2010-11 DUI Law Changes
Colorado modified the amount of time an offender is required to stay in jail for a DUI conviction and now imposes a 10-day minimum jail term for a second offense as well as a 60-day minimum jail sentence for a third and subsequent offenses. Additionally, the law has eliminated the requirement that an offender wear an ankle bracelet leaving only two options: either serve requisite time or apply for a work release program.

Drinking and Driving Laws in Colorado
Drunk driving laws in The State of Colorado are similar to other DUI laws in the United States, however Colorado also has a Driving While Ability Impaired (DWAI) law that makes it illegal to drive with a lower blood alcohol concentration (BAC) level that is lower than most states. The DWAI law starts at 0.05 percent (BAC) whereas most states start with a 0.8 percent BAC. The Colorado DUI law prohibits a person from driving when they have a concentration of .08 percent or more alcohol in their blood system. This is the standard measurement use by most states for the "impaired" driver.
The first time you are caught driving with a blood alcohol content of .08 or above, you are guilty of driving under the influence. The fine for your first DUI is from $300- $1000. You will spend between 5 days to 1 year in jail with mandatory public service from 48 to 96 hours. You will also have your license revoked for 1 year.

How many drinks does it take to reach the legal limit in Colorado?
There are many variables that determine if a person has reached the legal limit, however what may make one person legally drunk, isn't always the case with another individual. There are BAC calculators and Alcohol Charts that can serve as a point of reference, but again individual factors such as age, weight and the duration of time that has passed between drinks all play into the equation. There isn't a single formula that works for everyone. On average it takes very little alcohol to become legally drunk and the best answer to drinking and driving is to have zero drinks before you drive.
