Debunking the myths about ignition interlock devices

When you are facing a DUI or DWI charge in North Carolina, your driving privileges are in immediate danger of suspension, to say nothing of the other penalties and fines you may face. One method the state uses to help reduce drunk driving is the installation of ignition interlock devices. In order to reinstate your driver’s license, the court may order an IID for installation in your vehicle.

If you are a first offender, you might not know much about IIDs. However, the criminal defense attorney you engage can set you straight on some of the tall tales going around about these devices.

Certain foods may skew IID results

While this is true, it is not meant to trip you up. Some foods may contain a little alcohol, as do certain medicines and mouth washes. Since you activate the IID by breathing into it, the device will register the alcohol level in your system. To be safe, wait at least five minutes after eating or taking medication before you try to use the IID. Doughnuts and other pastries that contain yeast can also skew results. A good tip is to rinse your mouth out with water after eating.

Temperature and altitude issues

Perhaps you heard that temperature and altitude can adversely affect the reading on ignition interlock devices. However, they are made to withstand temperatures from minus 49 to 185 degrees and will operate efficiently in altitudes up to 11,000 feet.

Rolling re-tests and safety

Once you have pass your IID test and start to drive, there will be sporadic rolling re-tests during which you must blow into the device, the object being to ensure that you are still sober. Some people think that the car will simply stop dead during a re-test, but this is not true. The car will continue to run, and the information it records will be sent to a probation officer or judge.

Helping you deal with DUI/DWI

Just as an ignition interlock device keeps you driving — but not driving drunk — your criminal defense attorney will fight for your rights, help you retain your driver’s license and work diligently to obtain the best possible outcome for your case.
