An ignition interlock system is a device that is installed in the vehicle dashboard of a person's vehicle. You will also be required by the DMV to provide proof of SR22 Insurance before they will reinstate your driver's license.
How does the ignition system work?
The ignition interlock system is connected to a vehicle's starter system. The ignition interlock system can be set anywhere from .00% BAC to slightly higher levels, but typically not above .04% BAC. An ignition interlock system works by measuring the BAC of the vehicle's driver before and during the operation of the vehicle.
If the BAC registered by the ignition interlock system is higher than the preprogrammed level allowed, the vehicle will not start. The courts in each state determine the programmed level that will be set by the company performing the installation. Typically this level will be between .02% and .04% depending on the state law.
Also at random intervals while the vehicle is in operation, the ignition interlock system will require breath samples from the driver in order for the vehicle to continue operating.
What happens if a breath sample is not provided?
If a breath sample is not provided, or the sample that is registered by the ignition interlock system exceeds the limit that has been preset by the ignition interlock provider, the unit will record the occurrence, warn the driver and then start its alarm, which will consist of the lights flashing, horn honking, etc.
When it is time for a breath sample, the ignition interlock system will let the driver know that a sample is required. The ignition interlock system will allow enough time for the driver to safely pull to the side of the road before the sample must be given.
How much will it cost to install the interlock device?
The overall cost of installation, calibration and scheduled maintenance is the responsibility of the offender. An ignition interlock device will cost around $75 per month and a couple hundred dollars to be installed. Some states have programs that will subsidize the monthly cost if the offender can prove that they do not have the financial means to pay the monthly charges.
