Using your car’s horn may seem trivial, but in Australia, the rules are clear and the penalties for misuse can be hefty.
Across the country, regulations define when and how drivers can use their vehicle’s horn, emphasizing its role as a safety device rather than a tool for venting frustration or casual communication.
When It’s Okay to Honk
The legal use of a car horn is uniform across all states and territories. Drivers are permitted to use their horn:
To warn others about the position of their vehicle.
To alert road users or animals of an approaching vehicle.
As part of anti-theft or alcohol interlock devices.
Horns are meant to enhance safety, not for casual greetings or emotional expressions.
When Honking Crosses the Line
Using a horn becomes an offence if it’s employed:
To intimidate or scare others, including cyclists, pedestrians, or horseback riders.
Repeatedly, out of frustration or impatience.
To greet, thank, or bid farewell to someone.
Misusing a car horn can be distracting, distressing, and even dangerous to other road users.
The Fines You Could Face
Penalties for improper horn use vary by state, with fines ranging from $50 in Western Australia to $410 in New South Wales (NSW), the highest in the country.
NSW: Fines start at $410.
Victoria: Drivers face a penalty unit fine of $197.59.
Queensland: A $96 fine applies.
South Australia: Misuse can cost $323.
ACT: Fines reach $272, with up to 20 penalty units possible.
Northern Territory: Fines start at $200.
Tasmania: Fines of $146.25 apply.
Western Australia: A $50 fine is the lowest in Australia.
Driving Without a Horn
Interestingly, not having a functioning horn is also illegal. Every roadworthy vehicle in Australia must be fitted with a device that provides an audible warning. However, the sound cannot mimic sirens, whistles, or bells.
