Tempe AZ DUI Charges

If you were stopped and suspected of a DUI in Tempe AZ, after questioning and some field sobriety testing, the police may have requested that you take a breath test with a Portable Breath Test (PBT) unit. If your Arizona DUI charges were based on the results of the PBT results alone, it can not be used as evidence against you. This scenario gives an experienced Arizona DUI Attorney a strong defense on your behalf that may lead to a dismissal of your Tempe DUI charges.

Portable Breath Testing Device (PBT)
The Preliminary breath test (PBT), often called a portable breath test device, refers to the hand-held breath testing instrument used at the side of the road. This takes place prior to an arrest. The purpose of the PBT is to determination an alcohol concentration levels in your system, otherwise called the blood alcohol content (BAC). The primary purpose of the PBT is for preliminarily testing only. The results will give the Arizona police officer an idea of whether or not there is alcohol in your system if they suspect you of Arizona drunk driving or being "impaired to the slightest degree" while driving in Arizona. If the results are positive for any alcohol in your system, they will proceed to the second official breath test. The second test results from the official machine can be used against you in court, but not the PBT.

If your PBT results were "0" or negative, but the officer stills suspects you of driving impaired based on other "cues", they will move to determine if they are dealing with an impaired driver due to DUI with prescription drugs, DUI with illegal drugs, DUI with Marijuana, DUI with toxic substances or DUI with other chemicals.

The results of the PBT unit are not admissible as incriminating "evidence" to prove that the person has a certain measurement of alcohol present in their body. This is due to the fact that the PBT unit is scientifically unreliability. Therefore, the digital results of the PBT are only useful to the police to help them determine whether or not to they are dealing a driver who may be impaired by alcohol or drugs, and how to proceed with the next step of investigation.

The Official Breath Test
In Tempe AZ, the official breath testing is currently performed and evidence recognized with a machine some call the "Intoxilyzer 8000 Device".
This machine is required be calibrated and tested and routinely maintained on a regular basis by the Tempe police agencies responsible for them. Repair and maintenance records must be kept for all maintenance and repairs. It is not unusual for a breath machine to have a problem and to be pulled out of service for repair. Sometimes, the breath machine has to be sent back to the manufacturer for service or repairs. The only way to determine if the machine was working properly is to view its service records from before and after the arrest.

Breath testing provides instantaneous results, but there is controversy in the scientific community over the accuracy of breath testing and these machines in particular. Many factors can affect the accuracy of the readings of these machines including proper operator error, testing procedure, temperature, and individual human body variances.
