How are straight trucks classified?

Straight trucks are classified based on their gross vehicle weight rating (GVWR) and axle configuration. Typically, they fall into classifications that correspond to the number of axles and their weight capacities.

The correct classification for straight trucks includes options that reflect their common size and weight categories in the 3, 4, or 5 range. This classification acknowledges that straight trucks are designed for various utility and transport purposes, often including light-duty to medium-duty applications.

Choosing 3, 4, or 5 encompasses a broad spectrum of vehicles considered as straight trucks, signifying that this range effectively captures the most prevalent classes of straight trucks that one would encounter in vehicle rescue operations or transportation tasks. Higher classifications, such as those found in the other options, pertain to larger commercial vehicles not typically categorized solely as straight trucks. This makes the classification of 3, 4, or 5 most relevant and accurate for the purpose of identifying straight trucks in this context.
