Keep in mind that you burn off alcohol at approximately a .015% per hour.
So, a 190 pound man having 8 drinks in 4 hours would roughly have a BAC of 0.1%.
* Example: ((190lb man w/8 drinks in an hour (0.16%)) - (reduction over a 4 hr time span (0.15x4))) = 0.1% BAC, which is over the legal limit of 0.08% in Wisconsin.
The average male will eliminate about 2/3 of a drink per hour, while the average woman will eliminate about 1/2 of a drink per hour.
There are several factors that go into "intoxication, " such as tolerance or sensitivity, mixing with prescription medication, etc. So, you should not use these tables to determine anyone's fitness to drive. Purchasing a BAC meter, which are available at stores or online do not accurately detemine "fitness" to drive either. If you drink you should not drive; consider a designated driver or taxi cab instead!
