A more thorough explanation:

Definition: Additional insurance refers to any extra coverage that is added to an existing insurance policy. This can include additional coverage for specific risks or events, or additional insured parties.

Example: If you have a car insurance policy that only covers liability, you may choose to add additional insurance for collision or comprehensive coverage. This would provide extra protection in the event of an accident or other damage to your vehicle.

Another example of additional insurance is adding an additional insured party to a policy. For example, if you are a landlord renting out a property, you may require your tenants to have renters insurance with you listed as an additional insured party. This would provide you with additional protection in the event of any damages or liability issues related to the rental property.

These examples illustrate how additional insurance can provide extra protection and coverage beyond what is included in a standard insurance policy.
