Whenever you're driving a semitruck, it is important to think about how the truck differs from a passenger vehicle and what that can mean for you.
Trucker fatigue is a significant problem on the highways and city streets around the country. These individuals often work long hours to ensure that their cargo makes it from the starting point to the final destination. Some of these loads are time sensitive, so they can't be delayed. This often results in many miles traversed each shift.
The size and weight of semitrucks make these vehicles rather dangerous, but most truckers know how to operate the rigs safely. In order to do this, however, they must be fully cognizant of what's going on at all times. Any kind of impairment decreases the public's safety.
