Cedar Park, Texas, in Williamson County, has about 78,000 residents (2024 Census Bureau estimate). A DWI arrest in Cedar Park starts two cases, a criminal case (in the County Court at Law, or the District Court when it is charged as a felony) and a license case before the Department of Public Safety, 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 Texas
Drunk driving is charged as DWI in Texas, at a blood alcohol level of 0.08 or more.
Driving in Texas 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 Public Safety, separately from the criminal case.
Texas sets no time limit on prior offenses: every earlier conviction counts toward a repeat charge.
Who Makes DWI Arrests in Cedar Park
The Williamson County Sheriff's Office and the agency that reports for Cedar Park (filed by the FBI as Cedar Park Police Department) make the DWI arrests in and around Cedar Park.
The FBI's agency list also places eight other agencies and one campus police department in Williamson County (the arrest records guide names each one).
Together, the 12 agencies in Williamson County with all twelve months of 2025 on file reported 6,720 arrests to the FBI that year, all offenses together; the FBI's count for Williamson County does not break DWI out.
The Thorndale Police Department, the Pflugerville Police Department and the Austin Police Department are each listed by the FBI across several counties including Williamson County, so their arrests are not broken out for Williamson County here.
Booking After a DWI Arrest in Cedar Park
A driver arrested for DWI and kept in custody goes to the county jail, whichever agency made the arrest.

The Cedar Park inmate search guide covers the jail in full.
The Court Case
A DWI charge from Cedar Park is brought by the District Attorney in the County Court at Law, or the District Court when it is charged as a felony.
The District Attorney's page SearchSystems verified is at wilcotx.gov/256/District-Attorney, phone 512-943-1234.
The court records page SearchSystems verified for the county is at wilcotx.gov/257/Court-Case. That page belongs to a lower court, the County Courts and Justice Courts, not to the Williamson County District Court.
Texas has no single public index of every trial court case; each court's records are looked up through that court.
The License Case
A DWI arrest starts two cases: the criminal one above and an administrative one over the license, run by the Department of Public Safety. The driving record, kept by the Texas Department of Public Safety, carries the result of both.
The Records a DWI Leaves
- The arrest report: from the agency that made the arrest, under the Texas Public Information Act.
- The court file: from the County Court at Law, or the District Court when it is charged as a felony, kept by the District Clerk for district court cases and the County Clerk for county court cases.
- The driving record: from the Texas Department of Public Safety.
