Red BAC's: It is illegal to drive with a BAC of .08% or higher (if you are under 21 it is illegal to drive with a BAC of .02% or higher)
Purple BAC's: At risk of an overdose (alcohol poisoning)

Remember:
This chart, like all BAC charts, serves as a guideline. Everybody responds differently to alcohol and alcohol absorption rates can vary due to many factors. BAC charts do not take into account food consumption, stress levels, fatigue levels, medication and other drug interactions, etc. Additionally, your body processes alcohol at the rate of .05 ounces per hour, thus if you maintain the same number of drinks per hour, you will actually raise your BAC. For example, a 160 pound male consuming 3 drinks per hour for 2 hours will have an estimated BAC of .095.
