When driving in fog, using low-beam headlights and reducing speed is crucial for safety. Low-beam headlights provide adequate illumination without creating a glare that reflects off the fog, which can make visibility even worse. They allow you to see the road ahead clearly while minimizing the reflection that can be produced by high-beam headlights in foggy conditions.

Additionally, reducing speed is essential because fog can significantly impair your ability to see other vehicles, traffic signals, and road signs. Slowing down gives you more time to react to any obstacles or sudden changes in traffic, making it safer to navigate through low-visibility conditions.

Using high-beam headlights counteracts the goal of improving visibility because the light bounces off the water droplets in the fog and can create a blinding effect. Driving as usual in foggy conditions isn’t advisable, as standard driving speed and visibility practices may lead to dangerous situations. Relying solely on fog lights may not provide sufficient visibility for all situations, especially in dense fog. Therefore, the best practice is to utilize low-beam headlights and adjust your speed appropriately.
