Roads are often used by pedestrians and animals as well as by vehicles. Heavy alcohol consumption is frequently a contributing factor in accidents. Polish laws provide virtually zero tolerance for driving under the influence of alcohol.

Polish law prohibits Polish citizens from serving in the armed forces of a foreign state, and violators are subject to arrest and prosecution.
