Vehicle Ignition Interlock Systems
What Is an Ignition Interlock System?
An ignition interlock is a sophisticated system that tests for alcohol on a driver's breath. It is a device that requires a vehicle operator to blow into a small handheld alcohol sensor unit that is attached to a vehicle's dashboard. The car cannot be started if a BAC is above a preset level (usually .02 to .08 BAC). Alcohol safety interlocks that meet the standards issued by NHTSA not only require a test to start the engine, but also require a test every few minutes while driving. Called the "rolling or running retest," it prevents a friend from starting the car and then allowing an impaired driver from taking over the wheel (NHTSA guidelines call for only one subsequent test). With modern safeguards, alcohol safety interlocks are extremely difficult to circumvent when properly installed and monitored every 15, 30, or 60 days.
When used by the courts or state motor vehicle departments in conjunction with a monitoring, reporting, and support program, the ignition interlock system provides DWI offenders with an alternative to full license suspension. Its use has spread rapidly across the country. 
Quest Guard complies with all local and state regulations regarding the proper installation, maintenance, and calibrations of our Interlock systems.
In today's modern world where high speed and technology dictate our everyday lives, an awareness dulled by alcohol exposes us and others to many risks. We have developed a highly reliable Interlock system for in-vehicle use or wherever it is deemed necessary to prevent an alcohol impaired person from operating a motor vehicle, heavy equipment or machinery. The Interlock system not only protects the operator of the vehicle, but helps to safeguard others and prevent the loss of expensive equipment.
Our Interlock system with its microprocessor-controlled operation exceeds NHTSA specifications. The heated electrochemical fuel cell and breath sample path ways provide an extremely reliable and accurate measurement.
Our Interlock system is designed with an absolute 100% detection of vehicle operation without a breath sample, making it the most dependable and precise ignition interlock device offered on the market today.
