IL CDL School Bus Test 2025
Getting ready for the School Bus portion of the IL DMV CDL skills test can seem overwhelming. You know you have to ace it to drive a school bus in Illinois, so your entire job depends on it. You have studied the Illinois CDL manual from cover to cover again, but you need to put those skills to the test to see if you have what it takes to pass. You can do just that with the IL CDL School Bus Practice Test. With questions pulled directly from the official Illinois CDL manual, this practice test has the same type of questions that you’ll find on the official exam at the DMV.
Gauge Your Knowledge
Begin by using the CDL School Bus Practice Test to gauge what you know. The 20-question multiple-choice quiz gives you the option of skipping questions that you don’t know. Skip all of the questions that you don’t know, making a note of the ones that you pass. This will allow you to assess your starting point. Then, you’ll know how much work you need to do before you go to the DMV to take your test.
After you have your starting point, hit the books once again. Study up, and once you feel like you have learned some additional information, take the practice test again. Skip the questions that you are unsure of again and then get your score. Continue to do this until you are comfortable with each question on the test.
How the Practice Test is Scored
Along with providing questions, the Illinois CDL School Bus Practice Test is scored the same way as the official test is. You can find out if you would pass the official test when you sit for the practice test.
It’s time to see how ready you are for the official exam. Find out if you’re ready to go to the DMV and get your endorsement. It all starts with the practice test.
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Triple-checked for accuracy
