Saving lives with ignition interlocks

What is an Intoxalock ignition interlock device?

An Intoxalock ignition interlock device is a state-of-the-art breath alcohol monitoring device that integrates a fuel cell based breathalyzer with your vehicle’s ignition system. When a breath sample is submitted, Intoxalock tests the sample for the presence of alcohol. Using a fuel cell technology developed by Intoxalock for the ignition interlock industry, the device will display the breath alcohol concentration (BrAC) of the sample on the LED screen.* If the BrAC is below the legal standard for your state, the vehicle will start. If a violation is detected, the vehicle will not start until a safe sample has been provided.

Electronic monitoring [Home alcohol monitoring] may increase over time as states seek less expensive alternatives to imprisonment. The cost of imprisonment is about 6 times higher than the cost of electronic monitoring.

Ignition interlocks

“A wealth of research continues to show that drivers compelled to install ignition interlock device or IIDs in their vehicles tend to have far fewer alcohol-related crashes, than drivers who have had their license suspended after being convicted of a DUI offense. Not only that, as a study in contrasts, IIDs are more effective than other methods at reducing re-arrest among convicted drunk drivers and keeping them off the road.”

All 50 states have some sort of ignition interlock law. Fifteen states—Alaska, Arizona, Arkansas, Connecticut, Hawaii, Kansas, Louisiana, Nebraska, New Mexico, New York, Oregon, Tennessee, Utah, Virginia, and Washington—have mandatory ignition interlock provisions for all offenses. Illinois and Colorado’s laws are not mandatory for a first conviction, but there are strong incentives to install an interlock device [ignition interlock device, IID] on the first conviction.

Alcohol-impaired driving killed more than 10,000 people in the United States [in 2009], making driving while intoxicated (DWI) one of our Nation’s most important highway safety issues. Increasingly, states are using ignition interlocks [ignition interlock devices, IID] as a key part of their overall strategy to reduce the incidence of DWI and to save lives.

There is clear evidence that the ignition interlock device (IID), installed in the offender’s vehicle, is substantially more effective than license suspension in deterring DUI recidivism. The overall reduction in recidivism realized by ignition interlock device (IID) use is enhanced by increased duration of installation – a sanction effect not observed for license suspension.

Over 90% of ignition interlock [car breathalyzer] users reported that the device has been successful to very successful in preventing them from drinking and driving; over 90% also reported that the ignition interlock has been effective or somewhat effective in changing their drinking habits.
