What condition must door handles and latches meet during inspection?

During the inspection, door handles and latches must meet several important conditions to ensure safety and functionality. Proper operation is crucial; this means that the door handles should open and close smoothly without sticking or jamming, allowing for easy access to the vehicle's interior. Secondary or safety catches are also important because they provide an additional level of security, preventing the door from inadvertently opening while the vehicle is in motion. Proper adjustment is necessary to ensure that the components align correctly, which contributes to the overall effectiveness of the door mechanism and prevents any potential malfunctions.

Since each of these conditions—proper operation, the presence of secondary or safety catches, and proper adjustment—contributes to the safety and functionality of the vehicle doors, all of these aspects must be met during the inspection process. Therefore, the most comprehensive answer encompasses all of these criteria, making it clear that they all play a vital role in ensuring that door handles and latches are in proper working condition.
