IA CDL Passenger Vehicles Marathon

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
  • Based on 2025 IA commercial driver's license manual
  • Updated for March 2025

Ready for a challenge? This Iowa CDL Passenger Vehicles Marathon is a super-challenging practice test that contains a compilation of all 118 questions that we have available for this IA endorsement. If you make a mistake, 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”. Delivers some serious studying power! Do your best to complete this mega test!
