Hazelwood, Missouri, in St. Louis County, has about 25,000 residents (2024 Census Bureau estimate). A DWI arrest in Hazelwood starts two cases, a criminal case in the St. Louis County Circuit Court and a license case before the Department of Revenue, and leaves three records. This guide follows the arrest from the roadside to the court file and the driving record.
This guide covers the law, the arrest, booking, the court case, the license case, the records and common questions.

The DWI Law in Missouri
Drunk driving is charged as DWI in Missouri, at a blood alcohol level of 0.08 or more.
Driving in Missouri is consent to a breath or blood test when an officer has cause to suspect DWI; the license case that follows a refusal or a failed test is run by the Department of Revenue, separately from the criminal case.
Who Makes DWI Arrests in Hazelwood
The agency that reports for Eureka makes the DWI arrests in and around Hazelwood.
The FBI's agency list also places two other agencies and three campus police departments in St. Louis County (the arrest records guide names each one).
Eureka reported 332 arrests to the FBI for 2025, all offenses together; the FBI's count for St. Louis County does not break DWI out.
The Pacific Police Department is listed by the FBI across two counties including St. Louis County, so its arrests are not broken out for St. Louis County here.

The License Case
The court case is only half the record. The Department of Revenue runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the Missouri Department of Revenue Driver License Bureau keeps the driving record the conviction goes on.
The Records a DWI Leaves
- The arrest report: from the agency that made the arrest, under the Missouri Sunshine Law.
