Which of the following is considered a major infraction?

The choice concerning excessive charging is considered a major infraction because it involves overcharging customers for inspection services, which is not only unethical but also affects public trust and the integrity of the inspection process. This action can lead to financial harm for customers and undermine the regulatory framework that governs automobile safety inspections.

Maintaining proper ethical standards in charging for services is crucial to ensure transparency and fairness in the automotive inspection industry. Violating this principle can have significant repercussions, including sanctioning by regulatory bodies, loss of licensure, and legal consequences, thus categorizing it as a major infraction.

On the other hand, failure to display a permit, failure to mark inspection items, and maintaining a safe environment, while serious, do not carry the same level of direct financial implications or compromise the ethical standards as excessive charging does. These issues can typically be rectified through corrective actions and do not usually result in severe penalties compared to the ramifications of overcharging.
