What’s All the Buzz About Drinking & Driving?

The legal limit when driving is currently 0.08% BAC in most states, although impairment in driving begins when you deviate from 0.00% BAC (blood alcohol content) at all. 

  • At 0.02% BAC, drivers have impairment of at least one driving skill. 
  • At 0.08% BAC, drivers have significant driving skill impairment.

Blood Alcohol Content
Driving skill impairment includes:

  • slower reaction time, 
  • decreased ability to keep an automobile in a steady position with traffic lane dividers, 
  • poorer concentration, 
  • decreased ability to divide their attention across multiple tasks, 
  • slower information processing, and 
  • decreased visual function.

The CDC provides these tips:

  • Designate a nondrinking driver before any party or celebration begins. Remind others to do the same.
  • Don’t drink and drive. Get a ride home from a sober friend or get a taxi or ride service.
  • Take the keys. Don’t let someone else drink and drive.
  • If you’re hosting a party where alcohol will be served, remind your guests to plan ahead and designate their sober driver, offer alcohol-free beverages, and make sure all guests leave with a sober driver.
  • Buckle up every time. It’s your best defense against a drunk driver.
