Maryland State Auto Safety Inspector Practice Exam

During a safety inspection, it is essential to check various fluids that ensure the safe and efficient operation of the vehicle. The correct choice includes engine oil, brake fluid, transmission fluid, coolant, and windshield washer fluid, as each of these plays a vital role in vehicle performance and safety.

Engine oil is crucial for lubricating engine components, preventing wear, and maintaining optimal engine temperature. Brake fluid is vital for the braking system's function, as it enables the transfer of force from the brake pedal to the brake components. Transmission fluid ensures smooth gear shifts and lubricates the transmission's moving parts. Coolant helps regulate engine temperature and prevents overheating, while windshield washer fluid is necessary for maintaining visibility by keeping the windshield clean.

Each of these fluids contributes significantly to the vehicle's overall safety, reliability, and efficiency, highlighting the importance of checking them during an inspection. The other options do not include the complete array of necessary fluids, thereby overlooking some crucial aspects of vehicle safety.
