The California Department of Motor Vehicles lifted a ban on autonomous vehicles over 10,001 pounds, effectively allowing manufacturers to test and deploy heavy-duty driverless vehicles in the state.

According to Reuters, public agencies and universities will be allowed to operate medium-duty autonomous vehicles up to 14,001 pounds. "The new regulations also expand safety ‌and oversight requirements ⁠for ⁠all classes of autonomous vehicles, the California DMV said in a statement."

Manufacturers must begin testing with safety drivers before progressing to driverless operation and must complete 500,000 miles of testing at each phase. "However, ⁠vehicles will ‌still be required to stop at patrol stations and comply with state and federal commercial motor vehicle rules."
