In terms of vehicle height regulation, which of the following is true for passenger vehicles?

The correct answer highlights the importance of vehicle height regulations for ensuring safety and standardization across passenger vehicles. In this context, passenger vehicles must adhere to specific height limitations to promote stability, maneuverability, and overall road safety. A maximum height limit of 22 inches is established to maintain these safety standards. This regulation is in place to prevent vehicles from being excessively tall, which can negatively impact handling and increase the risk of rollovers.

The other options suggest either a maximum height that is too low, which would not be practical for most modern passenger vehicles, or minimum height requirements that do not align with the established regulations. By adhering to a maximum height of 22 inches, the regulation ensures that vehicles remain safe for operation on public roads while accommodating necessary design elements.
