Do you know your limit when it comes to drinking? Did you know that even one or two drinks can impair your ability to drive? Always plan for a safe ride home BEFORE you start drinking. 

R-U- Buzzed estimates your blood alcohol concentration (BAC) level based on the interaction of weight, gender, time you’ve been drinking and alcohol consumed. For this calculator, one drink is considered to be equal to 12 oz. of beer, 5 oz. of wine or 1.5 oz. of hard liquor. 

Use the “Need a Ride?” button to connect to popular ride-hailing services, including Uber, Lyft, zTrip and Curb.


Disclaimer: This blood alcohol concentration (BAC) calculator is only an estimate and is not sufficiently accurate to be considered legal evidence. The calculations are averages, and many variables could affect an individual’s BAC level.

Food in the stomach, medications, health and psychological conditions are influencing factors and many establishments serve alcohol in portions larger than the standard drink size. Do not use the R-U- Buzzed app to determine whether you should operate a motor vehicle or other heavy equipment. It is never safe to drive after any amount of alcohol. You can be arrested for impaired driving if your driving ability is affected to even the slightest degree.

R-U- Buzzed is provided by the Colorado Department of Transportation (CDOT).
