Mark Richardson apologises for driving 'slow in the fast lane'

Mark Richardson has apologised for outraging motorists after admitting he "drives slow in the fast lane".

On Thursday The AM Show sportsreader said while on the way home from Hamilton recently, he dawdled in the Waikato Expressway's right-hand lane at a "respectable 95km/h".

His passenger told him that on a dual carriageway he had to be in the left-hand lane if he wasn't overtaking.

Mark said that was "rubbish", and that he had "every right to be here in the outside lane... It's not the law, it's an advisory in the road code".

He acknowledged sticking left is the 'courteous' thing to do but he "chooses not to be courteous".

But by Friday morning, following dozens of responses from grumpy viewers, Richardson accepted he was wrong.

"Ignorance is no defence in the law and I did think you were entitled to sit out there in that right-hand lane.

"Apparently you're not. Because it's in the road code, yes, it is technically against the law if I could be in the other lane so I apologise."
