What this exam covers
Real Hawaii CDL requirements

The knowledge tested here is federal (FMCSA) and identical nationwide -- what varies by state is who administers it and under what terms. Researched directly from County-administered driver licensing under the Hawaii Department of Transportation (HDOT) -- CDL services are run by each of Hawaii's four counties (Honolulu, Hawaii, Maui, Kauai), not a single statewide DMV's own site, verified 2026-09-03.

Administering agency
County-administered driver licensing under the Hawaii Department of Transportation (HDOT) -- CDL services are run by each of Hawaii's four counties (Honolulu, Hawaii, Maui, Kauai), not a single statewide DMV
Spanish-language knowledge test
Unconfirmed

HDOT confirms (hidot.hawaii.gov Administration news release) that the Hawaii State Driver's Manual is available in 13 languages other than English, including Spanish, and states the driver licensing knowledge test is "already currently available" in those languages -- but this announcement is about the REGULAR driver's manual/test, and this research could not confirm it applies to the CDL knowledge test specifically, especially since CDL testing in Hawaii is administered at the county level (e.g., Hawaii County's Vehicle Registration & Licensing office) and county pages could not be fetched directly (403 errors) to verify. Because Hawaii's CDL program is county-run, language policy could plausibly vary by county. This needs direct county-by-county confirmation before publishing a Spanish-availability claim.
