Drink-driving is a major public health problem and, in the U.S. at least, is particularly prevalent among college students. A study by researchers at the University of Maryland reveals the extent of the problem and shows that it gets worse when students reach the U.S. legal drinking age of 21. The researchers studied 1,253 students who were asked annually whether they had got into a car with a drunk driver, had driven after drinking and had driven while drunk. At 20 43% said that they had got into a car with a drunk driver, 8% had driven after having a drink and 20% had driven while drunk themselves. There were notable increases in all three figures when the students reached 21.
