AUSTIN, Texas (AP) — The Texas House has approved safety standards for self-driving cars, hoping to better regulate technology that's already been tested on the streets of the state capital.

The bill by Sen. Kelly Hancock, a North Richland Hills Republican, mandates that autonomous vehicles comply with national traffic codes. The state could also supersede local regulations made to accommodate self-driving cars.

The House passed Hancock's measure via voice vote Saturday. It unanimously cleared the Senate last month, but House changes now send it back there.
