In yet another incident of a pedestrian being struck by a vehicle turning left and approaching from behind, a woman has sustained life-threatening injuries this week. It happened Thursday about 5:15 p.m. as a woman, 47, crossed Markham Rd. on the south side of Steeles Ave. walking east to west. A car driven by a man, 41, approached from the rear on Steeles to make a left turn onto Markham. He hit the woman and now police are asking for help locating security or dash camera footage of the scene. This blind-side jeopardy for pedestrians seems to throw up dozens of such accidents.
