How long does it take for residual alcohol to diminish below significant levels?

• A. 5 minutes
• B. 10 minutes
• C. 30 minutes
• D. 15 minutes

Answer: (D)

Residual mouth alcohol can distort breath test results, so the testing protocol allows a window in which this alcohol dissipates to levels that won’t significantly affect the reading. About 15 minutes is enough time for any alcohol in the mouth, on the teeth, or in the saliva to diminish, making the breath sample more reliable. shorter intervals like 5 or 10 minutes may still leave residual mouth alcohol, while 30 minutes is longer than necessary. It’s important to remember this focus is on mouth alcohol, not the slower process of metabolizing alcohol in the bloodstream, which takes longer.
