During a pre-trip inspection, which wheel or rim condition can indicate a safety problem?
Correct answer: A – Rust trails around wheel nuts
Rust trails around wheel nuts can indicate that the nuts are loose and require a tightness check. The Wyoming CDL manual also identifies missing clamps, spacers, studs, or lugs and mismatched, bent, or cracked lock rings as dangerous. Wheels or rims repaired by welding are not considered safe.
