First Offense DWI- How does the DWI Ignition Interlock Device Work?

Most states in the US are making it mandatory to install ignition interlock device in their vehicles, especially the first-time DUI offenders. This is mainly because you can reinstate the driver’s rights that could be the result of the suspension of your driving license and installing the ignition interlock device will record the driver’s blood alcohol level before he/she starts the vehicle.

Functioning of the ignition interlock device

The first thing we need to know with the device is that different states follow different preset limit of the ignition interlock device and the usual BAC (blood alcohol concentration) preset limit is anywhere between 0.02% to 0.04%. The vehicles start if the driver’s BAC is below the preset limit and if the machine records a reading above the set limit the driver will have to wait for 30 minutes to re-start the vehicle.

But before actually starting the vehicle the driver has to blow into handheld device for at least 3 seconds, which gives the device enough time to record the breath sample and if the sample is below the preset limit the interlock device will beep and the driver can start the vehicle successfully.

How feasible is the ignition interlock device?

After ten minutes of driving the device will beep again to take your breath sample and ensures that the vehicle continues to operate. Depending on the court’s requirement the device will beep and record breath samples in every fifteen to thirty minutes while you are driving.

The reason for the device taking so many samples is to ensure that the DUI offender does not ask his friend to blow into the device to run the vehicle without any interruptions. And anyone who tries to fool the device, on the second sample recording if the IID does not receive the required sample it will start beeping continuously with the lights of your vehicle flashing and the horn will warn you that the vehicle will stop operating in a matter of seconds.

The time limit to install the IID in your vehicle depends on the court’s requirement and also this differs with every state. First time DUI offenders have to keep the device for a at least a year and this might be a costly affair too; the installation and maintenance of the device might burn your pocket.
