FMCSA Exemption Gives Driverless Trucks the Green Light

Federal regulators have granted Aurora Operations Inc. and other qualifying autonomous trucking operators a five-year exemption allowing driverless commercial trucks to use cab-mounted amber warning beacons instead of roadside warning triangles when stopped.

Exemption Addresses Driverless Truck Operations

The Federal Motor Carrier Safety Administration’s exemption is intended to address a requirement that normally relies on a human driver leaving a stopped truck to place reflective warning devices near the vehicle. A driverless truck cannot perform that task without assistance.

Under the exemption, qualifying Level 4 commercial trucks may use flashing warning beacons mounted high on the cab to alert approaching traffic. The exemption applies to Aurora and other carriers that meet the agency’s requirements and notify FMCSA in writing of their plans to operate under the exemption.

Aurora Previously Operated Under Temporary Waivers

Aurora initially sought relief from the traditional warning-device requirement in 2023. FMCSA later issued the company a series of temporary waivers, including one effective Oct. 10, 2025.

Aurora reported that 34 trucks operated with the warning beacons during the waiver period and traveled more than 500,000 miles. The company’s application said the beacons were used as an alternative to roadside warning devices on its driverless vehicles.

Industry Groups Raised Concerns

The exemption faced opposition from some trucking organizations. The Small Business in Transportation Coalition argued that the policy could create different standards for autonomous and human-driven trucks. The Owner-Operator Independent Drivers Association also urged FMCSA to complete its review of warning devices for stopped commercial vehicles before approving a broader exemption.

Despite those concerns, FMCSA approved the five-year framework for Aurora and other eligible autonomous trucking carriers. The exemption is expected to provide a uniform process for companies operating driverless commercial trucks that cannot deploy traditional roadside warning devices.
