Hawaii Car Accidents: fault-allocation pressure, decision sequencing, and when review matters

Hawaii's car accident law begins with a fundamental difference from most states: Hawaii is a no-fault insurance state under the Hawai'i Motor Vehicle Insurance Law (HRS §§ 431:10C-101 et seq.). Every registered vehicle in Hawaii must carry Personal Injury Protection (PIP) of at least $10,000 per person — and in a no-fault system, an injured driver turns first to their own PIP coverage for medical expenses and lost wages, regardless of who caused the accident. PIP pays without regard to fault for the first $10,000 in eligible medical treatment costs. To step outside the no-fault system and pursue the at-fault driver in tort, a Hawaii accident victim must meet the tort threshold: either the injured person's medical treatment costs from the accident exceed $5,000, OR the injury involves death, significant permanent disfigurement, or significant permanent loss of use of a body part or function. This threshold filters out minor soft-tissue cases from the tort system while preserving the right to full tort recovery for serious injuries. Hawaii is also a pure comparative fault state — a plaintiff who is 99% at fault for the accident may still recover 1% of their damages from a 1%-at-fault defendant.

Hawaii's road geography creates distinct accident patterns across the island chain. On O'ahu — home to approximately 70% of Hawaii's population and to the City and County of Honolulu — the H-1 freeway (the Lunalilo Freeway, running east-west across O'ahu from Halawa in the west to downtown Honolulu) is consistently ranked among the most congested roadways in the United States relative to its size, with commuter traffic from the 'Ewa Plain, Kapolei, and Central O'ahu competing for limited freeway capacity. Maui's Road to Hana (State Route 360) — a 64.4-mile two-lane coastal road with 620 curves and 59 bridges crossing streams to the Hana district of East Maui — is one of the most accident-prone tourist routes in the state, with rental car drivers unfamiliar with the road's challenges. On the Big Island (Hawai'i County), the chain of craters road and Saddle Road (Route 200 — the high-altitude route crossing the Pohakuloa Training Area between Hilo and Kona) present weather and visibility challenges distinctive to a volcanic island.
