Where must the results of the safety and mechanical defect inspection be shown?

Answer: B — The inspection certificate

The results of the safety and mechanical defect inspection must be shown on the inspection certificate. This certificate serves as an official document that verifies whether a vehicle has passed or failed the inspection, detailing any safety or mechanical issues that may need to be addressed before the vehicle can be legally driven. The inspection certificate is critical in ensuring transparency and safety for both the seller and the potential buyer, providing an accurate record of the vehicle's condition at the time of sale. Other documents, such as the bill of sale, repair log, or Wisconsin Buyers Guide, may provide related information, but they do not specifically contain the detailed results of the inspection in the same way that the inspection certificate does. For instance, while the Wisconsin Buyers Guide may summarize certain aspects of the vehicle and its sale, it does not serve as the official record of the inspection results.
