What should you do when you hear a loud siren?

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

When you hear a loud siren, it is important to pull to the side of the road and stop. This is the correct protocol for emergency vehicles, such as ambulances or fire trucks, to safely pass by and reach their destination. Holding your ground and accelerating, or pulling ahead of the emergency vehicle, can put you and other drivers in danger and impede the emergency response. Speeding up is also not advisable, as it can make it difficult for the emergency vehicle to navigate and potentially cause an accident. Pulling to the side of the road and stopping allows the emergency vehicle to pass quickly and safely.
