Which cab component is checked to ensure unobstructed operation and visibility?

• A. Windshield wipers and washer system
• B. Fuel cap tightness
• C. Brake pedal pad material
• D. Radiator cap color

Answer: (A)

Keeping the windshield clear is essential for safe driving, so the windshield wipers and washer system are checked to ensure you can maintain unobstructed visibility in rain, snow, or dirt. This involves inspecting the wiper blades for wear, making sure they sweep the entire windshield without skipping or streaking, and confirming the washer system sprays fluid properly and has enough fluid to help wipe away grime. If any part of this system isn’t working, visibility is compromised and safety is reduced.

The other components don’t affect visibility. A fuel cap tightness is about preventing leaks and fumes, not clearing the view. Brake pedal pad material relates to braking performance, not what you see through the windshield. Radiator cap color has no impact on visibility or the ability to see the road.
