What is the Law with Car Horns in the US?

Best Car Horns 2019 – The Ultimate Ratings & Reviews Buyer's Guide

Car horns today can be outrageous. Take your pick from bells to catcalls, train whistles, to full orchestral arrangements. Pay the price, and you can have it. This is not to say that the government will allow it, however, but even this varies from state to state.

Let’s take one type of horn, the train whistle, and look at how it varies from state to state in just a few jurisdictions.

 Most of the areas of the country have one primary rule with regards to car horns: they can not emit an unreasonably loud or harsh sound . This is usually understood to be louder than 100 to 110 decibels. This is compared to a train horn which generally operates at 130 to 150 decibels. A few states and their regulations are listed below:

In California, a train horn can be mounted on a car but not used. On a semi-truck, it is allowed if it is attached to the air brake system, powered by the air from the brake system, complies with FMVSS standards 121 and 106, and has the appropriate certifications. If you are found to have violated those terms, you can receive a minimum $108 fine if there are no other violations or citations on your CDL.

In Texas, an annual inspection is required for all motor vehicles. If during the inspection, a train horn is found to be hooked up and able to be used as a regular warning, the vehicle will fail the inspection. It can, however, be hooked up on a truck as part of a commercial vehicle theft alarm. If the train horn is hooked up and used, you can recieve a citation for noise pollution and be held liable for any resulting accidents.

In Georgia the vehicle modification laws state that one could be used as part of an alarm system but not hooked up to be used as a regular warning system. Violation of this could result in a possible citation or moving violation.

Virginia law states that all warning devices must be approved by the Superintendent. A train horn could be used as part of an alarm or anti-theft system. However, it must be installed so that it cannot be used when the vehicle is in motion.

In most other states the only types of vehicles allowed to have any type of air horn are emergency vehicles.

To check the specifics in your area, check your state’s DMV or BMV website. Check laws specifically for horns, but also for vehicle modifications. A train horn would require an air compression system to operate, making it subject to the modification laws. Not all states have a law specifically prohibiting the horn being mounted on a vehicle, only the use of it as a standard warning device.

Car Horn Etiquette: The Dos and Don’ts of Honking Your Horn

When used responsibly, car horns should notify drivers of danger, helping to prevent accidents and keep everyone on the road safer.

But that’s only when used appropriately.

When used “inappropriately” or incessantly , car horns are not only irritating, they can be distracting and dangerous as well. For example, if you’re busy honking at a driver who’s moving too slowly, you’re probably not paying close attention to the road. Not to mention the fact that the sound of a car horn can be jarring and you don’t want to unnecessarily disrupt anybody operating a 5,000-lb metal box on wheels, unless it’s to avoid some sort of danger.

Spoiler title
  • Do use your car horn to let a driver know they’re fading into your lane.
  • Don’t “lay” on the horn or accompany that honk with an angry gesture. Safety should always be top priority, and letting your emotions take the wheel can result in road rage.
  • Do give a quick beep if you see a pedestrian unknowingly walking into a dangerous traffic situation. For instance, if a car’s reversing out of a parking spot and a pedestrian’s walking straight into their path, it’s ok to give a quick honk to keep both parties safe.
  • Don’t honk at pedestrians who are lollygagging while crossing the street. Yes, it can be annoying. And yes, you might be 5 hours into a car ride where your copilot has insisted on belting out an endless stream of show tunes. But still, don’t do it. As the California Department of Motor Vehicles states, drivers should not use their horn “to honk at pedestrians, bicyclists, or motorcyclists unless necessary to avoid a collision. Remember that your horn sounds much louder outside a vehicle.”
  • Do be a patient and considerate driver. Honking your horn in a bumper-to-bumper traffic jam won’t do you much good anyway. Your car horn should be used as a tool to avoid danger, not express anger (get a stress ball for that).
  • Don’t immediately start honking if the car in front of you doesn’t accelerate as soon as the light turns green. You might not be able to see what’s happening on the road ahead and you might startle them and cause an accident.
  • Do know your local car horn laws. In New York City, for example, drivers who use their horn in any situation that’s not an “emergency” can be cited and fined $350. While these tickets aren’t widely issued (which explains the endless honking in Times Square), it’s good to know (and abide by) your local driving laws.

How To Deal With Road Rage – Use your horn only when necessary

Best Car Horns 2019 – The Ultimate Ratings & Reviews Buyer's Guide

Most of us spend an hour or two in the car daily, and nothing is more frustrating than spending that time surrounded by idiot drivers. The fact of the matter is, all the swearing, horn-honking, name calling and aggressive tailgating in the world won’t make you feel better nor make the clueless person you’re stuck behind any better of a driver. Road rage only leads to trouble. Here are a few tips for you to consider next time you feel like running some jerk off the road.

Pick your tunes wisely

You want to create the most peaceful atmosphere possible while in your car. Choose a genre that helps you keep your zen. For some people Heavy metal music is cathartic, but for others, it’s enraging. Use CD’s, cassettes (if your ride predates The Rolling Stones) or your iPod- not through headphones- and avoid Rush Limbaugh on the radio if possible. There’s nothing worse than being stuck in traffic listening to that fat blow-hard telling us how the current administration is ruining America. Which brings me to my next point…

Avoid driving during rush hour at all costs

Plan your travel time for earlier or later and get to know your city’s busiest commuting times, it’s different everywhere, but most places have rush hours in the morning from around 7 am to 9 am then again in the early evening from about 4 pm to 6 pm. If your whole day depends on traveling through these times then you should look into alternative modes of transportation, either bus or train, or carpooling as an option, it’s always a good idea to have other people around you to defuse the tension.

Take back roads to avoid traffic

On your way to and fro, check for alternative routes through back roads. Seriously, there is nothing more peaceful than a drive through the country. The roads less traveled are also useful for avoiding highway construction projects that could lead to major delays.

Make sure you don’t have to go to the bathroom

It may seem juvenile but make a quick trip to John before getting behind the wheel. My most vulgar, curse-ridden-rants came from an overly full bladder. “Having to go” leads to erratic and restless driving more so than anything else.

Leave with plenty of time to get to your destination

Give yourself a half hour buffer to account for traffic or any other unforeseen circumstances that could lead to a delay in your travel. Being late to work is a trigger for road rage.

When driving we’re not all going to the same place at the same time, but it is imperative to be forgiving of poor drivers or road conditions, life happens! We have all heard the stories and seen the YouTube videos of people yelling at each other and even getting in fistfights over serendipitous lane merges or other careless driving maneuvers. Heed this simple advice, and you won’t be the next viral road raging sensation, I assure you.

Air Horn FAQ

What are the advantages of owning a train horn?

Primarily, a train horn signaling system will increase your chance of being heard in an emergency situation. Often, in the roar of high speed big rigs on the interstate, a stock horn may not be heard. Your new air horn system will be heeded in all situations, from a child about to run in the street to retrieve a ball to an approaching car about to drift into your lane.
Oh yeah, did we mention that they are a lot of fun?

I'm concerned about installation. Can I do this myself?

Most car horn kits are easy to install. The concept is simple–basically, the compressor feeds the tank which feeds the horn. Components are powered by 12V standard DC vehicle power. Everything that you need including air hose, fittings and wiring is included in the kit. Still, figure at least a couple hours or more depending on the sophistication of your install.

Follow the directions closely for a good installation. Don’t forget to use thread tape on all air ports for an air tight install. Don’t leave out any components. We can’t be responsible if components fail due to an improper install or inappropriate operation.

Your installation will go quicker with a knowledgeable friend helping out. Many users feel more comfortable hiring a garage to do the work. If you want to go this route, and you have no preference, we recommend contacting a business that specializes in alarm/remote starter/audio installations as they are very familiar with 12V DC wire-ups and running wires.

There are several online step by step video installations you can so you will feel confident that you can install the kit yourself after watching.

What's the difference between authentic car horns and kits and others cheap replica horns I see on the Internet?

Cheap kits are sold without regard to quality components.  Expect two liter or smaller tanks (good for just a couple toots), cheap compressors that work slowly and noisily and inefficient plastic horns (even chrome ones). You get what you pay for.

Why don't I see db ratings for some horn kits?

Like watts for amplifiers, db ratings can be misleading. Under what circumstances were the decibels determined? How far away from the horn was the measurement taken? What device was used to measure? When was it last calibrated. Train horns are very loud.

How much is a train horn for a car?

The cost of train horns depends on some factors. If you buy a basic kit that doesn’t have an air horn compressor and air hoses, you can find a decent one for less than $100. In fact, train horn kits are starting as low as $20. But like anything else, you get what you pay for.

How much does it cost to replace a horn in a car?

Know what price you should pay to get your vehicle fixed. The average cost for a horn replacement is between $105 and $171. Labor costs are estimated between $35 and $100 while parts are priced between $70 and $71. Estimate does not include taxes and fees.

Why is my car horn not working?

But an inoperative horn can also be caused by a bad horn switch in your steering wheel, a broken “clock spring” under the steering wheel, a bum horn relay, a broken wire or a corroded ground. Here’s how to check the most likely suspects. Start with the fuse. Refer to the owner’s manual for its location.

What is a horn switch?

The horn switch is a first buzzer; when pressed, a complete circuit directs power to the horn itself. The horn is a straightforward device, working off a solenoid that has the negative side grounded to the frame of your car. When a positive voltage is distributed, the solenoid pulls it in, and the horn sounds.

What is a safe decibel level?

With extended exposure, noises that reach a decibel level of 85 can cause permanent damage to the hair cells in the inner ear, leading to hearing loss. Many common sounds may be louder than you think. A typical conversation occurs at 60 dB – not loud enough to cause damage.

Why the different size tanks?

The larger the tank, the more blasts between re-fills. You’ll have to balance tank size with the space you have in your vehicle.

What is the best way to install my air horns?

There is no “perfect” answer to that question. Your installation needs to be thought out as to where you want your horns, your compressor and your air tank mounted. Something that is especially important, though: No matter where you mount your horns, keep the air solenoid as close to the horns as possible. This will eliminate any delay in sounding the horns if you keep the solenoid close.

Conclusion

Yes, it may look like a very simple thing. However, a car horn plays a critical factor in the vehicle’s operating. It helps alert or warn other motorists or roads users and is also a legal requirement. A poorly-made horn is as bad as not having one in the first place. It won’t be audible, may be too loud, or operates erratically. In the above review, we have briefly examined the top 8 car horns on the market. We looked at the key things which include size, material, design, compatibility, sound, installation ease, installation space, and price. You are thus guaranteed of a properly functioning unit and maximum satisfaction.

Always think first and foremost about whether it will alert other drivers to your presence.
