Compulsory and voluntary auto insurance

Why compulsory liability insurance is only the public/legal floor.

Direct answers

Compulsory Automobile Liability Insurance covers limited bodily-injury liability; it does not cover property damage, your vehicle, or all potentially large liability, so assess voluntary cover against those gaps.

Key points

  • CALI/Jibaiseki is mandatory and centered on injury or death to others.
  • Property liability and vehicle damage are outside compulsory cover.
  • Voluntary cover can address third-party limits, property, passengers, legal support, and own damage.
  • Driver, age, use, territory, deductibles, and family definitions can restrict cover.

Start with the compulsory-policy gaps

Confirm the compulsory policy is valid before driving. Then model injury liability above its limits, damage to another vehicle or property, your own injuries and vehicle, roadside needs, and who will drive. A private comparison that starts with premiums rather than these gaps is incomplete.
