A woman was hit with multiple fines after police spotted her taking a child to school on an e-bike in Liverpool, in Sydney's south-west.
So what did police say she did wrong?
Posting on the Traffic and Highway Patrol Command Facebook page, police said the woman had been pulled over for not complying with a number of road rules - including riding an unregistered and uninsured motor vehicle, not having the correct licence, and carrying a passenger under eight years old on the bike without using a sidecar.
The child, police allege, was five years old and riding pillion.
"Police would like to remind the community that these E-Bikes are considered motor vehicles in the state of New South Wales and are required to comply with all ADR (Australian Design Rules)," police wrote.
"They need to be road registered, display official number plates issued by Service NSW and the rider must hold a Class R driver licence and wear the correct protective helmet as per AS/NZS 1698."
The woman's fines added up to $2575.
Transport and Main Roads Queensland has put drivers to the test with this trick road rule question.
"The red car and yellow car are approaching a T-intersection," it posed in a Twitter post.
"Who needs to give way?"
A man was travelling along Monash Road in Blacktown, in Western Sydney, about 7.10am on Friday last week.
Police, however, clocked the green Toyota allegedly driving at more than double the speed limit.
The Toyota was detected driving at a speed of 103kph instead of the 50kph allowed on that road.
When the driver was stopped, he pulled out a heavy vehicle licence.
His response?
"I am so late for work," the 22-year-old man said.
The man was issued with a penalty notice for exceeding the speed limit by more than 45kph.
His licence was suspended on the spot for six months.
And his vehicle's registration plates were confiscated and sent to the Road and Maritime Services for three months.
Australia is the land of some strange and wacky road rules - not all of them well-known - but just how strictly are they enforced?
Drivers across the country have periodically been caught out for unusual requirements while behind the wheel of a car that result in fines worth hundreds of dollars each, with some infringements even costing millions within years.
Test your knowledge of the rules.
The driver of the blue car is turning left at a stop sign.
The driver of the red car is doing a U-turn.
So who needs to give way?
If you guessed the red car, then you are correct.
"When you are doing a U-turn, you must give way to all other vehicles and pedestrians— even if other vehicles are facing a give way or stop sign," Queenland's transport department said.
"At intersections without traffic lights or at breaks in the centre island of the road, you must not do a U-turn if there is a no U-turn sign."
This driver was fined $387 with double demerit of 10 points over the Australia Day long weekend in New South Wales.
Police pulled over the driver after noticing the driver had a phone holder device in their hand.
Question: Are phone holders legal?
Answer: Phone holders are legal if they are commercially manufactured and fixed to your vehicle.
They must not obscure your vision and should not be used while dirving.
This driver didn't have their deivce mounted and instead was holding it while driving.
Once stopped, she told police, "Yeah because the cradle is broken what can I do? I need GPS."
Motorists almost always have the guidance of road signs, lines and traffic lights to help them navigate traffic.
But in the event two cars arrive at an unsigned, unsealed crossroad at the same time, which car must give way?
The answer is the red car must give way to the orange car.
You must give way to vehicles on your right at an uncontrolled crossroad.
A parking sign in one Sydney council has sparked confusion among residents.
Listener Jane told 2GB's Ben Fordham she was fined by Canada Bay Council after parking her car in a "vehicles with trailer" parking spot at Cabarita Park.
But Jane is disputing the fine with the local council due to the "confusing" wording.
Jane argues the sign was unclear as to whether cars without a trailer can park in the spot, outside of the stated times of Saturday, Sunday and public holidays.
She believes the sign should instead say "vehicles with trailer only".
Cabarita is a waterside suburb situated in Sydney's inner-west.
Jane says she has taken multiple photos of other cars parking in the same spot, some with trailers and others without.
Lawyer Daryl backed Jane, texting in to Fordham's show that he is willing to take on the case and represent her in court.
New South Wales drivers are being warned any driving offences over the Christmas Holidays will result in double demerit points well up until the 1st of January next year - that's if they can read the sign.
Twitter user Andrew Laird pointed out bemusedly this road sign, which warned motorists that double "dermits" currently apply.
This passenger has exited the red vehicle while it's stopped at a give-way sign.
Is that allowed?
A) No. You must not get off, or out of, a moving motor vehicle.
This includes causing a hazard to any person or vehicle by opening a door or getting off or out of a vehicle stopped in traffic, at traffic lights, or at a give-way sign.
