Australia has clear rules about when a car horn can and cannot be used.
Unnecessarily beeping one’s car horn is considered a traffic offence, for which divers can cop a fine ranging from $50 to more than $400, depending on where you live.
In addition, failure to pay an outstanding fine can also lead to additional penalties.
Across all states and territories, the proper, legal use of a vehicle’s horn is defined in their road rules legislation, and drivers are advised to use their horns courteously.
When can I use a vehicle’s horn?
All state and territory legislation advise using the horn or any other warning device only:
- to warn other road users about the position of your vehicle
- to warn others that you are approaching
- to warn animals to get off the road
- if it’s part of an anti-theft or alcohol interlock device
When can I not use the horn?
The use of a horn or similar warning device is considered unnecessary if:
- it is used to scare or intimidate other road users, particularly bicycle riders, pedestrians and horseriders
- done repeatedly out of frustration or inconvenience as it can be distracting and distressing to other drivers, and
- to greet, thank or see off people on the road or roadside
What are the penalties for the misuse of a horn?
In NSW, offenders can be fined $410 – the highest penalty for this offence across Australia.
An additional penalty is levied in extreme cases such as when the offender doesn’t pay outstanding fines, and has to be produced in court.
In such cases, a maximum of 20 penalty units can also be levied, each at $110.

Can I drive without a horn?
While the improper use of a horn is a punishable offence, it’s also illegal to drive without a horn fitted into your vehicle. A working horn makes a vehicle roadworthy.
Across all states and territories, the rule is that all motor vehicles must be fitted with one or more devices that can give a sufficient audible warning to other road users of the approach or position of the vehicle.
The device shouldn’t make a sound like a siren, bell, exhaust whistle, compression whistle or repeater horn.
