Four people in Saskatoon were sent to hospital after a pickup truck smashed head-on into another vehicle while travelling in an oncoming lane of one of the city's busiest roads.
Police said the truck was northbound on the wrong side of Circle Drive, a divided, four-lane road in the city's north end near the airport, just before midnight on Tuesday.
The truck smashed into a southbound vehicle, trapping both drivers inside.
A third vehicle heading south smashed into those two vehicles and careened into the ditch. The 24-year-old female driver of that car suffered only minor injuries.
The people in the other vehicles were not so lucky. Both drivers suffered multiple broken bones and had to be pulled out of their vehicles by firefighters using the Jaws of Life. A male passenger in the southbound vehicle, aged 21, also had multiple broken bones.
Police said the condition of the truck driver was life-threatening, while none of the other victims' injuries was considered life-threatening.
Officers were still waiting to speak with the driver of the pickup truck who, according to a police spokeswoman, may have accidentally turned onto the wrong side of Circle Drive at Laurier Drive, about 3.5 kilometres from the scene of the accident.
"It's possible he [the driver] may have become confused," Alyson Edwards with the Saskatoon Police Service told CBC News, adding that police were checking to see if the man was from outside the area and unfamiliar with the city.
Saskatoon police said alcohol was not a factor. Police were continuing their investigation, and no decision had been made on whether charges will be laid.
