1. DUI Portable Breath Test (PBT)
If stopped for suspicion of Arizona DUI, the police will ask you a series of questions. Possibly before or after requesting AZ DUI field sobriety tests (FST) the Arizona police will request to have you blow into a small hand held device on the side of the road, in an effort to continue building a case to charge you with a DUI in Arizona.

This small device is called a portable breath test (PBT). The purpose is to determine if you were drinking alcohol and supply an approximate reading of how much was in your system. This device can be used as evidence of probable cause to make an arrest for an Arizona DUI, or Arizona DWI. You can think of this one as a preliminary test. The reading on this machine cannot be used against you as evidence in court because it has not passed the necessary scientific tests to be considered an accurate alcohol concentration measuring device to meet proper AZ DUI Law testing standards. It has not been calibrated or maintained for reliability.

If the reading was 0.0 blood alcohol content (BAC) police may still suspect you of driving while drug impaired. In that event, they may continue their investigation with drug impairment testing for AZ DUI drug charges.

2. DUI Breath Test
In Arizona, the official breath test for Arizona DUI testing is done with the Intoxilyzer device. The machine analyzes the DUI suspect's breath sample without destroying it through a process of infrared spectroscopy, thereby determining the amount of ethyl alcohol present in the sample.

This machine is required to be calibrated and tested on a regular basis by the police agencies responsible for them. At times, like all machines, they have problems and may need to be taken out of service for repair or sent back to the manufacturer. It is imperative to inspect the machine records to determine if it was working properly. If a history of prior problems or defects exists with the machine, the machine and results may be invalid, and the evidence may be suppressed. In absence of machine defect or administration error, these machine results are valid and may be used as evidence against you in trial.

Top Arizona DUI defense Attorney will examine all of these elements. Your AZ DUI Lawyer should understand the factors that may affect the accuracy of the machine readings, including test protocol, temperature, and individual human body variances that may affect the outcome of your test results and your AZ DUI case. That is why it is important to select an experienced Arizona DUI lawyer who will have invalid evidence against you thrown out, and make efforts to help you avoid an Arizona DUI conviction.

Arizona DUI testing is the fourth of four major evidence categories that the state of Arizona can use against you for an Arizona DUI arrest under current Arizona DUI laws. DUI Testing includes a number of methods which will be expanded upon in greater detail in future articles:

Arizona DUI Field Sobriety Tests (FSTs)
A battery of field sobriety tests (FSTs) are given including heel-to-toe, finger-to-nose, one-leg stand, eye test called "horizontal gaze nystagmus" test, alphabet recitation, modified position of attention (Rhomberg), fingers-to-thumb, hand pat and others. In Arizona, most officers will use a set of six common tests. Arizona DUI law does not require you to take any of the Field Sobriety Tests (FSTs).

Arizona DUI Breath Test
Breath tests are used to determine the blood alcohol content (BAC) level of drivers suspected of driving drunk. Since alcohol is absorbed into the blood and blood flows through the lungs, alcohol is present in the lung's air sacs. A breathalyzer machine is used. Rather than ask drivers to submit to invasive, impractical blood or urine tests in the field, many law enforcement agency's use breath tests as a means for determining the blood alcohol level of drivers suspected of DUI in Arizona.

Arizona DUI Blood Test
Arizona DUI Blood tests are sometimes performed in order to determine the blood alcohol content (BAC) level in your system, if you are suspected of DUI. A blood test is more reliable than a breath test but may still be inaccurate due to a variety of issues. An experienced and knowledgeable Phoenix Arizona Defense Attorney will be able to investigate to determine if the blood is drawn incorrectly, if chemicals are present in the proper amount, and if the proper protocol was followed, and if not, can be challenged.

Arizona DUI Urine Test
Urine tests are typically given in DUI / DWI cases where Arizona police officers believe a driver may also be under the influence of drugs. Although urine tests are the least accurate means for measuring blood alcohol level, they are routinely used to detect the presence of illegal drugs in the body.

Again, questions arise pertaining to the accuracy of the tests, dependability of the results, and protocol that was followed. The results can then be challenged by an experienced Arizona DUI defense attorney.
