When Did State DUI Laws befall Consistent?

States with impaired driving laws were strongly confident by the American Medical relationship and central agencies to set BAC levels at 0.15 percent or lower but they were free to begin their own strategy. States also had dissimilar drinking ages ranging from 18 to 21 but research showed that higher-ranking drinking ages connected with lower drunk heavy rates. This distorted in 2000 when Congress passed a law requiring each state to set its BAC limit at 0.08 percent and set up the drinking age at 21. Since the penalty for disobedience was the loss of millions of dollars in federal highway funds all states ultimately fell in line. In 2013, the National Transportation Safety Board suggested lowering BAC limits to 0.05 percent.
