Which of the following vehicles must have mudflaps when operated on public roads?

The requirement for mudflaps on vehicles operated on public roads is primarily aimed at reducing the spray of water, mud, and debris that can be kicked up by the tires. This can significantly improve road safety by minimizing visibility issues for other drivers and reducing the risk of damage to vehicles following behind.

The answer is that all vehicles with four or more tires on the rear axle must have mudflaps. This requirement encompasses a wide range of vehicles, including larger passenger vehicles, vans, and trucks that do not have trailers attached. The design is intended to ensure that the vehicles are compliant with safety regulations put forth by transportation authorities. By mandating mudflaps for these vehicles, regulations aim to diminish the splash and debris that can be hazardous when driving in wet conditions.

In contrast, the other options do not encompass the broad scope of vehicles subject to this requirement. For example, trucks with trailers may have specific regulations, but they are not the only vehicles that are required to have mudflaps. Motorcycles and light-duty vehicles (typically those designed for passenger transport) are not included in this category, as they do not meet the four or more tires criterion or may be subject to different regulations. Thus, the correct answer captures the essential safety standard applied
