FMCSA approves warning beacons for autonomous trucks
Agency provides long-sought 5-year exemption

Key Takeaways:
- FMCSA granted Aurora and other Level 4 autonomous truck operators a five-year exemption allowing warning beacons instead of roadside triangles.
- The exemption, effective Oct. 7 through Oct. 7, 2031, removed what Waabi called the last obstacle to safely scaling autonomous truck deployment.
- Aurora, Volvo Autonomous Solutions, Waabi, PlusAI and Torc Robotics planned to expand commercial autonomous trucking operations in 2027.
Autonomous truck software developers and original equipment manufacturers received a boost in recent days from the Federal Motor Carrier Safety Administration, which OK’d the use of beacons rather than warning triangles for five years.
The decision followed a yearslong campaign from the software developers, particularly publicly traded Aurora Innovation, to obtain approval of an alternative to the triangles drivers must deploy behind trailers when pulled over on the side of the highway.
A truck without a driver is a prerequisite for deployment of Level 4 or 5 autonomous trucks, but the conundrum of how to alert fellow motorists before a support vehicle arrives when a problem arises posed an existential question for autonomous trucking companies.
Aurora first sought an exemption in January 2023. FMCSA initially rejected the petition. Aurora appealed, won three-month waivers and then resubmitted its petition in April.
Pittsburgh-based Aurora’s persistence was rewarded Oct. 7 when FMCSA Administrator Derek Barrs revealed exemptions would be granted to the company and its peers at the Autonomous Vehicle Industry Association’s 2026 Autonomy Summit in Austin, Texas.
In a Federal Register notice Oct. 9, FMCSA confirmed the agency had granted a five-year exemption to Aurora and “other motor carriers operating Level 4 automated driving system (ADS)-equipped commercial motor vehicles (CMVs), with prior notice to FMCSA.”
FMCSA said in the notice it had “determined that granting the exemption would likely achieve a level of safety equivalent to or greater than the level of safety provided by the regulation.” The exemption was effective Oct. 7 and expires Oct. 7, 2031.
“This decision underscores the government’s recognition of the immense economic and community benefits of autonomous trucking. High-visibility, cab-mounted warning beacons are a critical, 21st-century solution that enhances roadside safety by immediately alerting other road users without ever needing to put a person in harm’s way. This exemption is a meaningful step forward in making our roads safer for everyone,” Gerardo Interiano, SVP of government relations and public affairs at Aurora, said in a statement provided to Transport Topics.
The green light for beacons rather than triangles comes as Aurora and its peers ready for a pivotal year for autonomous trucking in 2027.
Aurora will pick up the pace on the road to 30,000 self-driving trucks on American highways equipped with its Aurora Driver software plus the accompanying hardware. Aurora expects to end 2027 with more than 1,000 trucks on the road, pulling in $200 million in revenue and posting positive gross profit. The company has posted losses of $200 million or more in recent quarters.
Meanwhile, Aurora’s partner, Volvo Autonomous Solutions, as well as autonomous trucking rivals, such as Waabi, PlusAI and Torc Robotics, are set to ramp up operations to commercial scale in 2027. Tesla is also promising to launch self-driving trucks.
Waabi Chief Operating Officer Lior Ron told TT on Oct. 14 that the FMCSA decision was a pivotal step for the autonomous trucking sector.

“I think it’s a historical step for FMCSA to take the step and finally officially remove the last blocker for scale deployment of autonomous trucks safely on the road,” the former Uber Freight executive said.

AVIA, meanwhile, framed the exemption as the latest in a series of initiatives from the Trump administration that have been supportive of the industry.
Included in those initiatives is the first federal policy framework regulating the deployment of self-driving trucks that is part of the five-year surface transportation reauthorization bill released in May — the BUILD America 250 Act.
The framework — Safe Integration of Autonomous Commercial Motor Vehicles — would create a performance-based safety standard for commercial motor vehicles equipped with automated driving systems.
