The Use of Ignition Interlock Devices in Idaho

As of January 1, 2019 Idaho will mandate that judges order the installation of interlock devices as a penalty during sentencing in all drunk-driving cases, including first time offenses.

The new law will require that the offender pay for the device. The cost usually includes an installation fee and a monthly rental fee . Under the new law, the offender will be required to have the interlock device for one year, even for a first time offense.

It is important to speak to an experienced DUI defense attorney at Martens Law Offices P.C. in Boise, Idaho if you are charged with a DUI. What is an Ignition Interlock Device?

An ignition interlock device is a small device (about the size of a cell phone) that is installed in a car that measures a person's BAC level. If a person blows into the device and it registers a BAC level that is above a certain amount, the car will not start. The driver must also give breath samples during the drive. This prevents an intoxicated person from having a sober friend blow into it in order to start the car so he or she can drive away. Ignition interlock devices use fuel-cell sensor technology to detect alcohol. Devices can record data such as the test results for alcohol levels, engine stops and starts and any attempts to tamper with the device.

Potential Problems with Ignition Interlock Devices

The use of ignition interlock devices should curtail drunk driving and prevent individuals from driving when they are intoxicated. In addition, using them can help people who have been convicted of drunk driving show the court and prosecutors that they have stayed sober. However, there may be some potential problems with the use of such devices.

False positives: The devices may detect alcohol if a driver has recently used mouthwash that contains alcohol or if a person has eaten certain baked goods containing sugar and yeast, which have been known to cause low alcohol levels. Malfunctions: The devices use complex fuel-cell technology, and there is a possibility that the device could malfunction resulting in incorrect readings. Shared vehicles: If the person who is required to use the ignition interlock device shares a car with a spouse or another person, that other person will need to use it as well.
