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 20 years. His law practice is focused solely on Pennsylvania DUI defense.

Challenging the Evidence

You will need a Pennsylvania lawyer experienced in handling DUI cases who can uncover and expose mistakes and inaccuracies made by police officers. Steven Kellis is Nationally Certified in Field Sobriety Testing and has hands-on experience working with breath and blood test machines used by law enforcement agencies throughout the Commonwealth of Pennsylvania.

He understands the process of cross-examining police officers and others involved in the administration of sobriety tests and will challenge these tests if improperly given. He will photograph the arrest scene and review the police videotape of the stop, when available. This is a very important part of building a defense and requires a knowledgeable attorney devoted to DUI law. Mr. Kellis works quickly to file pretrial motions to suppress evidence, if possible, which can result in reduced penalties or dismissal of the DUI charge.


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.

Breathalyzer Test

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.

Blood Test

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.
