In short
Reduce to the posted school zone speed limit (typically 15–25mph) when the warning lights are flashing or kids are present. Stop fully for school buses with flashing red lights — failing to stop is a critical error.

School zone speed limits
School zones have reduced speed limits during posted hours, usually marked by flashing yellow beacons. Drive at the posted speed (typically 15–25mph) any time the lights are active, the hours apply, or you see children.
School buses
When a school bus stops with red flashing lights, all traffic must stop — including oncoming traffic in some states (varies by state divider rules). Failing to stop is a critical error and a $200+ ticket.
Frequently asked questions
Do I stop for a school bus on a divided highway?
Depends on the state and the type of divider. In most states, only traffic in the same direction must stop. Oncoming traffic stops only if there's no median.
