If I am convicted of DUI how long do I have to have the Ignition Interlock?

by Aaron Black • February 20, 2012
Even if you have never had a DUI, if convicted of DUI, you will have to install the ignition interlock anywhere from 6 months to 18 months. 

1st Time DUI

  • If you have been convicted of first time DUI under a .15 the ignition interlock must be installed for 12 months. This can be reduced to 6 months.
  • A DUI conviction over a .15 and below a .20 requires the ignition interlock for a minimum of 12 months.
  • A Super Extreme DUI conviction, over a .20, requires the ignition interlock for 18 months.

2nd Time DUI Within 84 Months (after a 1 year license revocation)

  • DUI conviction under a .15 the ignition interlock must be installed for 12 month.
  • DUI conviction over a .15 and below a .20 requires the ignition interlock for a minimum of 12 months.
  • A Super Extreme DUI conviction, over a .20, requires the ignition interlock for a minimum of 2 years.

Early removal of the Ignition Interlock Device

As of right now, there is only one exception to get the ignition interlock removed early:
  1. Your DUI occurred on or after January 1, 2012, and
  2. Your conviction was for a first time non extreme DUI, and
  3. You successfully completed an alcohol or drug education course, and
  4. You had a functioning ignition interlock in your vehicle for 6 months, and
  5. You did not attempt to drive with a .08 BAC two or more times, and
  6. You did not have a damage or injury accident.
If you satisfy the above listed terms your ignition interlock could be removed after only six months of the one year requirement.
