The unnamed couple, a 28-year-old man and a 22-year-old woman, were caught in the act late on Easter Sunday by traffic police on the E18 highway, some 40 kilometres (25 miles) west of Oslo.

Officers who clocked the couple’s silver Mazda 323 racing at 133 kilometres per hour in a 100 zone realised they were doing more than just breaking the speed limit, police told AFP.

“It was veering from one side to the other because the woman was sitting on the man’s lap while he was driving and doing the act, shall we say,” said Tor Stein Hagen, a superintendent with Soendre Buskerund district police.

“He couldn’t see much because her back was in the way,” he added.

“Why they did it on a highway with such a high risk we don’t know.”

After following the couple for nearly a kilometre, officers pulled the car over at a service station.  He now faces fines worth several thousand Norweigan crowns and a lengthy driving ban for reckless driving. When the case goes to court it should be an open and shut proceeding, as the police recorded the carnal activities with their dash cam for use as “evidence” later on.
