You might consider yourself an expert behind the wheel, but that doesn’t mean you know every rule in the book. How about the weirdest ones? Best bone up on these rare rules before you're slapped with a fine!

The Aussie road rules you've never heard of

A NSW driver found himself in hot water after he was pulled over and police spotted a dog curled up on his lap.

The 31-year-old driver was chosen for a routine random breath test while driving on the Tuggerah Lakes Highway at Bateau Bay on Thursday.

But as he drove into the testing site a police officer noticed the unrestrained pooch.

“It was observed by police that he had a small tan coloured dog on his lap,” a post on the Traffic Highway Patrol Command Facebook page read.

“Driving with an animal on your lap is extremely dangerous and can interfere with the driver’s ability to control the vehicle.”

The man was issued a penalty noticed for driving a motor vehicle with a person or animal in lap and slapped with a $448 fine and three demerit points.

However, it seemed the driver wasn’t alone in not knowing having your pet sitting on your lap was an offence.

There were multiple people who commented on the post claiming they had no idea it was illegal.

“Does this even mean if they have a harness on and a short lead that is still a no?” one person asked.

“I never knew that was illegal, glad I read this,” another said.

One of the commenters didn’t seem very happy that this was a fineable offence.

“Glad they’re capturing the real criminals, it’s a bigger fine than if you were caught speeding,” they wrote.

Other people praised the police, pointing out an animal could easily get hurt or die if they aren’t restrained.
