Final answer:
You must stop your vehicle when a school bus with red lights flashing is approaching and remain stopped until the lights are off and the bus moves.
Step-by-step explanation:
When you see a school bus with red lights flashing approaching from in front or behind you, you are required to stop your vehicle. This safety rule is designed to protect children as they enter or exit the bus. By law, you must remain stopped until the red lights are turned off and the bus begins moving again. This law applies to vehicles traveling in both directions, unless there is a physical median or barrier between your vehicle and the school bus. Approaching drivers must always exercise caution and be prepared to stop for school buses to ensure the safety of students.
