Which of the following would need to be checked prior to placing a truck-tractor into service after replacing the hood?

• A. Windshield wiper blade condition
• B. Headlight aim adjustment
• C. Air filter
• D. Fuel filter

Answer: (B)

Replacing the hood can shift or disturb the front-end alignment, especially the headlight assemblies. Before placing the truck-tractor back into service, it’s essential to verify that the headlights are aimed correctly. Proper headlight aiming ensures the beam pattern illuminates the road at the right height and distance without blinding oncoming drivers, which is a safety and regulatory requirement after any front-end work. While windshield wiper blades, air filter, and fuel filter are important for overall visibility and engine performance, they aren’t specifically affected by hood replacement and don’t need to be checked as part of the immediate reassembly verification.
