The Hawaii Road Signs & Driver Knowledge Test is the written exam every new driver must pass to earn an instruction permit in the state. It's administered by the Hawaii Department of Transportation (HIDOT) together with the county driver licensing divisions in Honolulu, Hawaii, Maui, and Kauai. Teens and adult first-time applicants alike take this same knowledge test before they can begin supervised driving.

Overview

Rather than splitting road signs into their own standalone exam, Hawaii folds sign recognition and traffic control devices into one combined knowledge test alongside rules-of-the-road questions and a vision check. Applicants also complete a separate practical road test later, once they've held their instruction permit long enough.

  • Vision test
  • Knowledge test covering traffic signs, signals, and rules of the road
  • Practical road test (taken later, before a provisional license)

Because signs and rules are tested together rather than in a dedicated signs-only section, practicing sign recognition alongside general road-rule questions best matches how the real test is structured.

Cost and registration

Knowledge test fees are set by county rather than statewide: $11.00 in Hawaii County, $12.00 in the City and County of Honolulu, $20.00 in Kauai County, and $25.00 in Maui County. Always confirm current pricing with your county driver licensing division before your test date, since fee schedules can change.

Exam format

The knowledge test consists of 25 questions with a one-hour time limit, offered in both English and Spanish. Hawaii has not published an official minimum passing score, so applicants should aim to answer confidently across all sign and rule categories rather than target a specific number. The test can be taken online statewide from home, or in person at a county licensing center on a limited, appointment-only basis.
