IGNITION INTERLOCK DEVICES (IID) AS MISSOURI DWI SANCTIONS

UNDERSTANDING THE USE OF IIDS IN DWI DEFENSE STRATEGY

A Missouri conviction for Driving Under the Influence (DUI) or Driving While Intoxicated (DWI) may result in the use of an Ignition Interlock Device (IID). Experienced attorneys at the Law Office of Kenneth P. Carp understand how the law uses Ignition Interlock Devices (IID). If you’re facing a DUI or DWI or an offense relating to an IID, contact our lawyers who are ready to aggressively defend you in Greater St. Louis.

Here are some of the main features of the Ignition Interlock Device:

  • Hand-held breath testing device
  • Connected to the vehicle’s ignition, horn and headlights
  • The driver must breathe into the IID without registering a blood alcohol concentration (BAC)
  • Vehicle will not start if test registers a BAC



Ignition Interlock Devices can be a resource which makes the difference between a driver being able to drive or not. An inability to drive can make the difference in putting the food on the table. Our attorneys know when the law requires an IID or when to suggest it as an option to getting you back on the road.

IIDs are life-changing and costly. Call us at 636-947-3600 for a free consultation with an experienced traffic attorney.

IID installation is closely regulated by the state:

  • Installers must be certified by Missouri Department of Transportation (MoDOT)
  • IID installer notifies Department of Revenue once installation is complete
  • IID installer notifies Department of Revenue of any IID failure
  • Installer notifies Department of Revenue if IID isn’t maintained
