What is an interlock device?

• A. A device that increases vehicle speed
• B. A breathalyzer that prevents vehicle start if intoxicated
• C. A tool that measures tire pressure
• D. A GPS tracker for vehicle location

Answer: (B)

An interlock device is a breathalyzer system installed in a vehicle that requires the driver to blow into it before starting the engine. If the device detects a blood alcohol concentration (BAC) over a predetermined limit, it prevents the vehicle from starting. This safety measure is often mandated for individuals who have committed offenses related to driving under the influence of alcohol. The primary purpose of the interlock device is to deter intoxicated individuals from operating a vehicle, thus reducing the chances of accidents related to impaired driving. The other options describe different types of devices that do not specifically relate to preventing impaired driving. For example, increasing vehicle speed, measuring tire pressure, or tracking vehicle location do not directly address the issue of alcohol consumption and its effects on driving safety. Therefore, recognizing the specific function of an interlock device is crucial for understanding its role in promoting safer driving practices.
