Two boys, 11 and 12 years old, on an electric dirt bike were seriously injured when they cut a car off and were struck Thursday afternoon in southwest Edmonton, police said. The boys were in the far left turning lane on Windermere Boulevard, and instead of turning left onto Terwillegar Drive when the advance signal turned green, they went straight and were hit by a Ford Fusion making the turn from the wider turning lane. EMS responded at 2:30 p.m. and took the boys to hospital with serious but non-life threatening injuries. The driver of the car stayed on scene and was not injured. The 11-year-old boy was driving the dirt bike, police said. The crash is under investigation and speed or alcohol are not being considered as factors. The use of electric dirt bikes on public roadways is illegal in Alberta. CTV News Edmonton asked Edmonton police if the boys were wearing helmets.
