The California Teamsters union files a lawsuit against the state Department of Motor Vehicles (DMV) and multiple related agencies, arguing that California’s approval process for self-driving trucks does not comply with state requirements. The complaint, filed in Alameda County, says officials failed to complete the extensive economic study and practical impact assessment that state law requires before adopting or approving new regulations.

The union also argues that the regulations could create major workforce impacts, with estimates suggesting that roughly 400,000 people could lose their jobs if self-driving trucks replace human-driven roles. The suit challenges how the state evaluates and implements the rules for autonomous trucking rather than contesting a single pilot project.

The state agencies named in the lawsuit are accused of procedural deficiencies in how they carry out required reviews. The case is ongoing, and the filings indicate the union seeks legal relief related to the regulatory process.
