Example: A vehicle from Illinois has their last digit being a 3. Thus under the rules above from Monday to Friday, they cannot drive between 5 a.m. to 11 a.m. However, on Wednesday, they have the additional restriction that they cannot drive between 5 a.m. to 10 p.m. And on the third Saturday of the month they cannot circulate between 5 a.m. to 10 p.m. The only way they can get around this is to obtain a 0 or 00 sticker should their vehicle be 8 years old or newer.
