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 Platte County
The Platte County Sheriff's Office and the agencies that report for Wheatland and Guernsey make the DWUI arrests in Platte County.
Guernsey reported 1,146 arrests to the FBI for 2023, all offenses together; the FBI's count for Platte County does not break DWUI out.
Booking After a DWUI Arrest in Platte County
A driver arrested for DWUI and kept in custody goes to the county jail, whichever agency made the arrest. The jail, run by the Platte County Sheriff's Office, held about 75 people on an average day in 2019 by the Vera Institute of Justice's count and has a jail page SearchSystems verified at plattecountywyoming.com/departments/Sheriff/PatrolDeputies, phone 307-322-2331. The Platte County inmate search guide covers the jail in full.
The Court Case
The County Attorney files the charge, and the case is heard in the Circuit Court.

Wyoming has no single public index of every trial court case; each court's records are looked up through that court.
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.
