FMCSA to allow self-driving trucks to use cab-mounted warning beacons in place of triangles

The Federal Motor Carrier Safety Administration (FMCSA) will grant an exemption from warning device placement requirements for autonomous trucks.

FMCSA Okays Previously Denied Exemption Ask Aurora initially applied for an exemption from the warning device placement requirements in 2023.

The Owner-Operator Independent Drivers Association (OOIDA) opposed Aurora’s exemption request and expressed disappointment at the FMCSA’s decision.

That’s why OOIDA submitted formal comments opposing the use of cab-mounted warning beacons.

Aurora filed a lawsuit against federal transportation authorities in January 2025 after its initial petition to use cab-mounted warning beacons in place of reflective warning triangles or flares was denied.
