A DUI conviction closes doors you may not have known existed. You can lose your license, your job, your professional credentials, your ability to cross certain borders, and in some cases your right to own a firearm or to see your children on your own terms. What you can’t do with a DUI depends on the severity of the offense, whether it was a misdemeanor or a felony, and how recent it is, but the list is longer and lasts longer than most people expect.
Drive Without Restrictions
Losing your license is the most immediate consequence. First-offense suspensions typically run from a few months to a full year, and the length climbs sharply with repeat offenses, a high BAC, or a refusal to submit to chemical testing. The administrative suspension often runs alongside the criminal case as a separate process.
To get back on the road, you’ll almost certainly need to install an ignition interlock device. You blow a clean sample before the engine starts, and the device prompts random retests while you’re driving. Installation runs roughly $85 to $350, with monthly calibration and monitoring fees of $70 to $125, plus removal costs when the requirement ends. Most states also charge an administrative reinstatement fee before reactivating your license.
Some states let you apply for a restricted or hardship license during the suspension that permits driving to work, court-ordered programs, or medical appointments on approved routes and at approved times. There’s usually a mandatory waiting period before you can even apply, so expect a stretch with no driving privileges at all.
Keep a Commercial Driver’s License
If you drive for a living, a DUI is close to career-ending. Federal law sets the BAC threshold for commercial drivers at 0.04 percent, half the standard limit, and requires at least a one-year disqualification from operating a commercial vehicle after a first offense. If the vehicle was carrying hazardous materials, the minimum jumps to three years.1Office of the Law Revision Counsel. 49 USC 31310 – Disqualifications
A second alcohol-related violation results in a lifetime disqualification, reducible to no less than ten years under certain conditions. The disqualification applies even if the DUI happened in your personal vehicle.1Office of the Law Revision Counsel. 49 USC 31310 – Disqualifications Trucking, delivery, and bus companies don’t typically hold positions open for that long.
Keep Your Insurance Rate or Rent a Car
Your insurer will likely cancel or decline to renew your policy. New coverage comes at high-risk rates, roughly double what a driver with a clean record pays. Most states require you to file an SR-22 certificate with the DMV before reinstating your license. The SR-22 is a filing your insurer makes to prove you’re carrying the state-mandated minimum liability coverage, usually for at least three years. If your coverage lapses for even a day, the insurer notifies the state and your license is suspended again.
Rental cars become difficult. Major rental companies check driving records and most refuse to rent to anyone with a DUI within the last three to five years. Companies that will work with you may charge more or restrict which vehicles you can choose.
Work in Certain Jobs or Hold a Professional License
A DUI shows up on most employment background checks. The obvious problem is any job that involves driving, but the damage extends further. Employers in education, healthcare, law enforcement, and finance often treat a DUI as a signal about judgment and reliability, which can cost you an offer even when driving isn’t part of the role.
The harder hit lands on professionals who hold state-issued licenses. Licensing boards for nursing, teaching, law, aviation, and real estate require self-reporting of criminal convictions, and failing to disclose can bring worse penalties than the DUI itself. Board actions range from mandatory rehabilitation and probationary periods to suspension or revocation. A teacher can lose certification. A nurse can lose the ability to work. A lawyer can face disbarment.
Enlist in the Military or Hold a Security Clearance
A DUI doesn’t automatically bar you from military service, but it makes enlisting significantly harder. Most branches require a moral waiver, and getting one is far from guaranteed. The Air Force and Coast Guard grant waivers less frequently than the Army.
For service members and government employees with a clearance, a DUI triggers review under Guideline G of the federal adjudicative guidelines, which covers alcohol consumption.2Center for Development of Security Excellence. Adjudicative Guideline G – Alcohol Consumption Short Student Guide A single old DUI with evidence of changed behavior may survive the review. A recent conviction, or more than one, raises doubts that are hard to overcome, and the self-reporting obligation means your employer and the investigating agency will find out either way.
Travel Freely to Other Countries
A DUI can stop you at the border, and the United States doesn’t control that decision. The destination country’s immigration authorities do.
Canada
Canada is the strictest major destination for travelers with a DUI. After Canadian law increased the maximum penalty for impaired driving in 2018, even a single misdemeanor DUI from the United States can make you inadmissible for serious criminality.3Government of Canada. Convicted of Driving While Impaired
If you’re denied entry, the main options are applying for a Temporary Resident Permit, which carries a processing fee and no guarantee, or applying for individual rehabilitation. For less serious cases classified under ordinary criminality, you may eventually qualify for deemed rehabilitation if at least ten years have passed since you completed your sentence and you have no other convictions.4Government of Canada. Overcome Criminal Convictions
Other Destinations
Japan can deny entry to anyone who received a sentence of a year or more, even if suspended. A typical misdemeanor DUI with no jail time usually won’t trigger a problem, but attached drug charges tighten the standard. Mexico is generally less restrictive for a standard first offense; felony convictions involving injury, death, or multiple offenses within the past ten years carry a real risk of denial. Countries that require a visa may ask about criminal history on the application itself, and border officers everywhere have discretion to turn you away.
Trusted Traveler Programs
A DUI isn’t listed among the specific offenses that automatically disqualify you from TSA PreCheck, but TSA retains discretion to deny applicants based on convictions for “serious crimes” not on its published list.5Transportation Security Administration. Disqualifying Offenses and Other Factors Global Entry involves a more rigorous background investigation, and Customs and Border Protection has denied applications based on DUI convictions, particularly recent or repeated ones. There’s no bright-line rule, so you may pay the application fee and still be turned down.
Stay in the Country if You’re Not a Citizen
A single DUI is not automatically a deportable offense or a ground of inadmissibility under federal immigration law, but it can create problems through several indirect paths. Two or more convictions of any type, with combined sentences totaling five years or more, can make you inadmissible. A DUI involving drugs rather than alcohol may lead immigration authorities to investigate whether you’re inadmissible as a drug abuser. A DUI with a child in the vehicle could be charged as a deportable crime of child abuse. Even being charged, before any conviction, can result in a consulate revoking a non-immigrant visa.
For green card applicants, a single DUI arrest within the past five years, or two within the past ten, can prompt referral to a panel physician for an alcoholism evaluation. An unfavorable finding makes you inadmissible on health grounds. If you’re a non-citizen facing a DUI charge, talk to an immigration attorney before entering a plea. The criminal defense lawyer handling your case may not be weighing the immigration side at all.
Own a Firearm
A standard first-offense misdemeanor DUI does not affect your right to own firearms. The federal prohibition under 18 U.S.C. § 922(g) applies when the conviction is classified as a felony, meaning a crime punishable by imprisonment for more than one year.6Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
A DUI gets elevated to a felony most commonly when it involves serious injury or death, when a child was in the vehicle, when there are multiple prior DUI convictions, or when the BAC was dramatically above the legal limit. The threshold varies by state. Once you have a felony DUI, the federal firearm prohibition is permanent unless rights are restored through a pardon or a specific restoration process.7Bureau of Alcohol, Tobacco, Firearms and Explosives. Identify Prohibited Persons
Keep Custody or Adopt
Family courts decide custody based on the child’s best interests, and a DUI gives a judge reason to question your fitness. The weight depends on how recent the conviction is, whether it’s part of a pattern, and especially whether a child was in the vehicle. Multiple DUI convictions, or one with a child passenger, can result in restricted visitation or a shift in custody. Courts can impose supervised visitation, mandatory substance abuse treatment, or alcohol monitoring as conditions of custody. In contested disputes, expect the other parent’s attorney to use the conviction to argue you’re unfit, with the burden on you to show rehabilitation.
Adoption and foster care applications also suffer. Agencies run detailed background investigations, and a DUI, particularly a felony or one involving a child, can delay or derail an application. Many agencies require a waiting period of several years. Even an expunged record may surface, since agencies often access databases comparable to law enforcement’s.
Keep Scholarships and Student Housing
Federal student aid like Pell Grants and Stafford Loans is not affected by a standard DUI under current FAFSA rules. Drug charges attached to the offense can trigger a temporary loss of eligibility, and incarceration at the time of application causes its own problems.
Scholarships are where the damage lands. Athletic scholarships almost always include conduct clauses, and a DUI can get you suspended from the team and stripped of funding. Many merit-based and private donor awards include character requirements that a DUI violates, and some institutions reserve the right to revoke a scholarship after an arrest, not just a conviction. Students already enrolled face potential discipline under student codes of conduct, even for off-campus incidents: academic probation, loss of campus housing, mandatory counseling, or suspension. For applicants, a DUI that shows up during admissions can influence decisions at competitive programs and professional schools.
