The Driving Under the Influence (DUI) lawyers at the Philadelphia, PA law firm of The Zeiger Firm have many years of experience fighting DUI cases. Our attorneys have fought Driving Under the Influence (DUI) cases involving both alcohol and drugs throughout Pennsylvania. If you have been charged with driving under the influence (DUI) of alcohol or drugs, contact the Pennsylvania criminal defense attorneys at The Zeiger Firm. Our attorneys understand that driving while intoxicated (DWI) is a very serious offense, one that can affect every aspect of your life. A DUI conviction will generally result in a suspension or revocation of your driver’s license, involves possible time in jail, and may affect your employment. In addition, if you were charged with driving under the influence and were in an accident, you may be sued and your auto insurance may be canceled. That is why you need an attorney who understands all of these issues and will zealously represent you against these charges. At The Zeiger Firm, we aggressively defend persons charged with driving under the influence of alcohol and can explain your rights.
Pennsylvania DUI Law and Defense Strategy
If you are arrested for driving under the influence in Philadelphia under Title 75 of the Motor Vehicle Code, you are facing a complex legal process that involves both criminal penalties and administrative licensing actions.
- Dual Legal Challenges: A DUI arrest triggers two separate cases. The Criminal Case carries penalties like jail time, fines, and mandatory education, while PennDOT initiates an independent administrative action to suspend your driver’s license.
- The Three-Tiered Penalty System: Pennsylvania determines punishment based on your Blood Alcohol Concentration (BAC) at the time of arrest:
- Tier 1 (General Impairment): .08% to .099% BAC.
- Tier 2 (High Rate): .10% to .159% BAC.
- Tier 3 (Highest Rate): .16% BAC or higher (carries the most severe mandatory minimums).
- Graduated Sentencing: Penalties escalate significantly depending on whether the incident is a first, second, or third offense within a 10-year “look-back” period.
DUI Traffic Stops and Your 4th Amendment Rights
The 4th Amendment serves as a vital shield, preventing law enforcement from stopping or detaining individuals without cause. Understanding the legal threshold for a traffic stop is often the most critical component of a successful DUI defense.
- The Standard of “Reasonable Suspicion”: Police cannot pull you over randomly. They must have a specific, articulable reason to believe you violated a law.
- Traffic Violations: An officer doesn’t need to suspect you are drunk to pull you over; they only need to observe a minor infraction, such as a broken taillight, failing to signal, or driving without headlights at night.
- Illegal Stops: If an officer pulls you over for no particular reason in hopes of “stumbling upon” a drunk driver, the stop is unlawful and violates your constitutional rights.
- The “Fruit of the Poisonous Tree” Doctrine: If the initial stop is proven illegal, the evidence that follows is generally inadmissible.
- Evidence Suppression: If your attorney proves there was no reasonable suspicion for the stop, all subsequent evidence—including the smell of alcohol, failed field sobriety tests, and BAC breathalyzer results—can be suppressed.
- Case Dismissal: Without that evidence, the prosecutor typically loses their ability to prove the case, often leading to an outright dismissal of the charges.
- Challenging the Officer’s Narrative: It is common for officers to attempt to justify an unlawful stop after the fact by claiming a minor “phantom” swerve or equipment issue. An experienced attorney can identify these inconsistencies and hold law enforcement accountable.
Pennsylvania Implied Consent Law
Many people believe that if they are stopped and suspected of driving under the influence, they can simply refuse to participate in a breath test and there will be no evidence of their BAC. However, it is important to realize that there are consequences for refusing a breath test in Pennsylvania.
Pennsylvania has an implied consent law, which means that if you are licensed and you drive in Pennsylvania, you have impliedly consented to submit to a breath, blood, or urine test if you are lawfully detained by an officer who has probable cause to believe that you are impaired. An officer must observe you for at least 20 minutes before performing a breath test, though any chemical tests must be completed within two hours of the time you were last driving.
If an officer lawfully requests that you submit a breath, blood, or urine sample, you should know that there are specified consequences if you refuse. An officer should warn you of these consequences at the time of their request. Specifically, your driver’s license will be suspended for a period of time based on your refusal – even if you are not later convicted of DUI.
The following are the license suspension periods in Pennsylvania for refusal to blow:
- First offense = One year
- Second or subsequent offense = 18 months
- Refusal with a previous DUI conviction = 18 months
You will have a hearing based on your refusal to submit to a breath test. At this time, you may be able to receive limited driving privileges – such as to attend work or school – if you agree to have an ignition interlock device installed on your car. Still, this can be inconvenient and costly and will be in addition to any consequences if you are convicted of DUI.
Refusing a breath test does not mean that you cannot be convicted of drunk driving. A BAC reading is a major piece of evidence in many DUI cases but it is not the only evidence used by prosecutors. Without chemical test results, prosecutors can still use the officer’s testimony that they witnessed signs of intoxication during the traffic stop.
Such observations can include:
- Stumbling
- Slurring of words
- Watery or bloodshot eyes
- Disorientation
- Smell of alcohol
- Open containers in the vehicle
Much weight can be given to an officer’s observations even without a breath test showing you were over the legal limit. A refusal can then mean that you face the penalties for both a DUI and for refusing to participate in the test.
If you refused to take a chemical test, you need a defense lawyer who knows how to handle this part of your case in addition to your actual DUI charges. The Zeiger Firm can represent you in all aspects of your DUI case and all related charges.
Challenging Chemical Tests
If you do agree to a breath or blood test and the test reports that your BAC is over the legal limit of 0.08%, it does not necessarily mean that you will automatically be convicted of driving under the influence of alcohol. While a chemical test does create the legal presumption that you are intoxicated, these tests are not infallible. There are different ways that a skilled defense lawyer can determine whether the test results were inaccurate for some reason.
The following are some examples of reasons why a breath or blood test may be unreliable:
- Officer error – There are specific procedures that law enforcement officers must follow to ensure the accuracy of chemical test results. For example, as mentioned above, they must conduct a test after 20 minutes of observation and within two hours of you driving your car. If the officer conducts a breath test too early, the test may measure mouth alcohol, which can significantly increase BAC results. If an officer waits too long, the test will not give an accurate representation of your state while you were driving. If an officer mishandles equipment or does not conduct the test properly, it can result in a false positive result.
- Equipment error – Equipment used for breath tests must be regularly maintained and calibrated in order to give an accurate reading of your blood alcohol content. If a breathalyzer is not calibrated correctly or is otherwise defective, the reading will not be reliable. An experienced attorney can look at law enforcement records to determine whether a piece of equipment has been calibrated or not.
- Forensic lab error – When you give a blood sample for a BAC reading, that sample must be processed by forensic lab technicians. There are many errors that forensic labs can make that can render a test result unreliable. For example:
- Storing a blood sample at the wrong temperature
- Allowing a sample to become contaminated
- Incorrectly labeling a sample
- Mixing up samples
- Allowing unqualified people to handle the sample
- Waiting too long to test the sample
- Not properly recording test results
- Using equipment that is defective or not calibrated to test the sample
Even if a sample is properly tested, there is still a margin of error in every type of scientific testing. If your BAC reading is close to 0.08%, the margin of error may mean that it is possible your BAC was truly under the legal limit. Your attorney can argue against the presumption of impairment in such cases.
Law enforcement departments should always be held accountable if they made errors during DUI testing. Our legal team will explore the possibility that your chemical test results may be inaccurate and will use it in your defense strategy whenever possible.
Other DUI Defenses
Arguing that your traffic stop was unlawful or that a chemical test result is inaccurate are only two ways to defend against a DUI charge. Some other common defenses can include:
- Medical issues – There are numerous medical or physical conditions that can not only give the false appearance of intoxication but can also result in false BAC readings. Acid reflux can cause mouth alcohol, which can cause an inflated BAC reading. Kidney problems can also lead to an increased BAC result. Ketosis – which is common among people with diabetes or who follow a strict low-carb diet – causes glucose to ferment in the bloodstream, which can both an odor similar to alcohol on the breath, as well as a false BAC result. Neurological conditions and brain injuries can cause slurred speech and the appearance of disorientation, as can fatigue. Allergies or similar issues can cause bloodshot or watery eyes. These are only some examples of medical conditions that may be presented in a DUI defense to combat the allegation that you were under the influence of alcohol.
- Improper communications by authorities – After an arrest, police officers are required by law to inform a defendant of their Miranda rights, which include the right to remain silent and the right to be represented by an attorney. If a defendant invokes these rights, police are not allowed to try to interrogate an arrestee until an attorney is present. If an officer does question someone in violation of their Miranda rights, a defense attorney can argue that any answers or confessions to being intoxicated should be thrown out of court. If an officer does not properly inform someone of their Miranda rights, any information gathered after an arrest should also be kept out of evidence. In addition, prosecutors often try to get a defendant to plead guilty without the presence of their defense counsel. They have many tactics they can use to convince a defendant to agree to a guilty plea that would not be allowed by a defense attorney. Such guilty pleas may be set aside so you have a chance to truly defend against your DUI charges.
- Challenging officer testimony – In order to use an officer’s observations as evidence, a prosecutor must put the arresting officer on the stand and have them attest to the events of the traffic stop and the arrest. Often, police officers make multiple DUI arrests each week and the details of each stop can run together. If an officer cannot correctly testify as to what happened during your traffic stop or their observations, this is unreliable evidence. A defense attorney can cross-examine police officers to identify any inconsistencies in their testimony or any gaps in their memory that can cast doubt on their testimony.

Strategies for Avoiding a DUI Conviction in Philadelphia
Because penalties escalate significantly with each subsequent offense, the primary goal of a defense strategy is to prevent a conviction from ever entering your permanent record.
- Identifying Constitutional and Procedural Errors: Our first step is a meticulous review of law enforcement’s actions. We look for 4th Amendment violations, improper breathalyzer calibration, or failure to follow field sobriety test protocols, any of which can lead to a case dismissal.
- Pre-Trial Diversion Programs (ARD): If the evidence is strong, we investigate your eligibility for diversionary programs like Accelerated Rehabilitative Disposition (ARD).
- The Benefit: If you complete the court-ordered requirements (similar to probation), the charges are dismissed and the arrest can often be expunged.
- Availability: This is a common and highly effective route for many first-time DUI offenders in Pennsylvania.
- Negotiating Favorable Plea Agreements: When a dismissal isn’t an option, we negotiate with prosecutors to minimize the long-term impact. This may include seeking a suspended sentence, allowing you to avoid a formal conviction upon the successful completion of probation.
- Aggressive Trial Representation: If you have been wrongfully accused, we provide a robust defense at trial. Criminal trials are governed by strict procedures and rules of evidence; we ensure the prosecution meets their burden of proof while aggressively challenging any evidence that fails to meet legal standards.
- Holding the Prosecution Accountable: A skilled trial attorney knows how to identify when a prosecutor violates procedural rules and will lodge proper objections to protect your rights before a judge or jury.
