DOT Breath Alcohol Technician (BAT) Course Practice Test

When the BAT runs out of mouthpieces prior to a scheduled DOT alcohol test, what type of test is this considered?

Uncompleted Refusal Cancelled None of the above

Correct Answer:

Uncompleted

Explanation:

If the collection can’t be completed because the necessary mouthpieces aren’t available, the test is considered uncompleted. This isn’t a cancellation or a refusal—no one is refusing to test, and the process isn’t halted by a decision to cancel. It’s simply that the equipment needed to finish the test is missing, so the testing process cannot be finished. When mouthpieces are available again, the test can be started or resumed, and the situation is documented so the status reflects that the test was not completed due to the equipment issue.
