Patrick Van Den Kieboom and his wife were pulled over on Saturday night while travelling in their right-hand-drive Renault Espace, imported from the UK.
Van Den Kieboom told foreign publication Gazet van Antwerpen that he was driving, and when pulled over, his wife wound down her passenger-side window.
Not realising the car was right-hand drive, the policewoman proceeded to ask the woman – who by this stage had developed a case of the giggles – if she’d had anything to drink, before conducting the breath test.
The driver said he had consumed a couple of beers earlier in the day, and admits it “would have been close” had he been tested.
Without testing the actual driver of the vehicle, the inattentive officer congratulated the passenger for returning a negative result, and wished her a safe trip.
