What should you do if there is an emergency vehicle directly behind you in heavy traffic?

In situations where an emergency vehicle is directly behind you in heavy traffic, the appropriate action is to keep moving slowly until it is safe to maneuver out of the way. This approach allows you to maintain control of your vehicle while also ensuring that you do not create additional hazards by stopping suddenly in the lane, which could lead to rear-end collisions with other vehicles.

Keeping a slow pace helps to maintain flow in heavy traffic, making it easier for the emergency vehicle to navigate around you as it attempts to reach its destination efficiently. It's crucial not to make sudden movements, like changing lanes quickly or pulling over abruptly, as this could confuse other drivers and potentially lead to unsafe conditions on the road.

While other options might suggest immediate actions that seem proactive, they do not account for the intricacies of heavy traffic and the need to maintain safety for all drivers. Always prioritize gradual and deliberate movements in such circumstances to ensure everyone's safety.
