Fog

Driving in fog can feel like driving while wearing a blindfold. Objects, such as other vehicles or traffic signals, may not be visible until the last moment – sometimes too late to take proper corrective action.

The two most important safety measures when you driving in fog are to slow down and turn on your low-beam headlights. By reducing speed, you increase available reaction time. And driving with your low-beam headlights on helps you to see the roadway more clearly and increases your visibility.

Additional tips for driving in fog

  • Use your windshield wipers to increase your visibility and reduce glare from oncoming vehicles.
  • If your vehicle is equipped with daytime running lights (DRLs), you may need to manually turn on your headlights, so your tail lights will also be illuminated.
  • Avoid sudden stops – and remember that larger vehicles need more distance to slow down or stop.
  • If you must stop, steer off the roadway as far as safely possible.
  • In severe fog, emergency flashers may help increase you visibilty to other drivers. (Check state laws regarding use of flashers while moving.)
