Free OR CDL Double/Triple Trailers Practice Test 2 2025

This second OR Double/Triple Trailers practice test contains another set of 20 questions based on the official CDL manual. Just like the first test, this one is also designed to prepare you for the Double/Triple Trailers portion of your 2025 Commercial Driver’s License exam. There are three answer options, but only one of them is correct. Every time you answer a question, you’ll get immediate feedback with a detailed explanation, so you won’t need to wait until the end of the test to know the correct answers.

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
