Dhillon, a former director of a landlord and letting agency, was driving home after picking up his two children from kickboxing when the crash took place.
Dhillon, who was treated in hospital after the incident, later claimed he had been under stress due to his wife's depression and his father's terminal illness.
Dhillon had smoked cannabis, taken sleeping tablets before driving and claimed he had blacked out at the wheel of his Audi A4.
The husband of the victim said his "happy loving family had gone to nothing but a shell" since the crash.
"In fact, it sends out a message that people can go out and kill someone and then get away with it by saying they can't remember doing it," he added.
