Driving and drinking accounts for large numbers of motor vehicle accidents. In an effort to prevent this, most states have limit laws governing the level of alcohol which is allowed in the blood stream of a driver. In most states this level is:

A. 0.10% This was the legal limit in the past, but not currently in most states. B. 0.5% A level of 0.5% would likely result in coma or death. C. 0.08% This is the current legal limit in most U.S. states for blood alcohol concentration (BAC) when operating a motor vehicle. D. 0.12% Higher than the legal limit. A person with this BAC would be considered legally impaired.
