California DMV Publishes Final AV Regs for Heavy-Duty Trucks
New rules released April 28 open path for driverless Class 8 testing on California highways after 13-year rulemaking process.
California's Department of Motor Vehicles published final autonomous vehicle regulations April 28 that for the first time authorize heavy-duty autonomous truck testing and deployment in the state. The rules cover both light- and heavy-duty vehicles and mark the end of a rulemaking process that began around 2014.
When can autonomous truck companies start testing Class 8 rigs in California?
The regulations took effect upon publication April 28. Companies can now apply for permits to test autonomous heavy-duty trucks on California highways under a framework that has been in development for eight to thirteen years, depending on how the timeline is counted. Ariel Wolf, partner and chair of the Autonomous and Connected Mobility Practice Group at Venable LLP, confirmed the regulations are published and final.
What the California AV framework requires
California's approach is more prescriptive than the frameworks adopted by at least 26 other states that have embraced autonomous vehicle testing. The state has long led in robotaxi regulation but lagged in heavy-duty autonomous trucking. Many companies based in California have had to test their Class 8 rigs in states such as Texas because no clear regulatory path existed in-state.
The new regulations give companies a measured path forward. The DMV's April 28 release strengthens oversight and enforcement while authorizing trucks and transit vehicles. The rules are described as "California-flavored" — detailed legislation and rulemaking on high-profile issues that takes years by design.
Political and procedural obstacles to reversal
The regulations have been in development since around 2014. That long timeline makes any quick reversal politically and procedurally difficult, even if California's gubernatorial election produces a new administration opposed to autonomous trucking deployment. Wolf noted the regulations are done and published, the product of more than a decade of work.
Whether the rules lead to widespread deployment, a measured rollout, or an outright reversal may depend in part on the outcome of the gubernatorial race. But the procedural weight of a 13-year rulemaking process creates significant inertia.
What carriers operating in California need to know
Carriers running California lanes should expect to share highways with autonomous test vehicles in the coming months. The regulations authorize both testing and eventual deployment, though the DMV's framework is described as measured rather than permissive.
Companies that have been testing autonomous Class 8 trucks in Texas and other states can now apply for California permits. The state's approach differs from the less prescriptive frameworks in place elsewhere, so carriers familiar with autonomous truck testing in other jurisdictions should review California's specific requirements.
The rules do not address operating authority or insurance requirements specific to autonomous carriers beyond what the DMV published. Carriers considering autonomous technology or sharing lanes with autonomous test vehicles should monitor DMV guidance as the first permits are issued and the framework moves from paper to pavement.
