Penalty snapshot
DUI and DWI offences are criminal and vary by state.
Adult BAC limits alone are not enough. Many jurisdictions apply stricter thresholds to drivers who are new, professional, or below the legal drinking age.
Novice drivers
Many countries cut the limit for new drivers well below the main adult limit to reduce early crash risk.

These answers help frame the table correctly: legal thresholds are enforcement lines, not safety guarantees.
A BAC of 0.05% means about 0.05 grams of alcohol per 100 milliliters of blood, while 0.08% means 0.08 grams. Research cited in road-safety guidance shows that reaction time and judgment are already measurably impaired at 0.05%.
Yes. The United States, Canada, Australia, and the United Kingdom all show internal variation. One province, state, or constituent nation may apply a stricter rule than another even when the country is usually described with one headline BAC number.
Yes. Visitors are fully subject to local drink-driving law. Not knowing the local threshold is not a defence, especially when renting a car or driving across borders.
Common methods include roadside breath testing, blood testing, and sometimes urine testing. Breath tests are the most common roadside tool, while blood testing is usually treated as the most precise direct measurement.
In many jurisdictions, refusing a test is its own offence and can carry penalties equal to or worse than failing the test. The exact consequences depend on the local law and the type of driver licence involved.

Reference set and maintenance
This page is intentionally source-forward. Each country row includes the supplied reference numbers, and the project brief calls out WHO-era public data, IARD, and open web summaries as the base set.
This page is for reference only and is not legal advice. National, provincial, and state rules can change at any time, and local enforcement can vary even when a headline BAC number looks familiar. Check with the local authority or your rental-car provider before driving. Regardless of the legal limit, zero alcohol is the safest choice if you plan to drive.
