What should you do if you encounter an emergency vehicle with flashing lights?

Answer: B — Pull over to the right side of the road and stop

When you encounter an emergency vehicle with flashing lights, the appropriate response is to pull over to the right side of the road and come to a complete stop. This action ensures that the emergency vehicle has a clear path to maneuver through traffic, allowing them to reach their destination as quickly and safely as possible, which is crucial in emergency situations. By stopping on the right, you also prevent confusion and potential accidents that could arise from moving vehicles blocking the path of the emergency vehicle. This rule applies in most jurisdictions, emphasizing the importance of yielding to emergency responders to maintain public safety.
