DRIVER The Interlock goes one step further to ensure a sober driver is behind the wheel. The intelligent camera module can detect a change in the driver of the vehicle between the initial test and driving. When a change is detected it will require a breath sample to confirm sobriety.


Fast use

The Interlock  has the fastest warm-up time in the industry. In fact, if it is above freezing, the Interlock  will be ready for use in less than 4 seconds. With an operating temperature range of -40 F to 185 F, the Interlock  will be ready to use when it is needed.

 Intuitive and Discreet

The Interlock   guides the user with easy-to-understand messages and colored LED lights. The rear-mounted mouthpiece and sleek design of the Interlock  makes the in-car breathalyzer less noticeable.


 Additional Innovations

To reduce unnecessary lockouts, the ignition interlock device is able to distinguish breath alcohol from mouth alcohol,* such as mouthwash. The  interlock also includes highly advanced bypass or tamper protection that will record any attempts in the data log for use by the monitoring agency.

*Advanced features are optional in WA & OR – check with your court to find out if they have approved it in your jurisdiction!
