Special Route Restrictions

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. View the California Truck Network Map for more details (Santa Cruz County is part of District 5).
