What should you do if there is a stopped school bus with flashing lights that is loading or unloading passengers on a two-lane highway?

Answer: B — Stop until the bus moves

When you encounter a stopped school bus with flashing lights on a two-lane highway, the law requires you to stop your vehicle until the bus resumes movement. This is a critical safety measure designed to protect children who are getting on or off the bus. The flashing lights signify that children may be crossing the road, which increases the risk of accidents if motorists do not stop. Stopping ensures that you are giving children ample time and space to safely enter or exit the bus without the danger of oncoming traffic. It is important to remain alert during these moments, as children can be unpredictable and may unexpectedly cross the road. This rule applies to vehicles traveling in both directions unless you are on the opposite side of a divided roadway. By stopping for a school bus, you contribute to a safer environment for children, who are often in a vulnerable position while using school transportation.
