Which key component is NOT typically inspected during an exterior inspection?

During an exterior inspection, the focus is primarily on components that are visible from outside the vehicle and play a critical role in ensuring safe operation. Tires, mirrors, and windows are all essential elements for vehicle safety and visibility. Tires are inspected for proper inflation, tread depth, and overall condition to ensure they are safe for driving. Mirrors are crucial for visibility and lane changes, while windows must be intact and clean for clear sightlines.

Engine oil level, however, is an internal component that cannot be assessed from outside the vehicle. It requires opening the hood and checking the dipstick, which falls outside the scope of an exterior inspection. Thus, understanding which components are visible and relevant during an exterior check helps clarify why engine oil level is not included in this specific inspection type.
