1. What is Utah's legal blood alcohol content (BAC) limit for a driver 21 or older?
Why: Utah's per se BAC limit is 0.05% for drivers 21 and older (0.04% for CDL holders) -- the lowest standard-license threshold in the country, compared to the 0.08% used almost everywhere else.
2. Under Utah's Not-a-Drop Act, what BAC threshold applies to a driver under 21, and what happens on a first offense?
Why: Utah's Not-a-Drop Act denies all driving privileges for 6 months to a driver under 21 with any measurable amount of alcohol in their body, rising to 2 years (or until age 21) on a second offense within 10 years.
3. How long is a Utah driver's license suspended after a first DUI conviction for a driver 21 or older?
Why: A first DUI conviction results in a 120-day license suspension for a driver 21 or older, with a second or subsequent conviction resulting in a 2-year suspension.
4. What happens to your Utah driver license if you refuse a chemical test for the first time under the state's implied consent law?
Why: A first refusal under Utah's implied consent law leads to an 18-month license revocation (24 months if the driver is under 21), and a second or subsequent refusal leads to 36 months.
5. How long must a driver 21 or older keep an ignition interlock device (IID) installed after a first DUI conviction in Utah?
Why: A first DUI conviction restricts a driver 21 or older to a vehicle with an ignition interlock device installed for 18 months (36 months if the driver was under 21 at arrest); a second or subsequent DUI extends this to 2 years.
