There are 3 ways to and from Big Bear Lake, CA. During the winter months of November - April, motorists may encounter traction chain controls in the mountain areas within California. By law, snow chains or cables must be carried in your vehicle at all times during winter months.
BBMR does not sell or install tire chains. Contact your local auto parts store for tire chains availability and make sure you know how to install your traction devices before visiting BBMR to avoid delays when traveling to/from the mountains. For questions or concerns about road conditions, please contact the California Department of Transportation (CalTrans) directly at 1-800-427-7623.

Snow chains, also known as tire chains or cables, are required for safety when snow or ice conditions cause slippery highways. Check the road conditions before you head out to see if snow chains are required. There are 3 ways up and 3 ways home
from BBMR which means snow chains may be required on one highway and not the other, so you should always carry chains in your vehicle during the winter months, even if your car has snow tires. Tire traction devices are defined in the California Vehicle Code (VC) Section 605. View official chain requirements provided by dot.ca.gov
LEARN ABOUT SNOW CHAINS
You must stop and put on chains when highway signs indicate chains are required. You can be cited by the California Highway Patrol and fined if you don't. You will usually have about a mile between "Chains Required" signs and the checkpoint to install your chains.
- Control areas can change rapidly from place to place because of changing weather and road conditions.
- The speed limit when chains are required is 25 or 30 miles an hour.
- When you put on chains, wait until you can pull completely off the roadway to the right. Do not stop in a traffic lane where you will endanger yourself and block traffic.
- Chain Installers: If you use the services of a chain installer, be sure to get a receipt and jot the installer's badge number on it. Remember, chain installers are independent business people, not Caltrans employees. Having the badge number may help with any misunderstandings later. Chain installers are NOT allowed to sell or rent chains.
- When removing chains, drive beyond the signs reading "End of Chain Control" to a pull-off area where you can safely remove them.
CHAIN REQUIREMENT LEVELS
When chain controls are established, signs will be posted along the road indicating the type of requirement. There are Three Levels of Chain Requirements in California:
1 Snow-tread Tires: The California Vehicle Code, Section 558 defines a snow-tread tire as follows, "A 'Snow-tread tire' is a tire which has a relatively deep and aggressive tread pattern compared with conventional passenger tread pattern". Snow-tread tires can be identified by examining the sidewall of the tire where the letters MS, M/S, M+S or the words MUD AND SNOW have been stamped into the sidewall.
2 Tire Traction Devices: The California Vehicle Code, Section 605 defines tire traction devices as follows: "Tire Traction Devices are devices or mechanisms having a composition and design capable of improving vehicle traction, braking and cornering ability upon snow or ice-covered surfaces. Tire traction devices shall be constructed and assembled to provide sufficient structural integrity and to prevent accidental detachment from vehicles. Tire traction devices shall, at the time of manufacture or final assembly, bear a permanent impression indicating the name, initials or trademark of the assembling company or primary manufacturer, and the country in which the devices were manufactured or assembled in final form."
The full, searchable version of the California Vehicle Code is available at: Leginfo, the website for California Legislative Information.

Chains must be carried by vehicles using snow tires. All vehicles towing trailers must have chains on one drive axle. Trailers with brakes must have chains on at least one axle.
- Requirement 2 (R2): Chains or traction devices2 are required on all vehicles except four wheel/all wheel drive vehicles with snow-tread tires on all four wheels.
