A DUI will not automatically disqualify you from buying a gun, but it can under certain circumstances

A single DUI conviction does not trigger a federal firearms prohibition on its own. The federal background check system — the National when ready Criminal Background Check System, or NICS — does not flag DUI convictions as a reason to deny a gun purchase. However, a DUI can still block you from buying a gun if it results in a felony conviction, if it involves certain aggravating factors, or if your state has its own rules that go beyond federal law.

The key distinction is between a misdemeanor DUI and a felony DUI. Most first-time DUIs are charged as misdemeanors, which do not appear in NICS checks. A felony DUI — which typically requires a prior conviction, an accident causing injury, or a very high blood alcohol level — will show up and will result in a denial. Additionally, some states impose their own restrictions on gun ownership for people with DUI records, regardless of whether the conviction was a felony.

Key Takeaways

  • Federal law does not prohibit gun ownership based on a misdemeanor DUI alone, but a felony DUI will result in a NICS denial.
  • Some states impose additional restrictions on gun ownership for DUI convictions that do not exist under federal law.
  • A DUI that results in a conviction for a crime of violence or domestic violence can trigger a federal prohibition even if it is a misdemeanor.
  • The outcome depends on your state, the specific charges, and whether the conviction was a felony or misdemeanor.

When a DUI becomes a federal firearms prohibition

Federal law prohibits gun ownership for anyone convicted of a felony, defined as a crime punishable by more than one year in prison. It also prohibits ownership for anyone convicted of a misdemeanor crime of domestic violence. A DUI becomes a federal prohibition if it meets one of these two categories.

A felony DUI typically occurs when you have prior DUI convictions within a set timeframe — often five to ten years, depending on the state — or when the DUI involves an accident that injures or kills someone. Some states also charge a DUI as a felony if the driver's blood alcohol content was extremely high or if the driver was driving with a suspended license due to a prior DUI. Once a DUI is charged as a felony, NICS will flag it during a background check, and a licensed firearms dealer must deny the sale.

A misdemeanor DUI can also trigger a federal prohibition if it is classified as a crime of domestic violence — meaning the victim was a spouse, former spouse, dating partner, or family member. This classification depends on state law and the specific circumstances of the arrest. Not all states classify DUI as a domestic violence offense, and not all DUI arrests involve a domestic relationship, so this pathway is less common but does occur.

State-level restrictions that go beyond federal law

Several states impose their own gun ownership restrictions for people with DUI convictions, even when federal law does not. These state rules vary widely and are not always well-publicized, which means a person may pass a federal NICS check but still be prohibited under state law from possessing a firearm.

California, for example, prohibits gun ownership for anyone convicted of a DUI within the past ten years. New York imposes restrictions based on the circumstances of the DUI and whether it involved injury. Some states tie the restriction to driver's license suspension or revocation rather than the conviction itself. A few states have no additional DUI-related restrictions beyond federal law. Because these rules differ by state, the only reliable way to know whether your DUI affects your gun rights is to research your specific state's laws or consult a local attorney.

How the NICS background check process works for DUI records

When you attempt to buy a gun from a licensed dealer, the dealer submits your information to NICS, which searches federal and state criminal databases. NICS looks for convictions that fall into specific prohibited categories: felonies, domestic violence misdemeanors, certain restraining orders, and a few other narrow categories. A misdemeanor DUI that does not involve domestic violence will not appear as a match in most NICS searches.

However, NICS does not search every database uniformly. Some states report their DUI convictions more thoroughly than others, and some report only felonies. This means that even if your state has a DUI-related gun restriction, it may not show up in the NICS check if your state has not reported the conviction to the federal system. This is a gap in enforcement, not a legal loophole — if you know you are prohibited under state law, purchasing a gun anyway is still illegal.

If NICS denies your purchase, you receive a written reason for the denial. You can then request a correction if the information is wrong, or you can pursue other legal remedies depending on your state. The process for appealing a NICS denial varies by state and is often slow.

Felony versus misdemeanor DUI and what determines the charge

Whether a DUI is charged as a felony or misdemeanor depends on several factors. A first-time DUI with no injuries or property damage is almost always a misdemeanor. A second or subsequent DUI within a certain period — typically five to ten years — is often charged as a felony. A DUI that causes injury or death is usually a felony, regardless of prior convictions.

Some states also consider the driver's blood alcohol content, the driver's age, or whether the driver was driving with a suspended license. A few states have "habitual traffic offender" statutes that can elevate a DUI to a felony based on the number of traffic violations in a set period. The specific rules vary significantly by state, which is why two people with similar DUI circumstances might face different charges in different states.

What to do if you have a DUI and want to buy a gun

Start by determining whether your DUI was a felony or misdemeanor conviction. This information appears on your court documents and criminal record. If it was a misdemeanor, check your state's specific gun laws to see whether your state imposes additional restrictions. Many state attorney general websites have information about gun ownership restrictions, though the information is not always straightforward to find or clearly written.

If you are unsure, consult a local criminal defense attorney or a firearms attorney in your state. They can review your specific conviction and tell you whether you are prohibited under state law. This step is worth the cost, because purchasing a gun while prohibited is a federal crime that can result in up to ten years in prison.

If you are prohibited, some states allow you to petition for restoration of your gun rights after a certain period of time or after meeting specific conditions. The process and timeline vary by state. A few states do not allow restoration at all. An attorney in your state can advise you on whether restoration is possible in your situation.

Frequently Asked Questions

Will a DUI show up on a gun background check?

A misdemeanor DUI will not show up in the federal NICS background check. A felony DUI will show up and will result in a denial. Some states also report misdemeanor DUIs to their own databases, which may be checked during a state-level gun purchase process, so the answer depends on your state and whether your DUI was a felony.

Can I buy a gun if I have one DUI?

If your single DUI was a misdemeanor and your state does not have a separate DUI-related gun restriction, you can likely buy a gun under federal law. However, some states like California prohibit gun ownership for anyone with a DUI conviction within the past ten years, regardless of whether it was a felony. Check your state's laws or speak with an attorney to be certain.

What if my DUI was dismissed or reduced?

If your DUI was dismissed, it should not appear on your criminal record and should not affect a gun purchase. If it was reduced to a lesser charge like reckless driving, the outcome depends on whether that lesser charge triggers any gun restrictions in your state. Bring your court documents showing the dismissal or reduction to the firearms dealer.

Can I get my gun rights back after a DUI?

If your DUI was a felony, you may be able to petition for restoration of your gun rights after a certain period or after meeting specific conditions, depending on your state. Some states allow restoration; others do not. An attorney in your state can tell you whether restoration is possible and what the process requires.
