Brent Parent was enraged when a pickup truck tried to pass him on the road. Instead of letting it pass, he toyed with the vehicle, repeatedly slamming on his brakes and finally forced it off the road.
When three people disembarked the damaged vehicle, Parent turned his truck around and returned to run over one of the passengers, killing 21-year-old Silas O'Brien.
In a road-rage case that stunned Canada, Parent was convicted earlier this month of criminal negligence causing death, dangerous operation of a motor vehicle and failing to remain at the scene of an accident. The British Columbia resident was given a five-and-a-half-year sentence and a 12-year driving ban.
"It's more or less what we expected," Rodger O'Brien, the victim's father, told reporters after the sentence. "We feel that it's a sentence that will likely not be appealed, so it's all good."
Authorities had sought an eight-year prison sentence and 15-year ban. Parent, 43, had 64 prior driving infractions on his driving record.
Road-rage episodes are hard for automotive experts to quantify and study, but motorists believe they are on the rise. In a survey from the Automobile Association Driver Education Foundation, 62 percent of respondents said they felt the behavior of their fellow drivers had changed for the worst in recent years.
Only 2 percent said it had changed for the better.
A study from the AAA Foundation that analyzed more than 10,000 suspected road rage incidents over the past seven years found that at least 218 deaths and 12,610 injuries had been caused by road-rage incidents.
