If you are convicted of DUI or DWI in the state of Maryland, the judge may order an ignition interlock device to be installed in your vehicle, and you will probably have some questions. For example, when testing, do you have to pull over to the side of the road? Is it possible to trick the device?
When an IID is required
Driving under the influence is a more serious charge than driving while impaired; in other words, the penalties are greater for DUI. However, both offenses may require you to pay stiff fines and enroll in alcohol or drug awareness programs. In addition, under certain conditions, your driver's license will be suspended or revoked, and an IID may be required for a second or third offense or even the first offense, if the judge feels circumstances warrant it.
How it works
The ignition interlock device is a cellphone-sized computer with a mouthpiece that is attached to the wiring in your vehicle. You must breathe into the mouthpiece, and if your blood alcohol content level registers at the programmed level-usually 0.02 percent or below-the car will start.
About those retests
As you drive, the IID will schedule random retests, so you will need to provide additional breath samples. Breathing into the mouthpiece will not require you to take your eyes off the road, however, so you can continue to drive. If you prefer, you could also find a safe place to pull over and stop the car, but it is not necessary. The IID will record the resultsof your retests and pass the information along to the proper authorities.
An experienced criminal defense attorney can tell you much more about the IID, including the fact that trying to trick the device does not work. People have tried everything from asking a friend to blow into the device to using the air escaping from a balloon to imitate human breath. The IID is well-programmed and will not succumb to attempts at trickery. Your best course of action is not to drink when you are planning to drive. The IID will report that you have passed the test and your vehicle will start. Over time, you may even begin to appreciate the device for its part in helping you stay sober.
