Safe Driving
¹The major threat to the lives of college students isn't illness but injury. Almost 75 percent of deaths among Americans 15 to 24 years old are caused by "unintentional injuries" (a term public health officials prefer) , suicides, and homicides. Accidents, especially motor vehicle crashes, kill more college-age men and women than all other causes combined; the greatest number of lives lost to accidents is among those 25 years of age. One key factor in increasing your odds of staying safe on the road is staying sober and alert.
²The number of fatalities caused by drunk driving, particularly among young people, has dropped. The National Highway Traffic Safety Administration attributes this decline to increases in the drinking age, to educational programs aimed at reducing nighttime driving by teens, to the formation of Students Against Destructive Decisions (SADD, originally called Students Against Drunk Driving) and similar groups, and to changes in state laws that lowered the legal blood-alcohol concentration level for drivers under age 21 (some states have zero tolerance blood-alcohol level for drivers under 21) . Although most drunk drivers are men, more young women are driving drunk and getting into fatal car accidents than ever before. More young women than men involved in deadly crashes had high blood-alcohol levels in a recent analysis of data from the National Highway Traffic Safety Administration.
³Falling asleep at the wheel is second only to alcohol as a cause of serious motor vehicle accidents. About half of drivers in the United States drive while drowsy. Nearly 14 million have fallen asleep at the wheel in the past year, according to the National Sleep Foundation. Men and young adults between the ages of 18 and 29 are at the highest risk for driving while drowsy or falling asleep at the wheel. In a recent study, adolescents who had at least one previous crash reported more nighttime driving, more occasions of driving while sleepy, bad sleep, and use of stimulants such as caffeinated soft drinks, tobacco, and drugs.
