I received my 2nd speeding within 3 months of each other, will I still be able to take the internet traffic course?

It is not possible to predict what the outcome will be.

Good luck.

That will depend on the Judge. You are not eligible to apply for traffic school by mail, and must request a court date if you want any form of supervision, including supervision with traffic safety school. As a general matter, I wonder why anyone would make traffic safety school their objective when facing a traffic ticket in Illinois. Why hope for less than the best possible result? I always recommend requesting a trial date, then retaining experienced counsel to give you the best opportunity for a favorable result. Several results far better than traffic school are possible with competent representation.
