School Buses: Practice Questions & Explanations

On a two-lane or undivided road, all traffic in both directions must come to a complete stop when a school bus has red flashing lights and the stop arm extended. Students may be crossing the road in either direction to reach the bus or their destination, and the school bus driver's signaling system protects them. The stop is required until the red lights stop flashing and the stop arm retracts. Penalties for passing a stopped school bus are severe in every state — typically $250-$1,000 first offense, with license suspension and points possible. Many jurisdictions use cameras on school buses to enforce the law.

On a divided highway with a physical median or barrier, most states require only traffic in the same direction as the bus to stop. Traffic on the opposite side of the barrier is presumed to be separated from any crossing students by the physical median. State laws vary on what counts as a 'divided' highway: a painted line is not enough in most states; a physical median (curbed, grassy, or barrier-separated) is required. Always verify your specific state's rule, and when in doubt, stop — a stopped car is never worse than a hit student. Even when stopping is not required, slowing down and being alert is best practice.

When a school bus stops and activates its flashing red lights and extended stop arm, you must stop and remain stopped — in most situations in both directions — until the lights stop flashing and the stop arm is withdrawn, because children may be getting on or off and crossing the road. On a divided highway with a physical barrier, drivers on the opposite side may not be required to stop, but the rules are strict and vary, so caution is essential. Illegally passing a stopped school bus carries severe penalties and endangers children. Stopping for a school bus with flashing red lights is one of the most important rules of the road.
