The National Transportation Safety Board revealed a new initiative Tuesday to curb the number of drunk driving fatalities.

The idea is to lower the legal blood alcohol limit from 0.08 to 0.05 or lower.

Now, any reduction in drunk driving fatalities is welcome. But it's important to point out that only a small fraction of alcohol-related deaths involve drivers with blood alcohol concentration levels between 0.05 on 0.07.

In fact, only 5.6 percent of alcohol-related fatalities in 2009 involved drivers whose BAC was between 0.01 and 0.07, according to the U.S. Census Bureau. That number has fallen from 6.3 percent in 1990 and is well short of the 32 percent of fatal accidents caused by those with BAC levels of 0.08 or higher. It is not known the exact percentage of alcohol-related fatalities attributed to those with BAC levels of 0.05 and 0.07.

Oh yeah, and don't drink and drive.
