3 dangers of a mandatory ignition interlock device (IID)

On Behalf of | Apr 13, 2023 | DWI Defense

If you’re charged for driving while intoxicated (DWI), one of the consequences may be an ignition interlock device (IID). When installed in your car, you’ll have to provide a breath sample every time before driving. 

IIDs can greatly affect your daily life, and they can also be a source of embarrassment. This is why you need to fight your DWI charges vigorously to avoid this costly punishment. Below are a few other reasons why you wouldn’t want to get stuck with this device:

1. An IID is expensive

Once the court orders that you use an IID, you will assume all costs of purchasing or renting the device, installation, service fees, maintenance, repair and other charges. Therefore, depending on how long the court orders you to install the device, the costs may quickly add up to thousands of dollars.

2. It can cause distracted driving

An IID will lock the car’s engine until you provide a clean breath sample. However, you may also be required to provide retests while actively driving. When taking these “rolling retests,” you will have to hold the device in your hand and perform a new breath test to keep going. Therefore, using the IID can distract you while driving and put you and other road users at risk of an accident.

3. You may be unable to start your car

Your vehicle may fail to start if the IID detects alcohol on your breath. While you may not have been drinking, the IID may give an incorrect reading. For example, this may happen due to alcohol in foods, toothpaste, mouthwash and even hand sanitizer. When this happens, you won’t be able to drive your car despite being sober. 

Being ordered to use an IID in your vehicle is one of many potential penalties after a DWI conviction. Seeking legal assistance when fighting these charges can increase your chances of obtaining a favorable outcome.
