What can we add to snow tires to improve their grip?
Safe driving
Explanation
To improve the **traction** of snow tires, **chains** can be used. These are placed on the driving wheels of the vehicle and are especially useful when driving in snowy conditions. Chains help the tires grip the road better, which is crucial since, in snowy conditions, tires tend to lose traction, increasing the distance needed to brake safely.
The R-412 sign indicates the obligation to use chains in certain snowy conditions, which reinforces the importance of this device to maintain safety when driving in these situations. Chains are a practical and effective solution to improve tire traction on snowy roads.
