Ignition Interlock Devices and Calibration

It's important to remember that one requirement of the California DMV and ignition interlocks system plans for many states include a mandatory calibration. You will need to take your vehicle to the approved installer of ignition interlock devices and have it checked, usually once every 60 days. This calibration is a must and cannot be avoided. Failure to maintain the interlock device can at the least be seen as a violation of the terms of your state's ignition interlock program, and at worst could be interpreted in an extreme case as an intentional defeat of the interlock system (depending on the circumstances of your case). Don't ruin your second chance by neglecting the calibration of your ignition interlock!
