Dash cams are legal in Hawaii but must not obstruct the driver’s view, with strict mounting rules updated in 2026. The state’s “Eyes on the Road” program even distributes free units to crowdsource safety data.
Mounting Requirements
HRS § 291-21.5 prohibits windshield objects blocking vision; dash cams limit to 5-square-inch areas in top/bottom corners or dashboard/rear window spots. 2026 amendments ban improper phone mounts/dash cams blocking any forward view—keep low near dash. No screens visible while driving if distracting.
Audio Recording Rules
Hawaii requires one-party consent for audio (HRS § 803-42), so record legally if you’re party to conversations. Disable audio for passengers to avoid eavesdropping claims—video-only suffices for roads.
Privacy and Evidence
No audio PII issues on public roads; footage admissible in court if compliant (e.g., accidents). “Eyes on the Road” cams blur faces/plates, upload anonymously to HDOT for potholes/guardrails via AI—no personal tracking. Submit reckless driving clips to police via app.
State Program Details
HDOT/UH Mānoa/Blyncsy offer 1,000 free Nextbase cams (Jan 2026 rollout): front-view only, no audio, cloud AI analysis for maintenance. Apply at eng.hawaii.edu/eyes-on-the-road; prioritized by coverage. Users report road rage via app—evidence parameters pending.
Enforcement and Fines
Obstruction tickets: $100-$200+ points. Courts suppress non-compliant footage. Commercial vehicles follow FMCSA—no extra state hurdles.
