Tire Chains laws in California
California law mandates that commercial vehicles, including those with combinations of vehicles, must be equipped with tire chains when entering areas where chain controls are in effect. These controls are typically implemented in mountainous regions during winter weather conditions. Drivers are required to install chains on designated drive wheels as indicated by roadside signs or law enforcement personnel. The California Department of Transportation (Caltrans) determines when chain controls are necessary based on road and weather conditions. Failure to carry or properly install chains when required can result in penalties. While carrying chains is generally allowed, their use is strictly regulated. Commercial vehicles are often subject to stricter chain requirements than passenger vehicles, sometimes needing chains on more wheels. It is crucial for commercial drivers to be aware of current chain control levels, which range from 'R-1' (chains required for vehicles with certain exceptions) to 'R-3' (chains required on all vehicles, no exceptions).
