Thank you Bearisgrey. My Dad is a truck driver and now my Mom rides with him. I have spent my life praying for him to return home safe and sound but now I have to worry about both of them. My Dad has had many accidents because of ppl in cars that think they can turn infront of a truck or don't realize a truck is coming to a stop and they wind up under his rig.. Problem is they don't always feel when they have been rear ended and proceed to drive before someone gets their attention that something is wrong. I am not defending all truck drivers because I have seen some lousy ones.
