203. 霧
霧は視界を大幅に低下させ、速度、距離、他の道路利用者の位置を判断しにくくします。運転者は減速し、車間距離を増やし、他者を眩惑しない適切な灯火を使います。前車だけを目印にせず、視界が突然変化することにも備えます。非常に濃い霧では、安全な場所へ停止することが最善の場合があります。
Why is fog dangerous when driving?
Fog can greatly reduce visibility and make it harder to judge speed, distance and the movement of other road users.
How should you drive in fog?
Reduce speed, increase your following distance and use the appropriate lights. Drive so that you can stop safely within the distance you can clearly see.
Should you use high-beam headlights in fog?
Usually not. High beams can reflect from the water droplets in fog and make visibility worse. Use the lighting permitted and recommended under local traffic rules.
When should fog lights be used?
Fog lights are intended for conditions where fog or similar weather significantly reduces visibility. The exact rules for front and rear fog lights vary between countries.
Should you follow the lights of the vehicle ahead in fog?
No. You should maintain your own safe speed and following distance. Following another vehicle too closely can be dangerous because visibility and stopping distance remain limited.
What should you do if fog becomes extremely dense?
If visibility becomes too poor to continue safely, slow down and consider stopping at a safe place away from moving traffic until conditions improve.
