Use of Technology to Combat Drunk Driving—Ignition Interlocks

The DUI defense lawyers at the law firm of Alpert Schreyer understand that being convicted of driving under the influence comes with serious consequences, such as loss of freedom, loss of money, loss of driver’s license, insurance, etc. They want you to be aware of technology available to be used as part of a DUI offender’s punishment and to help prevent subsequent incidents of drunk driving.

According to the Governors Highway Safety Association (GHSA) website,, driving while impaired is not only one of the most often committed crimes in the U.S.; it is also one of the most deadly. Over 10,000 individuals have lost their lives in traffic crashes in which alcohol was a factor. This is why both law enforcement and prosecutors are very aggressive when trying to obtain a conviction after an alleged DUI offense.

One of the punishments that a DUI offender may receive on conviction or in accordance with probation is an ignition interlock device. Such devices are becoming more and more common and are used to disable a vehicle’s motor if the presence of alcohol is detected. They detect the presence of alcohol by analyzing the driver’s breath.

Most states currently have some type of ignition lock program in place and judges can order drivers convicted of DUI to have ignition interlocks installed in their vehicles.

The device is typically installed in the glove compartment. When ready to drive, you blow into a handheld sensor unit located on the dashboard. If your breath indicates an alcohol content over a preset limit, your vehicle will not start. The device also contains a computer chip capable of recording your blood alcohol content. This record can be downloaded for the benefit of the court. It also shows whether the device has been tampered with.

While an ignition interlock device is not ideal, it may be necessary when fighting for reduced charges after a DUI arrest. The Calvert County DUI attorneys at Alpert Schreyer have extensive experience representing those who have been charged with driving under the influence and can investigate the details surrounding your arrest and develop an aggressive defense on your behalf.
