A 47-year-old man from Luton has died after a collision between two lorries on the A5.
It follows an incident involving two HGV vehicles, travelling in opposite directions, in the early hours of Friday morning.
The smash, at Kilsby Road, Watford, at approximately 1am resulted in a fire.
The driver of one of the lorries, a 47-year-old from Luton, died at the scene.
The driver and passenger of the other lorry were not seriously injured but taken to Northampton General Hospital as a precaution.
Both survivors, who are male, were subsequently arrested on suspicion of causing death by dangerous driving.
Both remain in police custody for questioning.
Due to ongoing investigations, road damage and vehicle recovery, the A5 on both directions is likely to remain closed throughout the day.
Road closures are currently in force between the A428 at Crick (Junction 18 M1) and A45 at Weedon (Junction 16 M1).
