If a vehicle in front of you stops while traveling in the center lane on a highway during an emergency call, what should you do?

When approaching a vehicle that has stopped in front of you while traveling in the center lane on a highway during an emergency call, it is crucial to respond in a manner that ensures both your safety and that of other road users. Reducing speed and passing on the left is the correct action because it allows you to maintain control of the emergency vehicle while safely maneuvering around the stopped vehicle.

By braking to reduce speed, you are taking a responsible approach that helps prevent any sudden stops or collisions. Passing on the left is typically the safest option, as it allows you to avoid the stopped vehicle while keeping a safe distance from it. It also aligns with common driving practices and legal guidelines, which often require drivers to yield to emergency vehicles and to pass with caution.

Honk to alert the driver, accelerate to pass, or come to a complete stop may not be appropriate actions in this situation, as they can lead to confusion or unsafe conditions on the highway. Each of those alternatives lacks the critical focus on safety and control that is necessary when navigating around a stopped vehicle under emergency circumstances.
