Woman mocked over rant against slow-driving ticket

A woman's rant over police pulling her over for driving too slowly in the right lane of a busy highway has come back to bite her, after it was revealed that she had broken the law.

The unnamed New South Wales resident posted a video on Facebook explaining that she'd been pulled over for something that wasn't illegal - saying there was no signage suggesting that driving slowly in the right lane is a crime.

"There's absolutely no sign telling me I have to take over to drive in the right lane," she said, labelling the behaviour of police officer who pulled her over "disgusting".

"I will have you all exposed and reported, pulling me over for no reason," she wrote on the caption of the Facebook video, in which she says she was driving 85km/h in a 90km/h zone.

At the end of the footage, the woman says she was headed straight to the police station after the incident to report the officer who pulled her over.

The woman says the officer told her she had to be overtaking if she was to drive in the right lane - something she claimed isn't enshrined in law, and thus he was wrong about.

However it turns out it actually is illegal - with road rules in New South Wales stating that drivers must keep left unless they are overtaking or turning right on roads with a speed limit of more than 80km/h.

The woman was also taken to task by myriad Facebook users for not knowing she needed to keep left if she was planning on driving slowly.
