Are train horns legal in West Virginia?
Installing an aftermarket train horn on a private vehicle in West Virginia is not prohibited. WV train horn law is in W. Va. Code §17C-15-33 — “Horns and warning devices.” Standard UVC pattern: 200-ft audibility, “unreasonably loud or harsh sound” ban, use limited to safe-operation cases, and sirens/whistles/bells barred on non-emergency vehicles.
Install is legal; use on WV public roads — Charleston, Huntington, Morgantown, Parkersburg, Wheeling, Martinsburg — is the regulated behavior.
What W. Va. Code §17C-15-33 actually says
(a) Every motor vehicle when operated upon a highway shall be equipped with a horn in good working order and capable of emitting sound audible under normal conditions from a distance of not less than two hundred feet, but no horn or other warning device shall emit an unreasonably loud or harsh sound or a whistle. The driver of a motor vehicle shall when reasonably necessary to insure safe operation give audible warning with his horn but shall not otherwise use such horn when upon a highway.
(b) No vehicle shall be equipped with nor shall any person use upon a vehicle any siren, whistle, or bell, except as otherwise permitted in this section.
Operative rules: 200-ft audibility · no unreasonably loud or harsh sound or whistle · no siren/whistle/bell (authorized emergency vehicles exempt) · safe-operation use limit · optional theft alarm on commercial vehicles (subsection (c)).
Updated 2026-10-24: corrected the statute number. Earlier versions of this page cited W. Va. Code §17C-15-28 as the horn statute. §17C-15-28 actually covers unapproved lamps and lighting equipment; the horn and warning-device rules quoted above are §17C-15-33. The quoted text matches the official West Virginia Code, and the section’s bill history shows no change since its 1951 enactment, so the law itself has not changed and the page’s status (“legal” to install) is unchanged. Re-verified against the West Virginia Legislature’s official code site on 10/24/2026.
Does the factory horn need to stay working in WV?
Yes. §17C-15-33 applies to the vehicle as a whole.
