Fog has reduced visibility so severely that you cannot continue safely. What should you do?
Correct answer: B – Use low beams and move completely off the travel lane before stopping
Use low-beam headlights in fog because high beams may reflect from moisture in the air and shorten the distance you can see. If conditions make it necessary to stop, move as far off the traffic lane as possible before doing so. Do not leave the vehicle stopped in a lane used by moving traffic.
