Pennsylvania CDL Test Prep is a comprehensive test prep platform designed to help students pass the Pennsylvania Commercial Driver License (CDL) written exam. Developed by Kelvin Beecroft, this app has been used by over 800,000 students since 2009.

The program includes a wide range of study aids, including a Pennsylvania CDL license/permit practice test with over 580 questions, the Pennsylvania CDL Manual, and free access to road signs. It covers all the necessary sections, such as Air Brakes, Combination Vehicles, Driving Safely, and Hazardous Materials, among others.

One of the standout features of this program is the availability of cheat sheets, which can be printed, copied to iBooks, or used within the built-in reader. Cheat sheets are available for Air Brakes, Passenger, Cargo, and School Bus topics.

The app also offers useful features like the ability to preview answers to practice questions, bookmark questions for later review, and immediate answer checking and explanations in study mode. Additionally, users can share questions on Facebook to seek help from friends. The app intelligently avoids repeating questions until a topic is complete and automatically saves practice tests for easy continuation.

Developed by an expert driver and based on the work supported by the Federal Motor Carrier Safety Administration, Pennsylvania CDL Test Prep is a valuable resource for anyone preparing for the Pennsylvania CDL written exam.
