When driving in fog, what should you use in order to improve visibility?

  1. High beams

  2. Parking lights

  3. Headlights

  4. Fog lights

The correct answer is: Headlights

When driving in fog, it is important to use your headlights to improve visibility. This is because fog lights are specifically designed to cut through fog and reduce glare, making it easier to see the road ahead. High beams and parking lights are not recommended in fog because high beams can reflect back and cause even worse visibility and parking lights are not bright enough to properly light the road.
