CT CDL Pre-Trip Inspection Practice Test 2025
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 CT commercial driver's license manual
- Triple-checked for accuracy
- Updated for March 2025
To obtain a Connecticut Commercial Learner’s Permit (CLP), you must pass the state CDL General Knowledge Exam. Then to obtain a Connecticut CDL, you must hold the CLP and pass the Pre-Trip Inspection Test which is a federal requirement (49 CFR § 392.7 and 49 CFR § 396.13) and one of three parts that must be passed in Connecticut’s CDL skills exam (the pre-trip inspection, the basic control skills test, and the road test). These tests ensure that drivers can recognize and evaluate the condition of their vehicle components. Failing the Knowledge Exam means delaying your CLP by at least one day, as you’ll have to reschedule and likely pay a retest fee. Our Connecticut Pre-Trip Inspection Practice Tests are your key to passing the General Knowledge Test on your first attempt.
The Connecticut General Knowledge Exam and Pre-Trip Inspection Test evaluate your ability to correctly inspect vehicle parts, from engine components to brakes, suspension, and lights. During the pre-trip inspection test, you will be required to point to and explain each component’s function and why it must be checked. Examiners will assess whether you can properly ensure your vehicle is in safe operating condition. Without passing, you will not be granted a CDL, and you cannot drive commercially, though you may still hold a Commercial Learner’s Permit (CLP) for 180 days until it expires. While a CLP allows you to drive with supervision, obtaining a full CDL is necessary for independent commercial driving.
For both the Connecticut CDL General Knowledge Exam and the CDL Pre-Trip Inspection Test, you’ll need to familiarize yourself with the Connecticut Seven-Step Inspection Method, which is a systematic pre-trip vehicle check. It includes reviewing past inspections, inspecting the engine compartment, checking in-cab controls and gauges, verifying lights, conducting a full walk-around inspection, testing signal lights, and assessing the brake system to ensure road safety and compliance.
The practice test is based on the most recent Connecticut CDL manual (Connecticut CDL Handbook 2025) and contains 20 multiple-choice questions to assess your knowledge of pre-trip inspections. It includes a detailed explanation after each response, which speeds learning and helps you pass the official knowledge test on your first attempt.
We have additional practice tests to prepare you for other parts of the General Knowledge Test. Please give them a try!
