What is an Interlock System?
An ignition interlock device or breath alcohol ignition interlock device (IID and BAIID) is a mechanism, like a breathalyzer, installed on a motor vehicle’s dashboard. Before the vehicle’s motor can be started, the driver first must exhale into the device; if the resultant breath-alcohol concentration analyzed result is greater than the programmed blood alcohol concentration, the device prevents the engine from being started.
Am I responsible for the cost of the device?
The cost of the device is typically borne by the offender. There is an installation charge and monthly monitoring fee. Although the cost will vary according to state, MADD estimates it costs approximately $70 to $150 to install and around $60 to $80 per month for device monitoring and calibration.
Is it discreet?
Ankle trackers come in various different sizes, wearing long pants or jeans easily covers most of the units on the market today. Interlock devices can are discreetly installed with the main component below the dash and a small detachable handset that can be removed and placed out of view when the vehicle is parked.
What if my ankle device comes undone?
In the unlikely event that this were to happen, you would want to contact our office immediately. This would trigger an alarm and send an alert to your parole officer indicating that you are tampering with your device and that would likely be a violation of your parole. If it was a failure of the device, and not a result of tampering, the issue could be resolved with local law enforcement and Westco would replace the device within 24 hours.
