What is the waiting period (observation) for the intoxalyzer?

• A. 30 minutes
• B. 15 minutes
• C. 60 minutes
• D. 45 minutes

Answer: (A)

The main idea is to ensure the breath test result is accurate by giving time for any residual mouth alcohol to dissipate and for recent intake to not distort the reading. The standard observation period before using the intoxalyzer in this protocol is 30 minutes. This duration helps ensure the sample reflects the true blood alcohol level rather than contamination from substances in the mouth or recent consumption. Once that 30-minute window has passed, the breath sample is collected and the reading is considered more reliable. Shorter periods might not remove mouth alcohol effectively, and longer periods aren’t required by this procedure, so 30 minutes is the specified waiting time here.
