Final answer:
The CVIP is required for commercial vehicles only (option B), to ensure they meet minimum safety standards. Personal vehicles do not usually require a CVIP unless they are classified as commercial based on certain conditions.
Step-by-step explanation:
The vehicles that must undergo a Commercial Vehicle Inspection Program (CVIP) include option B) Commercial vehicles only. Personal vehicles are not typically required to get a CVIP unless they fall under specific conditions that classify them as commercial based on their use, capacity, or weight. The CVIP is a mandatory inspection to ensure that commercial vehicles meet a minimum safety standard on a regular or annual basis, depending on the jurisdiction. It's a preventive measure to mitigate the risks associated with operating commercial vehicles, which often carry heavy loads and travel long distances, increasing wear and tear.
