Stand Your Ground / Self-Defense Laws in Idaho

Idaho does not pull any punches when it comes to their iteration of stand-your-ground laws. Idaho broadly justifies lethal force when it is used to prevent the threat of death or great bodily injury against any person or to stop any forcible felony.

Laudable even among advocate self-defense states is that Idaho statutes take great pains to explain and instruct potential judges and juries under what auspices such actions might be appraised.

Specifically, the benefit of hindsight is not allowed, and judging a defender’s actions when lethal force is used and it is codified in the law the only the appearance of a lethal threat is required for a defender to respond accordingly, not the genuine presence of such a threat.

In any case, there is no duty to retreat so long as a person has a right to be where they are.

If that sounds a little confusing, don’t worry; we will explain everything in the rest of this article, and you’ll be pleased to know that it is actually a very good thing for civilians who might have to protect themselves and their loved ones in extremis.

You will also find the precise text of the current state statutes on the subject at the end of this article for your review, and as always we suggest you get very comfortable with them.

What You Need to Know

  • Idaho justifies an appropriate level of force, including lethal force, if it is necessary to prevent a threat of like kind, meaning any threat of death or great bodily injury.
  • Idaho also allows for lethal force to be employed if it is necessary to halt or prevent any commission of a forcible felony.
  • Idaho codifies that any person acting justly has no right to retreat from any place they have a right to be if the use of force is necessary to prevent harm.
  • Idaho features a statute declaring the legislature’s intent to incorporate both Castle Doctrine and stand-your-ground laws along with jury instructions into the relevant chapters.

General Provisions

Idaho is a strong proponent of self defense for civilians, and even a cursory reading of the law will reveal this to anyone.

Idaho makes way for the use of lethal force and self-defense by providing a justification for homicide, stating that homicide is justifiable when committed by anyone so long as it is done in order to resist any attempt to stop the murder of any person, the infliction of great bodily harm on any person, or the commission of any felony.

They further state that when it is done in defense of habitation, a place of business or an occupied vehicle against a person violently or tumultuously attempts to enter any of those places of occupation.

Of particular interest, Idaho has a statute in Section 19 declaring the intent of the legislature to integrate castle doctrine and stand-your-ground laws throughout, along with providing instruction to juries in certain parts of the chapter.

While many states have incorporated both castle doctrine and stand-your-ground laws into their statutes, only a handful of states take the time too plainly and boldly declare this intent in those same law books. How about a round of applause for Idaho?

Elsewhere in the section, the statutes state that resistance by any threatened party is permissible so long as the person about to be injured provides that resistance to prevent an offense against themselves or their family and if they further may use any such degree and extent of force judge reasonably necessary to prevent said injury.

“Reasonable” is further qualified as being determined from the viewpoint of a reasonable person placed in that same set of circumstances, and only seeing and knowing what the subject saw and knew without any such benefit of hindsight.

If that sounds laborious and circuitous, consider that one of the many flaws of our legal system is that the people doing the judging of the defendant during a trial concerning self-defense get to consider and appraise their actions the defendant took at their leisure, whereas the defendant had to assess, make a decision and then act in an instant.

This is certainly a worthwhile reminder for judges and juries alike to consider the events in their totality.

Lastly, the Idaho laws codify that a person acting in defense of themselves or someone else does not need to wait until they ascertain whether or not any apparent danger is in fact real.

Any such person confronted with danger has the right, under law, to act upon appearances such as would influence the action of any reasonable person.

Consider what you would do if confronted with a mugger who had a shiny knife leveled at your belly, or appeared to be pointing a gun at you through his coat pocket:

In Idaho, you could (rightly) act without waiting to ascertain whether or not the knife was actually real or even sharp, or before learning whether there was actually a gun inside his pocket or he was bluffing.


Idaho places no meaningful restrictions on the use of lethal force in self-defense beyond the standard of reasonable care, and that a person who provokes an encounter may not claim self-defense unless they have made a good-faith effort to extricate himself from the situation before they are faced with a legitimate threat to their life or limb.


Idaho is one of the leading stand-your-ground states, possessed of multiple statutes affirming citizens’ rights to use lethal force in defense of a similar threat, and further instructing juries as to what they may consider under the circumstances should such a matter make it to court.

Defenders in Idaho have no obligation to retreat so long as they are not committing a crime, and are otherwise in any place they legally, lawfully have a right to be.

Any other person, in aid or defense of the person about to be injured, may make resistance sufficient to prevent the offense.
