Rules Regarding a Breathalyzer

Posted by Scott Markowitz | Jul 08, 2025 | 0 Comments

❓“Can I refuse a breathalyzer in Texas?”

  • Texas has an implied consent law. This means that by driving on public roads, you automatically agree to submit to a breath, blood, or urine test if an officer has probable cause to believe you are intoxicated.

  • While you can refuse, doing so triggers an automatic driver's license suspension, even if you are not ultimately convicted of a DWI.

  • For a first refusal, the suspension is typically 180 days. Subsequent refusals can lead to longer suspensions. 

  • Refusing a breathalyzer can be used as evidence against you in court. Prosecutors can argue that your refusal indicates consciousness of guilt, making your defense more challenging.

  • Some areas in Texas have "no refusal" policies, especially on weekends, holidays, or during special events. In these areas, officers can obtain a warrant to draw your blood if you refuse a breathalyzer test. 

Always ask to speak to your attorney first.🧾
