Old drivers' automobile basic knowledge literacy

Old drivers must have the basic knowledge of automobile literacy-snow chains, how to drive on snowy roads.

After it snows in winter, roads and overpasses freeze everywhere, and traffic accidents are 1 times more than usual. You should walk carefully in case you fall! The rough surface of anti-skid chain increases the friction with the road surface, which usually plays the role of protecting tires, preventing tires from slipping and ensuring the normal running of vehicles in snow and muddy road conditions. Especially on snowy roads in winter, it can effectively ensure the smooth running and driving safety of vehicles.

Anti-skid chain is generally made of steel chain or rubber chain, which has anti-skid function. According to the structure, snow chains can be divided into two types: one is the snow chain that has been connected into a covering shape; The other is the cross installation of several independent chains, which is simpler and cheaper, but the installation is not as convenient as the former. Snow chains can be used not only on icy roads, but also to try to get out of trouble when tires slip.

There are many kinds of snow chains. The traditional iron snow chain is the most common and practical one. Their advantages are cheap and durable, and long driving distance, but they are more troublesome to disassemble and assemble, and the driving noise is relatively loud.

Rubber chains are mostly rubber grids with many metal nails or metal particles on them to increase adhesion. Advantages are simple, beautiful, wear-resistant and elastic, but the price is expensive, 200-300 yuan is even higher, but long-distance driving is easy to break down, driving noise will not be great, and tire damage will not be great.
