Facing a driving under the influence (DUI) charge in Tennessee can be a scary ordeal. A negative outcome can affect your opportunities for work, education and housing in the future. One of the most restrictive and costly consequences of a DUI conviction is the mandatory installation of an ignition interlock device (IID) in your vehicle.
While not every DUI case ends with an IID installation, understanding how these devices work is crucial. Doing so can help you better prepare to fight this outcome in your upcoming trial.
How the ignition interlock device works
To prevent alcohol-impaired driving, an IID is often required as a condition of a restricted license or following a DUI conviction. The device connects to your car’s ignition system and prevents it from starting if your breath alcohol concentration (BrAC) is too high (0.02 for Tennessee).
For many, the most daunting aspect is the timeline. The minimum duration for the IID program is 365 days and can increase if you are a repeat offender. While you have the IID in your car, you may only be permitted to drive for work purposes or family emergencies.
The risk of false positives
One of the most frustrating challenges of the IID program is the device’s sensitivity. It may flag alcohol content from food and dental hygiene products, resulting in false positives. The device may misidentify these traces as alcohol consumption, potentially extending your license suspension. Compiling the necessary evidence to challenge these fails can help you protect your record from unfair penalties.
The financial implications
Being in the IID program is a long-term financial commitment. In Tennessee, the driver typically shoulders most of the costs, including device installation, license fees and monthly calibrations. Moreover, individuals need to bring the vehicle to a service center every 30 days for maintenance. Even if you are in the program for the minimum of one year, the costs can add up over time.
Protecting your driving rights
An IID requirement is a heavy penalty that disrupts your daily life and drains your finances. However, it does not have to be the outcome of your DUI charge. Working closely with a legal professional can help increase your chances of reaching a fairer outcome. Whether that means fighting to have the charges dismissed or making sure that your time in the IID program is as short as possible, a lawyer can protect your rights every step of the way.
