DUI Checkpoints in Maryland: Legal Requirements and Implications

Maryland law enforcement agencies, such as the Maryland State Police and Baltimore County Police, regularly conduct DUI checkpoints as part of their strategy to combat impaired driving. Understanding the legal framework governing these checkpoints proves essential for Maryland residents, particularly in Baltimore County and surrounding areas.

The United States Supreme Court and Maryland courts have established specific requirements for conducting constitutional DUI checkpoints. These requirements stem from the Fourth Amendment’s protection against unreasonable searches and seizures, balanced against the state’s compelling interest in preventing impaired driving.

The Tale of Two Maryland DUI Checkpoints

The Maryland Court of Appeals examined two contrasting DUI checkpoint scenarios in Little v. State that illustrate the difference between constitutional and problematic checkpoint operations. The first checkpoint demonstrated proper procedure: officers operated under detailed regulations approved by supervisors, displayed clear warning signs and flares, maintained uniformed presence, and limited stops to 30 seconds. Officers provided drivers legal options to turn around before reaching the checkpoint. The court upheld this checkpoint’s constitutionality.

The second scenario revealed multiple procedural deficiencies: officers lacked supervisory oversight, failed to display adequate warning signs, and conducted extended stops without reasonable suspicion. Such operational failures led to evidence suppression and highlighted the critical importance of proper checkpoint procedures.

Michigan’s Landmark U.S. Supreme Court Case

In Michigan Department of State Police v. Sitz, the U.S. Supreme Court established fundamental guidelines for DUI checkpoint operations nationwide. The Court examined a checkpoint averaging 25-second stops that resulted in a 1.6% arrest rate. Despite the relatively low arrest percentage, the Court determined the checkpoint served its public safety purpose through deterrence while maintaining minimal intrusion into individual rights.

Operational Standards of DUI Checkpoints

Law enforcement must provide clear advance warning through visible signage, proper illumination, and uniformed officer presence. Maryland courts mandate that checkpoint stops remain brief, typically lasting between 15 and 30 seconds unless officers observe specific indicators of impairment during the stop.

When law enforcement deviates from established procedures, significant legal consequences may follow. Evidence obtained through improperly conducted checkpoints faces potential suppression. This principle emerged clearly in Gadson v. State, where procedural violations led to evidence exclusion.
