An engineering and construction company has been fined £250,000 for safety failings after a surveyor was killed by a reversing lorry during work to widen the M25 near Dartford.
Richard Caddock was talking on a mobile phone and could not hear the approaching truck above the noise of nearby motorway traffic, when he was hit from behind in 2008.
The Health and Safety Executive prosecuted his employer Costain Limited for failing to ensure adequate precautions were in place to separate the movements of people and vehicles.
Maidstone Crown Court heard that Mr Caddock had left a parked van and was walking northbound along a section of the central reservation closed off as part of a £65 million scheme to ease congestion between junctions 1b to 3.
As he talked on the phone, a tipper lorry delivering crushed stone entered the same section and reversed northbound. Mr Craddock had walked approximately 30m when the truck hit him.
The surveyor sustained multiple injuries as a result of being run over by the eight wheel vehicle and was pronounced dead at the scene.
After the hearing HSE Inspector Melvyn Stancliffe said:
"This was a terrible tragedy that could easily have been avoided had Costain Limited implemented basic safety precautions.
"The movement of people and vehicles on construction sites requires careful planning and effective control. It must be considered a critical part of transport management. This case highlights that a failure to be in control can have devastating consequences."
