Waymo’s self-driving trucking unit is partnering with Uber Freight to deploy a host of autonomous trucks.

The partnership will see Waymo customers use Uber Freight to more efficiently plan their human-operated and automated trucking fleets. Currently, Uber Freight’s software serves as a middle man and connects truckers with shippers. Doing so reduces shipping costs, Reuters notes.

Waymo Via isn’t the only company that Uber Freight is working with. Following the ride-hailing giant’s decision to sell its self-driving unit to Aurora in 2020, it has since partnered with Aurora through Uber Freight.

Alphabet’s self-driving division is looking to sell self-driving trucking services to large retailers and logistics companies. Under this plan, customers would purchase and own the self-driving trucks while also paying a per-mile usage fee to the company.

This isn’t the only significant partnership that Waymo’s self-driving trucking division has. The company has been working with UPS for more than two years and in November last year, commenced a series of autonomous trial runs with its Class 8 trucks equipped with the fifth-generation Waymo Driver system. These trucks conducted deliveries for UPS’s North American Air Freight unit between facilities in Dallas-Fort Worth and Houston.

Waymo is also working alongside Daimler on a fully autonomous, Level 4 system for trucks and is testing a fleet of Peterbilt trucks in Arizona, California, and Texas. Autonomous trucks currently being tested by Waymo have a commercially licensed driver and a Waymo software engineer in the cabin at all times.
