What do fenders need to cover to pass inspection in Honolulu County?

Fenders are designed primarily to cover the tires of a vehicle, ensuring that they do not protrude beyond the body of the vehicle. In Honolulu County, for a vehicle to pass inspection, the fenders must effectively cover the width of the tire tread. This requirement is crucial as it helps prevent debris from the tire from being thrown onto the road or other vehicles, thereby enhancing safety. If the fenders do not adequately cover the tire tread, it can result in safety hazards, including reduced visibility for other drivers and increased risk of accidents.

Other options do not meet the specific requirement for fender coverage. The entire surface area of the vehicle is not relevant because it does not pertain specifically to the function of fenders. Height of the vehicle tires is not a consideration for fender coverage. While bumpers are important for overall vehicle safety, they do not determine the compliance of fender coverage regarding tire visibility. Thus, the focus on the width of the tire tread is vital for passing inspection.
