Hello,\rThe amount of time that your driver's license will be restricted following a DUI depends on a couple of different circumstances. Drivers who are 21 or older and show a blood alcohol content (BAC) level of 0.08% or more will have their license suspended for four months if it is their first offense. If it is your second offense in 10 years, it will be restricted for a year. \r\rDrivers who are under the age of 21 and show a BAC of 0.01% can plan to face a one-year suspension following a first-time offense. \r\rThe laws change slightly for drivers who refuse to undergo a blood or breath test. \rRegardless of age, drivers who refuse to submit to a blood or breath test during a DUI traffic stop will have their license restricted for a year following a first-time offense. A second offense in 10 years will result in having your license revoked for two years, and a third offense in 10 years will result in having your license revoked for three years.
