When people ask what a DUI will do to them, they rarely mean the fine. They mean their job, their nursing or teaching license, their rifle, their kids. Some of those worries are well founded and some are not. This page separates the two, with the source for each. It is part of our Montana DUI Guide.
At a Glance
| Area | Short answer |
|---|---|
| Firearms | A first, second, or third DUI is not a federal firearm prohibition. A felony DUI is. |
| Hunting and fishing | We found no Montana statute tying a DUI to loss of hunting, fishing, or trapping privileges. |
| Professional licenses | A conviction is not an automatic bar to a Montana occupational license, but a board can consider it. |
| Background checks | The conviction is a public record. Montana limits what a consumer reporting agency may report after 7 years. |
| Parenting plans | Chemical dependency or chemical abuse by a parent is a listed best-interest factor. |
| Immigration | One DUI is treated very differently from two. A non-citizen needs immigration advice before any plea. |
| Federal student aid | Not affected by a DUI conviction. Incarceration is what limits eligibility. |
Firearms
The federal firearm prohibition applies to a person convicted of "a crime punishable by imprisonment for a term exceeding one year" (18 U.S.C. § 922(g)(1)). Federal law excludes from that phrase a state offense classified as a misdemeanor and punishable by two years or less (18 U.S.C. § 921(a)(20)). A first, second, or third Montana DUI is punishable by a maximum of 6 months or 1 year (MCA § 61-8-1007), so it is not a prohibiting conviction.
A felony DUIunder MCA § 61-8-1008 is a prohibiting conviction on its face. Montana's own unlawful-possession statute is much narrower than the federal one and does not list DUI (MCA § 45-8-313), but the federal law applies in Montana regardless. Whether and when rights can be restored after a felony is a question to take to an attorney, not to assume.
Two smaller points. At the initial appearance in any criminal case, a Montana judge must tell the defendant that a conviction may result in the loss of firearm rights (MCA § 46-7-102), so hearing that warning does not mean it applies to your charge. And a concealed weapon permit has its own eligibility rules, including one about charges that are still pending (MCA § 45-8-321).
Hunting and Fishing
Montana's fish and wildlife code suspends privileges for fish and game violations. We searched Title 87 and found no provision that takes away hunting, fishing, or trapping privileges because of a DUI conviction. The connection is indirect: a felony DUI is a federal firearm prohibition. A sentencing judge can also impose conditions on a sentence, so read your judgment.
Professional and Occupational Licenses
Montana law starts from a policy of rehabilitation. Criminal convictions "shall not operate as an automatic bar to being licensed to enter any occupation," and a licensing authority may not refuse a license solely because of a previous conviction. It may deny one where the offense relates to the public health, welfare, and safety as it applies to that occupation and the applicant has not been sufficiently rehabilitated (MCA § 37-1-203). Completing probation without a new conviction is evidence of rehabilitation (MCA § 37-1-205).
For boards under the state's uniform licensing act, unprofessional conduct includes a conviction for a crime relating to or committed during the practice of the profession, and use of alcohol or drugs to the extent that it impairs the person in performing licensed duties (MCA § 37-1-316). An off-duty DUI does not automatically fit either, but each board has its own rules, and a board may require licensees to report a conviction within a set time. Teachers are governed separately by the Board of Public Education (MCA § 20-4-110).
The practical advice is the same for a nurse, a teacher, a pilot, a real estate agent, or a contractor: find out what your board requires before the case is resolved, because the exact conviction and the reporting deadline both matter. A commercial driver faces a separate set of rules, covered on our CDL DUI page.
Employment and Background Checks
- The record is public. Convictions, court records, initial arrest records, and booking photographs are public criminal justice information (MCA § 44-5-103(13)), with no restrictions on dissemination (MCA § 44-5-301).
- Montana limits commercial background reports. A consumer reporting agency may not report a record of arrest or conviction that is more than 7 years old, measured from disposition, release, or parole (MCA § 31-3-112). Federal law by itself has no such limit for convictions.
- That limit is not sealing. It governs what a reporting agency puts in a report. It does not remove the court record or the driving record.
- Jobs that involve driving are affected most directly, through the license suspension and the employer's insurer.
Our page on how long a DUI stays on your record covers the lookback period and expungement.
Parenting Plans and Custody
A Montana court sets a parenting plan according to the best interest of the child, and the factors it may consider include "chemical dependency ... or chemical abuse on the part of either parent" (MCA § 40-4-212(1)(g)). A DUI is not on that list by name, and one arrest is not a finding of dependency. But it is evidence the other parent can offer, and a DUI with a child in the vehicle is treated far more seriously, in both courts. See our pages on DUI with a child passenger and child custody and parenting plans.
If you have an open family case, or expect one, tell your defense attorney. What is said in the criminal case, and the conditions you agree to, can be used in the other.
Immigration
For a non-citizen, the consequences are a matter of federal immigration law and are outside what a criminal defense lawyer can fully advise on. Three published points show why advice is needed early:
- Under the USCIS Policy Manual, two or more DUI convictions during the relevant period create a rebuttable presumption that an applicant lacks good moral character.
- The State Department's Foreign Affairs Manual allows a visa to be revoked based on a DUI arrest within the previous five years, without a conviction.
- Before accepting a guilty plea, a Montana court must advise that a plea might result in deportation, exclusion, or denial of naturalization for a non-citizen (MCA § 46-12-210).
Travel
Canada is the consequence most Montanans do not see coming. A single DUI can make a person inadmissible. Our page on traveling to Canada after a DUI explains the rules and the ways to be allowed in.
Insurance
A DUI affects what you pay for auto insurance and can affect whether a policy continues. Montana limits how long an insurer may use a driving record against you. Our page on what a DUI costs has the details.
