The U.S. House unanimously approved on Wednesday a sweeping proposal to speed the deployment of self-driving cars without human controls and bar states from blocking autonomous vehicles.

The bill now goes to the Senate and would allow automakers to obtain exemptions to deploy up to 25,000 vehicles without meeting existing auto safety standards in the first year, a cap that would rise to 100,000 vehicles annually over three years.

The bill comes at a time where automakers and technology have been pushing for new federal rules making it easier to deploy self-driving technology.
