A new report has revealed Australia’s most bizarre road rules

Carrying a bag of spuds in their car could land motorists in hot water. Here we reveal some of Australia’s most unknown, or bizarre road rules.

New research has revealed the most bizarre road rules in Australia including restrictions on how many potatoes motorists could transport in their vehicles.

Sticking a hand out of a car to wave to someone was also considered breaking the law.

According to the driving regulations in all states and territories, it is illegal for any part of a drivers body to be outside of a moving car, meaning the act could land them in hot water with the authorities.

It’s one of just several little known rules that apply to Australian drivers.

Research by Budget Direct also revealed honking a car horn as a way of saying goodbye was also considered illegal across Australia.

Driving is a rite of passage in Australia but it’s difficult to keep up with the more bizarre road rules.

Road regulations state the only reason drivers should use their horn is to: warn other drivers your vehicle is approaching, trying to get animals off the road, or as part of an antitheft or alcohol interlock device.

Those busted leaving their car doors unlocked could also been in line for a big fine.

In NSW, Queensland, Victoria, South Australia and the ACT, drivers could be fined for not properly securing their vehicle.

Additionally, in some states motorists could be slapped with a $117 ticket if their window is left open by more than 2cm.

Driving too slowly is also illegal across all states and territories in Australia – too slowly can be defined as “unreasonably obstructing drivers or pedestrians”

Up until May this year, if drivers had a big bag of spuds in their boot they could have also been breaking the law.

Waving goodbye to a friend could also be considered illegal

The Potato Marketing Authority were able to stop and search a persons vehicle if they suspected a driver might have more than 50kg of potatoes on them.

Potato Inspectors have the right to demand the name and address of anyone in possession of what appears to be more than 50 kgs of potatoes.

The law, which existed from 1946 up until May this year, included a $2000 for a first offence, or $5000 for repeat offenders.
