No roadside warning triangle for automated trucks

As discussed in a Federal Register notice published March 3, 2023, FMCSA is seeking comment on an exemption request filed by Waymo and Aurora that would exempt automated trucks from the regulations that require specific placement of warning devices around a stopped CMV.  The exemption would allow all motor carriers operating ADS-equipped CMVs without a human on board (or with a human on board), when stopped upon the traveled portion or the shoulder of a highway for any cause other than necessary traffic stops, to use a warning system consisting of forward- and rearward-facing cab mounted flashing amber lamps mounted at a height above the upper edge of the sideview mirrors instead of the currently required warning devices placed around the CMV, as described in 49 CFR 392.22(b).  Comments on the exemption request are due in April.
