Arrested for a DUI in Ventura County? What to Expect...

What Are Ignition Interlock Devices?

The Latest Deterrence in Drunk Driving

Along with a night in jail, extensive classes, probation, and mandatory self-help meetings, you will likely need to install an Ignition Interlock Device (IID) in your vehicle, even if it is your first DUI, and even if you were underage when you were convicted.

The device is wired to your ignition and alarm systems, blocking you from starting your car if you are under the influence and blocking you from becoming intoxicated during your drive. As the common experience is that of a burden and nuisance, it offers first and subsequent offenders the change in lifestyle that is needed to overcome the habit of drinking and driving, promoting their chances at obtaining another DUI offense in the future.

How Long Do I Need to Keep the IID Installed?

Depending on the circumstances surrounding your case, the length may vary. However, the IID is usually a DMV requirement and not something ordered by the court. That said, the lengths are fairly predictable. Once you have you license back, it will be automatically restricted to only being able to drive a vehicle with the IID installed. The lengths can be broken down as followed:

  • 1st DUI: Usually a length of 5 months
  • 2nd DUI: 12 to 18 months
  • 3rd DUI: 18 to roughly 24 months

How Does It Work?

The following rules apply no matter how many DUI convictions you've had or how long the duration of your IID installment:

  • The individual driving the car must be the same individual testing into the device
  • Until the restriction on your license is lifted, you will not be able to operate a vehicle that doesn't have an approved IID installed. For this reason, you may need to install it in two vehicles, but certainly in your primary vehicle, if you have more than one.

Every time you want to start your car, it will make you blow into the device as a BAC test. It will then ask you to do it again 5-10 minutes down the road. For every 30 minutes after that, the device will periodically ask you to test. This is to deter the event of having a sober friend blow into the vehicle just to get it started, while an intoxicated driver takes over from there and drives home. The periodic tests afterward ensure that a driver does not start the drive sober but then become intoxicated during the drive.
