    (*) IF YOU HAVEN’T RECEIVED YOUR PERMIT THAT WAS ORDERED ONLINE – Please read the following… The first thing you need to do if you haven’t received your permit is check the status of the permit online (you will need your reference # to do this). The best way to check on your permit status is as follows:

    1. Get back on the internet website (https://truckpermits.dot.illinois.gov/).
    2. Check the box in front of I have read Form OPER 993 and agree to the provisions stated therein
    3. Enter in your form of payment that you used when you originally placed your order (either your Account & Pin Number or credit card and expiration date).
    4. This will open up the Permitting System Menu – right under the heading Permitting System Menu reads Click HERE for PERMIT STATUS INFORMATION - Please click on this line
    5. This will open a Permit Information Box – please enter your reference number in the box and click Submit
    6. This will open up one of the following several statements telling you where your permit is in our system:
      1. UnProcessed Bin! – Means your application has been received and is currently waiting to be processed
      2. In Public Contact Bin! – Means your application has been received and while being processed an error or question was discovered. The problem will be stated below and you can respond directly back to the permit writers from that screen.
      3. Permits Sent to District/Bridge Office Bin! – Means your application has been received and due to the size of your load it was sent to for a District Investigation (if over 16’Wide or over 17’ High) or for a Bridge Investigation (If over 230,000 lbs or if the route requested is not cleared for your weights). These investigations take several days (7-10 full working days for a District Investigation and 3-5 full working days for a Bridge Investigation and the day it was sent over does not count as a full working day). PLEASE NOTE: THIS IS A SUPERLOAD ONLY RESPONSE.
      4. In Checker Bin! – Means your application has been received and processed and is currently being double-checked by a checker. If there are no problems it will be checked and sent out to you.

If you have not received the permit or realize your fax number was entered wrong you can click on the link to have it refaxed. You will need your reference number or permit number to do this. If your fax number was entered wrong you will be able to change the number it is being faxed to as well. If you get a message telling you it cannot be faxed because it is in “H” status you will need to call 217-785-1477 option 4 to change the permit to “A” status and fax it to you.
      6. Insufficient Funds! – Means that your permit has been processed, however, when it was being uploaded there was currently not enough money in your account to pay for the permit. It will also give you an option to change the form of payment at this time to a credit card. PLEASE NOTE:  Once you have changed the form of payment to a credit card you must use that credit card number to check the status of the permit. It will no longer be listed under your account number.

    Once you have checked the status online and if you have any further questions please contact us at 217-785-1477 option 4.

  2. Click the Tools tab
  3. Click Internet Options (this opens a gray box with several tabs across the top)
  4. Make sure the General tab is open (in the middle of the page you will see a Temporary Internet Section)

  • HOW LONG WILL IT TAKE TO GET MY PERMIT?
    WE CANNOT PUT A TIME FRAME ON ANY PERMITS ISSUED BY THE PERMIT OFFICE DUE TO TOO MANY VARIABLES (i.e. the number of permits coming being ordered, the number of writers working that day, the difficulty of the permits, any problems or questions on your permit, additional specific requirements (i.e. requires bridge analysis or district investigations)).
    • Routine permits
      If you have not received a routine permit within 30 minutes of receiving a reference number you need to check the status of your permit and see if there is a question that needs to be answered.
    • Super Load permits
      Check the status of your permit often to see where your permit is. The computer will tell you exactly where you permit is (unprocessed bin, checker bin, sent to Districts/Bridges, public contact (if there is a question that needs to be answered before permit can be processed, or on the main frame). Please do not call to check the status of the permit as our public contact people will only tell you the same thing that the computer does.
