- DThe device will notify law enforcement immediately, and the driver will be arrested.
Show answer & explanationAnswer & explanation
Correct answer: A. The device will prevent the vehicle from starting.
If an Ignition Interlock Device (IID) detects alcohol above a pre-set limit, it will prevent the vehicle from starting, requiring the driver to wait and retest until they pass.
Why the other options are wrong
- B. The primary purpose of an IID is to prevent the vehicle from starting if alcohol is detected.
- C. The driver can usually retest, but not necessarily three immediate attempts, and a warning isn't the primary outcome; prevention of start is.
- D. While failures are recorded and reported, immediate arrest is not the typical first response to a single failed test.
Ignition Interlock Device (IID)
An Ignition Interlock Device (IID) is a breath alcohol analyzer installed in a vehicle that prevents the engine from starting if the driver's breath alcohol content (BAC) exceeds a pre-set limit.
- Mandatory for DWI convictions in NY.
- Prevents vehicle start if alcohol detected.
- Requires 'rolling retests' while driving.
- Records all test results and violations.
Memory trick: Blow to go, but if drunk, then no.
