When is it appropriate to use your horn?
Generally, you should only honk the horn when reasonably necessary to insure safe driving.
Here’s some advice from the California Department of Motor Vehicles that you may want to pass along to fleet drivers:
Horn, Headlights, and Emergency Signals
Use Your Horn
- Only when necessary, to avoid collisions.
- To try to get “eye contact” with other drivers. You may tap your horn to alert another driver who might turn in front of you and cause a collision.
- On narrow mountain roads, where you cannot see at least 200 feet ahead of your vehicle.
Don’t Use Your Horn
- If a driver or bicyclist is going slowly, and you want him or her to drive faster or get out of your way. The driver or bicyclist may not be able to safely go faster, due to illness, being lost, intoxication, or having mechanical problems with the vehicle.
- To alert other drivers that they made a mistake. Your honking may cause them to make more mistakes or to become angry and retaliate.
- Because you may be angry or upset.
- To honk at pedestrians, bicyclists, or motorcyclists unless necessary to avoid a collision. Remember that your horn sounds much louder outside a vehicle.
Use Your Headlights
- When it is cloudy, raining, snowing, or foggy. If weather conditions require you to use your windshield wipers, you must turn on your low-beam headlights — it’s the law.
- On frosty mornings, when other drivers’ windows may be icy or “fogged.”
- Any time conditions (clouds, rain, snow, dust, smoke, fog, etc.) prevent you from seeing other vehicles. Other drivers may have trouble seeing you, too.
- On small country or mountain roads, even on sunny days. This helps other drivers see you and may help you avoid a head-on crash.
- When necessary to get another driver’s attention.
Use Your Emergency Signals
If you can see a collision ahead, warn the drivers behind you by turning on your emergency flashers or tapping your brake pedal quickly 3 or 4 times. You can also use the hand signal when slowing and stopping.
Never stop on the road unless necessary for safety or to obey a law. If you need to stop, start braking early as a signal to the cars behind you. If your vehicle breaks down on the road, make sure that other drivers can see it. If you experience vehicle trouble and need to stop, follow these rules:
- Pull off the road away from all traffic, if possible.
- If you cannot get completely off the road, stop where people can see you and your vehicle from behind. Do not stop just over a hill or just around a curve.
- Turn on your emergency flashers if you are not moving. If your vehicle doesn’t have emergency flashers, turn signals may be used instead.
- If it is safe, lift the hood to signal an emergency.
- Give other drivers plenty of warning. Place emergency flares or triangles 200–300 feet behind the vehicle. This allows other drivers time to change lanes, if necessary. Be very careful when using flares. They may cause fires, especially when used near flammable liquids.
- If you do not have emergency flares, follow the rules listed above and stay in your vehicle until help arrives. Be careful for your safety and stay off the road.
REMEMBER: Do not try to change a tire if it means you have to stand in a traffic lane.
Car horns: Noisy nuisance or driving must?
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.
Honking is sometimes against the law
In some cities, honking your horn between certain hours is against the law. I don’t think anyone will miss the neighborhood carpool mom honking at 6:00 a.m. to get the kids outside. You don’t have to worry about breaking the law if you use your horn only when absolutely necessary. Not wanting to get out of the car and ring the doorbell is not grounds for using your horn.
