About 7CDL
Who operates this site
7CDL is an independent educational project operated by Viralink LLC, based in Utah, United States. It offers CDL study materials in English, Spanish and Arabic.
Learn here, then practice
The curriculum covers General Knowledge, Air Brakes, Combination Vehicles, endorsements and theory for skills preparation. Lessons, explanations and practice questions are available on this site. Reference links let you check the source without replacing the lesson.
Scope
7CDL is not a government agency, official testing service or ELDT training provider. It is not affiliated with FMCSA, AAMVA or state licensing agencies. Practice questions are educational exercises, not an official examination bank.
Editorial approach
Each lesson identifies a manual section. State pages link facts to source documents and identify incomplete collections. A collection date does not mean that every fact has received expert approval. The current lesson and question collection is awaiting technical, translation and source-rights review before public launch.
Corrections and updates
Before public launch, the operator will activate a contact channel for corrections. A useful report includes the page, the disputed statement and an official reference. Published corrections should record what changed and when.
