Local law enforcement presence will be increased Friday as the Hays Police Department will be conducting a DUI saturation patrol in an effort to deter and decrease the number of impaired and intoxicated drivers on the street. The purpose of the program is to saturate the city with roving police officers who continually monitor vehicular traffic for signs of impaired driving. Officers will place an emphasis on speeding, safety belt and alcohol-related violations. This event is being conducted in accordance with the Kansas Department of Transportation Impaired Driving Deterrence Program.
