A police officer had a surprise when he pulled over a car for speeding to find what appeared to be an alien in the front seat.

The Atlanta Journal-Constitution reported the motorcycle officer was greeted by the life-sized doll, seat-belt and all, after he had clocked the driver going at 84mph (135kph) in the US state of Georgia.

Umm, the things you see during everyday patrol. #ET #doesthisqualifyforHOV #IndependenceDay

“He did not mention as to why he had an out of this world passenger,” said George Gordon, a spokesman for police in Alpharetta where the bizarre incident took place.

Of course, extra-terrestrial sightings such as this invariably cause a stir – so the little guy with the big head has had some reaction online.

While many wondered what happened to the driver after he was pulled over.

Perhaps their passenger is a good luck charm for the driver after all, as police said he received just a verbal warning for his offence.
