Split Limit vs. Combined Single Limit: Choosing the Right Car Insurance

Auto insurance is an essential part of protecting yourself, your passengers, and others on the road. Understanding the nuances of coverage can be a bit tricky, but is necessary to make the right decision and get the most bang for your buck.

Tennessee Car Insurance Overview

Two common types of liability coverage in auto insurance are split limit policies and combined single limit (CSL) policies. Each has unique features, advantages, and potential drawbacks. For Tennessee residents navigating these options, this comprehensive guide breaks down the differences, compares the benefits and limitations, and helps you determine the best fit for your needs.


What Are Auto Liability Limits?

Auto liability insurance is designed to cover damages you might cause to others in an accident, whether to their property or as bodily injury. Liability coverage is mandatory in Tennessee, with state minimum requirements set at:

  • $25,000 for bodily injury per person,
  • $50,000 for bodily injury per accident, and
  • $25,000 for property damage.

These figures are expressed as split limits, but many insurance companies also offer combined single limit policies. Let’s explore both types in detail.


What Is a Split Limit Auto Policy?

A split limit policy divides liability coverage into three distinct components:

  1. Bodily Injury Per Person: The maximum amount the policy will pay for injuries to a single person.
  2. Bodily Injury Per Accident: The total maximum amount the policy will pay for injuries to all individuals in one accident.
  3. Property Damage: The maximum amount the policy will pay for damage to others’ property.

For example, a split limit policy of 50/100/25 means:

  • $50,000 is available for bodily injury to one person.
  • $100,000 is available for total bodily injury to all people involved in the accident.
  • $25,000 is available for property damage.

What Is a Combined Single Limit (CSL) Auto Policy?

A combined single limit policy provides one total coverage amount for all liability costs—bodily injury and property damage—arising from a single accident.

For instance, if your CSL policy has a limit of $300,000, that amount can be allocated in any way to cover bodily injury or property damage, without sub-limits.


Key Differences Between Split Limit and CSL Policies

  1. Allocation of Coverage
    • Split Limit: Coverage is segmented into predefined limits for bodily injury per person, total bodily injury, and property damage. If damages exceed one sub-limit, you’re responsible for the remaining costs, even if another sub-limit is underutilized.
    • CSL: Offers greater flexibility by combining bodily injury and property damage into a single pool. This flexibility can prevent coverage shortfalls in cases where property damage or bodily injury costs are disproportionately high.
  2. Premium Costs
    • Split Limit: Typically less expensive because the segmented coverage limits the insurer’s financial exposure.
    • CSL: Premiums tend to be higher due to the policy’s flexibility and broader coverage.
  3. Claims Handling
    • Split Limit: Claims are processed within the constraints of individual sub-limits. This can lead to situations where one limit is exhausted while another remains untouched.
    • CSL: Claims are paid from a single limit, simplifying the claims process and reducing the risk of out-of-pocket expenses for policyholders.
  4. Simplicity
    • Split Limit: May require more understanding of how sub-limits interact and their implications during a claim.
    • CSL: Offers straightforward coverage, with one comprehensive limit that avoids the complexities of sub-limits.

The Pros and Cons of Split Limit Policies

Pros:

  1. Affordability: Split limit policies are generally more affordable than CSL policies, making them an attractive option for cost-conscious drivers.
  2. Meets Minimum Requirements: These policies can easily meet Tennessee’s state minimum liability requirements.
  3. Customization: You can often choose specific limits that align with your budget and needs.

Cons:

  1. Coverage Gaps: If bodily injury or property damage costs exceed the sub-limit, you’re responsible for the difference. For example, if property damage costs $30,000 but your property damage limit is $25,000, you must pay the additional $5,000.
  2. Less Flexibility: Unused funds in one sub-limit cannot be reallocated to another area.
  3. Complicated Claims: Understanding and navigating sub-limits can be challenging during the claims process.

The Pros and Cons of Combined Single Limit Policies

Pros:

  1. Flexibility: CSL policies allow the entire coverage amount to be allocated as needed, reducing the risk of out-of-pocket expenses for liability claims.
  2. Simplicity: Having one limit simplifies understanding and managing coverage.
  3. Better for High-Risk Scenarios: CSL policies are ideal for drivers who frequently drive in areas with expensive vehicles or higher accident risks, where property damage costs may exceed split limit caps.

Cons:

  1. Higher Premiums: The added flexibility and comprehensive nature of CSL policies come with increased costs.
  2. Overinsuring Risk: Drivers with minimal risk exposure may find CSL policies unnecessary, given their higher premiums.

Examples of Split Limit and CSL Scenarios

To illustrate the practical differences, let’s consider a real-world scenario:

Accident Scenario:
You cause a collision involving three vehicles. Two people are injured, and the total costs are:

  • Bodily Injury (Person 1): $60,000
  • Bodily Injury (Person 2): $40,000
  • Property Damage: $70,000

Split Limit Policy (50/100/25):

  • Bodily Injury Per Person: $50,000 paid for Person 1; you owe $10,000.
  • Total Bodily Injury: $90,000 total paid (within the $100,000 limit).
  • Property Damage: $25,000 paid; you owe $45,000.
  • Out-of-Pocket Total: $55,000

Combined Single Limit Policy ($300,000):

  • The $300,000 limit covers all liability costs: $60,000 for Person 1, $40,000 for Person 2, and $70,000 for property damage.
  • Out-of-Pocket Total: $0

How Tennessee Residents Should Choose Between Split Limit and CSL Policies

When a Split Limit Policy May Be Right for You

  • You’re on a tight budget and need a cost-effective way to meet Tennessee’s minimum liability requirements.
  • You drive infrequently or in low-risk areas with minimal exposure to high-value vehicles or heavy traffic.
  • You have other financial protections in place, such as an umbrella insurance policy, to cover potential gaps.

When a Combined Single Limit Policy May Be Right for You

  • You prefer comprehensive protection and want to minimize the risk of out-of-pocket costs.
  • You frequently drive in urban areas, where accidents may result in higher property damage costs.
  • You own valuable assets that could be targeted in a lawsuit if your liability coverage is insufficient.
