Which message would appear if mouth alcohol is detected?

• A. Mouth alcohol
• B. Breath sample
• C. Error
• D. Ready

Answer: (A)

Mouth alcohol triggers a specific alert because alcohol in the mouth can contaminate the breath sample and inflate the reading. When the device detects this, it displays a message indicating mouth alcohol, signaling that the current result is not valid. The correct action is to stop the current test, wait for the mouth alcohol to dissipate (often after rinsing the mouth and a short delay), and then take a new breath sample so the result reflects true deep-lung alcohol. Other messages like a generic breath sample, ready, or error indicate different conditions and do not warn of mouth alcohol contamination.
