CDL General Knowledge: Coverage Map & Learning Gaps

Core commercial-driving general knowledge; using an official state manual for common principles, not every state requirement or endorsement

A partial map, not a completion score.

Local topic IDs organize official handbook rules; they are not official blueprint identifiers. Archive topic proportions guide allocation only.

Mapping describes the available practice, not your mastery or readiness for the exam. Reviewed 2026-10-27.

Use the map with care.

  • General knowledge foundations only; air-brake, combination, tanker, passenger, school-bus, doubles/triples, and hazardous-material endorsement coverage is incomplete.
  • The retained Washington official guide supports common principles; current licensing procedures and local legal requirements must be checked with the issuing state.
  • Multiple contexts share a rule family;200 items do not mean200 independent rules.
  • Professional CDL-instructor review and learner calibration remain pending.
