What is a "rider" or "endorsement" in insurance terminology?

In insurance terminology, a "rider" or "endorsement" refers to an addition that modifies the coverage or terms of an existing insurance policy. This allows policyholders to customize their insurance coverage to better fit their specific needs or to include additional protections that aren't part of the standard policy. Riders can enhance coverage, add exclusions, or adjust the terms of the policy, thus providing flexibility to the insured.

For example, a homeowner might choose to add a rider to their policy that covers jewelry or fine art that exceeds the standard coverage limits. By doing so, the homeowner ensures that these valuable items are adequately protected. This ability to modify existing policies is essential in the insurance industry, catering to the unique circumstances and requirements of individual policyholders.

The other choices do not accurately describe a rider or endorsement. A decrease in policy premiums does not relate to modifications in coverage. Optional coverage included in a policy may refer to coverage that can be selected initially but does not imply changes to existing terms or provisions. Lastly, a cancellation notice pertains to the termination of an insurance policy, which is unrelated to the addition or modification of coverage.
