On a two-lane roadway, what must traffic in both directions do when approaching a stopped school bus?

When approaching a stopped school bus on a two-lane roadway, all traffic in both directions is required to stop. This rule is in place to ensure the safety of children who are getting on or off the bus. The law mandates that vehicles must remain stopped until the school bus's stop sign arm is retracted and its red lights are turned off, indicating that it is safe to proceed. This regulation extends to both directions of traffic because children may cross the road unpredictably, and stopping all traffic helps minimize the risk of accidents in such situations. Ensuring safety around school buses is crucial for protecting vulnerable pedestrians, particularly children who may not be aware of traffic dangers.
