Willis, Texas, in Montgomery County, has about 7,200 residents (2024 Census Bureau estimate). A DWI arrest in Willis 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 Willis
The Montgomery County Sheriff's Office and the agency that reports for Willis (filed by the FBI as Willis Police Department) make the DWI arrests in and around Willis.
The FBI's agency list also places eight other agencies in Montgomery County (the arrest records guide names each one).
Together, the 11 agencies in Montgomery County with all twelve months of 2025 on file reported 11,055 arrests to the FBI that year, all offenses together; the FBI's count for Montgomery County does not break DWI out.
The Cleveland Police Department and the Houston Police Department are each listed by the FBI across several counties including Montgomery County, so their arrests are not broken out for Montgomery County here.
Booking After a DWI Arrest in Willis
A driver arrested for DWI and kept in custody goes to the county jail, whichever agency made the arrest. The jail, run by the Montgomery County Sheriff's Office, held about 1,110 people on an average day so far in 2026 by the Vera Institute of Justice's count and has a custody page SearchSystems verified at mcsojail.countygovservices.com/Home/CurrentInmates. The Willis inmate search guide covers the jail in full.
The Court Case
A DWI charge from Willis 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 mctxdao.org, phone (936)539-7800.
The court records page SearchSystems verified for the county is at mctx.org/departments/departments_d_-_f/district_clerk/case_inquiry.php, phone 936-539-7855.
Texas 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 Public Safety runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the Texas Department of Public Safety 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 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.
