Two lorry drivers are to stand trial over a crash on the M1 in Buckinghamshire that left eight people dead.
Six men and two women died in the crash involving two lorries and a minibus which happened over the August Bank Holiday on the southbound carriageway near Newport Pagnell.
Four other passengers were also hurt.
31-year-old Polish national Ryszard Masierak, and David Wagstaff, 53, both pleaded not guilty to eight counts of death by dangerous driving and four counts of causing serious injury at Aylesbury Crown Court on Friday.
Wagstaff did however plead guilty to eight lesser charges of causing death by careless driving, and four counts of careless driving, but he will still have to go on trial for the more serious charges that he denied.
The two men will stand trial on February 26 next year.
