Authorities in Tasmania didn't see anything wrong with emblazoning an anti-drink-drive message across the side of their breath-testing vans.

That is, until someone bothered to open the door.

That's when "real mates don't let mates drink drive" suddenly became "real mates drink drive."

The police department instructed officers to remove the Mad magazine fold-in outtake from all vans by the end of week.

A department spokesman told Australia's ABC News it was up to the Road Safety Advisory Council to cover any expenses incurred since it was they were responsible for the flawed campaign.
