The Knowledge Examination has Two Parts
The Illinois exam consists of two parts.
The first part (this test) has 15 questions asking about common traffic signs described in Rules of the Road .
The remaining 20 questions will be multiple-choice or true-false questions about Illinois traffic laws and safe driving.
This Illinois traffic sign identification practice test helps you ensure you have learned all the road signs, including the use of shapes and colors.
It is a randomized practice test that pulls questions from a larger pool of questions, which means that each time you take the test, it will look slightly different and have new questions.
