It’s a fact: your vehicle must have a horn that can be heard from a distance, If it doesn’t, then you’re at risk of getting fined and having your car towed away to the nearest garage for inspection. This is because emergency vehicles need clear access to roads without any obstructions so they can do their job effectively in an emergency situation. So how loud does your car horn have to be? The answer might surprise you!
To be able to hear your horn from a distance of 100 ft: Your car’s horn must be no less than 96 dBA.You have to press the button for at least one second or more if you’re using a silenced vehicle so that it can not emit any sound louder than 85 decibels. If your vehicle is in motion and has an electric starter, your device will flash while sounding its alarm. Any other time when your engine is running with the key turned on but without starting the motor, this flashing warning signal should also come on automatically in order for people around you to know about your presence.
You can’t just beep your horn as a joke to make the person in front of you move. Doing so, could cause them to panic and they might crash into something or someone.’
Your car’s alarm should be no less than 120 dBC with an 85 decibel upper limit for nonemergency situations.
The emergency situation is different: it requires at least 160 dB if your vehicle has been involved in a collision that caused injury/death (or there are indications that one may have occurred) whereupon law enforcement would need access through use of the vehicle’s keyless remote entry system.’

The National Highway Traffic Safety Administration (NHTSA) says your vehicle’s “horn shall have an intensity level of not less than 120 dBC.” What this means is that you are authorized to use it as long as its volume exceeds 85dB during normal driving conditions or if there has been a collision where someone was seriously injured or killed.
