US Postal Service to test mail shipments on self-driving trucks

PHOENIX — A self-driving truck company has partnered with the U.S. Postal Service to test autonomous technology on the long-haul route between Phoenix and Dallas.

San Diego-based TuSimple is planning for two autonomous trucks to carry mail and parcels on five round trips between the Postal Service distribution centers in the two cities starting Tuesday.

TuSimple says a safety engineer and a driver will be on board to monitor the trucks during the two-week pilot program.

The trucks use a camera system allowing the vehicles to view about 3,280 feet ahead.

The company says the Postal Service has contracted TuSimple to examine if the technology could reduce fuel costs, increase safety and improve fleet operation.
