SB 3374

Amends the Illinois Vehicle Code. With regard to automated speed enforcement systems in safety zones, provides that "safety zone"" does not include any roadway in which the 30 mile per hour speed limit is decreased by local ordinance without an engineering or traffic investigation. Provides that a local authority or park district shall determine and declare by ordinance a reasonable and safe absolute maximum speed which: decreases the limit within an urban district which shall not require an engineering or traffic investigation to a maximum speed limit of 25 miles per hour, but not less than 20 miles per hour and a maximum speed limit of 10 miles per hour in an alley; increases the limit within an urban district, but not to more than 55 miles per hour, if after increasing the limit within an urban district an engineering or traffic investigation is required to decrease the limit; or decreases the limit within a residence district which shall not require an engineering or traffic investigation to a maximum speed limit of 20 (rather than not to less than 25) miles per hour. Requires a park district, city, village, incorporated town, or county board to post a sign designating the new speed limit. Makes other changes."
