What is one ease criterion for a successful inspection?

A successful inspection primarily focuses on the vehicle's safety and operability, which makes the criterion of having no visible fluid leaks crucial. Fluid leaks can indicate underlying issues that may compromise the vehicle's performance or safety. For example, oil leaks can lead to engine damage, while brake fluid leaks can severely affect the braking system's efficacy. Therefore, ensuring that a vehicle has no visible fluid leaks is vital for it to pass inspection and maintain road safety.

The other options, while they may contribute to the overall condition of the vehicle, do not directly affect its safety or functionality in the same way. Minimal cosmetic damage does not impact how a vehicle operates, nor does having a specific color, which is purely aesthetic. All accessory lights functioning is important for visibility and safety, but it is one of many factors considered in a comprehensive inspection, rather than a standalone ease criterion.
