The installation cost of an IID may vary. It is advisable to contact approved Colorado IID vendors like Intoxalock or Guardian for a personalized quote tailored to your specific vehicle.

Yes, there are ongoing costs tied to IID usage. Since you rent the IID from the vendor, you will be required to pay a monthly fee. This fee typically covers regular calibrations, which occur monthly or bi-monthly. Monthly fees usually hover around $70, but exact costs may vary based on the chosen vendor.

The frequency of required breath tests with an IID depends on your driving situation. After starting the vehicle, your car will initially indicate the need for a rolling retest after approximately five minutes of driving. Subsequently, your vehicle will prompt you for a retest every 45 minutes. You have a five-minute window to complete the retest. While you are not obligated to pull over, it is often the safer choice to ensure your focus remains on the road.

With rolling retests, your car will not shut down while you’re on the road, as this would pose safety hazards. Instead, if your IID registers a positive sample (not necessarily indicating intoxication – products like mouthwash, perfume, cologne, or hand sanitizer can trigger positive readings), it will typically record a violation, activate your car’s alarm, or turn on its lights and horn. When this occurs, it’s essential to pull over, turn off the ignition to silence the alarms and follow the device’s instructions. Some IIDs may require you to wait briefly before restarting your car.
