This comes as light snow covered the roadway as seen on the Mt. Laguna Live Cam, located on the S1 Scenic Byway on Sunrise Highway.
Chain control level one, also referred to as Requirement 1 (R-1), means chains are required on all vehicles except passenger vehicles and light-duty trucks. Those trucks, according to Caltrans, must be under 6,000 pounds gross weight and have snow tires on at least two drive wheels.
