One of the worst aspects about drinking and driving accidents is that they are completely preventable. When people take the step to consume alcohol before getting behind the wheel, they are making a purposeful choice. Pennsylvania law is clear that any driver with a blood alcohol concentration beyond 0.08 is considered legally impaired and not permitted to drive.
One of the problems with the so-called "legal limit" for alcohol is that sometimes it can become difficult for bar owners, restaurant staff or other individuals who serve alcoholic beverages to know when a patron is beyond the legal BAC. The reason why that is important is because Pennsylvania recognizes the Dram Shop Act. These laws make it illegal for bartenders, servers and other alcohol licensees to sell beverage alcohol to minors and to customers who are visibly intoxicated.
