Due to icy weather and snow accumulation on the roads, many cars have installed snow chains to prevent accidents. The principle of snow chains is to concentrate the vehicle's weight onto a few points on the chain, generating immense pressure that forces the chain through the ice and snow to reach the road surface, thereby increasing friction and improving driving safety.
Here are some basic facts about snow chains to help everyone travel safely. Installing snow chains is a skill most people may never need in their daily lives. However, for those of you living in cold climates, it is extremely useful.
It might sound daunting, but installing and removing chains is actually a very quick process, even in freezing weather. With 15-30 minutes of expert guidance, you can immediately drive safely and reliably in winter. You can install and remove chains in your driveway or other relatively safe locations.
Of course, when you must install or remove chains on the road, always do so on a safe and flat section of road. Wherever you are, make sure you have at least 10 feet of clearance in front of and behind your vehicle to allow enough room to move the chain. Also, make sure your parking brake is engaged before you touch anything near the tires to prevent an accident.
Stabbing the tires with wooden blocks as an additional safety measure is a good idea. Finally, but equally important, clear any excess snow from your tires.
