The U.S. Postal Service (USPS) is conducting a two-week pilot study in which self-driving trucks complete a more-than-1,000-mile mail run between Phoenix and Dallas.
The test will utilize big rigs from autonomous trucking company TuSimple to haul trailers on five round trips between distribution centers in the two cities.
The trip normally takes about 22 hours with human drivers, and is serviced by outside trucking companies that use two-driver teams to comply with federal regulations limiting drivers' time behind the wheel.
The autonomous trucks are part of a USPS effort to cut operating costs and fuel expenses, and improve truck safety and use its fleet more efficiently.
