An ignition interlock device is machine that tests your breath before you start your car.  It is about the size of a pack of cards and is installed so that the driver can access it before he or she starts his or her car.  O.K., why would anybody want one of these?  You would only get an ignition interlock device, or probably are only asking about it, if you have been charged with DUI.  If you are convicted of first offense DUI in Virginia, you must have one of these devices installed if you ask for a restricted license.  If your blood alcohol was .15 or above, you  must get one of these devices installed for at least six months whether or not you get a restricted license.  If your blood alcohol level was between .08 and .15, your license will be suspended for one year.  You can get a restricted license but it will come with the ignition interlock device.  You can go back and ask the judge to have the ignition interlock device removed once it has been installed for six months and you have had no problems.  You cannot install the ignition interlock device yourself.  You must go to a contractor who installs the device and calibrates it monthly.  It should be no surprise but you will have to pay for the device to be installed and its monthly calibration.  If you have any questions about ignition interlock devices and how they apply to DUI’s, please contact Gene Cox at coxfedlaw.com.
