EVANSTON, Ill. (CBS) — The City of Chicago did not enact its 2-inch parking ban for the snowstorm, but in some suburbs, you could find yourself towed if you’re not careful.

In Evanston, the snow route parking ban was placed into effect Thursday night.

The City of Evanston says residents must park in accordance with the restrictions printed on red, white and blue snow route signs to allow plows to go through. Air raid sirens will sound at 8:15 p.m. to remind motorists to move their cars on nights when the city’s 2-inch parking ban is in effect.

For Thursday and Friday Evanston has also banned parking between 11 p.m. and 6 a.m. on main thoroughfares designated as snow routes.

Anyone who violates the ban is subject to a $50 fine, as well as towing and storage costs.

Parking restrictions are also in effect in neighboring Skokie. The village has enacted its alternate-side parking plan between 8 a.m. and 6 p.m. Friday, and it will be in effect for at least the next two days.

Under the plan, motorists must park their cars on the side of the street with odd-numbered addresses on odd-numbered dates, and on the side with even-numbered addresses on even-numbered dates. Odd-numbered addresses are on the south side of east-west streets, and the east side of north-south streets.

Skokie residents are advised to go to the village Web site, tune into 1660 AM Skokie radio, or call the Skokie automated snow hotline at (847) 675-SNOW. The village says some streets are exempt, and they are listed on the village Web site.
