Which fluids must be checked for proper levels during the vehicle inspection?

The correct response highlights the importance of ensuring that key fluids in a vehicle are at proper levels for safe operation and compliance with safety standards. Engine oil is crucial for lubricating the engine components, while brake fluid is essential for effective braking performance. Coolant prevents the engine from overheating, thereby maintaining proper operating temperature, and transmission fluid is vital for proper gear shifting and overall transmission function.

Checking these fluids is part of a comprehensive safety inspection because each one plays a critical role in the vehicle’s performance and reliability. For example, low brake fluid can lead to brake failure, while insufficient coolant can result in engine overheating, both of which pose safety hazards. Regular checks of these fluids not only promote vehicle safety but also help maintain the vehicle in good working condition, potentially preventing costly repairs down the line.

In summary, the choice underscores the necessity of monitoring levels of these vital fluids to ensure optimal vehicle performance and safety.
