Washington knowledge-test format
Washington DOL lists a 50-question general knowledge test with 40 correct needed to pass. Separate tests cover combination vehicles, air brakes, passenger, school bus, doubles/triples, tank vehicles, and hazardous materials. The exact set depends on your class, equipment, and endorsements. Knowledge testing is by appointment at licensing offices that offer tests; the state lists English, Spanish, Russian, and Serbian–Croatian, and does not allow interpreters.
Washington’s minimum training requirements
The state lists 160 minimum hours for an original Class A, 80 for Class B and Class C, and separate training-hour requirements for upgrades and endorsements. Only a registered Washington training provider may certify completion. Use the current Department of Licensing requirements page to confirm the path for your license and endorsement combination.
Use the updated skills-test guide
Washington DOL says the vehicle-inspection and basic-control sections of its older CDL guide have been replaced by a supplemental guide. Review the supplement for those test segments and the main commercial driver guide for the remaining material.
