Ordered to Have an Interlock Mechanism Installed? Roanoke DUI Law Firm Can Help

If you or someone you know has been convicted of DUI, you may have heard about ignition interlock devices, mechanisms that are designed to prevent a car from starting if the driver has a breath alcohol content (BAC) over a preset limit. In Virginia, this limit is 0.02 percent, and the interlock mechanism must be equipped with the ability to perform a rolling retest and to electronically log blood alcohol content during ignition, attempted ignition, and rolling retest. Virginia courts will order the installation of an ignition interlock mechanism for a first and any subsequent DUI convictions as a condition for any restricted license. The minimum period for this requirement in Virginia is 6 months. Depending upon the circumstances, it may be for the entire period of time of any restricted driving privileges. If the court requires the installation of an ignition interlock mechanism, it will also prevent the offender from operating any motor vehicle that is not equipped with such a system during the time that the restriction is in effect. A restricted license will also be ordered for the period during which the interlock system is installed.


Typically, the offender will have to pay fees to have their license reinstated, and the cost of having the ignition interlock mechanism installed, which may vary anywhere from $50 to $200, depending upon the type of vehicle or if the installation takes extra time. There is also a monthly rental fee for the device, usually $50 to $100 per month.

Other Requirements

You will also have to come in for scheduled appointments to have your ignition interlock device calibrated, usually every 60 days, and to have the records downloaded and the device reset so you can continue driving. The offender is responsible for the maintenance expenses associated with the device, as well as fees associated with downloading the data. Failure to maintain the mechanism can be viewed as a violation of the ignition interlock program. Do you have questions regarding ignition interlock mechanisms used in Virginia? Robert F.
