On Saturday afternoon, a passenger was caught on camera hanging out of car window on the A1.

Footage has been caught of the shocking moment a car passenger hangs out of a car window at 60mph to clean his friend's BMW for "banter".

A heart-stopping video has emerged showing the incident, which took place on the A1 on Saturday 22 July.

The front seat passenger can be seen hanging out of the window as the car hurtles down the dual carriageway near Grantham, Lincolnshire.

He appears to pretend to clean his friend's white BMW as he overtook.

To make matters worse, the car is travelling in the fast lane in torrential rain at the time of the dangerous stunt.

Police dashcam footage captured the incident and blasted the passenger's "deplorable behaviour".

Writing on the force's Twitter page, they said: "This deplorable behaviour was witnessed by #RPU on the A1 dual carriageway in Grantham, travelling at 60mph. 

"Passenger was cleaning his friend's vehicle for 'banter'. Driver and passenger reported for multiple offences and section 59 warning issued."
