What term is commonly used to refer to vehicles that provide public transportation services?

The term "Public Utility Vehicles" specifically refers to vehicles that are authorized to provide transportation services to the general public. This designation includes various types of vehicles, such as buses, taxis, jeepneys, and tricycles, which are designed to transport passengers for a fare. These vehicles typically operate on set routes and schedules to meet public transportation needs.

On the other hand, private vehicles are owned by individuals for personal use and do not provide public transportation services. Commercial vehicles encompass a broader category that includes vehicles used for business purposes, such as delivery trucks or service vehicles, but this term does not specifically indicate that they serve the public in a transportation capacity. Lastly, while "motor vehicles" is a general term that includes all types of vehicles powered by motors, it lacks the specificity to denote those that are utilized for public transport.

Therefore, "Public Utility Vehicles" is the most accurate term to refer to vehicles designated for public transportation services, highlighting their role in facilitating passenger movement within the community.
