If you have ever felt the urge to honk your car horn in frustration at another driver on the road, you will be glad you didn’t as it is illegal and can cost you a fine. Another example of illegal use is tooting your car horn to greet or say goodbye.
The Road Traffic Code 2000 (WA) says that a person shall not sound their car horn unless you are doing so to warn other road users or animals of the approach or position of the vehicle. Horns or warning devices are also the exception if they are being used as part of an anti theft device fitted to the vehicle.
In Western Australia, the current penalty is one penalty unit which is $50.00.
