Bedfordshire Police have released CCTV footage of the M1 between junction 12 and 13 from February 14 last year.
It shows the moment two Newport Pagnell friends lost their lives.
Tom Aldridge, 20, and Nathan Reeves, 23, tragically died when a coach collided with their car, which was stationary on the hard shoulder.
Allan Evans, 59, from Islington, London was driving the men home following a night out in London.
A fourth man, Jake Dorling, suffered serious injuries in the collision including a fractured skull and a punctured lung.
The jury heard how Peters failed to see signs saying that the hard shoulder was not to be used except for in emergencies and travelled along it for almost three minutes before colliding with the car – which had its hazard warning lights activated.
The four had pulled over on the hard shoulder of the motorway after the oil light lit up on the dashboard. The driver had just finished topping up the oil and was preparing to set off again when the collision occurred.
Charles White, senior crown Prosecutor for Thames and Chiltern crown prosecution service, said: “This case involved a terrible incident, which led to the untimely deaths of three men and the serious injury of another on the M1 near Flitwick, Bedfordshire last February.
“This is a tragic waste of these lives and could have been avoided.”
