The jury in the trial of a fireman accused of causing death by dangerous driving while on an emergency call has retired to consider its verdict.
Leteef Kadri Sheikh, 52, of Marlow Avenue, Luton, died a month after his car was in collision with the fire engine, Luton Crown Court was told.
Robert Hulatt, 28, of Bromham near Bedford, denies causing death by dangerous driving on 11 September.
Mr Sheikh was on the school run with his wife and daughters the court heard.
Mr Hulatt was at the end of a 15-hour shift and on his way to a house fire, where it was thought a man was trapped, when he collided with a car in Chapel Street, Luton.
All those in the car were injured and Mr Sheikh died in October.
The prosecution said he should have slowed down because he had no view of one side of the junction.
The prosecution alleges Mr Hulatt, of Browning Close, should have approached the junction with Windsor Street more slowly, as there is a blind spot which he would have been aware of.
Mr Hulatt said the route was familiar and the fire engine had its sirens blaring and lights flashing.
"I am absolutely devastated," he told the court.
"I cannot imagine what the family are going through.
"I think about it first thing in the morning, all through the day and the last thing at night. I don't think I will ever lose that for the rest of my life."
