Size and alcohol content of typical drinks
Can of beer: 12 oz./2%–12% ABV (usually 4%–6% ABV)
Glass of wine: 4 oz./9%–16% ABV (usually 12.5%–14.5% ABV)
One shot of hard alcohol: 1.5 oz./30%–50% ABV (usually 40% ABV)

What does this mean?
According to the law in Ohio, and most states, you're considered legally drunk if your Blood Alcohol Content (BAC) reaches .08 percent.

The National Transportation Safety Board recently recommended that all 50 states lower the threshold to 0.05 percent. » Read the full story

How quickly you reach that number depends on your weight, your tolerance for alcohol, how much you're drinking, and how long you've been drinking.

The legal blood-alcohol content limit should be lowered, officials with the National Transportation Safety Board said.

The NTSB voted today to recommend all 50 states lower the threshold to 0.05.

Currently the blood-alcohol content limit is 0.08. NTSB officials believe lowering the legal limit will reduce the nation’s drunken driving death toll, which according to CNN has plateaued at about 10,000 deaths annually.

According to CNN, under current law, a 180-pound male will hit the 0.08 threshold after four drinks in an hour. If it lowers to 0.05, that would occur after two to three drinks in an hour.

Blood-alcohol content levels are influenced by a person’s gender, weight and other factors.

The independent NTSB is influential on matters of public safety but only makes recommendations, not laws.
