Are vehicles with aftermarket modifications always subject to failing inspection?

Vehicles with aftermarket modifications are not automatically subject to failing inspection. The key factor lies in whether those modifications violate established safety standards. For instance, if an aftermarket modification enhances safety or complies with regulations, it can pass inspection without issue. Conversely, modifications that impair the vehicle’s safety performance, such as alterations to critical components like brakes or steering systems, can lead to failures.

This option emphasizes the principle that inspections focus on safety compliance rather than merely the presence of modifications. Options suggesting that all modifications always result in failure overlook this crucial distinction between safe and unsafe alterations. Additionally, the concept that modifications are never considered contradicts the inspection's purpose to ensure vehicle safety, highlighting the necessity of evaluating the nature and impact of the modifications. Lastly, stating that only visible modifications are considered ignores the possibility of hidden alterations that may also affect compliance with safety standards.
