Are Train Horns Legal in Arkansas? State Horn Law and Local Noise Ordinances

Arkansas is one of the easier states in the country to own a train horn, and the reason comes down to two things: a horn statute that never sets a decibel ceiling, and a state that stopped inspecting passenger vehicles back in 1997. Here is exactly where the lines are drawn.

The Short Answer: Legal to Own, Regulated by Sound and Use

No Arkansas statute bans buying, owning, mounting, or carrying a train horn. The state regulates the sound your horn makes and when you sound it on a public road. Three layers stack up, and the cheapest is the state layer:

• State equipment law (A.C.A. § 27-37-202(a)) — your vehicle must carry a working horn audible from at least 200 feet, and no horn "shall emit an unreasonably loud or harsh sound or a whistle."
• State device ban (A.C.A. § 27-37-202(b)) — no siren, whistle, or bell on a civilian vehicle.
• City noise ordinances — Little Rock, Fayetteville, and Fort Smith each write their own, and they are the ones with real money attached.

A first conviction under A.C.A. § 27-50-305 tops out at $100 or ten days. A Fayetteville noise conviction can run to $500, doubled for a repeat, plus $250 per day for a continuing violation. That gap tells you where to pay attention.

What Arkansas Code § 27-37-202 Actually Says

The operative language in subsection (a) is short. Every motor vehicle operated on 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 (200')," and "no horn or other warning device shall emit an unreasonably loud or harsh sound or a whistle." The driver "shall give audible warning with his or her horn" when reasonably necessary for safe operation, "but shall not otherwise use the horn when upon a public street or highway."

Three details matter. First, 200 feet is a floor, not a ceiling — Arkansas tells you how quiet your horn may be and never sets a maximum. Second, there is no decibel figure anywhere in the statute. Not 95 dB, not 110 dB, nothing; anyone quoting you an Arkansas dB cap for vehicle horns made it up. Third, the use restriction is scoped to "a public street or highway," the hinge the rest of this article turns on.

Subsection (b) is the clause people mistake for a train-horn ban: "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." A multi-trumpet air horn is none of those three. It makes a chord, not a siren sweep, not a steam-whistle shriek, not a bell strike. The same subsection carves out a commercial-vehicle theft alarm "so arranged that it cannot be used by the driver as an ordinary warning signal," and requires emergency vehicles to run a siren or bell audible at 500 feet — carve-outs that only make sense if (b) targets devices imitating emergency equipment. Arkansas shares this drafting with its neighbors almost word for word; compare the breakdowns for Missouri and Oklahoma.

No Safety Inspection Since 1997 — and What Replaced It

Arkansas ended its periodic safety inspection program with Act 974 of 1997, and the state has never run a mandatory emissions program for passenger cars. No annual sticker, no lane appointment, no technician paid to walk around your truck with a checklist. For anyone adding equipment, that removes the biggest scheduled risk.

What replaced it is roadside discretion. A.C.A. § 27-32-101 still requires equipment on a registered vehicle to be "in good working order and adjustment as required for the vehicle's safe operation," and gives any officer with reason to believe a vehicle has safety defects cause to stop and inspect it. A.C.A. § 27-37-101 makes it a misdemeanor to drive on a highway a vehicle in unsafe condition or not equipped as the chapter requires.

The practical difference is timing. In an inspection state, a modified vehicle has an annual appointment with someone paid to find non-compliant equipment — we covered that in our guide to train horns and inspection failures. In Arkansas, enforcement is behavior-driven: an officer has to hear you do something unreasonable. Nobody flags your horn on paper in March.

Keep the Factory Horn Connected — It Costs You Nothing

Read 27-37-202(a) again. It is an affirmative equipment requirement: your vehicle shall be equipped with a working horn audible at 200 feet. Nothing limits you to one device. The failure Arkansas actually punishes is a vehicle with no working horn — exactly what happens when somebody rips out the OEM unit to make room for an air setup.

A battery-powered horn sidesteps the whole argument, because it is never wired into the vehicle. No cut wire, no spliced horn relay, no tapped compressor circuit — it runs off a cordless tool pack and lifts off the truck when you are done. The Extreme Series Train Horn for Milwaukee® 18v Battery is the clearest example: click on any Milwaukee® M18™ pack you already own, pull the trigger or hit the wireless remote from up to 2,000 feet, and your factory horn stays exactly where the statute wants it.

Arkansas City Noise Rules: Little Rock, Fayetteville, Fort Smith

State law gives you a vague standard. Cities give you numbers — except Little Rock, which pointedly does not.

Zone	Fayetteville — Ch. 96 Table 1	Fort Smith — Sec. 16-45 Table 1
Residential	60 dB(A) day / 55 dB(A) night	60 dB(A) day / 55 dB(A) night
Commercial	75 dB(A) / 70 dB(A)	75 dB(A) / 70 dB(A)
Industrial	80 dB(A) / 75 dB(A)	80 dB(A) / 75 dB(A)
Night hours	11 p.m.–7 a.m.	11:01 p.m.–6:59 a.m.
Little Rock	No decibel table at all — Sec. 18-52(b)(1) restricts horn use to danger signals

Little Rock is the strictest of the three on horns, and it does it without a meter. Sec. 18-52(b)(1) makes it unlawful to sound any horn or signal device on a vehicle "while not in motion, except as a danger signal if another vehicle is approaching apparently out of control," and while in motion "only as a danger signal after or as brakes are being applied." The same clause outlaws "any unreasonably loud or harsh sound" from such a device and sounding it "for an unnecessary and unreasonable period of time." Read literally, a celebratory blast from a parked truck is the textbook violation, and no decibel reading is needed to write it.

Fayetteville gives you both a table and a horn rule. Ch. 96.05(C) says no person shall sound any horn or auditory signaling device on a motor vehicle on a public right-of-way or public place "except as a warning of danger" — Little Rock's substance, plainly written. Table 1 is measured at the property line of the parcel the sound comes from, and under 96.04(D) a transient source gets 20 dB of headroom above it. Penalties under 96.99 reach $500, doubled for each repetition, plus $250 per day for a continuing violation.

Fort Smith is the loosest of the three, deliberately. Ordinance No. 92-09, adopted 10/06/2009, repealed the city's old standalone sections on motor vehicles, engine exhausts, and horn sounding, leaving the general noise-disturbance rule in Sec. 16-42 and the decibel table in Sec. 16-45. Sec. 16-42(b)(1) then exempts outright "the emission of sound for the purpose of alerting persons to the existence of an emergency or as a warning signal." A horn used as a warning signal in Fort Smith is not merely defensible — it is a listed exception.

Where Arkansas Owners Can Actually Let It Rip

Re-read the use clause once more: the driver "shall not otherwise use the horn when upon a public street or highway." Off a public road, 27-37-202's use restriction has nothing to say, and what is left is the local noise ordinance and ordinary courtesy toward your neighbors.

• Private property and farmland — your own acreage, though Fayetteville and Fort Smith measure at the property boundary, not the source.
• Pasture and livestock work — moving cattle, pushing deer off a field edge, signaling across a hay meadow.
• Off-road and UTV trails — not a public street, not a highway.
• Lakes and boat ramps — a portable horn is a legitimate marine sound signal and comes off the boat with you.
• Tailgates and race day — the horn is not attached to a vehicle at all.

That portability is the structural argument for a battery horn in a no-inspection state. A hardwired tank-and-compressor setup lives on the truck permanently, so every traffic stop sees it and 27-32-101 gives the officer a reason to look. A pack-powered horn goes back in the toolbox when you are done. Our state-by-state overview maps the same question nationally.

FAQ

Are train horns illegal in Arkansas?

No. No Arkansas statute prohibits the purchase, ownership, or installation of a train horn. A.C.A. § 27-37-202 regulates the sound your horn makes and when you sound it on a public street, and its device ban covers sirens, whistles, and bells — not multi-trumpet air horns.

Will a train horn make my vehicle fail inspection in Arkansas?

Arkansas has no periodic safety inspection and no mandatory emissions testing for passenger vehicles; the program ended with Act 974 of 1997. What remains is a roadside stop under A.C.A. § 27-32-101, which an officer initiates on reasonable belief of a safety defect — not a scheduled appointment.

Do I have to disconnect my factory horn?

No, and you should not. A.C.A. § 27-37-202(a) requires every vehicle on a highway to carry a horn in good working order audible at 200 feet, and nothing limits you to one device. A battery horn is not wired into the vehicle at all, so there is nothing to disconnect in the first place.

What does an Arkansas horn ticket cost?

A first conviction under A.C.A. § 27-50-305 carries not more than $100 or ten days, rising to $200 for a second conviction within a year and $500 for a third. Municipal noise charges are separate — Fayetteville's Ch. 96.99 allows up to $500, doubled for a repeat.

Do railroad quiet zones in Arkansas apply to my horn?

No. Quiet zones are a federal railroad program. The FRA Train Horn Rule at 49 CFR Part 222 governs when locomotive engineers sound the horn at public grade crossings — 15 to 20 seconds in advance — and 49 CFR 229.129 sets locomotive horn output between 96 and 110 dB(A) measured 100 feet ahead of the engine. None of that reaches a horn on a pickup. Your rules are A.C.A. § 27-37-202 and your city code.
