How much does an interlock cost in Colorado?

Posted by Neil Shouse | Jan 19, 2020 | 0 Comments

Ignition interlock device (IID) installation typically costs from $70 to $200. And monthly maintenance ranges from $60 to $90.

1. Do DUI defendants purchase IIDs?

No. In Colorado, DUI defendants typically lease IIDs. And defendants are responsible for bringing them into IID vendors for regular calibrations.

2. Is there financial assistance available?

Yes. To qualify, defendants must meet the following five criteria:

  1. Be a first-time offender or designated as a persistent drunk driver;
  2. U.S. citizenship;
  3. Colorado residency;
  4. Be over 21 at the time of the DUI; and
  5. Show state tax returns that demonstrate an income close to poverty guidelines.

3. Does everyone convicted of DUI need to get an IID?

Only if the defendant wants to get a IID-restricted driver's license. Defendants who choose not to drive during their license suspension period do not need an IID.

DUI defendants typically have to wait one or two months before they may be eligible for a restricted license.

4. How long do I need to have an IID?

It depends on the specific Colorado DUI charge. People convicted of a DUI-1st get a nine-month license suspension. But they may resume driving after only one month with an IID. And if they drive for four months straight without incident, they may be able to get the IID removed early.

5. What happens if I tamper with the IID?

The DMV may revoke the defendant's restricted driver's license. This means the defendant will be unable to drive at all during the suspension period.

In addition, the defendant may be charged with a class 1 misdemeanor. The penalties for violating 42-2-132.5 C.R.S. include:

  • 6 months in jail, and
  • $500 in fines

"Tampering" with an IID comprises such actions as:

  • Removing the device from the vehicle;
  • Rewiring the device so it does not prevent the car from running;
  • Using another person's breath sample;
  • Helping a DUI defendant to avoid using the device

Most IIDs have cameras and log every breath sample. And this information can come in as evidence against tampering suspects.

6. How do IIDs work?

IIDs are small breathalyzer devices attached to a car's steering wheel. They prevent a car from starting if they detect alcohol in the driver's breath.

IIDs continue to demand random breath samples while the car is in motion. Drivers usually have four to six minutes to provide the sample. If it detects alcohol, it will instruct the driver to pull over and turn off the vehicle. In some cases, the car's lights will flash and the horn will sound until the vehicle turns off.

7. Where can I get an IID?

Approved providers in Colorado include:
