A legal limit is not a safe dose
Alcohol can affect driving below the statutory threshold. A calculator cannot decide whether a person is fit to drive.
Law and safety
Drink-driving limits around the world
Compare the general BAC threshold with lower limits for novice, young and professional drivers. Comparison values use the unit of the selected legal system, while each country’s local notation remains visible.
One country can have several limits
Lower rules often apply to learners, young or professional drivers, passenger transport and particular vehicle classes.
Zero tolerance means zero
Instrument tolerances and higher criminal thresholds are not an extra permitted allowance for drinking and driving.

General limit means the rule shown for an ordinary car driver. A lower threshold may apply sooner to a novice, professional or under-age driver.
Impairment rule without a BAC number means the law prohibits impaired driving without giving one general numeric value. It is not permission to drive after drinking.
Alcohol prohibited or restricted describes jurisdictions with broader alcohol controls where the sources do not state a separate BAC threshold.
No confirmed number means the available evidence was not strong enough to publish a specific value.

A legal limit is not a safety limit. If you have been drinking, do not drive — use public transport, a taxi or a sober driver.
Methodology
General threshold first, then the exceptions
The database covers 198 countries and territories. The main value is the threshold for an ordinary car driver. Lower limits for novice, young or professional drivers and special vehicle categories are described separately.
The comparison source records BAC in mg/ml. For readability, we convert those values into the unit familiar from the selected country's legal system. Where no single confirmed value is available, we distinguish a law defined through impairment, a wider restriction involving alcohol, a threshold stated only for breath, and a genuine lack of sufficient data. We do not enter zero simply because a source did not provide a number. Last reviewed: 7 września 2026.
