The legal alcohol limit for drivers in England, Wales, and Northern Ireland is 80 mg of alcohol per 100 ml of blood. This standard has been established to mitigate the risks associated with drinking and driving, as alcohol impairs reaction time, judgment, and coordination, significantly increasing the likelihood of accidents.

Setting the limit at 80 mg is a balance between allowing for moderate drinking and ensuring road safety. It serves as a clear guideline for both law enforcement and drivers. Exceeding this limit can lead to serious legal consequences, including hefty fines, penalty points on a driving license, or even disqualification from driving.

The options that propose lower or higher limits are not applicable in this context, as the legal limit set by law is established at 80 mg. Understanding this limit is crucial for all drivers to make informed decisions about their alcohol consumption and driving responsibilities.
