What must you do when you see an emergency vehicle with flashing lights?

Answer: B — Pull over to the right and stop

When you see an emergency vehicle with flashing lights, the appropriate action is to pull over to the right side of the road and stop. This response is crucial for the safety of both the emergency personnel and other road users. By moving to the right, you create a clear path for the emergency vehicle to pass through efficiently. It’s important to remain stopped until the emergency vehicle has passed or until you are instructed otherwise by an officer. This behavior not only complies with traffic laws but also demonstrates respect for the urgent nature of the emergency situation. Maintaining this protocol helps to ensure that emergency responders can reach their destination without delay, thus potentially saving lives or preventing further emergencies.
