Tennessee Law Enforcement Training Academy (TLETA) Activity Week Practice Test

The second cardinal rule emphasizes immediate control over the firing action by keeping your finger off the trigger until you are ready to fire. This directly reduces the chance of an accidental discharge during handling, loading, aiming, or any sudden movement. Even if you think the firearm is unloaded, the safest habit is to keep your finger outside the trigger guard until you have deliberate, conscious intent to shoot.

The other statements cover important safety practices as well—knowing what is behind and around your target to prevent collateral damage, and maintaining muzzle discipline so the gun isn’t pointed at something you’re not willing to destroy. Those are essential, but the rule that places finger discipline as the next, immediate safeguard is why this option is the best answer for the second cardinal rule.
