What must drivers do when approaching a stopped school bus displaying stop signals?

When approaching a stopped school bus that is displaying stop signals, the regulations require all drivers to stop in order to ensure the safety of children boarding or exiting the bus. This is particularly important as children are often unpredictable and may suddenly run into the roadway.

In the case of a divided highway, certain laws allow drivers on the opposite side of the divided roadway to continue without stopping. However, if there are no physical barriers, all drivers must stop. It's crucial to understand that the requirement applies universally; regardless of your position relative to the bus, if you are in a situation that necessitates stopping, it is imperative to do so, especially in scenarios where children may be crossing.

Additionally, the option indicating only rear drivers must stop is misleading because the law mandates it for all drivers in proximity to the stop signals, regardless of their position on the road. The idea that all drivers must stop unless they are on a four-lane road also places unnecessary conditions on safety.

Thus, the most comprehensive and correct answer is that all drivers must stop when a school bus displays stop signals, with exceptions clearly outlined by the type of road. This holistic understanding is crucial for the safety of everyone involved.
