CT CDL General Knowledge Exam Simulator 2025

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

To become a commercial driver in Connecticut, you must obtain a Commercial Driver’s License (CDL). You must be at least 18 to drive within the state and 21 to drive commercial vehicles across the nation, carry hazardous materials, or transport passengers. The DMV requires all applicants to pay the necessary fees, provide proof of residency, pass a medical exam, and pass several knowledge tests. The general knowledge exam consists of 50 multiple-choice questions based on the official Connecticut commercial driver license manual (Connecticut CDL Handbook 2025). Additionally, you may have to pass separate knowledge tests for certain endorsements and an air brakes test if you plan to drive vehicles equipped with air brakes. Before taking the skills test, aspiring commercial drivers must also complete Entry-Level Driver Training (ELDT).

The DMV conducts background checks to ensure that CDL applicants have a safe driving history with no criminal record. Individuals with certain violations may be unable to obtain a CDL. We’ll help you pass the official CDL general knowledge exam by providing you access to an intuitive tool designed to boost your learning potential. Our Connecticut CDL general knowledge exam simulator consists of 50 questions and has been recently updated for October 2025. Each question has multiple answer choices, but only one is correct. You should avoid rushing because scoring in this simulator is just like the official exam. If you make too many mistakes, you fail the test immediately. However, you can always begin a new session since you have unlimited attempts to practice as often as you wish.

There are no shortcuts to your learning phase, and you cannot become an expert overnight. Becoming a professional commercial driver in Connecticut takes time and effort, but we’ll make it easier for you to obtain a CDL and begin your dream career. Start today and train with our Connecticut CDL general knowledge exam simulator for several weeks. On exam day, you’ll already be familiar with the content and format of the official exam.
