In rear-end collisions, the victim's fault ratio is typically 0%. Since the victim's insurer cannot negotiate on their behalf (Attorney Act Art. 72), victims must negotiate directly or hire an attorney. Three compensation standards exist: CALI standard (¥4,300/day, minimum), voluntary insurance standard (slightly higher, undisclosed), and attorney/court standard (2-3x CALI, based on "Red Book"/"Blue Book"). Damages include medical expenses, lost income, pain and suffering, and disability benefits (Grade 14: ¥1.1M to Grade 1: ¥28M). Attorney cost insurance (弁護士費用特約) typically covers up to ¥3M.
