Alberta Written Class 4 Drivers License Practice Test

The correct answer describes a towed trailer, which is primarily designed to be pulled by another vehicle. Towed trailers typically have their axles located at or near the rear, allowing them to be hitched to a towing vehicle for transport. This positioning helps distribute weight effectively during travel and enables better handling and stability when being towed. In contrast, a truck tractor typically has multiple axles configured to handle heavy loads, often located in the front and rear for better weight distribution and control. A farm vehicle may have various axle configurations depending on its design and intended use but does not specifically fit the description of having axles only at the rear. A single-axle truck usually has a front and a rear axle, which does not align with the specific definition of having axles only at or near the rear end.
