Recently the National Transportation Safety Board (NTSB) recommended that the legal limit for Blood Alcohol Concentration (BAC) that would constitute a criminal offense for Driving Under the Influence (DUI) be lowered from .08 to .05. Currently every state sets their legal limit at .08, including Pennsylvania, but it seems probable that most, if not all, states will eventually accept this recommendation based on past precedent. The last time the NTSB made a recommendation to lower the legal limit for DUI offense from .10 to .08, all states eventually accepted that recommendation with Pennsylvania enacting the .08 limit in 2003.
