5 tips for driving in fog

Fog creates dangerous driving conditions by reducing visibility on the road. Your local National Weather Service office will issue an advisory when fog reduces visibility to 1/8 mile or less within the advisory area. Train your employees on driving in adverse weather conditions as part of their occupational driving safety program. Follow our tips to stay safe when driving in foggy conditions.


1Wait it out

If at all possible, don’t drive until the fog lifts – usually by late morning or afternoon.

2Light the way

Use fog lights and low-beam headlights. Do not use high beams – they cause glare and make it harder to see the road ahead. Use the right edge of the road or roadside reflectors as a visual guide. Turn on your vehicle’s four-way flashers so it is easier for other vehicles to see you.

3Go slowly

Fog makes the road wet. Reduce your speed and allow plenty of reaction time and stopping distance around you. Don’t forget to use your windshield wipers and defroster to maximize visibility.

4Be alert

Fog can thicken without warning. Be ready for other vehicles’ emergency stops, and watch out for slow-moving and parked vehicles. Do not use cruise control in foggy conditions so you have better control of your vehicle.

5Stay put

Don’t change lanes or pass other vehicles unnecessarily. If you change lanes, signal early. If you cannot see, pull completely off the road and park your vehicle, preferably at a rest area. Turn on only your hazard flashers and set the emergency brake.
