FREE TX CDL General Knowledge Practice Test 3 2018

This third TX General Knowledge practice test contains another set of 50 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 General Knowledge portion of your 2018 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!
