The DWUI Law in Wyoming
Drunk driving is charged as DWUI in Wyoming, at a blood alcohol level of 0.08 or more.
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 Niobrara County
The Niobrara County Sheriff's Office and the agency that reports for Lusk make the DWUI arrests in Niobrara County.
Lusk reported 40 arrests to the FBI for 2025, all offenses together; the FBI's count for Niobrara County does not break DWUI out.

The License Case
The court case is only half the record. The Department of Transportation runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the Wyoming Department of Transportation keeps the driving record the conviction goes on.
The Records a DWUI Leaves
- The arrest report: from the agency that made the arrest, under the Wyoming Public Records Act.
- The court file: from the Circuit Court, kept by the Clerk of District Court.
- The driving record: from the Wyoming Department of Transportation.
