Back to School 2025 — School Zone Safety and Accident Liability

Arizona schools are back in session, and that means a sudden shift in traffic patterns. School zones activate, buses are on the road, and thousands of children are walking, biking, and crossing streets during morning and afternoon hours.

School Zone Laws in Arizona

Under Arizona law, the speed limit in a school zone is 15 mph when children are present or during posted times. Violations carry enhanced fines. Passing a stopped school bus with its stop sign extended is a serious traffic violation.

These laws exist because children are unpredictable — they dart into streets, emerge between parked cars, and don’t always look before crossing. Our crash data shows the 3–6 PM window is the deadliest time on Phoenix roads — and that overlaps directly with school dismissal.

Liability for School Zone Accidents

A driver who injures a child in a school zone faces an uphill battle. The reduced speed limit means any driver going faster than 15 mph was violating the law — establishing negligence per se. And the comparative fault defense is weak against a child — Arizona law recognizes that children can’t be held to the same standard of care as adults.

Bus Stop Safety

Children are most vulnerable when boarding and exiting school buses. Arizona law requires all traffic in both directions to stop when a school bus has its stop sign extended. Drivers who blow past stopped school buses face criminal penalties and devastating civil liability if they hit a child.
