How should you handle a situation where you see a school bus with warning lights on?

Answer: B — Stop your vehicle and wait until it is safe to pass

In situations where a school bus is displaying warning lights, the appropriate action to take is to stop your vehicle and wait until it is safe to pass. The activation of the warning lights indicates that children may be boarding or exiting the bus, which significantly increases the risk of accidents. Stopping your vehicle ensures the safety of children who may be in the vicinity and allows them to cross the road safely, as they might not be visible to you while you are driving. This practice is not only a legal requirement in many areas, including those governed by U.S. military regulations in Germany, but it reflects responsible driving behavior. Drivers sharing the road with school buses must always prioritize the safety of children, who can be unpredictable and may not look out for oncoming vehicles. Thus, stopping until the bus has turned off its lights and it is safe to proceed is crucial for ensuring everyone's safety on the road.
