If you have ever heard about the ignition interlock device, it's likely because you have been charged with driving under the influence. This device, most simply put, is one that stops a vehicle from turning on if the driver has been drinking alcohol. It is typically issued by the court for drivers who have had multiple offenses related to drunk driving. Let's take a look at the ignition interlock device.
Drivers who have been issued this device are required to blow into it before they can start their vehicle. The vehicle cannot be started without an initial breath test. If the driver blows a clean sample of air into the device, then the vehicle will be able to start.
There are times when the device will begin to beep while the vehicle is in motion. This is what is known as a rolling re-test. It requires the driver to take another breath test while driving. If there is alcohol present during the re-test, the vehicle will signal the driver to pull to the side of the road. The device can make the horn blast and the lights flash until the vehicle is stopped.
Every breath test is sent to the authorities by the device. This means that every clean sample and every tainted sample that the driver provides to the device will be recorded and submitted to the local court or motor vehicle office.
As you can see, the ignition interlock device is an important piece of equipment that is used to curb impaired driving. This device prevents impaired drivers from being able to operate their vehicle after taking a breath test using the device in Maryland.
