The second detection element can be operable to detect a level of the intoxicant. The second detection element includes a different type of element than the first detection element. The second detection element can have greater accuracy than the first detection element. The control module to selectively operate the second detection element based on the signal received from the first detection element, and to indicate whether the level of intoxicant in the user's breath exceeds a threshold.
