Which of the following is NOT a type of commercial vehicle?

A passenger sedan is considered a personal vehicle rather than a commercial vehicle. Commercial vehicles are designed primarily for the transportation of goods, materials, or passengers for business purposes. In contrast, a passenger sedan is intended for personal use, providing comfort and convenience for individuals rather than serving commercial functions. This distinction is essential when categorizing vehicles for regulations, licensing, and operational use.

On the other hand, options like the pickup truck, box truck, and flatbed truck are designed for commercial purposes, serving roles in delivery, transport of goods, and other business-related functions. Recognizing these differences is crucial for understanding the classifications of vehicles within the commercial driving framework, particularly when seeking a Commercial Driver's License (CDL).
