What is the purpose of looking under a truck during vehicle inspections?

• A. To count the axles
• B. To verify operator license
• C. To check tire tread depth
• D. To inspect for fluid leaks

Answer: (D)

Looking under a truck during inspections is about spotting fluid leaks. Drips, stains, or puddles can reveal leaks from the engine, cooling system, fuel system, transmission, or hydraulic lines. Detecting these early helps prevent bigger problems, reduces fire and environmental hazards, and signals needed maintenance before the vehicle is used. Other checks touch on different aspects: counting axles or verifying licenses are not done from beneath the truck, and tire tread is assessed on the tire surface, not under the vehicle.
