Pennsylvania DUI Attorney

A drinking and driving charge can be a confusing and stressful experience, especially if it’s your first arrest. A DUI conviction can permanently alter your life by affecting your ability to drive, your job, your future employment opportunities, and your freedom. The penalties for a DUI in Pennsylvania are potentially severe, particularly when it is not your first offense. The initial step after being charged with a DUI is to immediately contact an attorney for an evaluation. Pennsylvania DUI law is complex and requires advice from an experienced DUI lawyer who can successfully resolve your charge. Because harsh penalties can result from a drunk driving conviction, a strong defense strategy should be built for your case. It is very important to understand your rights before proceeding with the legal process.

Selecting an appropriate attorney to handle your case is vital. Due to the potential complications associated with DUI law in Pennsylvania, it’s important to have representation from an attorney who understands both sides of the law, the prosecution and the defense. Steven Kellis spent five years working with DUI cases as a Senior Assistant District Attorney and DUI Prosecutor, experience that gave him firsthand knowledge of the methods used by prosecutors and police officers in drunk driving cases. As a defense attorney, Mr. Kellis has aggressive investigation and cross-examination tactics, and has represented clients in DUI cases for more than 25 years. His law practice is focused solely on Pennsylvania DUI defense.

The prosecutor must first prove that you were “driving or in actual physical control of a moving vehicle.” This sounds basic, but you might be surprised to know that persons are regularly arrested without any evidence of driving. Mr. Kellis has handled cases involving persons asleep in their vehicle, persons arrested at their home, and even persons walking to their vehicle with their keys in hand.

The prosecutor must prove that the arresting officer had a “reasonable, articulable suspicion” for stopping or approaching the vehicle you were allegedly driving. If you were stopped at a roadblock, they must prove that the roadblock was set up and executed in accordance with the Fourth Amendment to the U.S. Constitution.

They must prove (in many cases) that you were a less safe driver as a result of drinking alcohol.

They must prove that after your arrest, the officer read the correct “Implied Consent Warning”. The correct warning must be read in substantial compliance with the statute and must be read at the time of arrest or soon thereafter as practicable.

They must prove that there was “probable cause” to arrest you for DUI. Many times they attempt to do so by presenting evidence of Field Sobriety tests. However, these tests are standardized, meaning they have to be performed systematically without deviation. That is simply not reality, since not all police officers are adequately trained on conducting these tests. The three standardized Field Sobriety Tests are listed below.

Mr. Kellis will require that the State prove each and every one of these elements on your case.

As in any criminal case, you are entitled to all police reports, transcripts, videos, audio recordings, maintenance logs, 911 CAD logs, and even information regarding the officers’ credentials, training, etc. We will obtain each and every relevant piece of evidence related to your case.

If there is a video and it is available to us, we will obtain it and review it with you prior to going to court. These recordings are very helpful in the defense of a case.

We are entitled to contest certain aspects of your case prior to a trial. Mr. Kellis regularly files and argues a variety of legal motions relevant to DUI defense. Perhaps most common is the “Motion to Suppress” evidence. Mr. Kellis will draft, file, and argue this motion where any evidence being used against you has been obtained illegally or is unreliable. Sometimes, simply filing a motion may encourage the State to reconsider or reduce your charges. Simply put, Mr. Kellis does whatever he can to win your case before you go to trial.

In the event that a trial is necessary, Mr. Kellis may suggest employing expert witnesses who can testify about the field sobriety tests or chemical tests.

The initial method for determining intoxication during the traffic stop is the field sobriety test. After the police officer pulls you over, factors such as whether or not you have alcohol on your breath, slurred speech, or red eyes and glassy eyes will be considered. If the officer suspects that you’re intoxicated, you’ll be asked to get out of the car and perform several tests, such as the one-legged stand, walk a straight line, and horizontal gaze nystagmus. The purpose of field sobriety testing is to help the officer determine if you are intoxicated or otherwise impaired and should be arrested for DUI. At least two clues of intoxication must be detected. Field sobriety tests are given at the discretion of the police officer and are considered voluntary.

The Portable Breath Test machine, commonly known as the Preliminary Breath Test or PBT, is usually given at the scene to the driver to determine if he is over the legal BAC limit of .08%. The difference between a PBT and a formal breath test is reliability. Although PBTs offer an advantage of a hand held machine in terms of mobility, these devices are far less accurate than those used at the police station or a DUI Center. Thus, a hand held PBT machine is more likely to deliver false readings than an Intoxilyzer 5000 or Datamaster Breath Test Machine. Therefore, these devices should only be used to establish probable cause for your arrest and their numeric results cannot be used as evidence against you in court. Officers are only allowed to testify that the PBT results indicated only the presence of alcohol. Unlike formal breath tests, PBTs are entirely voluntary and you are not required to blow into the PBT breath machine when you are being investigated for a PA DUI. However, if you refuse to submit to a portable breath test, you can still be taken to the police station or DUI Center for a formal breath, blood or urine test. It is important to know that, due to implied consent laws, you are required to submit to any type of formal chemical testing (such as breath, blood, or urine).

In fact, if you refuse to take a formal breath, blood or urine test, you may face more severe penalties than if you would have taken the test and failed.

The breathalyzer test, usually administered at the police station, is important evidence used against you by the prosecution. This machine measures the amount of alcohol in your blood, referred to as BAC. Since 2003, and the passage of Act 24, the illegal blood alcohol content for drivers 21 years old and over in Pennsylvania is .08 or higher. If you are under 21, you are considered to be DUI if your BAC is .02 or greater. Breath machines require maintenance and calibration, and sometimes give faulty readings. There is also the possibility of human error from the police officer administering the test. According to the National Highway Traffic Safety Administration (NHTSA) an estimated 23 percent of drivers tested with a breathalyzer will have a BAC higher than their actual blood alcohol content.

Law enforcement officers typically administer a blood test, also used to determine your BAC. For some of his clients, Attorney Kellis has discovered that the BAC was lower than the legal limit after retesting blood samples through a private lab. An expert needs to examine every detail of a DUI charge in order to provide a successful defense.
