Product liability insurance is typically mandated by legislation, the scale of which varies by country and often varies by industry. This type of insurance covers all major product classes and types, including chemicals, agricultural products, and recreational equipment; and protects companies against lawsuits over products or components that cause damage or injury.
Comprehensive insurance is a coverage that helps pay to replace or repair your vehicle if it's stolen or damaged in an incident that's not a collision. Comprehensive typically covers damage from fire, vandalism or falling objects (like a tree or hail). If you're financing or leasing your car, your lender likely requires comprehensive coverage. If you own your vehicle outright, it's an optional coverage on your car insurance policy.
