WI CDL Pre-Trip Inspection Marathon

Fasten your seat belt for one last wild ride of studying! This Wisconsin CDL Pre-Trip Inspection Marathon is a super-challenging study tool that contains a combination of all 91 questions that we have available for this WI endorsement. If you give an incorrect answer, we’ll remember that question and will display it to you again at the end of the exam until you’ve answered that question correctly. In other words, the Marathon will cycle through your missed questions until you answer each one correctly. You must make a 100% to pass. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. Give it your best shot!

Perfect for

  • First-time WI CDL and CLP applicants
  • CDL holders adding endorsements
  • WI CDL renewal applicants
WI commercial driver's license
