In
2013, the National Transportation Safety Board (NTSB) proposed
lowering the blood alcohol content to 0.05 to cut down the risk of
DWI accidents. Mothers Against Drunk Driving (MADD), the minds behind
DWI
law
in the U.S., welcomes the development. The recommended BAC, however,
still remains at 0.08.
The
BAC limit used to be much higher. Back then people hadn't heard much
of the dangers and consequences of "driving under the
influence." Only a few studies delved into the cognitive effects
of alcohol. Indiana took the lead by imposing a 0.15 presumptive
limit in 1939; 16 years later, Minnesota followed.
