What actions must you take when driving in fog?

When driving in fog, using low beams and reducing speed is essential for maintaining visibility and ensuring safety. Low beams are specifically designed for conditions with reduced visibility, as they illuminate the road directly in front of the vehicle without causing excessive glare that can happen with high beams. High beams reflect off the moisture in the fog, creating a wall of light that can obscure rather than enhance visibility.

Reducing speed in fog is equally important because it allows for greater reaction time to sudden obstacles or changes in traffic conditions. Fog can make it difficult to gauge distance, speed, and the behavior of other vehicles, so traveling at a slower speed helps ensure the driver can respond appropriately to potential hazards. It is crucial to drive cautiously and be prepared to stop if necessary, and maintaining a safe distance from other vehicles is also advisable in these conditions.

By following these guidelines—using low beams and reducing speed—drivers can improve their chances of navigating safely through foggy conditions without increasing risks on the road.
