Practice question

What should drivers do in foggy conditions?

  1. Use high-beam headlights and increase speed
  2. Use low-beam headlights and reduce speed
  3. Drive with hazard lights on and maintain speed
  4. Drive at the speed limit and use regular headlights

Answer: B — Use low-beam headlights and reduce speed

In foggy conditions, using low-beam headlights and reducing speed is essential for safety. Low-beam headlights are designed to provide better illumination closer to the road, which is crucial in foggy weather as high beams can reflect off the moisture in the air, creating a blinding glare that reduces visibility further. Additionally, decreasing speed allows drivers more time to react to sudden changes in traffic conditions or obstacles that may not be visible until they are close. This combination of low-speed and appropriate lighting helps ensure maximum visibility and safety for both the driver and others on the road.
