Definitions:

Thrustline

Vehicle directional tracking line. Properly set axles should track perpendicular to the vehicle centerline. In other words, the rear wheels should track directly behind the front wheels when the vehicle is moving straight ahead, resulting in a directionally true thrust line. If this were not the case, some dog-tracking tendency would result.

Hard Steering

A condition where the steering of a vehicle becomes difficult, often due to low power steering fluid, malfunctions in the steering system, or tire issues.

Highway Tractor

A type of truck designed primarily for the transportation of goods over long distances on highways.

Loaded Trailer

A trailer that is carrying cargo or load, as opposed to being empty or unloaded.
