Wyoming driving lesson · Losing the Privilege to Drive
Under-21 drinking and ignition interlock
A 3-minute lesson from the Wyoming course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Drivers under 21 face a much lower alcohol limit than adults. After certain DWUIs, anyone may have to drive with an ignition interlock, a breath-testing device you pay for, before getting any other license.
Know the rule
If you're under 21 and in actual physical control of a vehicle with an alcohol concentration of 0.02 percent or more, you'll be suspended for DWUI.
You may be eligible for limited privileges if you haven't been issued a probationary license in the past five years and have no ignition interlock requirement.
A device installed at your own expense after certain DWUI convictions. You must hold an interlock-restricted (IIR) license for the full period before any other license.
You can't get the IIR license if your privilege is suspended, revoked or canceled anywhere for any reason other than the DWUI that caused the interlock requirement.
You're 19 and stopped with a BAC of 0.03. That's over the 0.02 limit for drivers under 21, so you get a first Youthful Driver Suspension of 90 days.
Check your understanding
Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.
A driver's BAC at arrest was 0.15 percent on a first DWUI. What additional requirement applies?
A one-year ignition interlock restricted license
No additional requirement beyond the 90-day suspension
A six-month ignition interlock restricted license
A lifetime ignition interlock requirement
Answer: A six-month ignition interlock restricted license
If BAC at arrest was 0.15 percent or greater, the driver must hold an ignition interlock restricted license for six months before any other license type.
What ignition interlock requirement follows a fourth or subsequent DWUI conviction that involves alcohol?
10 years, with no petition option
For life, with no possibility of petition
Two years, with automatic removal after
For life, with a petition option after 5 years
Answer: For life, with a petition option after 5 years
A 4th or subsequent alcohol-related DWUI requires a lifetime ignition interlock requirement, but the driver may petition the court for removal 5 years after conviction.
