Fog is in the Air; Learn How to Stay Safe While Driving
Posted at 11:30 a.m.
We’ve had a couple of mornings recently with pretty dense fog, which can make the morning commute difficult. According to the National Weather Service (NWS), fog contributes to numerous travel accidents each year because it restricts drivers’ visibility.
If you must drive in foggy conditions, follow these safety tips from:
- Slow down and allow extra time to reach your destination.
- Leave plenty of distance between you and the vehicle in front of you to account for sudden stops or changes in the traffic pattern.
- Always keep your low-beam headlights on, even during the day. Use fog lights if you have them.
When necessary, NWS issues two types of fog advisories — a dense fog advisory, like the one we had this morning — and a freezing fog advisory.
- A Dense Fog Advisory is issued when widespread dense fog develops. When this happens, visibilities frequently drop to one-quarter of a mile or less. These conditions make travel difficult. Take extra caution when on the road or avoid driving if possible.
- A Freezing Fog Advisory is issued when fog develops and surface temperatures are at or below freezing. The tiny liquid droplets in the fog can freeze instantly to any surface, including vehicles and road surfaces. Freezing fog makes driving, boating, flying and other forms of transportation particularly hazardous. Visibilities are typically at or below 1 mile.
When fog and other weather conditions are present, please remember to allow some extra driving time. Arrive alive! And be sure to sign up for weather alerts from Fairfax Alerts so you’ll be in the know before you go about bad weather conditions.
