CDL Testing What You Need to Know as a Truck Driver

A Commercial Driver's License (CDL) is required for anyone who wants to operate a commercial vehicle, including tractor-trailers, buses, and other large trucks. To obtain a CDL, truck drivers must pass a series of tests designed to evaluate their knowledge, skills, and ability to operate a commercial vehicle safely and responsibly. Here's what you need to know about CDL testing:

Requirements: To be eligible for a CDL, you must be at least 18 years old (21 for interstate driving), have a valid driver's license, and pass a medical examination. You must also meet specific requirements based on the type of vehicle you plan to drive.

Knowledge Test: The CDL knowledge test evaluates your understanding of the rules and regulations of operating a commercial vehicle, including safety procedures, traffic laws, and vehicle maintenance. The test typically consists of multiple-choice questions and requires a passing score of at least 80%.

Skills Test: The CDL skills test evaluates your ability to operate a commercial vehicle safely and effectively. It consists of three parts: a pre-trip inspection, a basic control skills test, and an on-road driving test. The skills test is conducted by a certified examiner and requires a passing score of at least 80%.

Endorsements: Depending on the type of commercial vehicle you plan to drive, you may need to obtain additional endorsements on your CDL. These endorsements may include Hazardous Materials (HazMat), Passenger, or Tanker endorsements, among others.

Renewal and Retesting: CDLs must be renewed every four to five years, depending on the state. To renew your CDL, you may need to retake the knowledge and skills tests, depending on your state's requirements.

Resources: To prepare for CDL testing, truck drivers can access a variety of resources, including online study guides, practice tests, and training programs. Many truck driving schools also offer CDL training courses to help drivers prepare for the tests.
