Ignition Interlock Myths

Ignition interlock requirements are becoming more prevalent in the U.S. for those who make the choice to drive while under the influence of alcohol. The rationale behind these devices is research-based, providing behavior modification for those who may not understand the seriousness of driving while drunk. Unfortunately, not everyone understands how the devices work, and there are certain myths and rumors about IIDs that are simply untrue.

Myth: Ignition Interlocks will disable a vehicle in motion.

Fact: The purpose of these devices is to disable a vehicle before it starts, eliminating the opportunity to drive while intoxicated. The “rolling re-test” that is administered will not stop a car while it is in motion.

Myth: Ignition Interlock tests can be faked by others.

Fact: While it is possible to have a friend or another person blow into the device upon starting a vehicle, these devices will also require a test while driving. Additionally, ignition interlock devices are now integrating video and camera technology in order to reduce the ability of a convicted offender to circumvent the testing process.

Myth: Ignition Interlock devices are sensitive to foods, perfumes or other chemicals besides alcohol.

Fact: Alcohol-specific technology provides the most accurate experience for offenders and reporting purposes. Additionally, an initial ignition interlock test includes the ability to test again after a false positive reading, if necessary.

Myth: Ignition Interlocks are unnecessary and costly for convicted drunk driving offenders.

Fact: A person who is convicted of a DUI or DWI charge has likely driven drunk around 80 times prior to being arrested. The costs associated with drunk drivers are high, especially considering court costs that everyone shares. These facts alone show that the devices are not only economic, but, are saving lives each day.

Ignition Interlock devices provide a level of security in deterring a person from driving drunk, as well as eliminating the potential for more irresponsible behaviors from those who have already been convicted of a DUI or DWI charge.
