1. In a 25/50/20 split-limit auto policy, the third number represents the maximum the insurer will pay for:

Property damage liability per accident

In split limits, the third number is the property damage liability limit per accident; in Oregon's minimum that figure is commonly cited as 20,000 dollars.

2. Under a 25/50/20 auto policy, if one person is injured and incurs 40,000 dollars in covered bodily injury, the most the insurer pays that person is:

25,000 dollars

The per-person bodily injury limit caps payment for any one person at 25,000 dollars, so the insurer pays 25,000 and the rest is unrecovered from this coverage.

3. Under 25/50/20 limits, the most the insurer will pay in total for bodily injury to all persons in one accident is:

50,000 dollars

The second number is the per-accident bodily injury limit, capping total bodily injury payments for all persons at 50,000 dollars.

4. Underinsured motorist coverage is designed to protect the insured when the at-fault driver:

Has liability limits too low to cover the insured's injuries

Underinsured motorist coverage applies when the at-fault driver has some liability insurance but not enough to fully cover the insured's injuries.
