Vehicle Loads


Vehicle Load Permit Research at Caltrans is a newly developed program. The aim of this program is:

  • To improve the mobility of goods across California
  • To improve the safety of the public during travel
  • To improve the ride quality of the driver in the existing system
  • To develop and foster new and evolving technology related to vehicle load system

We will work closely with Traffic Operations and Bridge Maintenance in Caltrans, Universities and industry to provide the best highway system for the people of California. We are also involved in national research projects that will provide a direct benefit to California and other states.
