The National Transportation Safety Board recently recommended that states lower their DWI thresholds from .08 percent to .05 percent.
The NTSB is an independent federal agency that does not have the ability to make regulations but makes recommendations to state and federal agencies that often become regulations. For example, the NTSB's prior recommendation to lower the drunk driving limit to .08 from .10 was adopted by states, as was its recommendation to raise the drinking age to 21.
