"Snow removal and ice control shall be performed as necessary in order to facilitate the movement and safety of public traffic and shall be done in accordance with the best management practices outlined herein with particular emphasis given to environmentally sensitive areas."
Donner Pass
Snow and ice control is important on every mountainous route within California; however, certain routes carry heavy seasonal recreational traffic as well as high volumes of truck traffic. These routes require extensive snow-fighting activity to keep open during heavy snow storms.
Chain Controls
Chain Control Checkpoint
Chain controls are generally used during snowstorms and usually end soon after the end of the storm. However, with sunshine, the snow and ice pack will begin to melt resulting in slush on the pavement that is difficult to negotiate without tire chains.
Caltrans officials urge you to check road conditions often. To help keep abreast of changing conditions, Caltrans operates the Caltrans Highway Information Network which motorists may telephone 800.427.7623 for up-to-the-minute information in California and Western Nevada (Lake Tahoe/Reno Area). The network is updated as conditions change, and is voice-activated for safety and convenience.
