What types of fluids are checked during a vehicle inspection?

• A. Only engine oil and transmission fluid
• B. Engine oil, transmission fluid, brake fluid, and coolant
• C. Brake fluid, windshield washer fluid, and motor oil
• D. Only coolant and fuel levels

Answer: (B)

Fluids checked during a vehicle inspection are the ones that keep the car’s essential systems operating safely: engine oil, transmission fluid, brake fluid, and coolant. Engine oil provides lubrication to reduce wear; transmission fluid keeps the transmission shifting smoothly and helps manage heat; brake fluid is crucial for the hydraulic braking system to function properly; coolant prevents the engine from overheating and shows leaks or low levels that could cause damage. These four together cover lubrication, transmission operation, braking capability, and cooling, which is why that option is the best. The other choices omit one or more of these critical fluids, or include fluids not typically part of the standard inspection (such as windshield washer fluid or fuel level checks).
