B.E.S.T. Interlocks - What is an Interlock?

An ignition interlock device or breath alcohol ignition interlock device (BAIID) is a mechanism, like a breathalyzer installed in motor vehicles. Before the vehicle's motor can be started, the driver first must exhale into the device; if the resultant breath-alcohol concentration analyzed result is greater than the programmed blood alcohol concentration, the device prevents the engine from being started.

At random times after the engine has been started, the BAIID will require another breath sample. The purpose of this is to prevent a friend from breathing into the device, enabling the intoxicated person to get behind the wheel and drive away. If the breath sample isn't provided, or the sample exceeds the ignition interlock's preset blood alcohol level, the device will log the event, warn the driver until the ignition is turned off, or a clean breath sample has been provided. A common misconception is that interlock devices will simply turn off the engine if alcohol is detected; this would, however, create an unsafe driving situation.
