A police officer from Merseyside who died in a crash on the M58 in Lancashire spent several years supporting road accident victims.
Pc David Shreeve was on a motorcycle training course when his bike collided with a lorry in Skelmersdale.
The 38-year-old, who joined Merseyside Police in 1987, leaves a wife, a two-year-old son and a daughter, five.
Chief Constable of Merseyside, Bernard Hogan-Howe, paid tribute to Pc Shreeve, who was "popular and well-respected".
Pc Shreeve, who lived in Wirral, was posted to the traffic division in March 1994 where he trained as a family liaison officer three years ago.
He regularly supported victims of serious and fatal road traffic collisions.
Chief Constable Hogan-Howe said: "This has truly been a tragic loss of an experienced officer, who spent his recent years caring and offering support for others.
"Dave was popular and well respected by his colleagues, going out of his way to tutor and mentor officers of less experience than himself.
"The letters and phone calls of thanks he received from bereaved families and victims of crime are testimony also to his kindness and professionalism, qualities which will be sorely missed by us all."
