When a combination vehicle makes a low-speed turn - for example a 90-degree turn at an intersection - the wheels of the rearmost trailer axle follow a path several feet inside the path of the tractor steering axle. This is called low-speed offtracking. Excessive low-speed offtracking may make it necessary for the driver to swing wide into adjacent lanes to execute the turn (that is, to avoid climbing the inside curbs or striking fixed objects like telephone poles).
This performance attribute is affected primarily by the distance from the trailer kingpin to the center of the trailer rear axle, otherwise known as the wheelbase of the semitrailer. To prevent trucks from being too long to maneuvering safely around turns encountered in cities and towns, the maximum length allowed from the kingpin to the trailer tandems is set by the individual states.

Use Your Horn When Needed. Your horn can let others know you are there. It can help to avoid a crash. Use your horn when needed; however, it can startle others and could be dangerous when used unnecessarily.
Be very careful about startling people with your horn. Everyone considers tractor-trailer air horns to be an imminent warning of impending doom! You will have a "city horn" to go along with your air horn. The city horn sounds just like a car horn. Use that if you can get the job done with it, otherwise use the air horn.

Begin Early and Space out Your Studying: It is important to give yourself ample time before the exam to get familiar with the material and get your mind ready for the big day. Consider taking a training course online or in-person, if it's required. Shop around for a course that works best for you.
