Drunk driving has no place on the roads in America. Even a single night driving while intoxicated could lead to a crash with serious repercussions. A person who made a mistake could end up facing serious charges, and victims could be at a loss while they struggle to recover or deal with the loss of loved ones.
Trucker fatigue is a serious problem among truck drivers. They work long hours, and many take breaks for only a short period to nap or get something to eat. While the law allows them to drive for 11 hours straight and to work for 14 hours each day (three of which have to be parked/not in the vehicle), this is still a long work day that could result in collisions due to fatigue.
You were hit by a car, and the driver, fortunately, stayed at the scene. You've struggled to make peace with the fact that the driver didn't intentionally hit you because you've been left with severe injuries.
