The Federal Motor Carrier Safety Administration (FMCSA) has denied Waymo LLC and Aurora Operations, Inc.'s application for an exemption from certain safety regulations related to Commercial Motor Vehicles (CMVs) operated by Level 4 Automated Driving Systems. The companies sought to use "Cab-Mounted Warning Beacons" as an alternative to the traditional warning devices required when a CMV is stopped on the highway. Although public comments showed some support, the FMCSA decided that the proposed beacons did not demonstrate an equivalent or greater level of safety. The application was too vague and lacked necessary details and data to justify a nationwide exemption for all autonomous CMV operators.
Simple Explanation
The government said "no" to Waymo and Aurora's idea to use special lights on their self-driving trucks because they weren't sure the lights would be safe enough. They wanted more details and tests to prove that these new lights would be just as good as the old ones for keeping everyone safe on the road.
