A Highways Agency officer was killed this week when he was hit by a car as he dealt with a crash on the M25 in Kent.
The 59-year-old from the Gravesend area was struck by a Vauxhall Vectra at junction 5 of the motorway on Tuesday.
He had been attending a crash involving a car near South Chevening which left one person with a minor injury.
Two people in the Vectra were taken to hospital, one with serious injuries.
Sections of the M25 and M26 motorways were closed temporarily following the incident.
A Highways Agency spokesman said: “We can confirm a Highways Agency Traffic Officer was involved in a fatal incident at around 2.50pm yesterday at junction 5 of the M25 near Sevenoaks.
“The officer’s next of kin have been informed and our deepest sympathies are with them at this time.”
