How Should I Prepare My Vehicle for Foggy Conditions?

• Use Low-Beam Headlights: Turn on your low-beam headlights to enhance visibility. Avoid high beams, as they can reflect off the fog and worsen visibility. (weather.gov)

• Activate Fog Lights: If your vehicle is equipped with fog lights, use them to improve road illumination.

• Engage Windshield Wipers and Defroster: Keep your windshield clear by using wipers and the defroster to remove moisture.

What Driving Techniques Are Recommended in Dense Fog?

• Reduce Speed: Slow down to match the reduced visibility, allowing more time to react to sudden changes. (weather.gov)

• Increase Following Distance: Maintain a greater distance from the vehicle ahead to account for sudden stops.

• Use Road Markings as Guides: Follow the right edge of the road or painted road markings to stay in your lane. (weather.gov)

• Avoid Sudden Maneuvers: Make smooth and deliberate steering, braking, and lane changes to prevent accidents.

• Be Alert for Stopped Vehicles: Watch for slow-moving or parked vehicles that may be difficult to see in foggy conditions.

What Should I Do If Visibility Becomes Extremely Low?

• Pull Off the Road Safely: If you cannot see, pull completely off the road into a safe location, such as a parking lot or rest area. (ioem.idaho.gov)

• Activate Hazard Lights: Turn on your hazard flashers to alert other drivers of your presence.

• Avoid Stopping on the Road: Do not stop on the road unless absolutely necessary, as this can pose a hazard to other drivers.

How Can I Stay Informed About Fog Conditions?

• Use Reliable Weather Apps: Utilize weather applications that provide real-time updates on fog conditions and advisories.

By adhering to these guidelines, you can enhance your safety and the safety of others when driving in dense fog.
