Question: 1 / 400

During a pre-trip inspection, which statement about checking wheels and rims is true?

Rust around wheel nuts indicates they are secured

Rust around wheel nuts may mean they are loose

During a pre-trip inspection, rust around wheel nuts is significant as it can indicate that the nuts are loose. When wheel nuts are properly secured, you typically won’t see rust forming around them; instead, they would be clean and dry. The presence of rust suggests moisture is trapped, which often points to movement or a lack of tightness, indicating a potential safety issue that needs addressing.

This information is crucial because loose wheel nuts can lead to wheel separation while driving, increasing the risk of accidents. Ensuring that wheel nuts are tight and free of rust is essential for vehicle safety. Other options do not correctly address the implications of rust at the wheel nuts or may misrepresent the condition of wheels and rims necessary for safe vehicle operation.
