What action is required when you hear a siren or see lights from an emergency vehicle?

When you hear a siren or see lights from an emergency vehicle, the appropriate action is to pull over to the right and stop. This response is crucial for several reasons. First, it ensures that emergency vehicles, such as ambulances, fire trucks, or law enforcement, can pass safely and reach their destination without delay. These vehicles are often responding to urgent situations where time is of the essence.

Pulling over to the right allows for a clear path, making it easier for the emergency vehicle to maneuver through traffic. Stopping your vehicle is important because continuing to drive, even at a reduced speed, could lead to confusion and obstruct the emergency vehicle's route. Therefore, following this protocol helps maintain safety for all road users while facilitating the effective functioning of emergency services.

The other options suggest actions that might exacerbate the situation or create hazards on the road, which is why they do not align with proper safety measures.
