Beware: Little-known road rule leads to hefty fines and imprisonment

Navigating the roads can be a tricky business, and for drivers, staying up-to-date with the ever-evolving road rules is crucial.

But there's one little-known law that could catch many of us off guard, and it concerns something as seemingly harmless as using your car horn.

A prominent Australian solicitor has recently highlighted a road rule that many drivers might not be aware of, which could lead to hefty fines or even imprisonment.


The law states that drivers should only use their car horns for specific purposes: to warn other drivers, to alert animals to their vehicle's approach, or as part of an anti-theft or alcohol interlock device.

Any other use could be considered inappropriate and, therefore, an offence.

‘Whether it’s beeping to greet friends or family members or out of frustration of others’ driving, honking your horn inappropriately is an offence,’ Sydney lawyer Avinash Singh shared.

‘No matter what state you’re driving in, a vehicle's horn can only be used to warn other drivers or alert animals about the approach or position of their vehicle.’

‘The only exception to this is if the horn is being used as part of an anti-theft device or an alcohol interlock. Drivers caught using their horn in situations outside of these could face possible imprisonment and fines of over $3,000, depending on which state they reside.'


Penalties for using car horns vary by state: New South Wales has a maximum penalty of 20 penalty units, currently $2,200; Victoria imposes a fine of 1 penalty unit, valued at $197.59.

Queensland also has a maximum of 20 penalty units, amounting to $3,226; Western Australia fines one penalty unit, currently $50.

South Australia imposes a $323 fine; the Northern Territory imposes up to 20 penalty units ($3,700) or six months imprisonment; Tasmania's fine is $146.25; and the Australian Capital Territory issues a $264 infringement penalty, with a maximum of 20 penalty units ($3,200).

Given the significant variations and strict enforcement, it's crucial to be aware of and adhere to local regulations regarding car horn use.


A sobering statistic underscores the urgency of adhering to road rules: Australia's road network recorded its deadliest six months in the first half of 2024, the worst in over 13 years.

The Australian Automobile Association's report showed a 7.3 per cent increase in deaths from 2022 to 2023, with 1,266 people losing their lives last year.

The second half of 2023 was particularly grim, marking the deadliest consecutive quarters since 2010, with 677 road deaths.

Significant increases in New South Wales, Victoria, and South Australia drove this spike in the national road toll.


In related news, the legality of flashing headlights to warn other drivers about speed cameras or other hazards differs across Australian states and territories.

In New South Wales, while no specific law prohibits flashing headlights, drivers can face fines for dazzling other road users or using high beams within 200 metres of another vehicle. Read more about this news here.

If for some reason I would need to use the horn on my car, if I am avoiding someone who hasn't noticed I am on the road or trying to avoid them whilst watching the cars behind me. I don't have time to even think about using the horn. Good to know however that we are actually allowed to use the horn to prevent an accident if we have time to use it.
 
I have known this rule since 1980 when I got my licence.
Known since 1974. Other ppl need to SLEEP!!! Being woken by some ratbag idiot belting the horn when leaving mates shld hv their car crushed, along with the morons shouting out the car windows! It is not funny, not warranted, not wanted and NOT LEGAL! Tell yr kids & grandkids today, please.
 
Ok to use horn “…to warn other drivers…”
Is an offence to use horn…”out of frustration of others’ driving…”.

I’ve had occasions where both have occurred at the same time. Eg, I’ve used my horn when someone’s cut me off because I was in their “blind spot”. They need to be warned and I was frustrated.

You are kidding! Crushing a car for using a horn? What next? Get your house demolished by a Caterpillar D9 bulldozer for hooning?

NEWS FLASH! We live in Australia, not North Korea!
 
It’s not news and not little known. it’s just ignored and I’m sure police have more important things to follow up. But it’s definitely not law in USA. The horn honking LA is unbelievable !

OK, SCENARIO: You're at the lights and they turn green and number three in the queue, the car at front doesn't move (face in phone maybe), car number two doesn't do anything, 5+ seconds have gone by (depending on intersection some lights stay green for a SHORT period) car number three gets on the horn to wake them up (long blast 2-3 seconds) IS that a fineable offense?? or are you prepared to wait until the lights go orange and miss your turn/chance?

New York City is even worse with all the yellow taxis. All those yellow taxis you may see in movies is what the streets are like in reality.

Try most Asian countries. Ten thousand horns going off at any one time at a single intersection!
 
Revenue raising at best. Won't be long and we'll getting charged for having bugs on the windscreen, driving a dirty car or not enough pressure in the tires. Anything to make up for the so called tax cuts.

That’s funny 😄 you should say that Dave, I’m in a four wheel drive club and we just got back onto the bitumen where we got pulled over by the WA cops for having dirty cars, I think it was the registration plates they couldn’t see, we wiped them clean and made them happy 😃 so they let us go……Rick

That is simply echo-location.Having ridden the famous Hooinda Dream 100 around Hanoi a few times it is tighter than a slow moving Tour de France Peloton in a narrow road. The assorted beep-beeps tell you where everyone is and without turning a hair another rider will overtake you and then cut in front leaving a gap of an inch or two between their rear wheel and your front wheel.They never look over their shoulders, they don't signal and the wing-mirror is mere decoration, but that horn enbles them to ride safely in a tightly packed mass.

Bats are equally skilful.
