Drunk drivers are responsible for approximately one-third of all traffic crash fatalities in the U.S., according to the National Highway Traffic Safety Administration (NHTSA). In fact, nearly 10,500 people were killed in alcohol-related crashes in 2016 alone, and more than 10,000 people died each year during the previous decade.
A drunk driver is someone who has a blood alcohol concentration (BAC) of .08 or higher. This is the equivalent of approximately four alcoholic drinks. According to the U.S. Centers for Disease Control and Prevention (CDC), alcohol at that level can affect a variety of capabilities, including (but not limited to):
- Muscle coordination
- Information processing
- Self-control and judgment
- Speed control
