Casualty Insurance Policy Types and Coverages
Personal auto
A personal auto policy has five parts: A liability, B medical payments, C uninsured/underinsured motorists, D collision, and other than collision (comprehensive). Coverage may be written as split limits (25/50/25) or a combined single limit. New Hampshire's compulsory requirements - liability limits of 25/50/25, medical payments of at least $1,000, and uninsured motorist coverage at the liability limits - are frequently tested. Key definitions include owned auto, newly acquired auto (covered for a short grace period without notice), temporary substitute, and non-owned auto. Common exclusions: intentional acts, racing, livery use, and carrying property for a fee.
Commercial casualty
Business auto uses numbered symbols to describe covered autos; garage coverage adds garagekeepers and dealer exposure. The CGL provides Coverage A (bodily injury and property damage), B (personal and advertising injury), and C (medical payments), with limits for general aggregate, products-completed operations aggregate, each occurrence, damage to premises rented to you, and medical expense. Umbrellas sit over underlying policies and may drop down or apply a self-insured retention. Workers compensation has three parts: Part One statutory benefits with no dollar limit, Part Two employers liability, and Part Three other states. Professional liability, E&O, D&O, and cyber are typically claims-made.
Worked example
Employers liability limits of 500/500/500 mean $500,000 each accident, $500,000 disease each employee, and $500,000 disease policy limit. Part One above them has no stated limit - it pays whatever the statute requires.
Traps
Assuming Part One of workers compensation has a dollar limit; expecting the CGL to pay for employee injuries; mixing up the three employers liability limits; and treating an umbrella as having no retention or no underlying requirement.
