What is the first thing to do when driving in fog?

  1. Turn on high beams

  2. Flash lights from low to high

  3. Turn on all lights on low beams

  4. Slow down

The correct answer is: Turn on high beams

When driving in fog, it is important to turn on all lights on low beams to make your vehicle more visible to others. Using high beams can actually make it harder to see because the bright light can reflect off the fog and create a glare. Additionally, slowing down is crucial in foggy conditions to give yourself more time to react to any obstacles or other vehicles that may suddenly appear in front of you. Flashing lights from low to high is not recommended as it may confuse other drivers and increase the risk of accidents.
