Massachusetts Law on DUI / OUI Checkpoints

When it comes to DUI / OUI roadblocks, aka “sobriety checkpoints”, Massachusetts law permits police to establish DUI roadblocks so long as the selection of vehicles stopped is not arbitrary and the procedure is conducted pursuant to a plan devised by law enforcement supervisors.

By way of background, a stop of a car at a police roadblock, no matter how brief, is considered to be a warrantless seizure that implications constitutional protections under the Fourth Amendment to the United States Constitution and Article 14 of the Massachusetts Declaration of Rights. The United States Supreme Court has upheld police using DUI checkpoints if they are reasonable and balance the public interest in reducing alcohol related accidents against a person’s constitutional rights.

The reason police must operate an OUI checkpoint according to a devised plan is because it is illegal for police to target which vehicles to stop. Even fixed checkpoints where police stop cars according to no set plan or pattern are illegal. In other words, if the police officers have any discretion in the stopping of vehicles, the constitutionality of the sobriety checkpoint will not be upheld.

Massachusetts courts have therefore required that, in order for police to conduct a DUI / OUI Sobriety Checkpoint, they must be governed by standard, neutral guidelines that clearly the forbid the arbitrary selection of vehicles to be initially stopped.

Once a car has been selected at the DUI checkpoint and only if the police officer has reasonable suspicion, “based upon articulable facts” that the driver may be operating under the influence, he may lawfully direct that driver to submit to a secondary screening. Courts have generally upheld further screening after the initial stop if the screening officers observed “any articulable sign of possible intoxication.”

Because challenging your OUI / DUI arrest following a sobriety checkpoint is very technical and turns on the intricacies of the drunk driving laws, you should immediately consult with an attorney who has experience in drunk driving matters.
