OAKLAND, Calif. -- The California Department of Motor Vehicles has approved testing of heavy-duty autonomous vehicles, including semi-trucks, on the state's roads. William Hall, owner of Coyote Container at the Port of Oakland, supports the move.

"You ask any trucking company what their biggest problem is, it's usually the drivers. It's finding drivers, it's keeping drivers and it's keeping them safe and keeping them out of accidents. Those things are all, with automated trucks and driverless trucks, are easier to deal with." Teamsters California criticized the decision in a statement. "Make no mistake: this is just the beginning of Teamsters California's fight for good jobs and safety on our roads," the statement said. "The DMV's decision to rush forward with driverless heavy-duty trucks is reckless, and we will use every tool necessary to stop it - including taking this fight to the courts." WATCH: 'A Driverless Tomorrow': From farming to mining, self-driving trucks are how humans do basic tasks This week, for the first time, a driverless commercial truck delivered freight, completing a 230-mile route from Houston to Dallas on time. Timelapse video of that drive shows no one in the cab. The company, Bot Auto, argues that autonomous trucks are the future. Since there are no drivers, they don't face fatigue or need breaks, reducing overall costs. "We go where sometimes humans do not want to go. I-45 is very challenging. There's a lot of traffic," said Al Tete Xiao, VP of engineering at Bot Auto. Aurora, a Silicon Valley-based company, has been testing self-driving trucks in Texas since
