Which is a valid suspension indicator to check during a walk-around?

Answer: A — Uneven ride height

Uneven ride height is a clear sign to check for suspension problems during a walk-around. If one corner sits noticeably lower than the others, it can indicate a damaged or weak component such as a broken or sagging leaf spring, a failed shock absorber, a leaking air bag in an air-ride suspension, or an overload on one axle. This kind of imbalance affects ride quality, stability, and safe handling, so spotting it before driving is essential. To check, observe the vehicle on a level surface and compare each corner for consistent clearance between the tires and the wheel wells; look for sagging, leaning, or gapping that suggests a problem. If you see this, it should be noted and the vehicle should not be operated until repaired. The other choices don’t assess suspension health: bright headlights relate to lighting, a clean windshield to visibility, and a full fuel tank affects weight distribution but isn’t a reliable indicator of suspension condition.
