Grote Warning-Lamp Request: FMCSA Opens New Comments Through November 19
New technical explanations distinguish amber collision warnings from brake-activated lamps. The October 20 notice seeks comments before an exemption decision.
What the October 20 notice actually does
FMCSA has reopened comments on supplemental information about Grote Industries’ requested exemption for its Rear-End Collision Warning system. The request concerns auxiliary warning lamps and the requirement that exterior lighting generally be steady-burning. Comments are due November 19, 2026, under docket FMCSA-2026-0100. This notice is a request for comments before the agency decides the exemption application. It grants no new installation permission and announces no new mandate for drivers or fleets.
The clarification worth reading carefully
According to the notice, Grote now describes the collision-warning function as pulsing amber for up to four seconds, without then turning steady red. Grote says a separate brake-activated function takes priority if braking and a collision-warning event occur together. For doubles and triples, the manufacturer describes installing the system on the rearmost unit. Those are the applicant’s explanations recorded by FMCSA. They should not be presented as an agency finding that the equipment improves safety. The distinction between a warning about an approaching vehicle and an indication tied to braking is central to understanding the new material.
Drivers can make the feedback more concrete
Our editorial suggestion is to read the supplemental memorandum before commenting. Think about what a following driver would understand, what information a maintenance technician would need and how a carrier would explain the system to a newly assigned driver. Separate direct operating experience from a prediction. If you have not used the proposed configuration, describe your concern as a question or opinion. A useful comment explains the setting, the reason for the concern and what evidence would help answer it. Avoid simply repeating a sales claim or assuming every flashing auxiliary lamp is covered by the same request.
How to follow the docket
Use the linked Federal Register notice and its Regulations.gov docket route, select the notice and follow the comment instructions. FMCSA asks comments to address the new supplemental information; unrelated issues are outside this reopened comment period. Public comments can expose information included in the submission, so review what you attach. Keep a copy and submission confirmation for your records. If an equipment purchase depends on the outcome, return to the docket for the agency’s eventual decision and its actual scope. A request, a comment deadline and an approval are different steps.
