Fighting a DUI in Allegheny County and elsewhere in the Commonwealth of Pennsylvania requires very specific knowledge, training and experience. A defense attorney should be able to demonstrate with confidence that she/he knows how to beat a DUI based on past cases and experience in drunk driving defenses, which include:

Probable Cause Defenses
Field Sobriety Defenses
Blood Test Defenses
Breathalyzer Defenses
Unlawful Stop Defense and
Suppression of Evidence
DUI Defense Strategies In PA
Probable Cause means that police have sufficient grounds to suspect operation of, or control over a vehicle while under the influence of drugs or alcohol before arresting you and requiring chemical testing. Unfortunately, police are not required under PA law to tell you that you have the right to refuse, without consequence, all field sobriety tests, including the portable (roadside) breath test (PBT). These tests are used to develop probable cause for a DUI arrest.

If police did not develop sufficient grounds to arrest you for a DUI, then your attorney can ask the court to have all subsequent chemical tests after your arrest suppressed from evidence.

An Unlawful Stop by law enforcement happens when police have no reason allowed by law to stop you for investigation. Under the Vehicle Code, an officer can stop a vehicle and pursue further investigation (such as for DUI) if a violation of the Vehicle Code has occurred, or is reasonably suspected.

If the defense can show that no violation existed, or that there was no reason to suspect one, charges may be dismissed. Police also need to have proper jurisdiction over you in order to make a lawful stop. There are many other defenses to a DUI charge.

The Standardized Field Sobriety Tests that can be used to obtain probable cause for arrest officially recognized under Pennsylvania law are: the Horizontal Gaze Nystagmus test, the Walk-and-Turn test, and the One-Leg Stand test. If any other tests were used to develop probable cause for your arrest, then your criminal defense attorney may be able to have the chemical test results suppressed. Even if you submitted to the standard field tests, there can be a number of errors argued in order to suppress blood alcohol content (BAC) evidence or breath test evidence.

Blood testing for BAC determination is subject to numerous flaws. If blood testing machines are not maintained and calibrated properly, errors occur that can result in significantly higher BAC rates for the samples tested. For example, a recent Pennsylvania court ruling determined that a crimes lab used improper procedures for blood sample testing that compromised all samples tested for DUI cases. The case demonstrated that blood testing labs may not use the amount of blood required under the law for proper BAC testing. There are many things that can be challenged in a blood test DUI case. The police, health care workers and all lab personnel have to follow the proper procedure to collect and test your blood and there are many opportunities for mistakes. Only a highly trained DUI attorney can identify these mistakes and use them to your advantage to fight your DUI.

Further, your blood test may be shown legally insufficient if the lab used enzyme tracers instead of gas chromatography methods. In addition, if you requested separate blood samples so your BAC could be independently tested, and police refused that request or your request was unmet, your defense attorney may move to have the BAC results from the county suppressed from evidence.

A Breathalyzer Defense can be effectively used in 2 common situations. If you were pulled over by police and asked to take a preliminary breath test –or PBT, then you were handed a portable device that is often used in field sobriety testing. This portable device is not always accurate or properly used by law enforcement. If your PBT results were the basis for your DUI probable cause and arrest, then your defense may lie in discrediting the PBT.

Also, if you submitted to a Breath Test administered at the station that used a much larger breath testing machine, then you may have several defense options to challenge your BAC results. For example, the manufacturer of the most widely used breathalyzers in PA has recently been discredited by a Dauphin County Judge. The Judge cited lack of calibrations and independently certified sample solutions during manufacture as key reasons that the breath machine results may be faulty.

Moreover, experienced DUI forensics experts have argued that statistical sampling from any breathalyzer device lacks clear and indisputable results. For example, newer models take ‘samples’ from your deep lung airways. Yet, if the machine was not properly maintained and calibrated, then a common “mouth-alcohol” sample can occur. Numerous elements can wrongly elevate the machine’s readout in these instances, such as antiseptics (mouth washes & breath fresheners), energy drinks, even bread. You may also have a defense if you suffer from Acid Reflux Disease.What You Can Do
Write down everything that happened as soon as possible. Note the arresting officers’ names and station. Write down the names and addresses of all witnesses; including any other passengers. Recall all the field tests you took, and whether anything seemed off to you about these experiences. You will need to recall and write down everything you had to eat and drink within at least 12 hours of your arrest. Write down any medication taken in the 24 hours before the DUI, whether prescription or over the counter.

Where were you? What time was it when you were first stopped and investigated? What was said between you and the officer(s)? What chemical test(s), if any, did you submit to, and where was it administered? What time was the BAC test given to you? Who was the test administered by, and what exactly did that person do during the procedure?

Details like how many times you were asked to blow into the breathalyzer, whether you were constantly monitored by the test-giver; or what kind of swab was used prior to the blood draw (alcohol, iodine, etc.) may be helpful to your defense. If you submitted to a urine test, was your bladder properly emptied beforehand? Was a breathalyzer used, and if so, what did it look like?

Finally, bring all of your notes to an experienced and well-qualified DUI defense attorney IMMEDIATELY. Regardless of what police may have told you, the single most important step you can take to fight against any DUI is to work with a criminal defense attorney who is specifically trained to help you.
