What is the result if a vehicle's accessory drive belt has foreign contaminants but all accessories function normally?

If a vehicle's accessory drive belt has foreign contaminants, it is a cause for concern during a state inspection, even if all accessories are functioning normally. The presence of contaminants can lead to premature wear and tear, potential slippage, or complete failure of the belt over time, which can affect the overall operation of the vehicle and its safety. Therefore, the vehicle should not pass inspection with a contaminated accessory drive belt, as it does not meet the necessary standards for proper maintenance and safety. Regular maintenance and cleanliness of all vehicle components are essential for ensuring long-term reliability and preventing breakdowns.
