How to react and adapt to different road weather conditions

July 27, 2021
Foggy and rainy conditions have a significant impact on your safety

On average over 5,000 people are killed annually in over a million crashes caused by dangerous road weather conditions in the United States.

Most of them are caused by rain and the consequence of rain: wet pavements.

About a fourth of accidents are caused by snow and ice, and about 10% of the fatalities occur in foggy weather conditions.

It is thus important to know how to react and adapt to these potentially dangerous road weather conditions.

Driving through the rain and thunderstorms

Thunderstorms are one of the most common weather problems

One of the most common road weather conditions that you will encounter which can introduce safety issues is rain.

The intensity of rain can differ a lot: from a light drizzle to a full-on downpour and everything in between.

Light rain usually doesn’t cause many safety risks, but when it has been raining for a long period, there can be a layer of water on the road surface.

If there is such a layer, there is a risk of aquaplaning.

This means that the tires will slide over the water, the tires will lose grip and the driver will have more difficulties controlling the car.

The best advice to regain traction is to let loose of the gas pedal and thus lower your speed, and preferably don’t steer.

Thunderstorms are of a different calibre, they can come with high-intensity precipitation and even hail.

Thunderstorms are local and they don’t tend to last long. You can recognize them by their dark clouds, occasional lightning and a haze, this haze indicates precipitation.

If this haze is dark, the rain will be present, if it is more whitish, you may encounter hail.

When driving in heavy rain, lower your speed and keep enough distance to the vehicle in front of you.


In the case of hail, stay in the car

In the case of severe hail, pull over and stay in the car, even though your windshield may break, the hail will not be able to hurt you.

Ideally, you could park under an overpass, to save your car too.

If you’re driving on the highway, you will probably drive into the storm, instead of the storm moving into you, because storms generally travel slower than a car.

So keep an eye out in the direction you’re travelling for any storms.

But the easiest thing to do to know if you will encounter thunderstorms on your route is to check the radar in the Weather on the Way app.

Snow and frost, the most difficult road weather conditions?

Driving on snow-covered or icy roads isn’t a pleasure for most people.

The first and most important piece of advice is to just not travel in these conditions if you don’t need to.

You can take a look at the weather warnings on your route with the Weather on the Way app.

If you do need to travel, it would be a great benefit to have winter tires installed or have access to snow chains.

With snow and ice, the main danger is the potential to lose grip.

Don’t drive too fast and steer gently to prevent slipping.

Especially if there fell a lot of fresh snow recently, some roads will not be ploughed yet, which can cause another problem: risk getting stuck.

Having a snow shovel with you would be a great help in such a case.

Foggy conditions are relatively the most lethal

Foggy conditions are very dangerous

Even though only 3% of the weather-related accidents occur in foggy road weather conditions, 9% of the deaths are a result of those conditions.

Fog can be especially dangerous if the visibility is dynamically changing.

The big risk here is that you drive into a suddenly appearing fog bank, which reduces your sight immensely.

This has caused and is remaining to cause most of the deadliest pile-ups. In foggy conditions:
