Even first-time DUI offenders in Oklahoma can be ordered to install an ignition interlock device in their cars. If you have one of these devices in your vehicle, you are responsible for maintaining it and using it correctly. Failing to use the interlock device responsibly can result in further charges.
How to avoid an interlock device violation
Ignition interlock devices require drivers to take a breath test in order to start their vehicle. If you fail the initial test, you will be locked out of your vehicle for a set period of time and you may also get a violation. Ignition interlock devices usually register a failed test if your BAC level is .02, and you will get a violation if your BAC level is .08.
Your second responsibility with an ignition interlock device is to take a rolling retest. About 10 minutes into your drive, your device will start flashing or beeping to let you know it’s time to provide another breath sample. If you fail the second test or you do not take it at all, you may get a violation.
Tampering with an ignition interlock device
You can get into serious trouble if you tamper with your ignition interlock device so that it does not read your breath sample correctly. Letting another person blow into your interlock device in order to circumvent the system is also a serious violation. Other licensed drivers are allowed to use your vehicle after your DUI, but they must take the breath tests as well.
Be careful when sending your vehicle to the mechanic
People who are doing everything right after a DUI can sometimes get into trouble with their ignition interlock devices. Malfunctioning devices or car battery issues are two of the most common problems. You should also be careful when your car needs to go in for repairs. Make sure that the mechanical work is well documented and your mechanic is aware of the ignition interlock device.
