What is an Ignition Interlock Device?
An ignition interlock device or breathalyzer is installed discreetly under the vehicle’s dashboard. Before the vehicle can be started, the driver must exhale into the device. If the breath-alcohol ratio that is analyzed by the device is greater than the blood alcohol concentration programmed into the system, the Ignition Interlock Device prevents the engine from starting until a clean test is provided.
At various times after the engine is running; the Ignition Interlock Device will require further breath samples. The purpose of this extra security is to prevent a friend from breathing into the device in place of the intended driver, thus enabling the intoxicated person to continue operating the vehicle even though they might be impaired.
LifeSafer Ignition Interlock devices contain a specially made fuel cells that converts the alcohol that may be present in a person’s breath into an electric current. This current can then be measured and converted into an alcohol equivalent reading.
