The article explains the purpose and use of ignition interlock devices for drunk-driving offenders.
Abstract
By July 1, 2004, under Federal mandate, every State is required to have ignition interlock laws on the books. To date, 43 States have complied, with others having pending bills in the legislature. An ignition interlock helps offenders monitor how much they’ve had too drink. If they’ve had to much to drink, the vehicle will not start. The interlock devices are wired into a vehicle’s ignition system and require a driver to deliver a passing breath sample before the vehicle can be started. The majority of States require the fail limit to be at least .025, less than one-quarter the legal alcohol limit in most States. The device randomly retests the driver once the vehicle is started. Interlocks record engine starts and stops, breath test results, attempts to disconnect or tamper with the device, and more. Those required to use ignition interlocks varies by State, such as first-time offenders and repeat offenders. In some States, an automatic 6-month license suspension is followed by 6-months of using an interlock device. In all States, unless indigent, offenders must pay the costs associated with having the device installed and removed. The interlocks are effective devices in keeping drunk drivers off the roads; they can prevent impaired driving. These devices can help modify one’s behavior. However, behavior modification takes time; some have recommended requiring offenders to use the devices for 12 to 24 months. The longer it’s in, the less recidivism seen.
