What should you do when emergency vehicles approach in the opposite lane on an undivided highway?

When emergency vehicles approach in the opposite lane on an undivided highway, it is crucial to pull over to the edge of the road and stop until the emergency vehicle passes. This action ensures the safety of both the emergency responders and other motorists. By stopping, you allow the emergency vehicle to navigate the road without interference, which is especially important when they are responding to a critical situation.

Stopping is necessary because emergency vehicles often need to move swiftly and may also change lanes suddenly; thus, being stationary reduces the risk of accidents. Additionally, if you're on an undivided highway, the other lanes are likely close by, and stopping also provides extra clearance from the vehicle that may need to maneuver around other cars.

Continuing to drive at the same speed or decelerating without stopping does not guarantee safety for the emergency responders and may create a hazardous environment if other drivers are not aware of their approach. Pulling over to the left is inappropriate as it may place you in the path of oncoming traffic or the emergency vehicle itself, leading to potential collisions.
