I. Public Participation and Request for Comments

FMCSA encourages you to participate by submitting comments and related materials.

A. Submitting Comments

If you submit a comment, please include the docket number for this notice (FMCSA-2026-0100), indicate the specific section of this document to which the comment applies, and provide a reason for suggestions or recommendations. You may submit your comments and material online or by fax, mail, or hand delivery, but please use only one of these means. FMCSA recommends that you include your name and a mailing address, an email address, or a phone number in the body of your document so the Agency can contact you if it has questions regarding your submission.

To submit your comment online, go to https://www.regulations.gov/​document/​FMCSA-2026-0100-0002, click “Comment,” and type your comment into the text box on the following screen.

If you submit your comments by mail or hand delivery, submit them in an unbound format, no larger than 8 1/2 by 11 inches, suitable for copying and electronic filing.

FMCSA will consider all comments and material received during the comment period. Comments received after the comment closing date will be filed in the public docket and will be considered to the extent practicable.

B. Confidential Business Information (CBI)

CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to the notice contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to the notice, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission that constitutes CBI as “PROPIN” to indicate it contains proprietary information. FMCSA will treat such marked submissions as confidential under the Freedom of Information Act, and they will not be placed in the public docket of the notice. Submissions containing CBI should be sent to Brian Dahlin brian.g.dahlin@dot.gov, Chief, Regulatory Evaluation Division, Office of Policy, FMCSA, 1200 New Jersey Avenue SE, Washington, DC 20590-0001 or via email at brian.g.dahlin@dot.gov. At this time, you need not send a duplicate hardcopy of your electronic CBI submissions to FMCSA headquarters. Any comments FMCSA receives not specifically designated as CBI will be placed in the public docket for this notice.

II. Background

On February 9, 2026, FMCSA published in the Federal Register a notice requesting public comment on an application from Grote for an exemption from the requirement that exterior lighting devices on CMVs be steady-burning, with a comment deadline of March 11, 2026 (91 FR 5798). The Commercial Vehicle Safety Alliance (CVSA) filed a comment to the public docket requesting that the comment period be extended by 60 days. CVSA stated that the extension of time would allow its membership to discuss the proposed exemption request during CVSA's 2026 Workshop, which is scheduled for April 19-23, 2026.

The Agency finds it is appropriate to extend the comment period to provide interested parties additional time to submit their responses to the notice. Accordingly, FMCSA extends the comment period until May 10, 2026.
