 The effects of drinking can be subtle. When your blood alcohol level hits .02, you feel good, relaxed. At .05, you may have a little trouble tracking objects. And at .08, you'll be slightly less alert. You might not even notice it. But a breathalyzer will. If you're driving over the limit, you will be arrested, even if you don't feel drunk. So don't chance it. Always use a designated driver. Brought to you by the South Dakota Office of Highway Safety, South Dakota Broadcasters Association, and this station.
