Drunk driving remains one of the most pressing public safety concerns globally. While the fundamental principle—prohibiting driving under the influence of alcohol—remains consistent, the specific laws, penalties, and enforcement methods differ from country to country. Understanding these variations is essential for anyone traveling or residing in these regions. This article delves into the drunk driving laws of the United States, United Kingdom, Canada, Germany, and Mexico, providing a detailed comparison of legal limits, penalties, and enforcement practices.

Driving under the influence (DUI) or driving while intoxicated (DWI) is primarily regulated at the state level, leading to variations in penalties. However, common consequences include:
- First Offense:
- Fine: $500–$2,000
