Category Breakdown
Premium Savings
Self-Insured Retention (SIR) winsSIR programs typically reduce premiums by 20-40% compared to traditional deductible policies. The insurer shifts more risk to you, which is reflected in lower premium payments. For well-managed fleets with strong safety records, the savings are substantial.
Cash Flow Impact
Traditional Deductible winsSIR requires significant cash reserves to cover claims within the retention amount. A $100,000 SIR means you pay the first $100,000 of every claim from your own funds. Traditional deductibles are much smaller ($1,000-$10,000), requiring less capital.
Claims Control
Self-Insured Retention (SIR) winsSIR gives you control over claims handling within the retention amount. You choose the defense attorneys, control settlements, and manage costs. Traditional policies hand claims control to the insurer from the first dollar.
Risk Exposure
Traditional Deductible winsSIR exposes you to more financial risk per claim. A bad year with multiple large claims can strain cash reserves. Traditional deductible policies protect cash flow at the cost of higher premiums.
Fleet Size Suitability
Traditional Deductible winsSIR makes financial sense for fleets with 50+ trucks and $500,000+ in reserves. Smaller fleets cannot absorb the per-claim exposure. Traditional deductibles are appropriate for any fleet size.

Our Verdict
Traditional deductible insurance wins for most trucking operations because it provides predictable costs and protects cash flow. The premium is higher but the financial risk per claim is lower.
SIR wins for large, well-capitalized fleets with strong safety programs that consistently generate fewer and smaller claims than average. The premium savings compound significantly at scale — a 100-truck fleet saving 30% on premiums recovers $200,000+ annually.
Fleets under 50 trucks: traditional deductible. Fleets over 50 trucks with strong safety: evaluate SIR with an experienced insurance broker.
