With colder weather and darker nights, November has traditionally been a busy time for sobriety checkpoints.  Expect this year to be no different.  While STL PD and local County departments have yet to formally announce their plans, Lake Saint Louis was the first local municipality to announce an increase in roadblocks in November.  Expect the number of municipalities declaring an increase on DUI patrol in November to increase in the coming days.  Check back here for more updates, and be safe out there.
