To drive safely in the presence of large trucks and avoid collisions, you must be familiar with their physical capabilities and maneuvers.
Don't follow too closely or tailgate trucks. When you follow behind a truck and you cannot see the truck drivers side view mirrors, the trucker has no way of knowing you are there. Tailgating a truck, or any vehicle, is dangerous because you take away your own cushion of safety. Where will you go when the vehicle in front of you stops suddenly?
It is easy and extremely dangerous to underestimate the size and speed of an approaching tractor-trailer. A large tractor-trailer often appears to be traveling at a slower speed because of its large size. Many passenger vehicles/large truck collisions take place at intersections because the vehicle driver did not realize how close the truck was or how quickly it was traveling.
