Driving a commercial truck through Santa Cruz County? Know the rules before you get on the road! The Legal Truck Access Branch within the California Department of Transportation (Caltrans) oversees size and weight issues for legal, non-permitted trucks so that large trucks may travel legally and safely on State highways.
Not sure on which routes your truck may legally travel? Use the Quick Guide to determine your truck category and find state and local routes on which your vehicle is allowed. On Routes 9 and 236 in Santa Cruz County, trucks with KPRA (King Pin to Rear Axle length) of 30′ or greater are not recommended, but not officially prohibited.
There are approximately 20 State route segments with specific truck restrictions throughout California, including number of axles, gross weight, length, and cargo type (e.g. flammables, explosives, radioactive materials). Highway 152 between Watsonville and Gilroy is the only State route in Santa Cruz County with these special restrictions. There are NO special route restrictions for Highway 17.
