How to drive safely in rain, fog and snow

Published on 17.11.2021

The scenery may be beautiful but driving in autumnal conditions can often be a challenge. Do not forget to adjust the lighting on your car to ensure that you can easily see and be seen.


Autumn is the season of fiery colours and golden forests, of slightly misty landscapes and snow-covered mountains; a real gift for artists, but for motorists it means leaving home in the dark in the morning and getting home in the dark at night, with sheets of fog, downpours and even billows of snow to contend with in between.

With this in mind, we thought we’d remind you of a few rules and tips that will make your journeys safer and less stressful, whatever the weather. It’s also a great opportunity to review how we should be using the various lights on our vehicles.
 

Caution and vigilance

The autumn brings with it lower levels of light and consequently reduced visibility, regardless of the weather conditions, meaning that driving requires greater care and attention and is more tiring. You’ll also need to adapt your speed and safety distances to the road conditions and your field of vision.
 

Inspections and maintenance

As autumn approaches, it's important to make sure your front and rear wiper blades are in good condition, that your tyres are appropriate to the season and not worn, and that all of your vehicle's lights are in good working order and properly adjusted. Once winter arrives, take  snow chains in the car so you don’t get caught out in the event of sudden snowfall in these circumstances, car equipment shops are quickly out of stock!
 

Using the different lights

Driving in rain

  • Dipped headlights allow you to see and be seen and must be switched on when visibility is less than 150m on motorways, 100-120m on secondary roads outside urban areas and 60-70m in urban areas. In the event of heavy rain, you can also turn on your front fog lights if visibility is 50m or less. The rear fog lights should not be used in rain. This is because water droplets distort the beam of light to the point where it dazzles the driver behind you.

 
Driving in fog
If dipped headlights are not effective enough, you should use your fog lights.

  • The beam to the front illuminates the road directly in front of your vehicle, which is handy when visibility is reduced to less than 50m.
  • While the rear fog lights ensure that you are clearly visible, but do be careful, as the latter can easily dazzle the driver of the vehicle behind you. Only use them when visibility is less than 50 m, and turn them off as soon as visibility improves again.
  • Full beams aggravate poor visibility and should not be used at all in fog.
 

Driving in snow
Our recommendations for driving in foggy weather also apply in the event of snow.
It’s so important that we adapt our behaviour when driving in snowy conditions, meaning no unnecessary braking, using engine braking, increasing your safety distances and heightened anticipation of other road-users’ reactions.

Automatic lights
If your vehicle is fitted with such a system, it won’t always detect low levels of light or fog, so get into the habit of turning on your dipped headlights manually.
Your fog lights must also be turned on and off manually.
 

All that being said, we wish you all the best on your journey with the ACL!
