CA CDL Combination Vehicles Marathon

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

Fasten your seat belt for one last wild ride of studying! This California CDL Combination Vehicles Marathon is a gargantuan study tool that contains a mix of all 158 questions that we have available for this CA endorsement. If you make a mistake, we’ll remember that question and will display it to you again at the very end of the Marathon 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”. Good luck!
