Numbers to know

3 questions from the Wyoming practice test

1. 1. What happens when a Wyoming driver's BAC is 0.08 percent or more after the required test?

   1. The license is suspended for 30 days
   2. The license and driving privileges are suspended for 90 days
   3. Only the vehicle registration is suspended
   4. There is no license consequence unless property is damaged
   Show answer

   The license and driving privileges are suspended for 90 days. The manual says a BAC of 0.08 percent or more brings a 90-day suspension of the driver license and driving privileges, along with possible criminal penalties. Thirty days is not the period given in this passage. Vehicle registration and property damage are unrelated to the stated alcohol-testing consequence. Remember that the administrative suspension described here follows the test result, while a criminal case can also expose the driver to separate penalties.

2. 2. A Wyoming driver is convicted of a second DWUI within 10 years. How long is the license suspension?

   1. Suspended for 90 days
   2. Suspended for one year
   3. Suspended for six months
   4. Suspended for three years
   Show answer

   Suspended for one year. A second DWUI within the previous 10 years brings a one-year suspension. If the driver also served an Administrative Per Se suspension, an additional nine-month suspension is added to the record. Under Wyoming law, limited driving privileges cannot be issued for any DWUI after the first offense unless the conviction includes alcohol, in which case a one year ignition interlock license is required. Ninety days is the first offense suspension, and three years is the revocation for a third or later offense.

3. 3. At what alcohol concentration is a Wyoming driver under 21 suspended under the Youthful Driver rule?

   1. 0.02 percent or more
   2. 0.05 percent
   3. 0.08 percent
   4. Any trace, even 0.001 percent
   Show answer

   0.02 percent or more. Wyoming's Youthful Driver Suspension applies to anyone younger than 21 in actual physical control of a vehicle with an alcohol concentration of 0.02 percent or more. The first offense suspension is 90 days. The 0.08 percent figure is the adult per se level, and 0.05 percent is the level at which an adult can be convicted with other supporting evidence. The rule sets 0.02 percent, not any trace amount.
