CHICAGO (CBS) — This is your last chance to buy a Chicago city sticker if you want to avoid a ticket.

As WBBM Newsradio 780’s Bob Roberts reports, the old stickers expired June 30, but the city gave motorists a two-week grace period. That period comes to an end on Friday.

Beginning Saturday, those lacking new stickers face a $120 ticket if caught by police. Even those who are not will face a $40 penalty fee for buying a sticker late.

Prices for stickers remain unchanged from last year.

Stickers are $120 for large sport-utility vehicles, and $75 for other autos. Senior citizens can obtain one sticker for $30.

Residential parking stickers cost an additional $25 and daily guest passes are $8 for 15 passes.

Stickers can be purchased at the city Clerk’s Office and Chicago Department of Revenue offices, as well as Dominick’s grocery stores and currency exchanges.

To purchase a sticker in person, you must bring your driver’s license or renewal form, and supply your license plate number.

The city issues 1.3 million vehicle stickers and residential parking permits each year.
