Regardless of whether you have multiple DUI related convictions or just one on record, it is possible that a judge may still deem it necessary for you to install an ignition interlock device.
These devices are somewhat difficult to work with, and many people find their mid-driving demands for breath samples to be taxing at best. But there are even more aspects about them that people find unfortunate.
Driving on a new license
The Pennsylvania Department of Transportation discusses laws and information regarding ignition interlock devices. For example, you must carry a special license for the duration of your time with the interlock device. This is so you do not simply borrow a device-free car during this time period.
This license looks very visually different from a normal license. It tips officers off right away to the fact that you should only be driving a car with an interlock device, and you may face serious repercussions if you are not.
The existence of false positives
However, false-positive results can and do happen, too. These devices are not infallible and can in fact generate false positives based on numerous other factors. This includes medical conditions like GERD, foods like bread or protein bars, hygiene products like mouthwash, and medications like albuterol.
Paying for the device
On top of that, you have to pay for the device both in terms of maintenance and installation. The Department of Transportation estimates that this will cost anywhere from $900 to $1300 a year on average.
Needless to say, these combined factors make it clear why exactly you may want to avoid that DUI conviction in the first place.
