What type of fluid leaks may disqualify a vehicle from passing inspection?

A vehicle must be free from leaks of substances that could impact its safety and performance to pass inspection. Oil, coolant, or brake fluid leaks are significant because they can affect engine performance, hydraulic systems, and overall vehicle safety. For instance, oil leaks could lead to engine damage, coolant leaks may cause overheating, and brake fluid leaks can result in brake failure. Each of these fluids plays a crucial role in vehicle operation, and their presence on the ground signifies potential safety issues that must be addressed for the vehicle to be deemed roadworthy.

In contrast, while water leaks can occur from condensation or rain, they typically do not impact the vehicle's functionality or safety. Windshield washer fluid leaks are also not a critical concern for passing inspection since they do not affect the operation of the vehicle but rather the convenience of visibility. Fuel leaks, while pressing due to the risk of fire and explosion, are separately addressed in the context of their immediate danger and may also lead to disqualification, but they are often considered under a more specific category.

Thus, the emphasis on oil, coolant, or brake fluid leaks reflects the significant implications these fluids have on vehicle safety and performance, making this the correct answer for passing inspection.
