What should you do when driving in fog?

When driving in fog, using low-beam headlights and increasing your following distance is crucial for safety. Low-beam headlights are designed to illuminate the road directly in front of your vehicle without causing a glare that can reflect off the fog, which could impair visibility further. This is in contrast to high-beam headlights, which can reflect off the moisture in fog and create a blinding effect, making it harder for you to see.

Additionally, increasing your following distance is important because visibility is significantly reduced in fog. This allows you more time to react to any sudden changes in traffic or road conditions. By giving yourself extra space, you can help ensure a safer driving experience even when visibility is compromised.

Driving at the speed limit in foggy conditions may not be safe, as the limit assumes ideal visibility and conditions. Likewise, turning off your headlights would severely diminish your ability to see ahead and be seen by other drivers, creating a dangerous situation on the road. Therefore, using low-beam headlights and increasing following distance is the appropriate response in foggy conditions.
