The new regulations also expand safety and oversight requirements for all classes of autonomous vehicles, the California DMV said in a statement.

Here are a few details:

  • The move lifts the ban on operating autonomous vehicles weighing over 10,001 pounds, opening California to autonomous freight operations.
  • However, vehicles will still be required to stop at patrol stations and comply with state and federal commercial motor vehicle rules.
  • Medium-duty autonomous vehicles up to 14,001 pounds will be allowed to be operated by public agencies and universities.
  • In 2023, California Governor Gavin Newsom vetoed a bill to prevent heavy-duty driverless trucks from operating in the state.
  • The DMV had since been working toward developing a regulatory framework to lift that restriction.
  • The new rules require manufacturers to begin with testing using a safety driver and progress to driverless testing before applying for commercial deployment.
  • Manufacturers must complete 50,000 miles for light-duty vehicles and 500,000 miles for heavy-duty vehicles for testing at each phase.
