The National Transportation Safety Board recommends lowering the legal blood alcohol content from 0.08 to 0.05.
The proposal comes with a few others in a report from the NTSB. They also want al convicted DUI offenders to use breathalyzer ignition locks on their cars.
The NTSB admits lowering the legal blood alcohol content may seem counterintuitive when most of the fatal crashes across the nation are caused by people with BAC's well over 0.08.
But the NTSB says research shows lowering the BAC levels changes the drink-driving behavior of drivers at all BAC levels.
The NTSB says research also shows countries with a 0.05 legal limit have substantially fewer drunk-driving fatalities.
Duquesne Police Chief Tommy Kitch says his department already pulls over drivers who seem to be impaired and have charged them with a DWI regardless of their blood alcohol content.
"We've charged people who have less than a 0.08 with a DWI, we've also had convictions with a less than .08, sometimes there's other factors involved, which would include drugs, no sleep," says Chief Kitch.
According to the NTSB, alcohol begins to affect perception and visual functions at 0.05, and in 100 countries around the world, 0.05 is the standard.
