Weather, Visibility & EmergenciesStandalone practice
Fog sharply reduces how far a driver can see. What is the safest adjustment?
Blue car A is centered in its eastbound lane on a two-way road in fog. The car and road edges remain readable. Opposing traffic lanes have two solid yellow lines.
Correct answer: Slow so you can stop within sight; use low beams.
Why
Lower speed preserves stopping room, while low beams reduce glare reflected by fog.
