National interlock systems

Low Cost Interlock keep you and your family safe on the roads every day of the year.

If a driver’s license was suspended for a DUI offense, the court may require him to get an ignition interlock device to prevent a vehicle from starting if his BAC exceeds 0.05%. The requirement may vary per state.

The interlock ignition device won’t allow a vehicle to start if the driver didn’t pass the breathalyzer test.
