State Police are getting a head start on their Labor Day weekend enforcement.  Troopers from the Southbury barracks will have extra patrols of the roads, concentrating their enforcement efforts on intoxicated motorists, aggressive drivers and distracted drivers.  Troopers will be conducting roving patrols tomorrow, Friday and Saturday between 7pm and 3am.  The patrols will be in the Danbury and Waterbury areas on Interstate 84 and Route 7.  If you see a suspected DUI or dangerous driver, state police are asking that you call 911 and report it to police.
