According to the Illinois Secretary of State (SOS) moving violations such as speeding, disregarding a traffic control light, improper lane usage, etc. remain on a driver's record for four to five years from the date of conviction.

This IL state agency goes on to say if the ticket forms the basis for a suspension or revocation, the information will be carried on your driving record for a minimum of seven years from the date of reinstatement. Alcohol/drug offenses remain on a driver's record for a lifetime.

It would appear that you received this suspension due to being under the probationary period of having a license in Lithe Illinois driver's manual states that your driver’s license will be suspended if you are convicted of three traffic violations committed within any 12-month period. If you are under age 21 at the time of arrest, two traffic violations within any 24-month period will result in a suspension.

As you are likely aware if you are under age 18, you will be required to successfully complete a driver remedial education course to make your driving privileges valid again. In addition, you may be required to submit to a complete driver’s license examination to be re-issued a driver’s license. The length of the suspension varies according to the seriousness of the traffic offenses.

It would appear that it would stay on your IL driver's history for 7 years since these speeding violations led to the suspension of your driver's license. To see if this would differ due to being under the age of 21 and would come off your record sooner check with the IL SOS.

As for your insurance carrier's look back period, check with your insurance agent to see how far back they look on your driving record to determine rates. It is usually 3, 5 or 7 years depending upon the rating system of the insurance company. For consumer advice on the rating factors used in IL you can contact the Illinois Division of Insurance, the insurance regulator for the state.
