Everything You Need to Know About Chain Laws
Updated: Feb 15
The weather is beginning to get a little cooler across the United States and some of the higher elevations are beginning to see snow. That means it’s time to freshen up on the chain laws in the states that you regularly run.
Alabama
The use of tire chains shall be permitted upon any vehicle when required for safety because of snow, rain, or other conditions tending to cause a vehicle to slide or skid.
Alaska
You are not permitted to use chains from May 1 through September 15 when north of 60 North Latitude.
You are not permitted to use chains from April 15 through September 30 when south of 60 North Latitude.
If you are operating a vehicle on Sterling Highway, you are not permitted to use chains from May 1 through September 15.
You will need to obtain a special permit from the Department of Administration if you would like to use chains in one of these prohibited zones.
Arizona
The use of tire chains are allowed when required for safety during a time of snow, ice, or another condition that might cause slippery highways.
Arkansas
The use of tire chains are allowed when required for safety during a time of snow, ice, or another condition that might cause slippery highways.
California
California does not require trucks to carry chains during any specified time period. When the weather hits, though, it takes at least eight chains for a standard tractor-trailer configuration to comply with the regulations.
During the winter months, there might be traction chain controls in the mountain areas. When these are established you will see signs posted along the highway. These signs will also include the type of requirement, which will include one of the following:
R1 - Chains, traction devices or snow tires are required on the drive axle of all vehicles except four wheel/ all wheel drive vehicles.
R2 - Chains or traction devices are required on all vehicles except four wheel/ all wheel drive vehicles with snow-tread tires on all four wheels.
R3 - Chains or traction devices are required on all vehicles, no exceptions.
