What are the three categories of motor vehicles?

The three categories of motor vehicles are based on weight classifications, which help establish regulations regarding licensing, registration, and road usage. The correct classification of light, medium, and heavy vehicles relates closely to their weight and capacity, which in turn influences road safety, insurance rates, and environmental regulations.

Light vehicles typically include passenger cars and small SUVs, while medium vehicles might encompass larger SUVs or vans. Heavy vehicles are usually commercial vehicles such as trucks and buses that exceed a certain weight threshold. Understanding these categories is crucial for both motorists and regulatory authorities, as it facilitates proper vehicle handling, compliance with road safety standards, and effective transportation planning.

The other options do not accurately represent the standard classifications used in transportation regulations. Categories like motorcycle, car, and truck focus on specific types of vehicles rather than their weight profile, which is essential for safety and regulation purposes. Similarly, compact, subcompact, and full-size are terms used primarily in marketing and consumer contexts rather than for formal classification within the transportation framework.
