One person was rushed to hospital Saturday morning following a collision on Whitemud Drive.

Police said a Lexus RX350 travelling west on Whitemud Drive lost control just before the Quesnell Bridge, colliding with the centre barrier between the west and eastbound lanes.

She reportedly got out of the vehicle and was speaking with another motorist who had stopped to assist when a black Dodge Nitro, westbound, slid into her and into the far right lane of the freeway.

The 31-year-old woman was taken to hospital with serious injuries.

The driver of the Nitro, a 48-year-old man, also suffered minor injuries and was taken to hospital.

Officers believe speed and vehicle maintenance may have been factors in the event. Impairment is not considered a factor.

Police later warned the public it is best to remain in your vehicle after a crash to wait for help to arrive.

“Most people have cell phones, call for help,” said Sgt. J.C. McLeod of the major collisions investigations unit. “In a case like this here, you’re on a main roadway, speeds are not 50 kilometres an hour—they are much higher than that—and so you're taking risks by exiting your vehicle to check on things.”

Traffic was delayed for several hours while police investigated.

The investigation is ongoing. Charges are pending.
