2. You refuse the blood, breath or urine test an officer directs. What is the consequence for a first refusal?
Correct answer: Loss of the privilege to drive for one year

3. Under Nevada's illegal per se rule, what alcohol concentration revokes a driver's privilege?

4. What device can allow a DUI offender's driving privileges to be restored right away?
Correct answer: An ignition interlock installed at the driver's own cost
Fitting an interlock to every vehicle the person drives, and holding a license carrying that restriction, lets the privilege come back immediately at the offender's expense.

8. A commercial license holder is tested. Which reading already triggers administrative action?
Correct answer: .04% or more but under .08%

10. How does having a 12-year-old in the car affect a Nevada DUI sentence?
Correct answer: The court treats it as a factor that makes the offense worse

11. A 19-year-old Nevada driver tests at .03% alcohol concentration. What happens?
Correct answer: The driving privilege is suspended, because under-21 drivers face action at .02%
For drivers below twenty-one, a reading of two hundredths of a percent up to but not reaching the adult limit triggers administrative suspension, and an officer may take the license on the spot.

12. How long is the license revoked for a second DUI conviction within seven years?
Correct answer: One year
