What must drivers do when police, fire, or rescue vehicles approach from behind?

When police, fire, or rescue vehicles approach from behind, drivers must pull over to the right edge of the road and stop until the emergency vehicle passes. This practice is necessary to ensure that emergency responders can reach their destination quickly and safely without obstruction. Pulling over to the right provides a clear path for emergency vehicles, which often need to navigate through traffic at high speeds to respond to urgent situations.

In Virginia, as in many other states, this rule is part of the law designed to prioritize the movement of emergency responders. Stopping at the right edge of the roadway helps to keep the driver's vehicle out of the way while also allowing other vehicles that may not have heard or seen the emergency vehicle to also pull over.

The other options presented do not align with the required actions for drivers in these situations. For instance, yielding to the left side of the road can complicate traffic flow and does not guarantee a clear passage for the emergency vehicle as expected. Accelerating to get out of the way could create a hazardous situation, as it might lead to accidents by creating confusion in traffic. Ignoring the emergency vehicle altogether is not only dangerous but also illegal, as this disregards the necessary protocol to allow emergency responders to function effectively.
