This fifth CA Double/Triple Trailers practice test contains another set of 21 multiple-choice questions based on the official CDL manual. Just like our other practice tests, this one is also designed to prepare you for the Double/Triple Trailers portion of your 2025 Commercial Driver’s License exam. There are several answer options, but only one of them is correct. Each question also includes a hint and an explanation. It is recommended that you check each question’s explanation to gain some further insight into the rule being tested. 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. Good luck and drive safely!
