OSLO, May 4 (Xinhua) -- A driver of electric car in Norway's capital Oslo had to pay 5,350 kroner (617 U.S. dollars) for using a doll as fellow passenger, newspaper Aftenposten reported Thursday.

Oslo police stopped "a suspicious couple" in an electric car on a collective transport lane during morning hours. Neither winter jacket, sunglasses, nor black wig were not enough to trick them, Aftenposten said.

The Oslo route on E18 road is regulated for electric cars, but between 7 and 9 in the morning, it is only allowed in case there is at least one extra passenger in the car.

"A few days ago, the traffic corps had control of the public transport on E18 entering Strand, a stretch regulated for electric cars -- between 7 and 9 o'clock you can only use the field if you have a minimum one passenger," Oslo police wrote on their Facebook page.

"Then this couple passed by. The driver was allowed to drive 5,350 kroner poorer -- the fine was paid on the spot," the police wrote.
