NEW HAVEN — City police will conduct a checkpoint for motorists driving under the influence Friday night into Saturday morning, according to the department.

Capt. Anthony Duff said officers will man a checkpoint on State Street at its intersection with Wall Street. The operation is set to begin Friday at 7 p.m. and expected to conclude Saturday at 3 a.m., he said.

Under the precedent of a 1990 U.S. Supreme Court ruling in a case out of Michigan, police are required to publicize DUI checkpoint information ahead of time.

If the checkpoints aren’t publicized, it could be considered detention without reasonable suspicion — a violation of the Fourth Amendment.
