The offense of driving while intoxicated (DWI) can have severe consequences in New Jersey. Penalties can range from relatively small fines to six months in jail, along with driver’s license suspension and mandatory use of an ignition interlock device. Defending against DWI charges often involves disputing the sufficiency of the evidence, but it is also possible to challenge the legality of the entire case. If police fail to respect DWI suspects’ constitutional rights, a court could toss out the entire case. This is what happened in a case before the New Jersey Appellate Division in 2024. The case involved a police officer who suspected a driver of DWI. The court found that his suspicions were legally justified, and that the traffic stop was legal. The officer violated the suspect’s rights, however, by entering the suspects garage after she had driven her car there. This resulted in dismissal of the case.
Both the U.S. and New Jersey constitutions prohibit “unreasonable searches and seizures” and require police to get a warrant before they may search a person or their property. Courts have identified numerous exceptions to the warrant requirement. For example, police may briefly stop a vehicle on the road if they have reasonable suspicion that a driver has committed or is committing a motor vehicle offense or criminal offense. They may not hold a driver longer than is necessary to assess whether an offense had occurred or is about to occur. If they have probable cause to believe driver has committed an offense like DWI, they may continue the investigation, such as by asking them to perform field sobriety tests.
These types of stops are sometimes known as Terry stops. The name comes from the U.S. Supreme Court’s 1968 decision in Terry v. Ohio. The case established rules for traffic stops and other brief detainments by police. Generally speaking, police may not expand their search to additional locations under Terry without a warrant or another exception to the warrant requirement.
