Definitions:

Multi-axle Vehicle

Multi-axle vehicle is a term for vehicles equipped with more than the standard two axles, providing additional support for heavy loads or improving maneuverability.

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.
