PreLock-90 Alcohol Ignition Interlock
Our PreLock 90 alcohol ignition interlock is a device that checks the driver’s blood alcohol content before they start the vehicle.
The PreLock 90 alcohol ignition interlock checks the driver’s breath alcohol level before every trip and allows the engine to start only if the test result is negative.
This is a state-of-the-art alcohol interlock. It already complies with the latest EU directives as well as strict requirements for government approvals, such as CENELEC EN 50436-1 and EN 50436-2.
This speaks to the use of proven system components, reliable breath alcohol analysis, and system security.
