Avoiding Fog and Driving Safety

Do you ever notice that when you’re driving in fog and have to use your windshield wipers to guide your car, it’s difficult to drive without getting lost? In this article, we will point out how AI-powered software can help reduce the risks of a foggy day.

What is Fog?

In order to increase visibility, the ambient air temperature needs to be between 60 and 70 degrees Fahrenheit. If the air temperature is colder than this, you will experience fogging. Fog is a form of precipitation that forms when water vapor in the air condenses onto small particles of dust or salt and then freezes. In some cases, there are tiny droplets of liquid water that mix with the fog to create ice crystals.

How Fog Affects Driving

Wintertime brings many challenges for drivers. One of the biggest challenges is driving through fog. The US Department of Transportation (USDOT) reports that up to 3,000 people die per year from car accidents caused by driving in fog. The USDOT offers some tips for avoiding this dangerous risk such as keeping your speed under 40 miles an hour, scanning your mirrors frequently, and even wearing a seat belt on every trip.

Road Conditions in Fog

In foggy conditions, the air temperature is below freezing, and the water vapor in the air condenses. Fog also creates a reduction in visibility due to light scattering. It’s not only treacherous for drivers but also affects those who use motor vehicles and bicycles.


How to Develop a Driving Strategy

“A driving strategy is a simple plan for how you will drive during any trip or situation that you encounter.” There are three levels of driving strategies. The first level is when the weather is clear and visibility is good. The second level is when, even though visibility is not impaired, there may be other factors such as road construction or speed changes that require caution and a slower pace. The third level involves driving in poor weather conditions or during bad weather situations (i.e., snow, rain) where visibility may be low or nonexistent.

Tips for Avoiding Fog

One way for drivers to avoid fog is to avoid driving in areas where there is high humidity. This can be done by staying away from coastal areas and near bodies of water like rivers, lakes, reservoirs, and marshes. Drivers should also stay away from open fields, valleys, and mountain passes. Drivers should also plan their routes around the worst foggy times of day and use landmarks instead of relying on GPS.
