Twenty Minute Observation Period

If you were arrested for DUI and took the breath test, the attorney you hire should use innovative techniques to fight the DUI case. One of the best ways to fight a DUI breath test case is to gather evidence about what occurred during the twenty minute observation period before the breath test. In some jurisdictions, video equipment is set up in the breath testing room.

The video is the best evidence of whether the arresting officer watched the defendant for the entire 20 minute period before the breath test. If not, the breath test results could be thrown out by the judge making a dismissal of your DUI charges more likely.

Update: The Hillsborough County Sheriff's Office moved the central breath testing facility in November of 2011 and failed to install cameras in the new breath testing facility. Video of the 20-minute observation is often available in other jurisdictions. If the officer brings to the Intoxilyzer 8000 machine to the scene, then the twenty minute observation period is often preserved on the roadside video.

?The 20 minute obervation period is oftne called the "Wait or Deprivation" period. The purpose of the observation period is to provide a reliable way to minimize the chance that a contaminant will artificially inflate the breath test reading. Those contaminations can occur becuase of regurgitation of stomach contents, vomitus, burping or consumption of unknown substances.

Require "Close and Continous" Observation of the Test Subject

The criminal defense attorney should point out the importance of close and continuous observation of the test subject. Without the close and continous observation of the defendant, the sources of contamination might falsely elevate the reported BrAC results or artificially raise a reported amount of alcohol well beyond the per se limit.

For this reason, the best practices for testing protocols require that the Wait, Observation or Deprivation period is closely and continuously observed. If the period is not conducted properly, then the results obtained, regardless of an .02 agreement, are inherently unreliable, and should be disregarded by the court.

The officer should be asked about what he did during the 20 minute period before the beath test. If the officer was in the room, but spent the time attending to paperwork or setting up the breath testing machine without monitoring the defendant, then the best practices were not followed. The ideal time to ask the officer these questions is at the formal review hearing which is conducted within 42 days of the arrest.

In many of these cases, we've seen officers on video doing paperwork, talking on their cell phone, or chatting with other officers. Sometimes you can see the officer walking into or out of the room. If the breath test operator is engaged in other activities and doesn't monitor the defendant carefully, then the results are not accurate or reliable.

If the officer would not notice that the subject had a polite, quite, or undetected little burp or micro-burp, then the contaminates in the oral pathway might cause an artificially inflated reading. These undetected sources of contamination need to be identified so that the 20 minute observation period can be restarted. For this reason, the officer should engage in close and continuous observation of the test subject.


Why is the 20 minute observation period before the DUI breath test required under Florida Law?

Florida's Administrative Rule 11D-8.007 requires that before the breath test is administered, the arresting officer (or another person designated for this job "shall reasonably ensure" that the person getting ready to take the breath test has "not taken anything by mouth or has not regurgitated for at least 20 minutes before administering the test."

Although continuous face to face observation is not required to comply with Rule 11D-8.007, Kaiser v. State, 609 So. 2d 768 (Fla. 2d DCA 1992), the rule requires the officer to be in a position to see and hear the person being observed for the entire period.

Florida Administrative Code 11D-8.007(3) provides:

The breath test operator, agency inspector, arresting officer, or person designated by the permit holder shall reasonably ensure that the subject has not taken anything by mouth or has not regurgitated for at least 20 minutes before administering the test. This provision shall not be construed to otherwise require an additional 20-minute observation period before the administering of a subsequent sample.

If your breath test took place at a facility with video equipment, then your attorney can order the videotape showing everything that happened from the moment you entered the room until the moment you exited the room, including the entire 20 minute observation period and during the time that you are blowing into one of the breath test machines, the Intoxilyzer 8000.

In many of these cases, the videotapes shows that neither the arresting officer nor the breath technician properly observed the Defendant for a period of 20 minutes prior to the administration of the breath test to make certain that the Defendant did not burp, belch, or regurgitate the contents of his stomach into his mouth so as to ensure an accurate breath test reading.

Certain medical conditions, such as acid reflux or GERD can also affect the arresting officer's efforts to "reasonably ensure" that regurgitation did not occur, especially when the officer was aware the person suffered from that medical condition but did not closely watch the person during the 20 minute observation period.


What if the officer was not watching me during the 20 minute period?

If the 20 minute observation period was not properly followed, then the Defendant can file a motion to suppress or exclude the test results by arguing that he was involuntarily coerced into submitting without the benefit of a search warrant, in violation of Fla. Stat. § 316.1932(1)(a) and (1)(b)2 which state that analysis of the driver's breath must have been performed in "substantial accordance" with the methods approved by the FDLE.

The burden is then passed to the prosecutor and the State of Florida to show substantial compliance with those requirements. Other attacks can be based on the Fourth and Fourteenth Amendments to the United States Constitution, Article I, Section 12 of the Florida Constitution, and the Defendant’s right to due process of law under Article I, Section 9 of the Florida Constitution and the Fifth and Fourteenth Amendments to the United States Constitution.
