The incident has been highlighted by Surrey Police road policing officers, who said the woman fell from the car into a “live lane” between junction six and the Clacket Lane Services at 1.30am on Saturday.
A force spokesman said the woman was treated at the scene by paramedics and no arrests were made.
In a post on Twitter, the Roads Policing Unit said the woman was not seriously injured, before adding the hashtag “#nowords”.
The officers posted: “The front seat passenger was hanging out the car whilst filming a SnapChat video along the #M25. She then fell out the car and into a live lane.

One Twitter user responded: “Should be made to pay for the closure of the road, made to pay the police and highways for dealing with the complete lunacy she has caused.”
While another wrote: “The worst thing about this is that had she been hit – the poor driver who hit her would have to live with that for the rest of their life. No one expects to be dodging human bodies on a motorway and an emergency stop may have caused a serious pile up and further loss of life.”
A Surrey Police spokesman said: “Officers were called to the M25 between junction six and Clacket Lane Services shortly after 1.30am this morning following reports of a female falling out of a moving vehicle.
“The woman was treated by paramedics at the scene and her injuries were not life-threatening or life changing. No arrests have been made.”
