How a DWI can lead to driving with an ignition interlock device

If you get convicted of a DWI or refuse a breathalyzer test when law enforcement requests, the courts may require you to drive with a restricted license. You may also have to install an ignition interlock device as a condition of probation if this is your first or second offense.

You must also follow several restrictions while using these devices.

How an ignition interlock device works

An ignition interlock device is a small electronic device that sits inside the driver’s compartment and connects to your vehicle’s ignition system. The machine is a portable breathalyzer that you breathe into to measure your blood alcohol content. You must have less than the required amount of alcohol in your system for the device to allow your car to start.

Laws regarding ignition interlock devices

With an ignition interlock device in your car, you must follow the additional laws regarding the equipment to avoid more penalties. Be aware of the following guidelines:

1. Another person can not blow into the device on your behalf, nor can you ask another person to do so
2. You must not tamper with or remove the device from your car
3. You may not rent or borrow a car without an ignition interlock device
4. With court approval, you may drive an employer’s vehicle that does not have a device as long as the employer is aware of your driving restrictions

Ignition interlock devices allow you to have supervised driving privileges after a drunk driving conviction. Following the probation requirements while using the machine enables you to regain your full driving privileges as soon as possible.
