The DWUI Law in Wyoming
In Wyoming the offense is DWUI, and the limit is 0.08.
Driving in Wyoming is consent to a breath or blood test when an officer has cause to suspect DWUI; the license case that follows a refusal or a failed test is run by the Department of Transportation, separately from the criminal case.
For charging and sentencing, Wyoming counts prior offenses within 10 years.
Who Makes DWUI Arrests in Riverton
The Fremont County Sheriff's Office and the agency that reports for Riverton (filed by the FBI as Riverton Police Department) make the DWUI arrests in and around Riverton.
Together, the two agencies in Fremont County with all twelve months of 2025 on file reported 1,283 arrests to the FBI that year, all offenses together; the FBI's count for Fremont County does not break DWUI out.
