Drivers will be checked for impairment at the intersection of Northeast 11st Street and First Avenue from 8 p.m. Friday to 1 a.m. Saturday, according to a Miami Police news release.
So if they want to catch drunken drivers, why announce where the checkpoint will be?
Florida is one of 39 states, plus Washington, D.C., that allow police agencies to set up DUI checkpoints. In several of those states -- Florida included -- police have to announce ahead of time when and where they will conduct sobriety checks.
Here's more information about the Florida Sustained DUI Enforcement Program and here is a .PDF document from the federal highway administration that explains some rules and statistics concerning sobriety checkpoints and patrols.
