or if there is no physical barrier, you must stop even if the bus is on the opposite side. Many drivers mistakenly believe they can proceed when the bus is across the road, but the law is clear: stop unless there is a physical barrier.

What happens if you are cited for not stopping

If a police officer observes you failing to stop for a school bus, you will be issued a citation. You can pay the fine, contest the citation in traffic court, or request a hearing. If you choose to contest it, you may present evidence that you did stop, that the bus was on a divided highway with a barrier, or that a police officer was directing traffic at the time.

The citation will be reported to the South Carolina Department of Motor Vehicles and will appear on your driving record. Multiple violations within three years can result in license suspension, which means you will not be able to drive legally in South Carolina or any other state.

School bus safety for drivers behind the bus

When you are following a school bus, watch for the yellow warning lights. These typically come on 100 to 300 feet before the bus comes to a stop. Reduce your speed and prepare to stop completely. Do not assume the bus will turn or continue straight — school buses make frequent stops, and you need to be ready at each one.

Never try to pass a school bus that is slowing down or has its yellow lights on. Wait until the red lights are off and the stop arm is fully retracted. Even then, proceed cautiously in case the bus suddenly stops again or a child runs back into the road.

Meeting a school bus head-on

If you are traveling in the opposite direction and encounter a school bus with red lights flashing and stop arm extended, you must stop just as if you were behind it. This applies even on a two-lane road where passing is normally allowed. The bus is loading or unloading children who may cross the road in front of the bus into your lane.

Stop your vehicle completely and remain stopped until the lights and stop arm are no longer active. Do not proceed until you are certain the roadway is clear and the bus signals have been deactivated.

Frequently Asked Questions

Do I have to stop if I am on a side street and the bus is on the main road?

Yes. If you are approaching the main road from a side street and the school bus on the main road has its red lights flashing and stop arm extended, you must stop before entering the main road. The law applies regardless of which road is larger or which direction the bus is traveling.

What if the school bus is parked but not loading or unloading children?

If the red lights are not flashing and the stop arm is not extended, the bus is not actively loading or unloading. You may proceed normally. However, always drive cautiously around parked buses and be prepared to stop if the lights suddenly activate.

Can I pass a school bus on a two-lane road if the lights are not on?

Yes, you may pass a school bus on a two-lane road if the red lights are off and the stop arm is retracted. However, treat it like passing any other vehicle — ensure the road ahead is clear, use your turn signal, and do not exceed the speed limit. Proceed cautiously in case the bus suddenly stops.

Do school bus stopping rules apply at night?

Yes. The red flashing lights and stop arm are active whenever the bus is loading or unloading children, regardless of the time of day or night. You must stop whenever you see these signals, even in darkness or poor visibility.

What should I do if a school bus driver waves me through?

If a school bus driver signals you to proceed, you may do so, but only if it is safe and the red lights have been turned off. The driver's gesture does not override the law, but drivers sometimes turn off the lights before all children have cleared the road. Look carefully before proceeding and be prepared to stop if you see a child in the roadway.
