Understanding Liability Limits in the Personal Auto Policy
In the realm of personal auto insurance, specifically Part A – Liability Coverage, the policy limits represent the maximum amount an insurer will pay for a covered loss. For the Personal Lines Insurance Exam, students must distinguish between two primary methods of expressing these limits: Split Limits and Combined Single Limits (CSL).
Liability insurance is designed to protect the insured’s assets when they are found legally responsible for bodily injury or property damage to others. Because liability claims can vary wildly in severity, understanding how these limits apply to a single occurrence is essential for both the exam and professional practice. For a deeper dive into the broader policy structure, refer to our complete Personal Lines exam guide.
Deconstructing Split Limits (e.g., 100/300/50)
How Split Limits Work
Split limits are the most common way liability coverage is sold in the personal lines market. They are expressed as three separate numbers, usually separated by slashes (e.g., 25/50/10 or 100/300/50). Each number represents a specific cap on a different aspect of the claim.
- Bodily Injury Per Person: This is the maximum amount the policy will pay for injuries sustained by any one individual in an accident.
- Bodily Injury Per Accident: This is the total maximum the policy will pay for all injuries sustained by all persons in a single accident, regardless of how many people are hurt.
- Property Damage Per Accident: This is the maximum amount the policy will pay for damage to the property of others (such as vehicles, fences, or buildings) resulting from a single accident.
It is important to remember that the "Per Person" limit is a subset of the "Per Accident" limit. You cannot pay out more than the per-person limit to any one individual, even if the total per-accident limit has not been reached.
Split Limits vs. Combined Single Limits
| Feature | Split Limits | Combined Single Limit (CSL) |
|---|---|---|
| Structure | Three distinct caps (e.g., 100/300/100) | One single aggregate cap (e.g., $300,000) |
| Flexibility | Rigid; specific caps for BI and PD | Highly flexible; applies to any mix of BI and PD |
| Calculation | Must check per-person, per-accident, and PD caps | One total limit per occurrence |
| Commonality | Standard for most personal auto policies | Often found in commercial or high-limit policies |
Combined Single Limits (CSL) Explained
A Combined Single Limit (CSL) policy uses one single dollar amount to describe the maximum coverage for all bodily injury and property damage claims arising from one accident. For example, a $300,000 CSL policy provides a total of $300,000 that can be used in any combination needed.
The primary advantage of CSL is flexibility. If an accident results in $250,000 of bodily injury to one person and $50,000 in property damage, a $300,000 CSL policy would cover the entire loss. However, under a 100/300/50 split limit policy, the insurer would only pay $100,000 for that individual's injuries and $50,000 for the property damage, leaving the insured personally liable for the remaining $150,000.
Exam Tip: The 'Per Person' Trap
On the exam, watch for scenarios where one person's medical bills exceed the 'Per Person' limit, but the total 'Per Accident' limit is still available. In split limits, the Per Person limit always caps the individual's recovery. You cannot use the remaining 'Per Accident' funds to pay for that specific individual's excess costs.
Practical Calculation Example
Consider an insured with 50/100/25 split limits who causes an accident involving three other people. The damages are as follows:
- Person A: $60,000 (Bodily Injury)
- Person B: $30,000 (Bodily Injury)
- Person C: $10,000 (Bodily Injury)
- Property Damage: $30,000
How much will the policy pay?
- For Person A: The policy pays $50,000 (capped by the per-person limit).
- For Person B: The policy pays $30,000 (fully covered).
- For Person C: The policy pays $10,000 (fully covered).
- Total Bodily Injury paid: $90,000 (This is under the $100,000 per-accident limit, so this is okay).
- For Property Damage: The policy pays $25,000 (capped by the PD limit).
The total payout is $115,000. The insured is responsible for the remaining $10,000 for Person A and $5,000 for property damage. To practice similar scenarios, visit our practice Personal Lines questions.
