What type of vehicles accounted for 6.9% of vehicle fires?

The correct choice refers to non-passenger vehicles, which includes a broader category of vehicles that are not specifically designed for transporting people. This encompasses vehicles such as buses, vans, motorcycles, and various types of trucks that may be used for commercial purposes but do not carry passengers as their primary function.

Understanding that 6.9% of vehicle fires are attributed to non-passenger vehicles highlights the risks associated with this category, which can be influenced by factors such as the nature of the cargo, maintenance practices, and the environments in which these vehicles operate.

In contrast, passenger vehicles primarily consist of cars used for personal transportation, while freight transport vehicles and large commercial vehicles are more specialized categories that might not fully encapsulate the diversity of non-passenger vehicles. The percentage indicates a significant portion of vehicle fires that require awareness, especially among those involved in commercial operations or fleet management.
