Under Virginia law, ignition interlock devices are mandated as part of the DUI offender's sentence in specific circumstances. You must install an ignition interlock device on your vehicle if: 

  • you have been convicted of DUI with a blood alcohol content of .15 or higher;
  • you have been convicted of DUI for the second time; or
  • you have been convicted of DUI for third or fourth time (only if the judge grants you permission to continue driving). 


For an initial DUI conviction, you must put an ignition interlock system on your vehicle for up to 6 months. For any repeat DUI offenses that time period is extended to between 6 and 12 months.

Costs of an Ignition Interlock System

In addition to the requirement of installing the ignition interlock device on your vehicle, you will also be obligated to pay for the costs associated with the Ignition Interlock program. These costs vary depending on the county in which you were convicted of DUI.

Generally speaking, the cost of installing the device on your vehicle will cost a few hundred dollars. In addition, you will be assessed a monthly fee of around $30 to pay for the system that monitors your ignition interlock device. If you have any questions about the ignition interlock system or what your responsibilities are, your Virginia DUI defense lawyer should be able to answer them.
