Getting ready for the School Bus section of your MO DOR CDL skills test can seem overwhelming. You know you have to pass it in order to drive a school bus in Missouri, so your entire career depends on it. You have studied the Missouri CDL manual time and time again, but you need to put those skills to the test to see if you have got what it takes to pass. You can do just that with the MO CDL School Bus Practice Test. With questions pulled straight from the official Missouri CDL manual, the practice test has the same type of questions that you’ll find on the official test at the DOR.
Start by using the CDL School Bus Practice Test to determine what you know. The 20-question multiple-choice test gives you the option of skipping questions that you don’t know. Pass all of the questions that you don’t know, making a note of the ones that you skip. This will allow you to assess your starting point. Then, you’ll know how much studying you need to do before you go to the DOR to take your test.
After you have your starting point, hit the books once again. Study up, and once you believe you have learned some more 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 all the questions on the test.
