If a suspect vomits during the observation period what must be done?

• A. Restart the observation period
• B. Continue the test
• C. End the test
• D. Take a five-minute break

Answer: (A)

The observation period must be conducted under defined, uninterrupted conditions, and an interruption such as vomiting breaks those conditions. Vomiting adds a new, altered baseline of physical state and behavior, so the original window can no longer reliably represent the suspect’s normal presentation during that period. Restarting the observation period after the individual has recovered and the area is ready ensures the assessment begins from a clean slate and under the proper controlled conditions. This keeps the results valid and defensible. Continuing would carry the interruption into the evaluation, risking inaccurate results. Ending the test ends the assessment prematurely, which isn’t appropriate. A five-minute break doesn’t reset the observation window, so it wouldn’t satisfy the requirement to re-establish a valid baseline.
