Legal Limit

A legal limit is the maximum level of a substance or activity allowed by law. For example, in driving, it refers to the highest blood alcohol concentration (BAC) permitted while operating a vehicle, often set at 0.08% in many regions. These limits are established to protect public safety by controlling substances like alcohol, drugs, or pollutants, and they vary depending on the jurisdiction and context. Crossing a legal limit typically results in legal consequences, such as fines or penalties, because it indicates a risk to safety or compliance with regulations.
