A man who was convicted of dangerous driving, causing the death of an 83-year-old Surrey man, has been sentenced to one year in jail.

Gurjit Dhillon's car crashed into Pritam Benning while he waited at a Surrey bus stop in September 2009.

Benning died five days later in hospital.

Benning's son, Manjit Benning, said the family was disappointed with the sentence.

"You kill a man and you get one year in jail," he said outside a Surrey courthouse on Wednesday. "It's not right."

The Crown had originally alleged that Dhillon, now 28, was street racing in his black Corvette when he hit a car, lost control and struck Benning at the bus stop.

Witnesses said Dhillon might have been racing another car, a yellow Corvette. Despite appeals from Benning's family, the driver of the other car never came forward.

The Crown eventually dropped the charges of street racing.

Judge James Jardine said Dhillon, who was convicted last November, showed guilt and remorse and said he was suffering from post-traumatic stress disorder.

Jardine urged Dhillon to honour Benning's memory.

Marvin Stern, Dhillon's lawyer, said his client got a tattoo so he would never forget the crash.

"The tattoo is a very real indication of how he felt," Stern said.

"The tattoo was of Mr. Benning's name and the date of the incident with an inscription, 'The day everything changed.'"
