Missouri DWI Laws

Navigating DWI laws and the ignition interlock device (IID) process in Missouri can be confusing. If you’re unsure whether you need an IID, how long the program lasts, or the specific requirements for installation and calibration, you’ve come to the right place. LifeSafer can answer all your questions about Missouri IID laws, including:

  • Who needs an IID in Missouri? (e.g., first-time DWI offenders, subsequent DWI offenses)
  • How long do I need an IID in Missouri? (varies based on offense severity)
  • What are the IID calibration requirements in Missouri? (regular calibrations to ensure accuracy)
  • What happens if I fail an IID test in Missouri? (potential program extension or license suspension)
  • What are the Missouri DWI interlock laws for programs after a DUI with injury? (may have stricter requirements)

We understand that getting back on the road legally and safely is your priority. LifeSafer’s Missouri IID program ensures compliance with all state regulations, helping you regain your driving privileges with confidence. Read further to learn the specifics of Missouri IID laws.

Administrative: This happens if you fail a breath test, or refuse to take one. You have 15 days from the date of arrest to file a written request for an administrative hearing. If you do not request a hearing, or if it is unsuccessful, you must begin a suspension period which varies according to your prior record of offenses.

Judicial: This occurs when you are sentenced by a court after a trial or plea agreement. You must deal with both suspensions in order to regain your driving privileges. You may also face fines,  jail time or other requirements.

Missouri offers DWI Courts as an alternative for a DWI offense. These courts focus on treatment and prevention of further alcohol-related legal problems. More information can be found here.
