What is the Ignition Interlock System?

The Ignition Interlock System is a device installed in vehicles that requires the driver to provide a breath sample before the engine can start. This process ensures that the individual has not consumed alcohol and is capable of driving safely. The requirement for a passing breathalyzer test to start the car helps curb instances of drunk driving, particularly for individuals who have previously been convicted of driving under the influence (DUI) offenses.

This system is often mandated by the court as part of a penalty for DUI offenses, serving as a preventive measure to reduce the likelihood of repeat offenses. It functions by acting like a breathalyzer; if the driver blows over a specified limit of blood alcohol concentration (BAC), the system will not allow the vehicle to start.

The other choices do not accurately describe the Ignition Interlock System. A restricted time frame for driving refers to limitations placed on a driver's license but does not specify the alcohol-testing aspect. A suspended license entails a complete removal of driving privileges rather than monitoring to ensure safe driving behavior after a prior offense. Thus, the correct answer provides a clear understanding of the function and purpose of the Ignition Interlock System.
