North Carolina Intox EC IR II Practice Exam

Which statement best describes readiness before starting a breath test?

The device must be warmed for ten minutes. The device must display a ready state that allows testing. The device must be in calibration mode. The device must be in standby error state.

Correct Answer:

The device must display a ready state that allows testing.

Explanation:

Readiness is shown by the device displaying a ready state that allows testing. This indication confirms the instrument has completed its checks and is in proper operating condition to accept a breath sample. If the unit is in calibration mode or showing a standby error, it is not ready to test, and results could be invalid. Warming up may be required, but readiness specifically means the display signals that testing can proceed.
