No. An Interlock does not shut off a vehicle's engine, or stop it abruptly in its tracks. If a Retest is failed, or if the Retest is not presented when required, a violation will be recorded. The vehicle's horn may sound and the lights may flash until either the breath test is passed or the vehicle is turned off by the driver.
I just recently got my device removed and I didn't have one issue or problem in the entire 6 months! Guy was extremely friendly, helpful and professional and the staff in the office is always pleasant when I call. I will definitely be recommending this company in the future! Thanks
