Massachusetts DUI roadblocks are likely to increase in light of campaigns by law enforcement to curb drunk driving by putting more police officers on patrol and increasing the number of DUI roadblocks. One issue that may arise in Massachusetts is whether a police officer can stop a motorist under the Fourth Amendment when the driver lawfully attempts to avoid a DUI roadblock.

This issue arose in a case decided by the New Mexico Supreme Court on August 25, 2009 in the case of State v. Anaya. In that case, the New Mexico Court of Appeals affirmed a trial judge who held that the police officer had no reasonable suspicion to stop a driver who lawfully made a u-turn prior to a DUI roadblock. As a result of the motion to suppress being granted, the DUI lawyer suppressed all evidence gathered as a result of the stop, including observations of the officer and results of field sobriety tests.

The State appealed from the trial judge's ruling. The Court of Appeals affirmed and the State appealed to the New Mexico Supreme Court, which reversed the lower courts. Under the Fourth Amendment to the United States Constitution, police officers need reasonable suspicion to stop a motorist. This requires that the officer have a specific basis for believing that the motorist committing a traffic infraction or violated the criminal laws in some fashion. The Fourth Amendment prohibits a police officer from detaining a driver based on what the law refers to as a mere hunch.

The New Mexico Supreme Court's decision is inconsistent with clearly established Fourth Amendment case law. The court holds that the roadblock begins when the motorists could first become aware of its presence. According to the court, the roadblock starts when it is in sight of the motorist which would greatly expand the scope of the roadblock. The court attempts to limit its ruling by stating that not all case of avoiding a roadblock will constitute reasonable suspicion, depending on the time of day, proximity to the roadblock and traffic patterns.

However, in Anaya, the motorist made a legal u-turn. Nothing other than the officer's speculation could support a basis to stop the motorist which is insufficient to provide a constitutional justification for the police to seize an individual.

If this issue were to arise in a Massachusetts drunk driving case, the Massachusetts courts would be unlikely to follow the New Mexico Supreme Court in light of other case law by the Massachusetts courts interpreting the Fourth Amendment and State Constitution.
