Wyoming Ignition Interlock DUI Laws

Your driver’s license will be administratively suspended for 90 days if you are arrested for impaired driving.  The arresting officer will issue a temporary 30-day license at the time of arrest, but you must follow the instructions to obtain a probationary license to continue driving.  You must complete an alcohol assessment before applying for a probationary license.  A probationary license will not be issued if you have an interlock requirement.

Wyoming ignition interlock laws require that an ignition interlock device (IID) be installed on all vehicles for anyone convicted of a DUI with a blood alcohol concentration (BAC) level of .15 or greater, as well as second and subsequent DUI offenses regardless of the driver’s BAC. Depending on the driver’s record, the interlock must be installed for a period of 6 months to one’s entire lifetime.

If you are convicted of operating under the influence of intoxicating liquor, first offense, it is considered a misdemeanor punishable by imprisonment for not more than six (6) months, a fine of not more than seven hundred fifty dollars ($750.00), or both.  For second and subsequent convictions, the penalties increase.

Wyoming also offers deferred prosecution for impaired driving cases, in which case an interlock must be installed. You can purchase an interlock device here.

Wyoming offers Court Supervised Treatment Programs (also known as DUI Courts) for qualifying offenders in certain locations.  For more information, click here.
