Despite a federal safety board's recommendation that states lower their standards for blood-alcohol levels that qualify as drunk-driving, any changes to the thresholds will likely come slowly.
If history is any guide, the current .08 blood-alcohol limits in Pennsylvania and New Jersey could remain on the books for decades, though legislators in either state could introduce bills to lower the threshold at any time.
The National Transportation Safety Board called this week for states to lower the blood-alcohol content threshold for drunken driving to .05. The board last recommended a change in 1982, according to USA Today, when it urged states to lower their drunk-driving standards from .10 to .08.
The next year, Utah and Oregon became the first states to lower their limits.
It took more than two decades for the laws to change in some states, including Pennsylvania and New Jersey.
By the end of 2004, all 50 states had changed their laws.
Safety officials have acknowledged that the NTSB recommendation probably won't lead to quick changes.
"It was very difficult to get .08 in most states so lowering it again won't be popular," Jonathan Adkins, a spokesman for the Governors Highway Safety Association, told the Associated Press earlier this week. "The focus in the states is on high (blood alcohol content) offenders as well as repeat offenders. We expect industry will also be very vocal about keeping the limit at .08."
