Fleet Trucking Insurance: Why Mid-Size Carriers Overpay and What to Do About It

Commercial trucking insurance has become one of the most discussed cost problems in the industry. Premiums hit a record $0.102 per mile in 2024 according to the American Transportation Research Institute (ATRI), representing roughly 10 percent of total operating costs for the average carrier. That number followed a 12.5 percent spike in 2023 and a 3.0 percent increase in 2024. Looking further back, ATRI data shows trucking auto liability premiums rose 36 percent per mile over eight years even as the industry's safety record improved.

Most coverage of this issue focuses on what is driving premiums up: nuclear verdicts, litigation financing, social inflation. That analysis is accurate and important. What it does not address is why mid-size fleets specifically are absorbing a disproportionate share of those increases, and what controllable factors are making their premiums higher than they should be given their actual risk profiles.

This article focuses on that second question. Mid-size operations in the 10 to 100 truck range are not simply victims of an industry-wide pricing environment. They are also, in many cases, paying more than their risk justifies because of four specific and correctable structural problems in how they manage, document, and present their risk to underwriters.

Why Mid-Size Fleets Pay More Per Mile Than Large Carriers

The premium gap between fleet sizes is real and documented. ATRI's operational cost data shows that larger carriers paid approximately 7.7 cents less per mile than small carriers on insurance in recent reporting periods. That is not a rounding error for an operation running millions of miles annually.

The premium gap exists because of how commercial auto insurance underwriting actually works. Insurers start from actuarial tables based on industry-wide claim frequency and severity for motor carriers of similar size, equipment class, and operating territory. They then adjust from that baseline based on verifiable risk data the carrier presents. Large carriers have teams dedicated to managing their risk presentation: safety departments generating continuous documentation, loss control programs with measurable outcomes, and relationships with brokers who specialize in large account transportation coverage.

Most mid-size fleets have none of that infrastructure. They arrive at renewal with a loss run, a basic application, and whatever their broker puts together. Underwriters price what they can see. When they cannot see documented evidence of safety improvement, low CSA scores, telematics data, and driver qualification files, they price at the actuarial baseline or above it. That baseline reflects the industry as a whole, including poorly managed operations. A well-run 40-truck fleet ends up paying rates shaped by the worst performers in its size category because it has not given underwriters the data to price it differently.

The four areas below are where that gap most commonly lives, and where mid-size fleets have the most direct control over their outcomes.

Area 1: The Nuclear Verdict Premium Nobody Explained to You

Before getting into the controllable areas, it is worth understanding the market context that makes all of this more urgent than it was five years ago.

Nuclear verdicts, defined as jury awards exceeding $10 million, increased 52 percent in 2024 according to research cited by AtoB and ATRI. The median nuclear verdict reached $51 million in 2024, up from $44 million in 2023 and just $21 million in 2020. Verdicts exceeding $100 million, now called thermonuclear verdicts, jumped 81 percent to 49 cases in 2024 alone.

The commercial auto liability market has been unprofitable for insurance carriers for 14 consecutive years, according to analysis from Reliance Partners, an industry specialist in transportation insurance. Insurers are not raising premiums because they want to. They are raising premiums because they are paying out more than they collect. That dynamic is not going away.

ATRI's forensic analysis of trucking litigation found that the number of tractor-trailer tort cases filed annually increased at an average rate of 3.7 percent from 2014 to 2023. Plaintiff attorneys have refined techniques including the reptile theory, which frames commercial carriers as threats to public safety to encourage larger jury awards, and litigation financing has lowered the barrier for plaintiffs to pursue large cases by bringing in third-party investors who fund lawsuits in exchange for a portion of the settlement.

Geography matters significantly. ATRI's research identifies California, Georgia, and Florida as states with the highest median verdict awards, often labeled judicial hellholes by defense-side attorneys. Carriers operating heavily in those states carry a material premium penalty that reflects real litigation exposure.

None of these forces are in a fleet director's control. What is in their control is everything that happens before a claim reaches a courtroom, including the documentation, technology, and safety programs that influence whether incidents occur, how they are defended, and how underwriters price the coverage in the first place.

Area 2: Your CSA Score Is Pricing You Out of Preferred Markets

The FMCSA's Safety Measurement System (SMS) generates CSA scores across seven Behavior Analysis and Safety Improvement Categories, or BASICs, for every motor carrier with a DOT number. Underwriters at major commercial trucking carriers pull these scores as a standard part of underwriting evaluation.

Carriers with FMCSA SMS BASIC scores at or above investigation thresholds pay 15 to 30 percent higher premiums consistently, according to data from fleet insurance specialists cited across multiple industry sources. In some cases, elevated CSA scores in certain categories disqualify a fleet entirely from preferred market carriers, forcing it into surplus lines coverage at substantially higher rates.

This is one of the most undermanaged premium drivers for mid-size fleets, and one of the most correctable. CSA scores are calculated from roadside inspection results, crash reports, and investigation outcomes. Unlike claim history, which takes years to improve, CSA scores can improve within months through targeted driver coaching, preventive maintenance compliance, and attention to the specific BASIC categories where the fleet is most exposed.

The seven BASICs are Unsafe Driving, Hours-of-Service Compliance, Driver Fitness, Controlled Substances and Alcohol, Vehicle Maintenance, Hazardous Materials Compliance, and Crash Indicator. For most mid-size carriers, Unsafe Driving and Vehicle Maintenance are the categories generating the most score pressure. Unsafe Driving violations, including speeding, following distance, and cell phone use, are directly influenced by driver behavior monitoring programs. Vehicle Maintenance violations come from deferred preventive maintenance and failed roadside inspections, which are also controllable through disciplined scheduling.

The premium math is direct. A 40-truck fleet paying $600,000 per year in insurance that reduces its BASIC scores below investigation thresholds is looking at a $90,000 to $180,000 annual reduction based on the 15 to 30 percent range documented by underwriting specialists. That improvement does not require years of clean loss history. It requires 12 months of intentional score management documented in a format underwriters can evaluate at renewal.

Area 3: You Are Not Getting Credit for the Technology You Already Have

This is the area where mid-size fleets leave the most money on the ground. The telematics and dashcam infrastructure that most fleets have already deployed for operational and ELD compliance purposes represents a direct negotiating asset with insurance underwriters that most carriers never present correctly.

The data on what that technology is worth to an insurer is now concrete. GEICO's 2025 partnership with Motive established premium discounts of up to 10 percent for fleets that install Motive's driver safety products and agree to share dashcam and ELD data. Progressive's SmartHaul program offers discounts of 5 to 12 percent or more for fleets using approved telematics solutions. Sentry Insurance, in its partnership with Motive, offered up to 5 percent discounts for data sharing, which translates to $10,000 or more in annual savings for large fleets.

More broadly, telematics-equipped fleets are now securing 15 to 30 percent premium reductions while comparable fleets without data programs face double-digit increases, according to fleet insurance analytics published in 2026. Cambridge Mobile Telematics research found a 38 percent reduction in accident frequency for fleets using active telematics programs, and a 40 percent reduction in average claim costs when video evidence was available.

The evidentiary value of dashcam footage in litigation is also documented. One case study from B.A.M. Trucking, cited by Verizon Connect, showed dashcam footage being used to defeat three separate lawsuits from a single claimant, ultimately reducing that fleet's annual insurance premium by $200,000. AAA studies found that fleets with dashcams are 40 percent more likely to have claims settled in their favor and 35 percent faster.

The problem for most mid-size fleets is not that they lack the technology. It is that they are not presenting the data from that technology to underwriters in a structured way at renewal. Many fleets install telematics for dispatch and compliance and then leave the safety behavior data sitting in the platform without ever connecting it to their insurance negotiation. Their broker may not even know the system exists or what data it contains.

This is a structural gap in how mid-size fleets manage the renewal process, not a technology gap. The fix is documentation and presentation, not capital investment. Read how telematics integration reduces insurance costs as part of a broader cost management strategy for more on how leading fleets connect these systems to their financial outcomes.

Area 4: Your Renewal Process Is Working Against You

The fourth area is the one most fleet managers find surprising when they hear it: the process and timing of how you approach renewal has a direct, quantified impact on the premium you receive. It is not just about finding the right carrier. It is about how you arrive at the market.

Industry specialists with deep trucking book expertise consistently document that submissions arriving 90 to 120 days before renewal receive three to five or more competitive quotes, while submissions arriving 15 to 30 days out receive one or two inflated quotes with no negotiating leverage. This is not an anecdote. Underwriters are operating on their own workload schedules, and a rushed submission that arrives late signals both disorganization and desperation, both of which result in higher pricing. Rate filings also update quarterly, and early submissions can lock rates before quarterly increases apply to your renewal.

The broker relationship is a second dimension of the same problem. Many mid-size fleets use general commercial insurance brokers who handle multiple industries rather than specialists who work specifically in trucking and transportation. A generalist broker may not know which markets have appetite for your specific operation, may not know how to present a CSA score trend narrative effectively, and may not have access to specialty transportation programs that offer better rates for well-documented fleets. One industry specialist puts it bluntly: the broker who understands DOT regulations, FMCSA data, loss runs, and fleet operations will present your account to underwriters differently than one who does not, and the resulting premium reflects that difference.

Coverage structure is a third element of the renewal problem. Mid-size fleets frequently carry coverage structures that made sense when the fleet was smaller or operated under different conditions, but have not been reviewed as the operation evolved. Declared operating radius is one of the clearest examples. Underwriters use stated operating radius to set liability tiers. Carriers operating shorter hauls than their filed radius indicates are paying for coverage exposure they are not actually generating. Adjusting stated radius to reflect actual operations can produce 15 percent or more in premium reduction according to commercial truck insurance specialists, and it requires nothing more than an accurate filing.

Putting the Four Areas Together: What the Number Looks Like

For a mid-size fleet running 40 trucks with a current annual premium of $600,000, conservative application of the four areas above produces a specific range of recoverable savings.

CSA score management from above-threshold to below-threshold levels: 15 to 20 percent reduction, or $90,000 to $120,000 per year.

Telematics data presentation and program discounts from carrier partnerships: 5 to 15 percent depending on program and data quality, or $30,000 to $90,000 per year.

Renewal timing and specialized broker access: difficult to quantify precisely, but industry practitioners consistently describe 8 to 15 percent premium improvements from proper market presentation versus rushed late renewals.

Coverage structure correction (operating radius, accurate unit schedules, appropriate deductible levels): 10 to 15 percent depending on how far current structure has drifted from actual operations.

These savings do not stack perfectly, as some improvements compound and some are already captured in others. But a fleet that systematically addresses all four areas over two renewal cycles is looking at a realistic 20 to 30 percent reduction in total insurance cost compared to a fleet doing none of them. On a $600,000 annual premium, that range represents $120,000 to $180,000 per year. Over a five-year period, it is $600,000 to $900,000 in premiums that better-managed fleets keep and poorly-managed ones pay to carriers.

The Relationship Between Insurance and Your Overall Cost Structure

Insurance is one of several major cost categories where mid-size fleets systematically underperform relative to their actual risk profile. Understanding your fleet's cost per mile before a renewal conversation gives you the baseline to evaluate any premium change in terms of its per-mile impact, which is how the number connects directly to your profitability on individual lanes and loads.

The relationship also runs in the other direction. Fleets that reduce fuel waste and fraud through better monitoring programs are, by the same mechanism, reducing the driving behavior risks that generate insurance claims. The telematics program that captures idle time and harsh braking for controlling other major fleet cost categories is the same program that generates the safety data your insurer needs to price you below the actuarial baseline. These are not separate investments. They are one investment producing returns in multiple cost categories simultaneously.

For mid-size fleet directors approaching a renewal in the next 12 months, the practical starting point is a gap analysis against the four areas above, ideally 90 to 120 days before the renewal date. Where does your CSA score sit relative to FMCSA investigation thresholds? What safety data does your telematics platform generate and is it being shared with your insurer? When did you last review your operating radius filings and coverage structure? And when is the last time you evaluated whether your broker has the trucking-specific expertise to present your account effectively?

If you want to explore truck insurance quotes for your fleet size and operation type, having clear answers to those four questions before the conversation starts will directly affect the number you receive.
