Driven by Safety's Vehicle Drive Module is a Bluetooth-controlled interlock that is connected to the vehicle's ignition system, allowing the vehicle to start when paired with a phone that has an active SOBRDRIVE or CheckBAC Drive subscription.
 
With CheckBAC, the default setting is for the vehicle to require a BAC test to start every time.
With SOBRDRIVE, the default setting is for the user to use it only when they need. It will allow the vehicle to start, until the user voluntarily sets when they want a driver to take a BAC test, such as a night out or loaning the car to a teenage driver. 
 
*Requires active subscription and Breathalyzer.
