If you're worried you've had too many drinks to get behind the wheel on New Year's Eve, fear not: There's an app for that.
Just reach for your iPhone, because several apps are now available to tell someone when they've reached their legal limit.
"R-U-Buzzed," a free application released Dec. 2 from the
Colorado Department of Transportation, allows you to quickly determine your blood alcohol level. Simply spin the wheel to your weight, how many drinks you've had and the amount of time you've been drinking and the app will tell you if you're safe to drive.
