As few as ______ alcoholic drinks may cause a person to become legally intoxicated.

The effects of alcohol on a person depend on such factors as the person's weight. A person weighing less than 160 pounds will probably become legally intoxicated from consuming just two alcoholic drinks – and subject to arrest if he or she drives a motor vehicle. Four drinks will cause someone weighing as much as 240 pounds to become legally intoxicated. [Effects of Alcohol, Drinking and Driving, Be In Shape to Drive, New Mexico Driver Manual]
