Which type of insurance does casualty insurance typically encompass?

Casualty insurance primarily refers to insurance coverage that protects individuals and businesses from loss or damage caused by accidents or unforeseen events. This type of insurance often includes liability coverage, which is a key component of motor vehicle liability insurance.

Motor vehicle liability insurance is essential as it provides protection against claims resulting from injuries or damage to other people or property caused by the insured's vehicle operation. This aligns perfectly with the broader definition of casualty insurance, which emphasizes liability for accidents and incidents that lead to financial loss or injury to others.

In contrast, the other options are not classified as casualty insurance. Property insurance is focused on covering loss or damage to physical assets, health insurance deals with medical expenses and healthcare services, and comprehensive life insurance pertains to the coverage against death, which is distinctly different from the liability and accident-focused nature of casualty insurance. Thus, motor vehicle liability insurance stands out as the correct choice.
