Six Years of Rising Premiums. Why Fleet Insurance Is a Structural Problem — Not a Bad Year.
Commercial auto insurance has increased every single quarter for the past six years. If your fleet's renewal feels worse than last year's, that wasn't bad luck or a bad broker — it was arithmetic catching up. The question isn't whether your premium is going up again. The question is how far, and what you're doing to influence the number.
The Scale of the Problem
The American Transportation Research Institute's 2025 Operational Costs of Trucking report put commercial auto insurance at a record $0.102 per mile in 2024, the highest the metric has ever been. The Council of Insurance Agents & Brokers confirmed a 7.5 percent commercial auto rate increase in Q4 2025 — the 24th consecutive quarter of increases. For a delivery fleet running 20 vehicles at 200 or more daily miles each, the compounding effect of 24 straight quarters of above-inflation increases is not a rounding error. It's a structural cost shift.
Some operators have seen far worse than average. The CIAB's Q4 2025 survey noted that high-exposure commercial auto accounts — those with recent at-fault claims or gaps in documented safety practices — faced renewal increases meaningfully above the 7.5 percent average, with some accounts seeing premium adjustments in the 15 to 40 percent range depending on claims history and documentation practices.
Why Underwriters Are Repricing Commercial Auto
The root cause is litigation, not accidents. Nuclear verdicts — jury awards exceeding $10 million against commercial vehicle operators — surged 52 percent in 2024, reaching 135 cases totaling $31.3 billion, according to Risk & Insurance magazine. The median nuclear verdict climbed from $21 million in 2020 to $44 million in 2023 to $51 million in 2024. A fleet running 30 vans with one serious at-fault accident is now operating in a litigation environment where the potential exposure on that single claim has roughly doubled in four years.
ATRI's research on trucking litigation specifically puts the trajectory in stark terms: verdicts against trucking and delivery operators rose 967 percent between 2010 and 2023, with average awards climbing from $2.3 million to $22.3 million over that span. Insurers underwriting commercial auto are pricing for a litigation environment that looks fundamentally different than the one they were writing against a decade ago. The consecutive premium increases are a repricing — not an anomaly — and that repricing isn't finished.
What Underwriters Are Actually Weighting
What changes an underwriting outcome for a delivery fleet isn't routes or vehicle age in isolation. It's documented risk management — the kind you can hand to an underwriter and let it speak for itself. That shift is visible in the products being offered. Telematics-based underwriting, dashcam requirements, and formal driver monitoring programs are moving from optional to standard in commercial auto policies covering delivery fleets.
AXA XL data on fleet dashcam feedback programs shows 60 percent fewer incidents and 86 percent lower accident costs among fleets with active driver coaching loops compared to those running without them. Munich Re has documented 15 percent premium rebates for fleets with telematics-enabled coaching programs in qualifying markets. Progressive and HDVI — two carriers active in the last-mile fleet space — offer 5 to 20 percent savings for operators who share video and telematics data for underwriting purposes.
The logic from an underwriter's perspective is clean: a fleet with documented driver monitoring, maintained vehicle inspection records, and a verifiable claims history is not the same risk as one operating on paper routes and manual logs. They don't price it the same way.
What This Means for Fleet Operators Right Now
Insurance is no longer a line item to accept at renewal and move on. It's a category where documented operations produce measurable cost advantages over undocumented ones — and where the gap between those two positions is widening as carriers increasingly differentiate on data.
The fleets being hit hardest at renewal tend to share two characteristics: recent at-fault claims and limited documentation of safety practices. The fleets seeing the most manageable increases are running dashcams with active coaching, sharing telematics data with their carriers, and maintaining records that allow underwriters to underwrite rather than estimate.
You may not be able to move your premium down in a market that's increased 24 consecutive quarters. But you can move it down relative to what it would be without the documentation. That gap — between what you pay and what an undocumented fleet pays — is where documented operators build a lasting cost advantage. In an environment where every operator's premium is rising, the ones who survive and scale are the ones whose costs rise more slowly.

Frequently Asked Questions
Why is commercial fleet insurance so expensive for DSPs? Commercial auto insurance for last-mile delivery fleets has increased every quarter for six consecutive years. The primary driver is not accident frequency — it's nuclear verdicts in litigation, where jury awards in commercial vehicle accidents regularly exceed $10M. Insurers price this litigation risk into premiums regardless of individual fleet safety records.
How much has DSP fleet insurance increased? Commercial auto rates for delivery fleets have increased an estimated 50–70% cumulatively since 2019. A fleet that paid $280/van/month in insurance in 2019 is paying $420–$480/van/month in 2026 for equivalent coverage.
What can DSP operators do to reduce insurance premiums? Documented safety programs, dash cam footage, driver training records, and claims history directly influence underwriter pricing. Operators with clean 3-year claims records and documented safety programs typically negotiate 15–25% lower rates than operators without this documentation.
