Important: Most ordinary driver-licensing, traffic, DUI, implied-consent, and point-system rules are state-specific. Federal rules additionally govern subjects such as commercial-driver BAC standards and certain federal identity/REAL ID requirements. This page is a general reference and does not establish the law for every state.

Frequently Asked Questions (FAQ)
For ordinary adult drivers, every state has an illegal-per-se BAC threshold of 0.08% or lower, with Utah using 0.05%. NHTSA identifies 0.08% as the standard threshold in the other states. Commercial motor vehicle drivers are subject to a separate 0.04% federal/state regulatory framework, and drivers under 21 are subject to state zero-tolerance laws generally using a BAC of 0.02% or lower. DUI laws also vary by state and can prohibit impaired driving below the per-se BAC threshold.
A DUI-related arrest can lead the Department of State to prudentially revoke a nonimmigrant visa under its visa-revocation procedures when the applicable conditions are met; this should not be described as an automatic revocation of every visa after every DUI arrest. A visa revocation also does not by itself terminate a person's underlying U.S. immigration status while the person remains in the United States. DOS medical guidance can require a panel-physician evaluation for applicants with an alcohol-related arrest or conviction, including a single such event within the prior five years, but repeat-examination rules contain exceptions. Green Card holders should be analyzed separately because they are lawful permanent residents, not holders of a nonimmigrant visa.
An International Driving Permit is a standardized multilingual translation/permit used with the driver's license issued by the driver's home country. U.S. rules are state-specific: not every state requires an IDP, and the period during which a nonresident or new resident may drive on a foreign license varies by state. A person who becomes a state resident may be required to obtain a state driver's license under that state's residency and licensing rules. Check the DMV for the state where you will drive.
Many states assign points or other administrative consequences to specified traffic convictions, but there is no single nationwide point schedule. The number of points, look-back period, suspension thresholds, and insurance requirements vary by state and sometimes by driver or license class. A DUI may carry different point consequences depending on the jurisdiction. SR-22 or another financial-responsibility filing may be required in some states for certain violations, but it is not a universal consequence of accumulating points.
All states have implied-consent laws, but the precise trigger for a test request, the type of test covered, the consequences of refusal, and the administrative procedures vary by state. Refusing an authorized chemical test can result in a separate administrative driver's-license suspension or revocation even when the person is not ultimately convicted of DUI. The duration is not a universal 6-to-12-month period.
The Driver License Compact and Non-Resident Violator Compact are interstate agreements involving participating U.S. jurisdictions. Their membership is not identical and can change. Current AAMVA materials identify 44 DLC jurisdictions and 47 NRVC jurisdictions. Participating jurisdictions exchange certain traffic-conviction, suspension, or failure-to-appear information under the applicable compact rules; reporting and treatment on a driver's home-state record are governed by the participating jurisdictions' laws and compact procedures.
