PA CDL General Knowledge Exam Simulator 2025

5 min

Commercial drivers in Pennsylvania have a wide range of jobs to choose from. Industries such as manufacturing, distribution, and agriculture require a constant flow of goods across the Keystone State. However, delivering heavy equipment and transporting hazardous materials are difficult tasks involving great responsibility. Since even a small mistake can lead to disaster, road safety is an important topic that should be prioritized in your study sessions. In Pennsylvania, you will encounter varying road conditions. From busy cities like Philadelphia to rural highways, you must be ready for anything. The official Pennsylvania commercial driver’s manual (Pennsylvania CDL Handbook 2025) contains useful information on the various aspects of commercial driving theory. We recommend reading its contents at least once before incorporating other tools into your study routine.

The official CDL General Knowledge (permit) exam consists of 50 multiple-choice questions. You must answer them before the timer ends and score 80% or higher to pass. If you fail, you must pay a re-test fee and retake the exam no sooner than the next business day. Don’t rely on luck to pass. Instead, you should use our Pennsylvania CDL General Knowledge Exam Simulator to prepare in advance and build the knowledge and confidence necessary to obtain a passing score on your first attempt. You get unlimited attempts and nonstop access to this intuitive tool, which can be used even by those not skilled with computers. We have opted for a simple interface and omitted any timer for your convenience.
