Surprised fellow drrivers are passing such swift and harsh judgement..Walmart runs a tight ship, tighter than anyone else.. If you have a cellphone in the truck, it must be approved by the company to have it, and you cant use it while driving. For you drivers who have never driven at nights, it is terrible, and at that time of the morning your body just wants to go to sleep..It is terrible. I usually pull over, but sometimes you try to push it, and something like this may happen. It is a terrible thing to happen to a fellow driver.
