WASHINGTON (Reuters) - The U.S. Senate Commerce Committee plans a hearing next Wednesday on the future of self-driving commercial trucks that will include the chief executive of Navistar International Corp and safety advocates.

A U.S. House bill aimed at speeding self-driving vehicles to market that faces a vote Wednesday does not include changes to allow fully autonomous commercial trucks on U.S. roads, but some senators want to include commercial trucks.

The Teamsters union has praised efforts to keep self-driving commercial trucks out of a proposed bill aimed at speeding deployment of the advanced technology for cars, warning that truck driver jobs may be at risk.
