The Mississippi $1.78M Train Horn Verdict — Kelly v. Garland Explained
May 2024 Hinds County jury awarded $1,787,597 against a trucker who sounded a 145 dB train horn 10 feet from a person. What it means for truck owners.
In May 2024, a Hinds County (Mississippi) jury returned a verdict for $1,787,597 in a civil negligence case against a trucker whose 145 dB aftermarket train horn caused permanent hearing damage to a plaintiff standing roughly 10 feet from the horn. The case — Kelly v. Garland — is the first widely-publicized civil judgment in the train horn aftermarket and the most-cited case for what truck owners should expect from worst-case liability.
What happened
Per Land Line and Overdrive coverage:
- A truck operator activated an aftermarket train horn while another person was approximately 10 feet from the trumpets
- The horn produced an estimated 145 dB at the source
- The plaintiff suffered permanent hearing damage (tinnitus + threshold shift)
- A Mississippi civil jury awarded $1,787,597 in damages
- The award covered medical costs, pain and suffering, lost wages, and punitive damages
This was a civil tort case, not a criminal prosecution. The plaintiff sued the truck operator personally for the hearing injury.
Why the verdict matters
Three things about Kelly v. Garland set the practical liability ceiling for aftermarket train horn use:
1. No specific train-horn statute was needed
Mississippi (like every state we’ve researched) has a vehicle code provision against “unreasonably loud or harsh” horns, but no numeric dB cap and no explicit ban on aftermarket train horns. The case didn’t require a train-horn-specific statute — standard civil negligence theory was sufficient. Reasonably foreseeable injury from intentionally directing a 145 dB sound source at a person within hearing-damage range.
This means similar cases can succeed in any state without the state needing to pass new legislation. The legal framework already exists.
2. The 145 dB figure is in the consumer aftermarket range
Court coverage doesn’t disclose the specific horn model, but 145 dB at 3 ft is roughly the realistic peak SPL of a HornBlasters Shocker XL (147.7 dB DJD-verified) or a high-end air kit at typical operating pressure. The horn wasn’t a refurbished K5LA or some exotic equipment — it was within the verified consumer-market SPL range.
Anyone with a $799.99 HornBlasters Conductor’s Special 232 install is operating at this same SPL. Same physical capability, same potential liability if used recklessly.
3. The 10-foot distance is realistic
Most truck-horn-related complaints cite distances of 10-30 feet (parking lot, gas station, drive-thru). The 10-foot distance in Kelly v. Garland isn’t an outlier — it’s the typical close-range scenario where someone “lays on the horn” at an annoyance.
OSHA permissible exposure for a single 145 dB blast is 0 seconds — instantaneous damage threshold is 130 dB, immediate-injury threshold is 140 dB. At 10 feet from a 145 dB-at-3-ft horn, attenuation drops to roughly 135 dB at the listener — still above immediate damage threshold for unprotected hearing.
What truck owners should take away
Five practical implications:
1. The horn install itself is legal in most states
You’re not at risk of civil liability for installing or owning an aftermarket train horn. The vehicle codes in every state we’ve researched permit aftermarket horn installs as long as they’re not “unreasonably loud or harsh” (see /guides/are-train-horns-legal-on-trucks/ for state-by-state breakdown).
2. The risk is in how you use it
The civil liability arises from intentionally sounding the horn at close range to a person. A horn used at appropriate distances (highway warning, traffic horn use, train-crossing-equivalent applications) doesn’t trigger this kind of lawsuit.
3. Insurance coverage is uncertain
Auto insurance liability coverage typically applies to negligent causing of harm. Many policies have intentional-acts exclusions and noise-pollution exclusions that could leave the truck owner personally liable for a Kelly v. Garland-class verdict. Check your auto policy specifically.
4. Don’t fire the horn within ~25 feet of pedestrians
The practical install rule from this case: never sound your train horn with someone within ~25 feet of the trumpets. SPL at 25 feet from a 147 dB-at-3-ft horn is roughly 128 dB — uncomfortable but not immediately damaging in single-burst exposure. Within 10-15 feet, hearing damage becomes likely.
5. Training in install/install-test protocol
The same rules apply during install testing. Never test-fire with anyone within 10 feet, ears unprotected. Wear hearing protection yourself during install. Test-fire pointing trumpets away from buildings or other people. This is not paranoia — it’s OSHA-aligned safe practice that became a $1.78M verdict in Kelly v. Garland because it wasn’t followed.
How big is $1.78M as a verdict?
Mississippi has a $1M cap on non-economic damages (pain and suffering) in civil cases — the verdict reduces by tort cap to a maximum of around $1M after the cap is applied. So the practical post-cap damages exposure is:
- Medical expenses (uncapped): ~$200K-$500K typical for permanent hearing loss
- Lost wages (uncapped): varies by plaintiff
- Pain and suffering (capped at ~$1M)
- Punitive damages (rare, varies)
Total practical exposure for a truck owner sued for this kind of injury: $500K-$1.5M after tort cap. Not millions of millions, but six-figure ruinous to most truck owners’ personal finances.

Related case considerations
There are no widely-publicized similar verdicts before or after Kelly v. Garland that we’ve identified — this case is unusual primarily for the size of the award and the public coverage. But the legal framework that supported the verdict (general civil negligence) exists in every state, and the SPL physics that caused the injury (145 dB at close range exceeds immediate-damage threshold) applies to every consumer aftermarket train horn.
The verdict is recent enough that we should expect similar cases to surface in the next 5-10 years as more aftermarket train horns get installed and the case law develops. Truck owners installing in 2026 should treat Kelly v. Garland as the practical liability baseline.
What we don’t know
Several things about the case aren’t publicly disclosed:
- The specific horn make/model the trucker used
- Whether the horn was installed legally or with any compliance issues
- The relationship between the trucker and plaintiff (acquaintance, stranger, dispute escalation)
- Whether the trucker’s auto insurance covered the judgment or excluded it under intentional-acts language
- Whether the trucker has appealed (typical in awards above $1M)
These details would affect the practical lesson but aren’t disclosed in public coverage. The takeaway remains: don’t sound a 145+ dB horn at close range to a person.
The takeaway
If you’re considering a train horn install, the install itself isn’t the legal risk — it’s how you use it after install. Treat the horn like a tool that can permanently injure someone within 25 feet of the trumpets. Respect that distance. Don’t lay on the horn at someone close as an annoyance or threat. Wear hearing protection during install testing. The Kelly v. Garland verdict is what happens when those rules aren’t followed.

FAQ — Kelly v. Garland and liability.
- 01 What was the Kelly v. Garland Mississippi train horn verdict?
- May 2024 Hinds County (Mississippi) civil jury verdict awarding $1,787,597 to a plaintiff whose hearing was permanently damaged by a 145 dB aftermarket train horn used approximately 10 feet from him. The case was civil tort negligence, not criminal prosecution. Plaintiff sued the truck operator personally for the hearing injury. Mississippi tort cap on non-economic damages reduces practical exposure to ~$500K-$1.5M post-cap — still six-figure ruinous to most truck owners' personal finances.
- 02 Was the train horn in Kelly v. Garland illegal?
- No. The horn was an aftermarket train horn within the consumer-aftermarket SPL range (similar to HornBlasters Shocker XL at 147.7 dB at 3 ft DJD-verified). Mississippi vehicle code prohibits 'unreasonably loud or harsh' horns but doesn't ban aftermarket installs. The verdict was on civil negligence theory: foreseeable injury from intentionally directing 145 dB sound at a person within hearing-damage range. The case didn't require a train-horn-specific statute — standard civil negligence law was sufficient.
- 03 Could a similar verdict happen in any state?
- Yes. The legal framework that supported Kelly v. Garland (general civil negligence theory) exists in every US state. The SPL physics that caused the injury (145 dB at close range exceeds OSHA immediate-damage threshold) applies to every consumer aftermarket train horn. Mississippi's tort cap reduced practical exposure; states without similar caps could see higher post-cap awards. Truck owners installing in 2026+ should treat Kelly v. Garland as the practical liability baseline regardless of state.
- 04 Will my auto insurance cover a train horn lawsuit?
- Maybe not. Auto insurance liability coverage typically applies to negligent causing of harm. Many policies have intentional-acts exclusions and noise-pollution exclusions that could leave the truck owner personally liable for a Kelly v. Garland-class verdict. Check your auto policy specifically for: intentional-acts exclusions, noise-pollution exclusions, modified-vehicle / aftermarket-modification exclusions. Some insurers raise premiums or require disclosure for aftermarket horn installs. Get the coverage detail in writing before installing.
- 05 How close is too close to fire a train horn at someone?
- OSHA permissible exposure for a single 145 dB blast is 0 seconds (immediate-damage threshold is 140 dB). At 50 feet from a 147 dB-at-3-ft horn, attenuation drops to roughly 128 dB at the listener — uncomfortable but not immediately damaging. Within 10-15 feet, hearing damage becomes likely on a single exposure. Practical install rule: never sound your train horn with someone within 25 feet of the trumpets, ears unprotected. The Kelly v. Garland 10-foot distance was within the immediate-damage range.
- 06 Should I still install a train horn after the Mississippi verdict?
- The install itself isn't the legal risk — it's how you use it. Possessing and installing an aftermarket train horn is legal in 49 of 50 states. The civil liability arises from intentionally sounding the horn at close range to a person. A horn used at appropriate distances (highway warning, traffic signaling) doesn't trigger this kind of lawsuit. Practical rules: never honk at pedestrians at close range, wear hearing protection during install testing, and respect the 25-foot exclusion zone around the trumpets. With those rules followed, the install is functionally similar to owning any other loud vehicle accessory.
