At approximately 3:00 pm Saturday Oct 28th I was crossing with the light in my wheelchair @ Lauzon Rd & St Rose & was hit. The car is very bright white with darker tinted windows all around. I'm glad he was just rolling & not accelerating. He didn't attempt to get out of his car,by time my wheelchair scraped the front end of his car to get off the road to the sidewalk he was gone & I've no idea what direction he drove off to. I was crossing to NW corner travelling towards the river & he was facing East. .if anyone saw anything please reply. My left arm got crushed between my chair & his car & is sore other than that I'm ok. Thank you Creator for watching over me.
