What action should you take when driving in foggy conditions?

When driving in foggy conditions, using low-beam headlights is crucial for safety. Low-beam headlights provide illumination at a level that helps you see the road directly in front of you without causing significant glare. Fog tends to reflect light, and high-beam headlights can create a blinding effect, making visibility even worse. Low beams cut through the fog more effectively, allowing you to see and be seen by other drivers without reflecting excessive light back into your eyes.

Driving at the speed limit in fog can be hazardous, as visibility is likely compromised, and you may need to adjust your speed to maintain safe control. Following other vehicles closely is also dangerous in fog, as it can limit your ability to react to sudden changes. Staying further back allows for better reaction time and distance to stop safely.
