Many countries are requiring the ignition interlock as a penalty for drivers convicted of driving under the influence, especially repeat offenders. Some politicians in Sweden, Japan, Canada, the U.S. and other countries have called for such devices to be installed as standard equipment in all motor vehicles sold.
As of 2009, almost all 50 states have laws permitting the imposition of IID’s as sentencing alternatives for drunk drivers. Most U.S. states now permit judges to order the installation of an IID as a condition of probation; for repeat offenders, and for first offenders in some states, law may mandate installation.
After the completion of the term, take your vehicle back to have the device removed (typically at no cost).
According to a study done by the International Council on Alcohol, Drugs and Traffic Safety (ICADTS), ignition interlock devices, as well as monitoring, led to a 40-95% reduction in conviction rate of people who were previously arrested for DUI.
Yes. The devices keep a record of the activity on the device and the interlocked vehicle's electrical system. The state requires that you bring your vehicle back to the installation location every 30 to 60 days after the installation, so that the device is checked and a report is sent to the state, or, the record, or log, is printed out or downloaded each time the device's sensors are calibrated, commonly at 30, 60, or 90-day intervals. Authorities may require periodic review of the log. If violations are detected, then additional sanctions can be implemented.
The costs of installation, maintenance, and calibration are generally paid for by the offender and are typically around $75 per month.
If the breath sample isn’t provided, or the sample exceeds the present blood alcohol level, the device will log the event, warn the driver, and then start up an alarm until the ignition is turned off, or a clean sample is provided.
No. An interlock device cannot turn off a running vehicle as it could create an unsafe driving situation. All that an interlock can do is interrupt the starter circuit and prevent the engine from starting.
Yes. At random times after the engine has been started, the IID will require another breath sample to prevent a friend from breathing into the device.
The penalty for driving a vehicle equipped without the device is typically an additional suspension of driving privileges.
The driver sentenced under this law cannot drive any vehicle that does not have this device installed in it. The DMV imprints a notation on the driver's license stating that the person shall not operate a motor vehicle unless it is equipped with an interlock device and enters this requirement in the person's driving record.
Starting the car in some way other than blowing into the device, is an additional suspension of driving privileges.
Failure to have an ignition interlock installed when ordered by a judge could result in an additional driving privilege suspension. The device stays on the vehicle(s) until completion of the time period imposed by the judge.
If your license was suspended because of a DUI offense, the court may require you to get an ignition interlock device to fully restore your driving privileges.
The driver must exhale into the device before the vehicle is started. If the resultant breath-alcohol concentration analyzed result is greater than the programmed blood alcohol concentration (BAC), the device will prevent the engine from starting.
Similar to a Breathalyzer, an IID is installed into a motor vehicle’s dashboard.
