Two Barnsley men have been found guilty of encouraging dangerous driving after a crash left four dead.
Nathan Jackson, aged 21, of Higham Common and Stephen Hebden, 23, of Dodworth Road, were found guilty following a trial over a crash in which four friends died when the quad bike they were on was hit by a car travelling at 140mph as vehicles raced along a bypass.
The racing scenes that led to the deaths of Ryan Beal, 20, Brandon Brown, 20, Alexandra Binns, 18 and Terrie Kirby, 16, were likened to the film The Fast And The Furious during the trial at Leeds Crown Court.
A jury was told how the friends were out celebrating Miss Kirby's birthday when the quad bike they were riding on was struck by a Nissan 350Z travelling in the same direction.
The driver of the Nissan, Daniel Raynor, and his front-seat passenger, Matthew Todd, admitted charges of causing death by dangerous driving and another five men were on trial accused of encouraging the dangerous driving.
Yesterday three of the men - George Tomlinson, 25, of Hall Croft, Netherton, Wakefield; Lee Fisher, 29, of Pond Street, Barnsley and Bradley Lockwood, 22, of Rotherham Road, Barnsley - were cleared.
But Jackson and Hebden were found guilty and are to be sentenced with Raynor and Todd at a later date.
During the trial it emerged that the car which crashed into the quad bike on September 27, 2015 was taking part in a high-speed racing involving a number of people and several vehicles on the A6201 Hemsworth bypass in West Yorkshire.
Two groups had travelled from Wakefield and Barnsley to use the stretch of road for racing as spectators watched from the sides of the road and a railway bridge.
Analysis of a satnav in the Nissan which crashed showed it was doing 140mph at the time of the impact with the quad bike and had reached 144mph on previous runs along the single carriageway road
