What is the CDL General Knowledge exam?
The CDL General Knowledge exam is the written knowledge test required before you can get a Commercial Learner’s Permit (CLP) and later a Commercial Driver’s License (CDL) for Class A or Class B vehicles. It covers vehicle systems, safe driving, cargo, and hours-of-service style rules from the FMCSA Commercial Driver’s Manual — not the skills/road test. States administer the test through their DMV or equivalent; you typically must pass General Knowledge (and any required endorsement knowledge tests) before scheduling skills testing.
Administered by: State DMV / licensing agency, using FMCSA Commercial Driver’s Manual topics
Official format: Written (or computer-based) multiple-choice knowledge test; length and pass score vary by state. Skills/road testing is separate after you hold a CLP.

What is the CDL General Knowledge exam?
It is the core written knowledge test for a Commercial Learner’s Permit / CDL. It checks whether you understand commercial vehicle operation, safety, and cargo rules before you take the skills test.
Is CDL General Knowledge the same as the skills test?
No. General Knowledge is a knowledge (written) exam. The CDL skills test (vehicle inspection, basic controls, and road test) is a separate step after you get a CLP and practice.
