Sweden, Norway, Japan, and Poland are the countries with the lowest level of BAC, i.e., 0.03%. Furthermore, Saudi Arabia, the United Arab Emirates, the Czech Republic, Hungary, and Slovakia are countries that do not tolerate the BAC, and these countries are referred to as zero-tolerance countries against the BAC.

Why BAC Legal Limits Differ by Country
BAC limits are influenced by road safety policies, cultural attitudes toward alcohol, and accident prevention strategies. Countries with lower limits often adopt stricter rules to reduce alcohol-related fatalities. Some regions also apply different limits for novice drivers, professional drivers, or drivers under a certain age.
Because enforcement methods and penalties vary widely, drivers should never assume that laws in one country apply elsewhere.
BAC Limits and Driving Safety
Even when BAC levels are below legal limits, alcohol can still impair reaction time and judgment. Legal limits define enforceable thresholds, not safe drinking levels. The safest option is always to avoid driving after drinking any amount of alcohol.
