Definition:Split limit
📋 Split limit is a liability insurance structure that breaks coverage into separate maximum payouts for different categories of loss within a single policy, rather than providing one combined amount for all damages. In auto insurance, the most familiar example is the three-way split expressed as bodily injury per person / bodily injury per accident / property damage — such as 100/300/50 (in thousands). This approach gives underwriters granular control over exposure and allows carriers to price each component of risk independently.
🔍 Under a split-limit structure, each sub-limit acts as an independent ceiling. Consider a commercial auto policy with $250,000 per person, $500,000 per accident for bodily injury, and $100,000 for property damage. If a covered driver causes a multi-vehicle collision injuring three people, the insurer's bodily injury obligation to any one claimant tops out at $250,000, with total bodily injury payments for that single accident capped at $500,000 — regardless of how many people are injured. Property damage to vehicles and structures is handled separately under its own sub-limit. Claims adjusters must allocate losses across each bucket, and policyholders can face coverage gaps when a severe loss exhausts one sub-limit even though another remains untouched.
⚖️ Contrasting split limits with a combined single limit highlights the trade-offs insurers and insureds negotiate. Split limits typically produce lower premiums because the insurer's maximum exposure is more tightly compartmentalized, but they offer less flexibility when a loss is heavily weighted toward one damage category. From a carrier's perspective, split limits simplify reserving and loss-ratio projections because each sub-limit constrains volatility within defined boundaries. For commercial lines buyers, understanding the interplay between sub-limits is essential to avoid underinsurance — a reality that brokers routinely address during the placement process.
