Driving in snow presents challenges due to the **reduced grip** of the tires on the road. This means that the vehicle needs more space to brake and it is more difficult to control the car. One of the recommendations to improve safety when driving in these conditions is to **drive over the tracks left by other vehicles**.

When other vehicles pass through the snow, they compact the snow on the ground, which can offer a firmer and more stable surface for the wheels. This improves the grip of the tires, making it easier to control the vehicle and reducing the risk of slipping. Therefore, following the tracks of other cars is an effective strategy to improve traction and safety when driving in the snow.
