Police say a motorcycle driver ran a red light before a crash with an SUV that had traffic backed up in Regina's east end on Saturday.
They also say clogged traffic after the crash may have led to another nearby collision.
Just after 11:30 a.m. CST, the motorcycle and SUV collided at an entrance to Costco. Investigators believe the SUV was leaving the parking lot at University Park Drive, when the motorcycle drove through the intersection and hit its driver's side.
The 28-year-old motorcycle driver was taken to hospital with non life-threatening injuries, and later charged under the traffic safety act for operation of an unregistered vehicle, failure to wear a helmet and failure to stop at a red light. Nobody in the SUV was hurt.
Then, about half an hour later, another pair of vehicles crashed about one block north of the first scene at a service road near Victoria Avenue.
Police say a third crash in the area was not related to traffic snarls caused by the first two crashes. That one happened shortly afterward at the intersection of Truesdale Drive and University Park Drive.
There were no other major injuries.
Officers directed traffic at the scene throughout the afternoon.
