How should drivers react to emergency vehicles with flashing lights?

Answer: B — Pull over and stop until the vehicle passes

When encountering emergency vehicles with flashing lights, drivers should pull over and stop until the vehicle passes. This action ensures that emergency responders can navigate through traffic safely and quickly, which is vital during emergencies. It also helps prevent potential accidents by clearing the way for the emergency vehicle. This rule is essential for the safety of both the emergency personnel and the public. It allows them to respond to situations such as medical emergencies, fires, or police matters without obstruction. Maintaining a safe distance also minimizes the risk of endangering other road users or causing delays in emergency response. In contrast, continuing to drive at the same speed, driving closely to the emergency vehicle, or stopping only when the vehicle is blocking the road does not provide the necessary space and safety for emergency responders. These alternatives could obstruct the vehicle's path, creating dangerous situations for both the emergency personnel and other drivers on the road.
