What court case addressed the legality of roadblocks aimed at identifying DWI offenders?

The case that specifically addressed the legality of roadblocks aimed at identifying DWI offenders is Las Cruces v. Betancourt. This ruling evaluated the balance between the state's interest in removing impaired drivers from the roads and the Fourth Amendment rights of individuals against unreasonable searches and seizures. In this context, the court upheld the use of checkpoints for DWI enforcement, establishing that if conducted properly, these roadblocks can be viewed as a reasonable method for promoting public safety without violating constitutional protections.

Focusing on the other choices, State v. Ortega primarily dealt with the sufficiency of evidence in a drug-related case, not roadblocks. Arizona v. Gant is about searches of vehicles following an arrest, which does not pertain to roadblocks for DWI. Similarly, Miranda v. Arizona centers on the rights of suspects in custody, specifically the requirement to inform them of their rights, and does not involve roadblock legality. Thus, Las Cruces v. Betancourt stands out as the key case relating to DWI checkpoints and their constitutionality.
