Washington, DC CNN  — 

Driverless trucks are officially running their first regular long-haul routes, making roundtrips between Dallas and Houston.

On Thursday, autonomous trucking firm Aurora announced it launched commercial service in Texas under its first customers, Uber Freight and Hirschbach Motor Lines, which delivers time- and temperature-sensitive freight. Both companies conducted test runs with Aurora, including safety drivers to monitor the self-driving technology dubbed “Aurora Driver.” Aurora’s new commercial service will no longer have safety drivers.

“We founded Aurora to deliver the benefits of self-driving technology safely, quickly, and broadly, said Chris Urmson, CEO and co-founder of Aurora, in a release on Thursday. “Now, we are the first company to successfully and safely operate a commercial driverless trucking service on public roads.”

The trucks are equipped with computers and sensors that can see the length of over four football fields. In four years of practice hauls the trucks’ technology has delivered over 10,000 customer loads. As of Thursday, the company’s self-driving tech has completed over 1,200 miles without a human in the truck.

Aurora is starting with a single self-driving truck and plans to add more by the end of 2025.

Self-driving technology continued to garner attention after over a decade of hype, especially from auto companies like Tesla, GM and others that have poured billions into the tech. Companies in the market of autonomous trucking or driving, tend to use states like Texas and California as their testing grounds for the technology.

California-based Gatik does short-haul deliveries for Fortune 500 retailers like Walmart. Another California tech firm, Kodiak Robotics, delivers freight daily for customers across the South but with safety drivers. Waymo, a subsidiary of Google parent company Alphabet, had an autonomous trucking arm but dismantled it in 2023 to focus on its self-driving ride-hailing services.

However, consumers and transportation officials have raised alarms on the safety record of autonomous vehicles. Aurora released its own safety report this year detailing how its technology works.

Unions that represent truck drivers are usually opposed to the driverless technology because of the threat of job loss and concerns over safety.

Earlier this year, the Federal Motor Carrier Safety Administration rejected a petition from autonomous driving companies Waymo and Aurora seeking to replace traditional warning devices used when a truck broke down with cab-mounted beacons. The Transport Workers Union argued the petition would hinder safety.
