Short answer: owning a Train Horn for Milwaukee® 18v Battery in West Virginia is legal, but the state horn law has a line in it that a 150 dB chord walks straight into: no horn may emit an "unreasonably loud or harsh sound." I read the current text of the WV Code on the Legislature's own site before writing this, so here's what it says, how it plays with the inspection sticker on your windshield, and how I'd run a portable horn in the Mountain State.
What WV Code §17C-15-33 actually says
West Virginia's horn rule is §17C-15-33, "Horns and warning devices". The bill history on the Legislature's page lists one act: House Bill 189 from the 1951 regular session. So this is a 1950s rule being applied to 2020s hardware. Here's the part that matters, piece by piece:
- Equipment: every motor vehicle operated on a highway needs a horn in good working order, "capable of emitting sound audible under normal conditions from a distance of not less than two hundred feet."
- Sound quality: no horn or other warning device may emit an "unreasonably loud or harsh sound or a whistle."
- Use: the driver sounds the horn "when reasonably necessary to insure safe operation," and not otherwise.
- Sirens, whistles and bells: vehicles generally can't carry or use "any siren, whistle, or bell," with carve-outs for commercial theft alarms and authorized emergency vehicles.
There is no decibel number anywhere in it, and the words "air horn" and "train horn" never appear. That cuts both ways. Nobody can point to a 110 dB cap you broke, but "unreasonably loud or harsh" is whatever the officer on the shoulder of I-79 thinks it is.
The 200-foot rule is a floor, and "unreasonably loud" is the ceiling
A lot of forum posts read the 200-foot figure as a limit. It isn't. It's the minimum your horn has to reach. Your factory horn already clears it, and nothing in the statute says a horn can't be heard at 1,000 feet.
The ceiling is the "unreasonably loud or harsh" language, and this is where West Virginia is stricter on paper than some neighbors. Kentucky's horn statute, for example, only polices when you sound the horn. West Virginia polices when and how it sounds. A horn rated up to 150 dB is, by design, far louder than any factory horn. If it's wired or mounted as the vehicle's warning horn and you use it on a public road, I'd assume an officer can call it unreasonably loud and that the argument ends there.
Two more things I'd keep in mind:
- "Reasonably necessary" is a narrow window. A real warning to a driver drifting into your lane fits. Saluting your buddy at a Sheetz in Morgantown does not.
- Portable doesn't mean exempt. A battery horn fired from the cab or bed of a moving truck is a warning device being used on that vehicle. Being removable doesn't take it outside the statute.
What a horn ticket costs in West Virginia
§17C-15-33 doesn't carry its own penalty, so the general penalty in §17C-18-1 applies. Chapter 17C violations without a specific penalty are misdemeanors, and the scale escalates:
| Conviction | Maximum fine | Maximum jail |
|---|---|---|
| First | $100 | 10 days (fine or jail) |
| Second within one year | $200 | 20 days, or both |
| Third or subsequent | $500 | 6 months, or both |
Most first-time horn stops end with a warning or a small fine, but that third row is real, and it's a misdemeanor on your record either way. I'm a mechanic, not a lawyer. If you get cited, call a West Virginia attorney. For how other states price this, my state-by-state guide to train horn laws lays them side by side.
Disorderly conduct: the "asked to stop" trigger
The second statute to know is West Virginia's disorderly conduct law, §61-6-1b. It covers someone who, in a public place or a public parking area, disturbs the peace of others by "making of unreasonably loud noise that is intended to cause annoyance or alarm to another person," and who keeps doing it after a law-enforcement officer asks them to stop.
That last element is the one I want you to remember. The statute is built around persisting after a request to desist. If a deputy walks over at the river access lot and tells you to knock it off, you put the remote in your pocket. Keep blasting and you've handed them every element. The penalty is up to 24 hours in jail or a fine of not more than $100.
Note the "public parking area" piece: the code defines it as an area open to the public for parking, whether publicly or privately owned. Grocery store lots and boat ramp lots count. Your own driveway generally doesn't, but sound doesn't respect property lines, so point the trumpets away from neighbors.
Inspection stickers: every two years now, and what that means for a horn
If you last looked this up a few years ago, it changed. House Bill 2310 moved West Virginia from annual inspections to once every two years, effective January 1, 2024. Under §17C-16-4, the State Police superintendent requires every registered motor vehicle to be inspected "once every two years." The WV DMV says the sticker goes on the inside of the windshield, is good for 24 months, and costs a maximum of $19 for the full two-year period. Commercial vehicles under federal motor carrier rules still go annually, and Class A farm-use vehicles are only inspected if the owner asks.
Here's how I'd think about the horn at the inspection station:
- The factory horn is what gets checked. §17C-16-1 requires a vehicle's equipment to be "in good working order and adjustment," and §17C-15-33 requires a working horn audible at 200 feet. Keep the stock horn hooked up and working. Never replace it with a train horn.
- A portable horn sitting in the cab isn't vehicle equipment. A battery horn that isn't wired into the truck, stashed behind the seat, gives the inspector nothing to judge. I take mine out before inspection anyway. It's simpler.
- Hard-wired setups are where trouble lives. If you've tied a horn into the steering wheel button, an inspector can reasonably look at that as your warning device. A separate switch or a wireless remote, with the factory horn left alone, is the cleaner path.
I went deeper on what inspectors look at in will a train horn pass vehicle inspection. Neighboring Pennsylvania still runs annual safety inspections, so the drill is different there. See my Pennsylvania train horn guide.
How I'd run a portable horn in West Virginia
The reason I switched to battery horns is the same reason they make sense in West Virginia: nothing is plumbed into the truck. No tank, no compressor, no wiring to explain to an inspector. Snap in a pack, use it where it's appropriate, pull it off when you're done. The one I reach for is the Extreme Quad Train Horn for Milwaukee® 18v Battery: four powder-coated metal trumpets, rated up to 150 dB, runs on any Milwaukee® M18™ battery, with a standard wireless remote rated up to 160 ft and a long-range remote rated up to 2000 ft.
My rule set for the Mountain State:
- On a public road: treat it as off. Between "unreasonably loud or harsh" and "reasonably necessary," the statute leaves very little room for a train horn on the highway.
- On private ground: farms, hunting camps, ATV trails on your own land and private docks are where these horns earn their keep. If you ride the public trail systems, follow their posted rules and leave the horn off.
- Public lots: if an officer asks you to stop, stop. That request is the line in §61-6-1b.
- Ears: wear protection when you test. Loud is a feature, install it right.
If a smaller chord suits the farm or the boat better, the full lineup of train horns for Milwaukee® M18 batteries runs from dual-trumpet up to five-trumpet models on the same packs.

FAQ
Is it legal to own a train horn in West Virginia?
Yes. §17C-15-33 doesn't ban owning or carrying one. It requires a working horn audible from at least 200 feet, bans horns that emit an unreasonably loud or harsh sound, and limits horn use to when it's reasonably necessary for safe operation.
Is there a decibel limit for horns in West Virginia?
Not a number. The statute uses "unreasonably loud or harsh" instead, which leaves the call to the officer and the court. Cities can also have their own noise ordinances.
How often is vehicle inspection in West Virginia?
Every two years since January 1, 2024, under §17C-16-4. The sticker fee is capped at $19 for the two-year period, according to the WV DMV. Commercial vehicles subject to federal rules are still inspected annually.
Will a portable train horn fail my WV inspection?
A horn that isn't wired to the vehicle isn't part of the inspected equipment. What matters is that your factory horn works. Keep it connected and take the portable horn out before you go in.
What's the fine for an illegal horn in West Virginia?
Under §17C-18-1, up to $100 or 10 days in jail for a first conviction, rising to $500 and up to six months for a third. Disorderly conduct for unreasonably loud noise is a separate charge.
Bottom line: in West Virginia, own it, keep the factory horn working, use the train horn on private ground, and when someone with a badge asks you to stop, stop. — Cole
