Tampering with Ignition Interlock in Virginia is a Crime
An Ignition Interlock is a device that is connected to the ignition of a vehicle that prevents the vehicle from starting if it detects alcohol. The Ignition Interlock requires the user to blow into the device before starting the car and at random intervals while the car is being operated. If the Ignition Interlock detects alcohol, the car will not start. If the driver fails to take a re-test while operating the vehicle or the Interlock detects alcohol during a retest, the horn will sound and the lights will flash, requiring the driver to pull over and stop the vehicle. Va. Code §18.2-270.1(A).
