Which of the following mistakes should you avoid when driving around trucks?

1) Do not cut off a truck in traffic or on the highway to reach your exit or turn. Take a moment to slow down and exit behind a truck – it will only take a few extra seconds. 2) Do not linger alongside a truck when passing. Always pass a tractor-trailer completely and always on the left side. If you linger when passing any vehicle, your position makes it impossible for the trucker to take evasive action if an obstacle appears in the road ahead. 3) Tailgating a truck or car is dangerous because you take away your own cushion of safety if the vehicle in front of you stops short. When following behind a truck, if you can’t see the truck driver’s outside mirrors, there is no way the truck driver can see you. 4) Never underestimate the size and speed of an approaching tractor-trailer. Because of its large size, a tractor-trailer often appears to be traveling at a slower speed than it is.
