DuPage County, IL Parking Rules: Street Parking Limits (2026)

' The rule applies around the clock, not just during rush hour or snow events, and covers every County highway, meaning the roads the County itself maintains rather than municipal or state routes. Subsection (B) makes a violation a misdemeanor, punishable by a fine of not less than $10 and not more than $200 for each offense, so a vehicle left blocking a County road for several days can generate a separate fine for each day it remains. The rule sits within Article II of Chapter 23, alongside § 23-16, which separately restricts parking within the County government complex itself and lets the County tow any vehicle from a restricted complex lot at the owner's expense, and § 23-18, which lets the County Engineer close a County highway to heavy trucks over 20,000 pounds for up to 90 days a year when road conditions require it.

Chapter 23's general vehicle-code provisions, adopted by reference from the Illinois Vehicle Code under § 23-3-1, apply to parking violations not specifically addressed here, but § 23-17 itself sets its own $10-$200 fine range rather than deferring to the Vehicle Code penalty tiers in § 23-3-2.
