Defensive Tactics Practice Test 2026 – Complete Exam Prep Guide

The main idea is that any force used on an inmate must be limited to what is reasonably necessary to achieve a legitimate safety or security objective. In the field, staff are trained to assess the threat and apply only the minimum amount of force required to protect themselves, other people, and the environment, or to regain control of a situation. Force is appropriate when there is an immediate risk of harm or a clear need to restore order, and it should be proportional to the threat and stopped as soon as the situation is under control.

This is why the best answer is that physical force may be applied only when and to the extent that it is reasonably necessary. It reflects both necessity and proportionality. The other options aren’t correct because force isn’t something you can use at any time with supervisor approval, nor is it limited to a written order, and there are circumstances where force is legitimately required to prevent harm.
