Dozens of truck drivers and teamsters rallied in San Francisco Friday.

They are concerned about the possibility that self-driving trucks could soon be on California roads, and they want to put the brakes on the testing and deployment of self-driving vehicles.

Today’s rally comes days after the CPUC delayed a vote on the unlimited expansion of Cruise and Waymo robotaxis throughout San Francisco.

Truck drivers and teamsters rallied on the steps of San Francisco City Hall Friday morning — angry about automated vehicles.

The San Francisco police and fire departments have criticized the self-driving cars for blocking emergency crews.

Demonstrators today said they’re also worried about the possibility of driverless trucks and big rigs coming to the Golden State.

“There have been other situations where they have driven right into a fire scene. So there is no way we should be having a discussion about trucks or larger vehicles,” said Mayor London Breed.
