Tire Chains State Laws

Understanding state laws regarding tire chains is crucial when driving in snowy or icy conditions. These laws help ensure road safety and provide guidelines for the proper use of tire chains. It's important to familiarize yourself with the regulations specific to your state or the states you plan to travel through. Here's an overview of tire chain laws in the United States:

1. California: In California, tire chains are required to be carried by vehicles traveling in certain mountainous areas during designated snow chain control periods. When chain control is in effect, vehicles must have either snow tires or be equipped with chains on the tires. The specific chain control requirements are determined by the California Department of Transportation (Caltrans) and are indicated by signs along the roadways.
2. Colorado: Colorado has similar laws regarding tire chains. During winter weather conditions, vehicles may be required to use chains or have snow tires, depending on the specific traction law in effect. In some cases, vehicles equipped with approved snow tires or traction devices like tire chains may be exempt from certain restrictions.
3. Oregon: In Oregon, vehicles traveling on designated mountain routes are required to carry chains between November 1 and April 1, unless otherwise specified by the Oregon Department of Transportation (ODOT). When "Chains Required" signs are posted, vehicles must install chains on their tires unless they have approved traction tires (studless, studded, or all-weather tires) on the drive axle(s).
4. Washington: Washington state requires drivers to carry chains in their vehicles during designated winter travel periods on certain mountain passes. When signs indicate that chains are required, all vehicles, including those with all-wheel drive, must have chains on their tires, unless they have approved traction tires. The Washington State Department of Transportation (WSDOT) determines the specific requirements.
5. Nevada: Nevada's tire chain laws are similar to those in other states. During winter weather conditions, vehicles may be required to use chains or have snow tires, as indicated by posted signs. The Nevada Department of Transportation (NDOT) provides information and updates on chain requirements for specific routes.

It's essential to check the specific requirements and regulations for each state you plan to travel through, as tire chain laws can vary. Additionally, be aware that failure to comply with these laws may result in penalties, fines, or restrictions on travel.

Remember to always exercise caution and drive at appropriate speeds when using tire chains, as they improve traction but do not guarantee complete control on slippery roads.
