VIDEO: How to Drive in the Fog

Spring rains can often mean fog is on the horizon. Dense fog poses a serious driving situation because few conditions restrict visibility more than dense fog.

It's important to be prepared and know what to do when the fog rolls in and you're behind the wheel.

Experts off the following advice for driving in fog:

  • Turn on your wipers and defrosters: Choose the intermittent windshield wiper setting to sweep away water as it deposits on the outside of the glass, and direct enough defroster air to the inside of the windshield and side windows to prevent them from fogging.
  • Switch your headlights to low beam: The higher the headlights, the more the fog will reflect light back in your eyes. If you have fog lights, try them to see if they improve the situation.
  • Slow down: As with any inclement weather, drive with caution. Don't drive faster than you can stop within the distance you can see ahead.
  • Keep a safe distance from the vehicle ahead: Other vehicles may do something sudden or unexpected due to the driver's limited visibility, so give yourself extra space and ample reaction time.
  • Follow the painted lines or the edge of the road as guidelines: Use the right edge of the road as a guide, rather than the centerline.
  • Don't rely on the taillights of the car ahead to lead the way: If that car goes off the road, you'll follow it.
  • Brake smoothly and early: Make sure your brake lights warn drivers behind. Pay attention to any sign of slippage when braking as fog may also form ice on the road surface.
  • Don't attempt to pass other vehicles: In fog, it is best to take your time and do not pass other cars as you may not be able to see stopped or oncoming vehicles, even with their lights on.
  • Be aware that fog conditions may not be uniform: Fog typically occurs in low-lying areas. When going down steep inclines, fog may suddenly accumulate and can get dramatically worse without warning so be prepared.
  • Breathe: Take a deep breath now and then. Experts say the extra oxygen you take in will sharpen your vision temporarily and help you relax.
