DUI Defense in Wyoming

 That Starts With the Evidence


Arrested for DUI?

Here’s What Happens Next

A DUI arrest can feel immediate and overwhelming, especially when you’re unsure how court proceedings and license issues connect. In Wyoming, you may be dealing with both criminal charges and a WYDOT license action at the same time, each with its own deadlines and consequences. Matzen Brandon LLC approaches DUI defense with a focus on chemical testing, procedure, and trial readiness so your case is built on more than assumptions. Whether you're in Cheyenne, Gillette, Rawlins, or Laramie, you get clear direction on what to do next and how to protect your license and record.

Situations We Handle in DUI Cases Every Day

First Offense DUI

If this is your first DUI, you may be unsure how serious the consequences are or what steps to take. You get clear guidance on penalties, options, and how to approach your case from the beginning.

Breath Test Issues

If your case involves a breath test, accuracy and calibration can become central issues. Your defense includes reviewing how the test was administered and whether procedures were followed correctly.

Blood Test DUI Cases

Blood testing introduces additional steps, including collection, storage, and lab analysis. You receive focused review of how samples were handled and whether results are reliable.

Refusal Cases

Refusing a test can lead to separate administrative consequences. Your strategy addresses both the refusal and how it impacts your overall case.

Out-of-State Drivers

If you were arrested while traveling through Wyoming, you may be dealing with court obligations from a distance. You get guidance on how to manage your case while minimizing disruption to your life.


Mistakes That Can Make a DUI Case Harder to Defend

Waiting Too Long to Act

Deadlines for license actions can pass quickly, limiting your options before your case even begins.

Assuming Test Results Are Final

Breath and blood test results are often treated as conclusive, but procedures and accuracy can be challenged.

Talking Without a Strategy

Statements made early can affect your case later; having a plan before responding matters.

Missing the Administrative Side

Focusing only on court while ignoring license consequences can create additional problems.
