Sorry to hear about your accident. My thoughts and prayers for a speedy recovery are with you. Someone turning in front of me without warning and being rear ended are 2 of my biggest concerns.
Two weeks ago, my neighbor was stopped at a light less than a mile from our home. He admits he wasn't watching his mirrors while he was stopped. He said he was suddenly bumped forward about 2 feet. When he turned around to see what had happened, all he saw was the grill of a Cement Truck with it's bumper engaged with the trunk on his bike. He said when he saw the close call he had, his anger transitioned to relief that it wasn't worse.
I only mention this because it certainly sounds like you had an extremely close call and it's fortunate that even though you are bruised and contused it could have been a lot worse for you and your family.
Life is a Blessing, God Bless!
