As a DUI defense attorney in Philadelphia, I’ve been asked whether DUI checkpoints are legal in Pennsylvania. Since the United States Supreme Court ruled that DUI checkpoints are constitutional, there has been a great deal of interest in these charges and whether one can get their charge dismissed on the state level if law enforcement fails to follow the requirements of a DUI checkpoint. That being said, it is important to understand that DUI checkpoints are legal within the United States and additionally, they are legal in Pennsylvania.

5 Legal Requirements for a DUI Checkpoint in Pennsylvania

In Pennsylvania, a DUI checkpoint is a well-marked, stationary roadblock conducted by the police for several hours at a time.  The officers on the scene make brief, suspicionless stops to check for driver intoxication, using a predetermined objective standard in determining which cars to stop.  Such roadblocks are advertised in advance and are situated at roadway locations where drunk driving is known to have occurred in the past.

In Pennsylvania, there are five requirements that must be met for any DUI checkpoint:

  1. The stop has to be brief and must not include a physical search;
  2. There must be sufficient warning of the checkpoint;
  3. The decision to conduct a checkpoint must have prior administrative approval;
  4. The choice of time and place for the checkpoint must be based on local experience as to where and when intoxicated drivers are likely to by driving;
  5. The decision as to which vehicles to stop must be established by administratively pre-fixed, objective and random standards, and must not be left to the discretion of the police.

If any of the requirements weren’t met at the DUI checkpoint, then any evidence obtained can be suppressed.

If an officer requests that you take a field sobriety test or a preliminary breath test (PBT) at the checkpoint, Pennsylvania law gives you the option to refuse. If the police ask you any questions other than your name, license, registration, or proof of insurance, then you have the right to politely refuse to answer. Don’t volunteer information; you can incriminate yourself by answering questions.

I recommend that you meet with a DUI defense attorney to assess what your options are. As a DUI defense attorney, I may be able to demonstrate several legal theories in which to argue your case.
