After reading most of the comments and opinions, the majority of people are misinformed or haven't checked the facts on trucking. Truck drivers are randomly tested for drugs at any time. Truck drivers in general are safe. Most wrecks involving autos and trucks are caused by the auto driver. Drivers are already subject to be stopped and checked at any time. The fatigue problem today is the HOS rules in place now, forcing a driver to drive sleepy, ( not tired ). Auto drivers should be subjected to the same checks that trucks are if safety is your concern.
