Aurora Innovation made international headlines when it launched the first driverless commercial trucking service operating on public roads in the United States. In 2025, the company launched perhaps the most important real-world testing for autonomous freight systems by conducting regular self-driving freight shipping between Dallas and Houston, Texas. Based on Aurora’s publicly available safety disclosures, the main questions surrounding autonomous commercial fleets are not whether autonomous systems can satisfy safety objectives; rather, whether regulations originally written with a human driver in mind can be interpreted or amended to accommodate a vehicle operating with full autonomy.
From a statutory perspective, autonomous tractor-trailers appear capable of satisfying many of the substantive goals underlying Federal Motor Carrier Safety Administration (FMCSA) regulations. The FMCSA’s regulations center on reducing crashes, injuries, and fatalities involving commercial motor vehicles. If autonomous systems can demonstrate safety performance equal to or exceeding that of human drivers, they would arguably satisfy that objective. The FMCSA’s exemption framework already allows relief from certain regulations when an applicant can demonstrate an equivalent or greater level of safety, suggesting that the existing legal architecture contains mechanisms for gradual integration of autonomous trucking technology.
However, many FMCSA regulations could prove challenging for companies looking to develop their own autonomous fleet. The FMCSA regulations setting forth core requirements concerning commercial driver’s licenses, driver qualification files, medical certification, pre-trip and roadside inspections, hours of service compliance, and breakdown protocol were all drafted assuming there would be a human taking the helm of these 80-ton vehicles. An argument could be made that some of these requirements would simply be obsolete with the development of self-driving technology, remote operation, and electronic tracking. Yet, regulators may be wary of biting off too much, too fast.
Rather than creating a wholly separate regulatory body for autonomous commercial vehicles, the FMCSA has begun adapting existing safety standards and using exemptions, guidance documents, and liberal interpretations to address emerging issues. For example, the FMCSA has created exceptions for hours-of-service limits and drug testing requirements for self-driving commercial trucks. Thus, the FMCSA appears to be taking an incremental rather than a revolutionary approach. Congress has also taken steps towards paving the way for autonomous fleets to become a nationally recognized method of shipping and receiving.
Recently, the United States House of Representatives has proposed an amendment to title 49 of the United States Code by way of the America Drives Act. The Act will specifically allow semi-truck operation without a human driver or remote human operator, provided the truck qualifies as a Level 4 or Level 5 Automated Driving System (ADS). The Act sets a target date of September 30, 2027, for the Secretary of Transportation to address the applicability of many of the FMCSA regulations, which would only apply to human-piloted trucks. Perhaps most importantly, the Act prohibits the FMCSA from creating any regulations that “unduly burdens motor carriers operating ADS-equipped vehicles or discriminates against an ADS-equipped vehicle relative to other commercial motor vehicles.”
We can expect many new developments in this field over the next few years as technology continues to develop and autonomous commercial operations become nationally recognized. At the very least, it appears commercial trucking regulators are ready to accommodate the needs of motor carriers looking to expand their fleet with self-driving vehicles.
