Show Answer & Explanation
Correct Answer: B. Pull off into a safe area and wait for the fog to lift, using low beams
In dense fog the handbook directs drivers to pull off into a safe parking area and wait. High beams scatter off water droplets and reduce visibility; stopping in the travel lane invites rear-end collisions; tailing another vehicle means you inherit their mistakes plus a collision risk when they brake.

- C.Stop in your traffic lane and turn on hazard lightsStopping in a live lane creates a rear-end collision hazard.
- D.Follow the tail lights of the vehicle ahead closelyFollowing another vehicle's tail lights closely causes chain collisions when they brake.
