Yes—you can. Idaho’s Constitutional Carry law applies to vehicles, meaning law-abiding citizens can carry a concealed firearm in their car without a permit.

The relevant statute is Idaho Code § 18-3302(4)(c), which lists exemptions to the concealed carry license requirement. It states:

“Any deadly weapon concealed in a motor vehicle;”

This exemption means that if your firearm is concealed inside your vehicle, you’re not required to have a concealed weapons license—as long as you’re legally allowed to possess a firearm.

Constitutional Carry in Idaho applies at age 18. In 2020, the Idaho Legislature expanded permitless carry to include adults 18 and older—as long as they meet all legal qualifications.

It’s important to distinguish between possession and purchase:

• Possession: Idaho law allows individuals 18 and older to carry a concealed handgun without a permit.
• Purchase: Federal law still requires individuals to be 21 or older to buy a handgun from a licensed dealer (FFL).

Relevant Statutes:

• Idaho Code § 18-3302(4)(f)(i):
• Idaho Code § 18-3302(4)(f)(iii) adds a key qualifier.

This means that Constitutional Carry does not apply to anyone who would be disqualified from obtaining a Concealed Weapons License. Disqualifications include felony convictions, certain mental health adjudications, drug abuse, and more.

View the full list of disqualifications in Idaho Code § 18-3302(11)(b–n).

No—it applies to all U.S. citizens. Idaho’s Constitutional Carry law allows any qualifying U.S. citizen—or current member of the U.S. Armed Forces—to carry a concealed handgun without a permit in Idaho.

Under Idaho Code § 18-3302(4)(f)(ii), one of the key exemptions to the concealed carry license requirement is:

“Is a citizen of the United States or a current member of the armed forces of the United States;”

This means you do not have to be an Idaho resident to carry concealed under Idaho’s Constitutional Carry law.

However, Constitutional Carry only applies if you’re legally eligible to obtain a Concealed Weapons License. That’s spelled out in Idaho Code § 18-3302(4)(f)(iii):

“Is not disqualified from being issued a license under paragraphs (b) through (n) of subsection (11) of this section.”

Disqualifications include:

• Felony convictions
• Certain violent misdemeanors
• Drug abuse or addiction
• Mental health adjudications
• Dishonorable military discharge
• Active protection orders

Yes. Idaho recognizes all valid concealed weapons permits issued by other U.S. states.

According to the Idaho State Police:

“Idaho acknowledges the validity of all other states’ concealed weapons licenses/permits. Non-residents carrying a concealed weapon in Idaho must possess a valid state-issued concealed weapons license/permit from the state where it was issued.”

What If My Permit Is Expired?

Even if your out-of-state permit has expired, you may still legally carry concealed in Idaho—as long as you meet the requirements under Idaho’s Constitutional Carry law:

• You’re at least 18 years old
• You’re a U.S. citizen or active-duty military
• You’re not disqualified from obtaining an Idaho Concealed Weapons License

Idaho proudly supports permitless carry for law-abiding citizens. Whether you’re visiting from Texas, Tennessee, or anywhere in between, your rights don’t stop at the state line.

Yes. Idaho is a Stand Your Ground state with no duty to retreat when defending yourself or others in a place you have a legal right to be.

For decades, Idaho’s Stand Your Ground principle was rooted in case law dating back to 1904. But in 2018, the Idaho Legislature codified this right into statute—making it crystal clear.

Idaho Code § 19-202A(3):

“In the exercise of the right of self-defense or defense of another, a person need not retreat from any place that person has a right to be. A person may stand his ground and defend himself or another person by the use of all force and means which would appear to be necessary to a reasonable person in a similar situation and with similar knowledge without the benefit of hindsight.”Read the full statute here

⚠️ Important Caveat

This provision does not apply to incarcerated individuals interacting with jail or prison staff acting in their official capacity.

And while Idaho law protects your right to defend yourself, legal consequences can still arise depending on the situation. If you’ve used force in self-defense, consult an attorney immediately to protect your rights.

No. Idaho law prohibits cities and counties from creating their own firearm regulations. This is known as firearm preemption—and it ensures that gun laws are uniform across the state, from Boise to Bonners Ferry.

Idaho Code § 18-3302J: Firearm Preemption

“Except as expressly authorized by state statute, no county, city, agency, board or any other political subdivision of this state may adopt or enforce any law, rule, regulation, or ordinance which regulates in any manner the sale, acquisition, transfer, ownership, possession, transportation, carrying or storage of firearms or any element relating to firearms and components thereof, including ammunition.” —Idaho Code § 18-3302J

⚠️ Limited Exceptions

Local governments can regulate the discharge of firearms (e.g., shooting within city limits), but they cannot regulate possession, carry, or ownership. Even those discharge ordinances must include exceptions for:

• Self-defense
• Lawful hunting
• Sport shooting ranges
• Target shooting on public land

Whether you’re in a liberal city like Boise or a conservative town like Grangeville, your Second Amendment rights are protected equally. No patchwork. No confusion. Just freedom.

No. Idaho does not require a permit to purchase a firearm—whether it’s a handgun, rifle, or shotgun.

This reflects Idaho’s strong support for Second Amendment rights and its commitment to keeping firearm laws simple and accessible for law-abiding citizens.

If you are purchasing a firearm through an FFL dealer, then the typical paperwork from the ATF and the background check are still going to happen.

✅ Yes—Idaho law does not prohibit carrying a firearm in a church. Churches are treated like any other private property under state law, meaning they can set their own policies regarding firearms.

🔒 If a church has a posted sign or internal policy banning firearms, it’s not a criminal violation to carry—unless:

• You’re asked to leave and refuse
• You’re knowingly violating a posted policy and remain on the premises

In that case, you could be charged with criminal trespass under Idaho Code §18-7008, since the church has the right to control access to its property.

🛐 Bottom line: You can legally carry in a church unless they ask you to leave or have a policy you knowingly violate.

The short answer: It depends—and it’s complicated.

Idaho’s Constitution gives the state legislature sole authority to regulate concealed weapons, not open carry. That means, in theory, open carry is not prohibited by law on public campuses. However, the legal landscape is murky. Courts haven’t clearly ruled on how Idaho’s firearm preemption law interacts with university policies, especially when public institutions act like private entities by banning firearms on property they control.

👨‍🎓 For students and visitors, concealed carry is allowed only if you hold an Enhanced Concealed Weapons License under Idaho Code §18-3309. Even then, there are strict limitations:

• You cannot carry in dormitories or residence halls
• You cannot carry in public entertainment facilities with 1,000+ seats (e.g., stadiums, arenas, theaters)
• Universities may still enforce policies that restrict firearms in other areas, creating confusion and potential legal risk

🛑 Bottom line: Idaho’s Campus Carry law is full of carve-outs and contradictions. We believe it needs a major overhaul to restore clarity and remove restrictions. Public property should not be treated like private property when it comes to constitutional rights.

Yes—but only if they’re federally registered.

Idaho does not ban machine guns outright. In fact, the state defers to federal law, which means:

• You can legally own a machine gun in Idaho if it was manufactured before May 19, 1986, and is properly registered under the National Firearms Act (NFA).
• You must go through the ATF approval process, which includes:
  • A $200 tax stamp
  • Background check
  • Federal registration
• Idaho law prohibits minors from possessing automatic weapons and requires compliance with federal regulations.

Bottom line: Machine guns are legal in Idaho—but only for those who follow the federal rules. No shortcuts. No post-1986 full-autos.

We don’t agree with any of these restrictions, but it is what current law is in Idaho and the United States of America.

Yes. Suppressors (also known as silencers) are legal to own and use in Idaho, provided you comply with federal regulations under the National Firearms Act (NFA).

To legally possess a suppressor, you must:

• Be at least 21 years old to purchase from a licensed dealer (or 18 to possess via lawful transfer or trust)
• Submit an application to the ATF, including fingerprints, a photo, and a $200 tax stamp
• Pass a federal background check and not be prohibited from owning firearms

Idaho does not impose additional state-level restrictions beyond federal law. In fact, suppressors are also legal for hunting across a wide range of game species, making them a popular choice for hearing protection and noise reduction in the field.

For Idaho-made suppressors that remain within state borders, Idaho Code §18-3315A asserts they are not subject to federal interstate commerce regulation—but federal law still applies in practice.

We get asked this question frequently, especially since other states have passed similar laws.

For Idaho-made suppressors that remain within state borders, Idaho Code §18-3315A asserts they are not subject to federal interstate commerce regulation. However, federal law still applies in practice—and ignoring it can carry serious consequences.

Other citizens in states like Texas have tried to rely on similar laws and ended up facing federal prosecution. In Paxton v. Dettelbach (2024), Texas residents and the state Attorney General challenged federal suppressor regulations, arguing that devices made and kept in-state should be exempt. The Fifth Circuit Court of Appeals rejected the case, affirming that states cannot nullify federal law, and that making a suppressor without complying with federal requirements remains a federal crime punishable by up to 10 years in prison.

Our advice: consult an attorney. While we want this gross infringement gone, we do not recommend having a suppressor made in Idaho and assuming the federal government won’t come for you. The stakes are too high, and the law is too unforgiving.

Yes. Idaho is one of the few states that still allows firearms inside its Capitol.

Citizens, lobbyists, and lawmakers regularly carry—both openly and concealed—inside the building. The Idaho Second Amendment Alliance has hosted rallies inside and outside the Capitol with attendees carrying handguns and long guns. There are no restrictions.

It depends on where you are.

Federal law prohibits carrying a firearm past the TSA security checkpoint—this includes the gate area, jet bridges, and any part of the terminal designated as a “sterile area.” Violating this can result in serious federal penalties.

However, outside of security, Idaho law does not restrict lawful carry in public areas of the airport. That means if you’re picking someone up, dropping someone off, or walking through ticketing and baggage claim, you’re generally good to go—assuming you’re legally carrying under Idaho law.

If you’re traveling, you must check your firearm properly:

• It must be unloaded
• Locked in a hard-sided case
• Declared at the airline counter

Bottom line: In Idaho, you can carry at the airport—just don’t try to bring it through TSA.

For the most part, yes. Idaho’s strong firearm preemption laws prevent cities and counties from regulating possession on public property.

However, there are exceptions. Firearms are prohibited in courthouses, jails, and detention facilities. Some secure areas within government buildings may also restrict carry—especially beyond security checkpoints.

Always check for posted signs or local rules, but in general, Idaho respects your right to carry.

No. Idaho law explicitly prohibits firearm registration.

Constitutional Protection

Article I, Section 11 of the Idaho Constitution states:

“No law shall impose licensure, registration or special taxation on the ownership or possession of firearms or ammunition. Nor shall any law permit the confiscation of firearms, except those actually used in the commission of a felony.” —Idaho Constitution Article I, § 11

This isn’t just policy—it’s a constitutional firewall against registration schemes, licensing mandates, and gun taxes.

What It Means for Idahoans

• No registration of firearms—ever
• No licensing of gun owners
• No special taxes on guns or ammo
• No confiscation, unless the firearm was used in a felony

Idaho stands firm: Your right to keep and bear arms is protected from bureaucratic overreach.

No. Idaho does not have an “assault weapons” ban like those enacted in several Democrat-controlled states.

It’s important to note that the term “assault weapon” is often used by anti-gun activists to target commonly owned rifles, shotguns, and handguns based on cosmetic features rather than functionality. This label is designed to make standard firearms appear more dangerous and justify sweeping bans.

You can legally possess, purchase, and use magazines of any size—including those holding more than 10, 15, or even 30 rounds. Idaho law does not define or regulate “large-capacity magazines,” and there are no state-level limits on the number of rounds a magazine can hold.

This applies to:

• Handguns
• Rifles
• Shotguns
• Detachable and fixed magazines

💡 However, always be aware of federal laws and traveling across state lines. Many other states—including California, New York, and Colorado—do restrict magazine capacity, and possession could be a criminal offense there.

Short answer: Generally, no. But there’s one exception.

Idaho’s Constitution explicitly prohibits firearm confiscation—except when the firearm was used in the commission of a felony.

“Nor shall any law permit the confiscation of firearms, except those actually used in the commission of a felony.” — Idaho Constitution, Article I, Section 11

This means the state legislature cannot pass a law that allows firearm confiscation outside of that narrow exception.

But here’s where things get murky:

• 🔹 “Confiscation” isn’t defined anywhere in Idaho Code.
• 🔹 There’s no Idaho case law we have been able to find that clarifies what counts as confiscation.

This ambiguity raises serious questions—especially if a federal Red Flag law (Extreme Risk Protection Order) were enacted:

• Could Idaho courts interpret a Red Flag order as not being “confiscation” if the firearm is transferred to a third party (like a family member) instead of being seized by the government?
• Could the legislature pass a Red Flag-style law that avoids the word “confiscation” but still forces you to surrender your firearms?
• Would courts uphold such laws as constitutional under Idaho’s Article I, Section 11?

These are unanswered legal questions. Until Idaho defines “confiscation” in statute or case law, the scope of this constitutional protection remains uncertain.

Short answer: No. Idaho does not have a Red Flag law, commonly called Emergency Risk Protection Orders.

In theory, Idaho’s Constitution (Article 1 Section 11) should prohibit Red Flag laws because the state constitution bans firearm confiscation—except when the firearm was used in the commission of a felony.

“Nor shall any law permit the confiscation of firearms, except those actually used in the commission of a felony.” — Idaho Constitution, Article I, Section 11

This means the state legislature cannot pass a law that allows firearm confiscation outside of that narrow exception.

But here’s where things get murky:

• 🔹 “Confiscation” isn’t defined anywhere in Idaho Code.
• 🔹 There’s no Idaho case law we have been able to find that clarifies what counts as confiscation.

This ambiguity raises serious questions—especially if a federal Red Flag law were enacted:

• Could Idaho courts interpret a Red Flag order as not being “confiscation” if the firearm is transferred to a third party (like a family member) instead of being seized by the government?

• Would courts uphold such laws as constitutional under Idaho’s Article I, Section 11?

These are unanswered legal questions. Until Idaho defines “confiscation” in statute or case law, the scope of this constitutional protection remains uncertain.

Yes—but with limits. Idaho law does not prohibit you from entering a private business with a firearm, even if there’s a “No Guns” sign posted. These signs do not carry the force of law in Idaho.

However, private property rights still apply. If a business owner or employee notices you’re carrying and asks you to leave, you must comply. Refusing to leave could result in a trespassing charge, which is a misdemeanor under Idaho law.

Legal Summary

• “No Guns” signs are not legally binding in Idaho.
• Businesses can set their own policies and ask you to leave.
• If you refuse, you could be charged with criminal trespass.
• Idaho Code § 18-3302J protects your right to carry, but it does not override private property rights.

No. Idaho does not have a “Duty to Inform” law.

In some states, gun owners are legally required to notify law enforcement if there’s a firearm in the vehicle during a traffic stop. Idaho is not one of those states. You are not legally obligated to disclose that you have a firearm in the car.

That said, gun owners often debate whether it’s wise to voluntarily inform an officer. Here’s how that plays out:

• Some choose to inform as a courtesy. If you do, the officer may ask where the firearm is and request that it remain untouched.
• Others choose not to, believing it may escalate tension or cause unnecessary concern.

The Idaho reality? Most officers assume there’s a gun in the vehicle. With one of the highest firearm ownership rates in the country, it’s not unusual for Idahoans to travel armed. Officers know that—and they’re trained for it.

Bottom line: You’re not required to say anything. Whether you do or don’t is a personal choice. Just be calm, respectful, and keep your hands where they can be seen.

Yes. Idaho law does not prohibit carrying a firearm—open or concealed—into a bar or establishment that serves alcohol.

However, you cannot concealed carry while intoxicated. That’s a key legal boundary. Idaho Code § 18-3302B makes it illegal to conceal carry a firearm while under the influence of alcohol or drugs.

Legal Summary

• Carrying into a bar is legal.
• Carrying concealed while intoxicated is illegal.
• Businesses may still ask you to leave or prohibit firearms on their premises.
• Refusing to leave when asked could result in a trespassing charge.

Yes—non-Idaho residents can legally purchase rifles and shotguns from federally licensed dealers (FFLs) in Idaho, as long as the sale complies with federal law, Idaho law, and the buyer’s home state laws.

The relevant Idaho statute is Idaho Code § 18-3315, which states:

“Residents of a state other than the state of Idaho may purchase rifles and shotguns in Idaho, provided that such residents conform to the applicable provisions of the federal gun control act of 1968, and regulations thereunder, and provided further, that such residents conform to the provisions of law applicable to such purchase in Idaho and in the state in which such persons reside.”

However, handguns are treated differently under federal law. FFLs are prohibited from selling handguns over the counter to non-residents.

Instead, the handgun must be shipped to an FFL in the buyer’s home state, where the final transfer and background check are completed.

Idaho residents can sell a handgun via a private party sale to another Idaho resident without going through an FFL, however, a private party sale to an out-of-state resident is still prohibited under the Gun Control Act (which is an infringement).

No. Idaho law does not impose special requirements on non-residents traveling with firearms.

Unlike restrictive states nearby—such as Washington or Oregon—Idaho is a Constitutional Carry state, and that freedom extends to visitors. Whether your firearm is loaded or unloaded, locked or unlocked, you’re free to carry it in your vehicle or on your person, provided you’re legally allowed to possess firearms under federal and Idaho law.

There’s no need for a permit, registration, or special handling. Just be a responsible firearm owner.

Yes. Idaho’s Constitution explicitly protects the right to keep and bear arms in Article I, Section 11. It reads:

“The people have the right to keep and bear arms, which right shall not be abridged; but this provision shall not prevent the passage of laws to govern the carrying of weapons concealed on the person nor prevent passage of legislation providing minimum sentences for crimes committed while in possession of a firearm, nor prevent the passage of legislation providing penalties for the possession of firearms by a convicted felon, nor prevent the passage of any legislation punishing the use of a firearm. No law shall impose licensure, registration or special taxation on the ownership or possession of firearms or ammunition. Nor shall any law permit the confiscation of firearms, except those actually used in the commission of a felony.” —Idaho Constitution Article I, Section 11

What It Means

• Idaho’s Constitution goes beyond the Second Amendment, adding protections against:
  • Licensure or registration of firearms
  • Special taxes on guns or ammo
  • Confiscation, except in felony cases
• It also allows for laws governing concealed carry, sentencing enhancements, and felon possession penalties.

Yes. Idaho is proudly an Open Carry state, and you do not need a permit to openly carry a firearm—whether you’re a resident or just passing through.

In fact, Idaho’s Constitution explicitly protects this right. Article I, Section 11 allows the legislature to regulate concealed weapons—but not open carry. That means the state has no authority to require permits, registration, or special taxation for openly carried firearms.

As long as you’re legally allowed to possess a firearm, you’re free to carry it openly in most public places across Idaho.
