The Fourth Amendment’s prohibition on unreasonable searches and seizures means that police officers cannot stop a person while driving without reasonable suspicion of an offense, and they cannot search or arrest someone without probable cause. A person charged with driving while intoxicated (DWI) and other offenses also has the right to confront their accuser, usually the arresting officer, under the Sixth Amendment’s Confrontation Clause. A DWI defendant recently appealed the denial of her motion to suppress in State v. Ciernak, challenging the sufficiency of the evidence leading to her traffic stop. She further argued that the officer lacked justification to stop her under the “community caretaking function,” an exception to the Fourth Amendment’s search-and-seizure provisions.

Court decisions at the state and federal levels have held that field sobriety tests and breath tests in DWI cases require probable cause, such as if an officer detects an odor of alcohol or other indicators of intoxication, if they observe the vehicle driving erratically, or if the driver admits to consuming alcohol. This standard is lessened, however, under the “community caretaking function,” which holds that police are permitted to stop vehicles in the absence of suspicion of any specific traffic or criminal offense, if they reasonably believe there is a danger to public safety.

The U.S. Supreme Court articulated the elements of the community caretaking function in 1973 in Cady v. Dombrowski, which involved the search of a vehicle involved in a traffic accident. The search yielded illegal firearms, and the court upheld the constitutionality of the search. The New Jersey Appellate Division has affirmed the community caretaking function in situations like driving slowly on the shoulder of a highway with the left turn signal activated for approximately one-tenth of a mile (State v. Goetaski, 1986), and remaining stopped at a green traffic light for 23 seconds (State v. Hancock, 2014). The New Jersey Supreme Court, however, held that the community caretaking function does not justify entering a person’s home without consent to conduct a welfare check without “an objectively reasonable basis to believe that there is an emergency” (State v. Vargas, 2013).

The Fourth Amendment to the U.S. Constitution protects people from “unreasonable searches and seizures” by law enforcement. It requires police, in order to obtain a search warrant, to demonstrate “probable cause” to believe that the search will yield evidence of criminal activity. U.S. courts have identified various exceptions to the warrant requirement, but it remains a powerful safeguard of people’s rights. The New Jersey Superior Court, Appellate Division recently considered a DWI defendant’s argument that her admission to drinking alcohol during a lawful traffic stop did not provide enough probable cause to justify breath testing or field sobriety testing. The court rejected this argument in State v. Dunn, finding that her voluntary admission was enough to establish probable cause.

Courts have identified numerous exceptions to the Fourth Amendment’s warrant requirement. The “automobile exception,” for example, holds that cars and other motor vehicles may be subject to stops and limited searches without a warrant. The primary rationale for this exception is that any evidence a vehicle might contain is at risk of disappearing. This has an obvious bearing on DWI cases, many or most of which begin with a traffic stop.

The Supreme Court has held that police may stop a person and conduct a basic search, even without enough probable cause to support a warrant, if they have a reasonable suspicion that the person is in the process of committing, has recently committed, or is about to commit an offense. This is known as a “Terry stop,” after the Supreme Court’s 1968 decision in Terry v. Ohio. It applies both to in-person stops, often known as “stop and frisks,” and to traffic stops.
