When should snow chains be fitted?
Safe driving
Explanation
To drive safely in **snow** conditions, it is important to follow certain precautions. One essential measure is the use of **snow chains**. These chains should be placed on the vehicle's **driving wheels**, but only when the road is already covered with snow. This is because chains improve the grip of the tires on snowy surfaces, which is crucial for maintaining vehicle control and reducing braking distance.

The R-412 sign indicates the obligation to fit chains in order to continue driving in these conditions. Therefore, it is essential to wait until the road is snowy before putting on the chains, as their use on snow-free surfaces can damage both the chains and the road and does not provide the necessary traction benefit.
