What FMCSA decided
FMCSA issued a final disposition granting Aurora Operations and other qualifying carriers a limited five-year exemption from specified warning-device placement, steady-burning lamp, and warning-device type and number requirements. The exemption is effective October 7, 2026 through October 7, 2031.
The order allows cab-mounted amber warning beacons on covered Level 4 automated-driving-system commercial vehicles in place of traditional warning devices. It is a final exemption, not a proposal or a nationwide change to the rules for every truck.
Which operations qualify
Aurora is covered, and another motor carrier may use the exemption only after providing written notice to FMCSA and meeting the order's terms. Operations must remain within the automated system's validated operational design domain.
The exemption does not cover operations that would require a hazardous-materials, passenger, school-bus or tank-related endorsement if a human driver were present, and it excludes longer-combination triple trailers. It also does not grant authority to operate on a route where federal or state law otherwise prohibits the operation.
Beacon and reporting conditions
The order specifies high-mounted amber beacons meeting stated visibility and equipment standards, redundant electrical power, automated activation no later than five minutes after the vehicle stops, and monitoring for system failures.
Participating carriers must submit annual reports about beacon malfunctions and related power issues. The order also requires specified crash reporting to FMCSA within five calendar days.
What it means for drivers
Drivers sharing the road may encounter a qualifying Level 4 truck using illuminated cab-mounted beacons rather than warning triangles when it is stopped. Slow down, move over when required and safe, and follow traffic-control or law-enforcement directions.
Human-driven commercial vehicles remain subject to the ordinary roadside-warning requirements unless another valid exemption applies. FMCSA said broader modernization may merit future action, but this order does not create that broader rule.
