1. Snow
Snow can make roads slippery, reduce visibility and greatly increase stopping distances. Drivers should reduce speed, increase their following distance and accelerate, steer and brake smoothly to avoid losing control. Snow or ice should be removed from the windows, mirrors and lights before driving, and suitable tyres or other winter equipment may be required depending on the country and road conditions.
How does snow affect driving?
Snow can reduce tyre grip, visibility and vehicle control and increase the distance needed to slow down or stop.
How should you drive on snow?
Drive more slowly, increase your following distance and use smooth acceleration, steering and braking. Sudden movements can cause the tyres to lose grip.
Should snow be removed from a vehicle before driving?
Yes. Remove snow and ice that obstruct the windscreen, windows, mirrors and lights. Snow should also be removed where it could fall from the vehicle and create a hazard for other road users.
Are winter tyres required when it snows?
This depends on the country. Some countries require winter tyres during certain periods or winter conditions, while others only recommend them.
When are snow chains used?
Snow chains can provide additional grip on roads covered with snow or ice. Rules for their use vary between countries, and some roads may require them when indicated by a traffic sign.
Should you use fog lights during snowfall?
Fog-light rules vary by country. They are generally intended for conditions where snow, fog or other weather significantly reduces visibility, so drivers should follow the applicable local rules.
