Driving in the city of Chicago, downtown area is not recommended. Rush hour traffic and one-way street systems can leave you thoroughly confused. High parking rates are another negative aspect of driving. Major attractions have their own limited parking lot but parking in Downtown is pretty expensive. During winter months (1 Dec to 1 April), snow parking regulations are applicable which leaves less parking space. Cars parked on snow routes are likely to be towed away. It's much easier to use the public transportation system, the free trolley rides, and of course traveling by foot wherever possible. If you do choose to get behind the wheel, remember that Chicago is laid out in a very straight forward grid pattern, which makes it easy to follow directions. Unless otherwise posted, a right turn on red is allowed after stopping and signaling.
