Drinking and driving often come with serious consequences for those who face DUI charges in Missouri and in other states across the nation. If you face a DUI charge and have previous drinking and driving convictions, the penalties may include mandatory use of an ignition interlock device, according to the Missouri Department of Transportation.
Ignition interlock devices can help ensure you do not commit subsequent drinking and driving violations. Not only is it important that you understand how IIDs work so you are in compliance with the law, but it may also help restore your driving privileges.
What is an interlock device?
An ignition interlock device is essentially a breath test device installed directly into your vehicle. Equipped with a dashboard monitor and GPS system, the device requires you to exhale into a tube connected to the device where it measures your blood alcohol content level before the car will start.
The device tracks and stores critical information, including start-up attempts, BAC levels and lockouts. Rolling retests, which alert you to exhale into the tube periodically during the drive, are also required. If at any time your BAC level reads too high, the car will slowly power down.
What do you need to know?
Once a state-approved dealer installs your interlock device, you must continue to take your vehicle in for monthly maintenance appointments. At the appointment, the technicians will ensure your device is calibrated properly, download stored data and include the information in a monthly monitoring report. It is here that the state determines whether any violations or tampering have occurred.
Although you must pay for the installation fee, maintenance appointments and other expenses for the interlock device, the machine can help to restore your driving privileges and minimize your risk of getting further DUI charges.
