CINCINNATI - There's a new push to lower the blood alcohol standard used to determine if a driver is drunk.
Many times determining when someone has had too much to drink can be hard to measure.
"Obviously the curve starts at 0 and at about 0.08 it starts to sharply rise up," said Dr. E. Don Nelson, who has worked in toxicology for the past 40 years.

Nelson says there is no real science to back up the effort to lower the legal drinking standard.
"We have federal regulations that say you can land an airplane in instrument conditions at 0.04, and to say, if you have half a more beer in your body, you're unable to drive safely. I don't think makes common sense and I don't think it makes scientific sense."
The National Transportation Safety Board (NTSB) says more than 100 countries have adopted .05 alcohol content standard. In those countries drunk driving deaths were reduced by half within 10 years.
"Frankly, the crime of DUI is a cash cow for government," said DUI defense attorney Steve Adams.
Adams disputes figures from the NTSB which say more than a third of the 30,000 Americans killed in car crashes are alcohol related.
"And basically what the government would do if they reduce it to a .05 is criminalize perfectly legal and acceptable behavior," said Adams.
"You can argue that .08 supported by good science, I don't think you can argue that someone who is at .05 unable to operate a motor vehicle safely," he added.
Currently the legal limit for driver on Tri-State roads is .08, but federal accident investigators would like to see the legal limit lowered to .05, almost half the current level.
