Fog or Heavy Smoke

It is best to avoid driving in heavy fog or smoke. Consider postponing your trip until the fog clears. If you must drive in heavy fog or smoke:

• Drive slowly.
• Use your low-beam headlights. High-beam headlights will reflect back and cause glare.
• Never drive using only your parking or fog lights.
• Make sure you can stop within the space you can see ahead.
• Increase your following distance.
• Use your windshield wipers and defroster as necessary.
• Avoid crossing lanes or passing traffic unless absolutely necessary.
• Listen for traffic you cannot see.

If the fog becomes too thick to drive safely, consider pulling off the road. Activate your emergency flashers and wait for conditions to improve.
