Pennsylvania Court Discusses Timing of Blood Draws in DUI Cases

A blood test can shape a DUI prosecution, but a later change in search-and-seizure law does not automatically make earlier plea advice ineffective. In a recent Pennsylvania decision, a defendant sought post-conviction relief after pleading guilty to charges arising from a serious crash. The dispute centered on whether counsel should have recommended a motion to suppress blood-alcohol evidence. The ruling highlights why the timing of a plea and the source of a hospital blood draw matter. If you face DUI charges in Pennsylvania, speak with a knowledgeable Pennsylvania DUI defense attorney before deciding whether to challenge evidence or accept a plea.

Facts and Procedural History

Reportedly, in June 2021, the defendant drove into oncoming traffic in Chester County and struck another vehicle head-on. Witnesses observed signs of intoxication, and the other driver sustained severe injuries. Testing of the defendant’s blood showed a blood-alcohol concentration of 0.258 percent. The defendant’s license was suspended because of a prior DUI conviction, and the vehicle lacked required insurance.

It is alleged that, after arrest, the defendant submitted a suppression motion without counsel, challenging the warrantless blood draw. Because counsel represented the defendant, the court did not act on that filing. In December 2022, the defendant instead pleaded guilty to DUI, aggravated assault by vehicle while DUI, and related licensing, accident, and insurance offenses. The negotiated sentence included five to ten years in prison followed by five years of probation.

Allegedly, the defendant timely sought relief under Pennsylvania’s Post Conviction Relief Act in January 2024, claiming plea counsel had inadequately explained a possible suppression challenge. At a two-part hearing, a detective testified that hospital staff drew blood as part of a treatment protocol and that he asked the hospital to preserve it while he obtained a warrant. Another officer’s incident report suggested the detective had requested the draw, but the detective disputed that account. Plea counsel testified that he had discussed suppression and warned that an unsuccessful motion could cost the defendant the plea offer. The trial court denied relief in October 2025, and the defendant appealed.

Timing of Blood Draws in DUI Cases

On appeal, the defendant argued that police directed the hospital to draw blood without a warrant and that a later warrant for testing could not cure the initial seizure. The court accepted the trial court’s finding that the detective had not ordered the draw. It also distinguished the law governing the 2022 plea from two 2025 decisions. Those later decisions invalidated a statute authorizing certain warrantless hospital draws and emphasized the need to determine whether a hospital acted for independent medical reasons or under that statute. The court did not decide whether a suppression motion filed under today’s law would succeed.

Instead, the court held that the defendant had not shown the proposed motion would have succeeded when the plea occurred. The relevant statute had not yet been invalidated, the detective obtained a warrant before acquiring and testing the blood, and the defendant supplied no evidence disproving a medical or then-authorized basis for the draw. Because counsel could not be faulted for failing to anticipate the 2025 rulings, the court affirmed the denial of relief.
