A Massachusetts sobriety checkpoint now routinely produces a complete audio and video record of a driver’s roadside encounter, captured on troopers’ body-worn cameras. The Supreme Judicial Court addressed that kind of recording for the first time in a decision issued June 2, 2026, holding that footage from a State Police checkpoint can be used as evidence in an operating under the influence prosecution. For a driver facing an OUI charge in Boston or elsewhere in Suffolk County, the ruling shapes both what the Commonwealth can show a jury and where the defense can still push back.
The recordings are admissible because the troopers did not secretly record the driver. The Court reasoned that a large, reflective sign warning of recording at the checkpoint, combined with body-worn cameras worn openly at chest level with visible red lights, meant there was no willful interception under the Massachusetts wiretap statute. That holding does not hand the prosecution an automatic conviction. Video of field sobriety testing often helps the defense as much as the Commonwealth, and Attorney Patrick J. Murphy has spent more than three decades defending OUI cases in Boston and across Suffolk County by holding the Commonwealth to every element it must prove.
