Commercial auto insurance is one of those line items that rarely sits still. Fleet sizes ebb and flow, routes expand, contracts change, and the underwriting picture shifts with every renewal cycle. Among all the moving parts, one variable exerts outsized pressure on what you pay: your claims history. Insurers treat it as a living record of risk, a data trail that predicts what tomorrow might bring based on what yesterday already did.
Insurers don’t look at claims in a vacuum. They parse the frequency, severity, fault, lag time, and loss types across multiple years, compare the results to others in your industry, and then translate that profile into a premium and often a best commercial van insurance set of conditions. The same loss runs can lead to vastly different outcomes depending on how well you explain the story behind them and what operational changes you made afterward. Understanding how underwriters think about claims, and what you can do to shape that conversation, gives you leverage you won’t get from shopping rates alone.
What underwriters really see when they read your loss runs
Loss runs are the official record of reported claims: dates, types of accidents, reserves, paid amounts, subrogation, and closures. Underwriters scan them with a few questions in mind: how often do losses happen, how bad do they get, and what will this book of business look like in the next term. If you imagine a claims spreadsheet as a flat file, underwriters see layers.
They start with frequency. Five fender benders in a year will get more attention than one major crash over three years, even if the total dollars are similar. Frequent, low-severity losses suggest systemic issues: rushed schedules that breed tailgating, poor backing protocols in tight yards, or high turnover that forces you to train on the fly. Frequency is contagious in actuarial models. It predicts future activity and introduces uncertainty, which carriers price in.
Severity sits right behind it. A single loss that pierces policy limits can overshadow years of clean operations. Large bodily injury or wrongful death claims warp the loss ratio and reflect tail risk that can’t be offset by clean periods. When reserves spike or drag over multiple years, the carrier assumes volatility that needs a wider premium margin.
Underwriters also separate at-fault collisions from not-at-fault events and scrutinize preventability. A rear-end crash by your driver at 6:30 a.m. in the rain reads differently than being rear-ended while stopped at a light. Cargo theft looks different from a sideswipe on an interstate merge. Two similar paid amounts, two different underwriting interpretations.
Timeliness matters. Late reporting keeps adjusters from preserving evidence and tamping down costs. If your loss runs show claims reported 30 or 60 days after an incident, that pattern tells an underwriter you have a lag in supervision, telematics alerts, or incident culture. Claims that hang open for long stretches also raise eyebrows. An open file is a wildcard, and carriers reserve against it accordingly.
Finally, they look for clusters. If six claims involve the same terminal, the same customer yard, or the same route segment, the issue might be the physical environment rather than the drivers. Patterns like that can be fixable, and proof you addressed them becomes underwriting gold.
The time window that counts
Most carriers analyze a three to five year loss period, usually valued as of a recent date like 90 days prior to binding. That window balances recency with enough data to show patterns. A bad year does not doom you forever, but it will be weighted more heavily in the next one or two renewal cycles. Some carriers use credibility weighting, giving the most recent 12 to 24 months extra influence if exposure has been stable. If your fleet doubled, they normalize the data to a per-unit or per-mile basis to avoid penalizing growth.
Here is the nuance: claims don’t age off evenly. A large claim that remains open, even if it occurred four years ago, can dominate the picture at renewal. Conversely, a string of small not-at-fault glass claims two and three years back may carry little weight if the last 18 months are quiet.
How loss ratio becomes a price
Loss ratio is a shorthand many agents use at a renewal meeting. It’s the claims costs divided by the premium earned over a period. At a basic level, a 40 percent loss ratio looks good, 70 percent raises questions, and anything north of that gets attention. But underwriting isn’t a straight line from loss ratio to premium. Carriers consider:
- Development: Auto liability claims typically develop over 12 to 36 months. Bodily injury files can grow as treatment progresses or litigation unfolds. Adjusters carry reserves for this. Underwriters consider “ultimate loss picks,” which estimate what open claims will ultimately cost, not just paid-to-date. If your paid losses look light, but open reserves are significant, the carrier will price to the expected ultimate, not the snapshot. Stability: A stable 35 to 45 percent loss ratio over multiple years is more comforting than a rollercoaster of 0 percent one year and 120 percent the next. Volatility makes pricing harder, so carriers add margin. Exposure match: If your premium last year reflected 25 units and 2 million miles, but you actually ran 3 million miles, your effective loss ratio is better than it appears. Underwriters re-benchmark to miles, revenue, or units to decide if the price was misaligned with exposure. Credibility: With a small fleet and few claims, one event can distort ratios. Actuarially, that book gets less credibility, so carriers lean more on broader class data, which can help or hurt depending on your peers.
As a rule of thumb, a carrier targeting a combined ratio under 95 to 100 percent has to load for acquisition costs, overhead, reinsurance, and profit. If your expected ultimate losses for the coming year sit at, say, $150,000, and the carrier’s expense and margin load adds another $100,000, your premium will gravitate near $250,000, adjusted for competition, capacity, and appetite.
Frequency versus severity, and why they drive different fixes
In the field, frequency problems usually come from ordinary habits: tight backing without a guide, rushed lane changes, distracted turns in urban traffic, or mirror misalignment. They are solvable with training refreshers, time buffers in routes, camera coaching, and modest investments in bumper or side underride protection. Severity problems tend to arise from speed, nighttime driving, fatigue, or high-impact events like underrides and rollovers. Solutions lean toward telematics with in-cab alerts, strict hours-of-service enforcement even when not required, more conservative speed limiters, and strategic avoidance of commercial van insurance high-risk corridors during peak hours.
Underwriters like to see that you distinguish between the two and target fixes accordingly. Telling a carrier you “implemented more training” is vague. Showing that you cross-referenced backup incidents with time-of-day and facility layout, then created a policy requiring a spotter between 5 a.m. and 8 a.m. at a particular customer yard, reads like risk management that changes outcomes.

Fault, preventability, and the gray areas
Some fleets push back hard on not-at-fault claims, and rightly so. You don’t want to pay for someone else’s mistake. But a not-at-fault crash can still be preventable from a safety standpoint. If your driver had space to increase following distance, chose a lane with frequent merges, or missed an escape path, a safety manager might call it preventable. Carriers appreciate that nuance. A safety program that tallies preventable vs non-preventable separately, then coaches to the preventable piece, typically outperforms one that treats fault as the sole measure. The fewer preventable events, the more comfortable an underwriter feels shaving margin.
Subrogation success also matters. Recovering dollars from third parties reduces ultimate losses. A pattern of quick police reports, dashcam footage preservation, and prompt tender letters improves recovery rates. If your subrogation hit rate jumps from, say, 20 percent to 40 percent after adding front and rear cameras, underwriters will notice.
The impact of claim reporting lag
A quiet killer in premiums is lag time from incident to report. Even a two to three day delay can increase costs: witnesses forget, vehicle positions change, tow yard fees accrue, and claimants get coached. Carriers track average lag days and compare them to class benchmarks. If your average is under one day, you’re a top-tier operator. That usually requires fast internal triage: a simple app for drivers to upload photos and voice notes, an after-hours call tree, and authority for a supervisor to contact the adjuster immediately. It’s tedious to build, but it directly lowers ultimate severity. In renewal talks, being able to say “our average claim lag is 0.6 days over the last 12 months” is not fluff, it’s pricing leverage.
How telematics and video change the conversation
Telematics has moved from novelty to expectation in many commercial auto segments. The question isn’t whether you have it, but how you use it. Underwriters want to see that you are not just collecting data, but closing the loop with coaching, consequences, and documented improvement.
A small delivery fleet in the southeast had a four-year run of minor at-fault crashes: mirror strikes, rear-end contacts at low speed, and parking lot nudges. They installed forward and driver-facing cameras, but the breakthrough came from changing the cadence of coaching. Weekly one-on-one reviews, five minutes each, focused on two behaviors per driver: hard braking and tailgating alerts. Over six months, hard braking events per thousand miles fell by 35 percent, and at-fault frequency dropped from nine to four incidents year over year. The carrier offered a modest premium reduction at the next renewal, not because cameras themselves are magic, but because the data translated into measurable behavior change.
Documentation matters as much as success. If you bring a one-page summary to your agent showing quarterly unsafe event rates, citations, and a before-and-after graph, you signal control. Carriers respond with credits or at least withhold surcharges.
Shock losses and the narrative that follows
Every fleet, even disciplined ones, can get hit with a catastrophic event. The response often decides what your next premium looks like. Underwriters expect a timeline: the incident facts, the immediate actions taken, root cause analysis within 30 days, and corrective measures implemented within 60 to 90 days. If the event was a fatigue-related rollover at 3 a.m., you might adjust dispatch windows, add a fatigue module to your ELD vendor, and implement a two-hour cut-off rule before dawn for certain routes. If it involved a stationary vehicle strike during pre-dawn yard moves, lighting, paint, bollards, and spotter rules will show up in your plan.
Your loss run will carry that large reserve for a while. What you can control is the perceived likelihood of recurrence. If you demonstrate that the conditions that made the loss possible no longer exist, you chip away at the risk multiplier the carrier is inclined to apply.
Contractual liability and claims that should never hit the policy
Some claims aren’t really “yours” in the economic sense, even if they show up at first. Contracts with shippers, customers, or vendors can shift liability. If you operate under a master service agreement that improperly pushes third-party property damage onto your policy, you may be paying for someone else’s risk. Underwriters can’t price around the contract itself, but they will price what they see. If your loss runs show repeated payouts for damage at a specific customer site, it’s worth revisiting indemnity and additional insured language. Tightening those terms, or adjusting your SOP at that site, may remove a recurring loss source and improve your future loss experience.
How different coverage parts react to claims history
Commercial auto often includes several coverage parts: auto liability, physical damage, motor truck cargo or hired and non-owned auto, sometimes general liability packaged alongside. Claims in one section can influence the whole account, but not uniformly.
Physical damage claims tend to be smaller and more predictable. A streak of PD losses affects your comprehensive and collision rates but may not torpedo liability if there’s no corresponding injury exposure. Conversely, multiple BI claims, even if rare, weigh heavily on liability rating. Cargo claims, especially those with spoilage due to refrigeration failure, tell a story about maintenance and driver response protocols. If your loss runs show three reefer claims in 18 months, expect questions about setpoint verification, download procedures, and dock time. Clear processes reduce frequency and can prevent a cross-coverage narrative that penalizes you in liability as well.
Hired and non-owned auto claims raise different concerns: driver vetting at the subcontractor level, certificate management, and contract indemnity. If you rely on seasonal subcontractors, your premium will reflect how tightly you manage them.
Deductibles, retentions, and skin in the game
One way to smooth the peaks and valleys in premium is to assume more risk up front. A higher physical damage deductible can trim rate, but the bigger lever sits on liability through deductibles or self-insured retentions paired with a claims handling protocol. Carriers often improve pricing when the insured takes the first $25,000 to $100,000 per occurrence, provided you have reserves, a TPA or carrier-administered program, and authority to settle. The savings should be compared to expected frequency in that layer. If you have three to five small liability claims per year, taking a $25,000 deductible can be a smart trade, but only if you build a fast settlement culture. Dragging your feet in that layer erodes savings.
For small fleets, a modest collision deductible increase may be the safest move. For mid-market accounts, a retention could make sense, especially if you have steady cash flow and a mature safety program. Run the math with your broker using your actual five-year frequency.
The role of driver quality and tenure
Underwriters read claims through the lens of driver makeup. A fleet with low tenure and high turnover usually shows more frequency. That’s not destiny, but it’s a pattern. The antidote is a rigorous onboarding process paired with mentoring and close early supervision. Some fleets use a 90-day probation with limited assignments and tighter telematics thresholds, then graduate drivers to more complex routes after performance reviews.
Backgrounds matter too. A few speeding tickets over three years is manageable, but repeated serious violations or prior at-fault crashes compound risk. If your loss runs improved after you tightened MVR standards, quantify it. For example, a distributor that raised its MVR threshold to disqualify drivers with two or more moving violations in 36 months saw a 28 percent reduction in claims frequency over the next year. Bringing that data to renewal can blunt the lingering effect of older losses.
Geography, operations, and the context of your claims
A trash hauler that works early mornings in dense urban zones will have different exposure than a regional LTL carrier running interstates. Underwriters compare you to your peer class, but context still matters. If most of your minor collisions occur at a cramped transfer station with blind corners, that’s expected exposure. Your job is to show that your rate of incidents is better than the site average or that you altered traffic flow, added convex mirrors, and trained spotters. A one-page site risk assessment with before-and-after photos carries weight.
Seasonality creates spikes. Snow months bring fender benders, heat brings blowouts. If your claims line up with predictable seasonal patterns and you have seasonal countermeasures documented, underwriters can separate the unavoidable from the preventable.
How reserves distort the picture and what you can do
Loss reserves are educated estimates that evolve. An adjuster might start a bodily injury claim at $25,000, then increase it to $90,000 after an MRI reveals a herniated disc. Your loss run shows that number even if the claim settles later for $60,000. Underwriters look at both paid and incurred, but the incurred drives the ultimate loss pick. Engage with adjusters through your broker to keep reserves aligned with facts. Provide wage records, prior medical histories if available, vehicle photos, repair invoices, and early liability evaluations. The goal isn’t to pressure for low reserves, it’s to keep them accurate. Over-reserving for months creates a shadow over your renewal.
Credible storytelling without spin
Numbers tell part of the story. Underwriters want the narrative behind them, and not marketing fluff. Here’s what a persuasive claims narrative typically includes:
- A clear table or summary of claims by type, with preventable vs non-preventable designations, before-and-after periods if you implemented changes, and lag time averages. A brief description of two or three targeted interventions, with dates and results tied to metrics, not generalities. Evidence of accountability: coaching logs, policy updates with driver acknowledgment, and if necessary, separations when performance didn’t improve. Specifics on subrogation and recovery, including how video and prompt reporting improved outcomes. A forward-looking plan for the next term, tied to exposures you anticipate changing, like new routes, added units, or a customer yard under renovation.
Most carriers won’t read a 20-page deck. Two or three pages with clean visuals, precise dates, and honest treatment of setbacks will beat a glossy brochure every time.
When to change carriers, and when to stay put
After a rough loss year, it’s tempting to shop the market. Sometimes that’s smart. A carrier with a different appetite might price your risk more favorably. But switching every year while your claims are developing can backfire. New carriers often load for uncertainty, and you may lose the benefit of a long-term loss control partnership. If your current carrier has offered resources, funded camera discounts, or provided driver training, that investment can pay off in year two or three after a spike.
The better approach is to test the market selectively. Ask your broker to sound out two or three carriers that truly like your class and geography. If there’s a big gap, explore it. If the quotes come back close, consider staying and focusing on the levers you control.
Practical moves that bend the loss curve
Some tactics have an outsized impact on how claims show up and how underwriters price them. They aren’t glamorous, but they work.
- Shorten claim reporting lag with a simple mobile workflow: a QR code in every vehicle that opens a prefilled incident form, photo prompts for vehicle positions and road conditions, and an automatic alert to the safety manager and broker. Aim for under one day average lag. Treat backing as a program, not a footnote. If 30 to 40 percent of your minor losses involve backing, enforce a “get out and look” habit, require spotters in tight yards, and tweak delivery times to reduce congestion. Track backing incidents separately and share the trendline at renewal. Use video like a shield and a scalpel. Save exoneration clips for subrogation and claim defense, but use risk flags for behavior coaching. Don’t swamp drivers with alerts. Pick two behaviors per driver per quarter and coach those. Align driver pay with safety outcomes carefully. Fleets that tie small quarterly bonuses to clean telematics scores and incident-free miles often see measurable improvement. Keep it simple and fair. If the metric feels like a black box, it backfires. Close the loop after near misses. A near miss is a free claim. If drivers can report them without fear, and you actually fix something as a result, you will see frequency drop over the next six to twelve months.
Small fleets versus large fleets: why scale changes the math
A five-truck operation lives and dies by single events. One bad crash can double the premium even if the owner does everything right. Underwriters give less credibility to thin data and lean more on class rates. The best counterweight is spotless documentation, tight hiring, and cameras. Present your last 24 months by month, not just by year, and show zeroes where they belong. That level of detail reassures underwriters.
Larger fleets get judged more on trends and ratios per million miles. A bad quarter hurts less, but repeated themes hurt more. These fleets can leverage retentions, analytics, and loss control partnerships to capture underwriting credits. The challenge is consistency across terminals. A cluster of claims at a single hub can drag the whole account. Underwriters will ask if you can isolate that location in your internal reporting and apply targeted fixes.
Where pricing goes after a clean stretch
If you had a rough year followed by 18 to 24 months of calm, expect a lag before prices fully reflect the improvement. Carriers like to see durability. The second quiet year typically unlocks better credits and sometimes a change in pricing tiers. If the line is profitable for the carrier overall and reinsurance costs haven’t spiked, you have a tailwind. If the market is hard, even good loss experience might only mitigate increases rather than produce cuts. Your leverage is highest when you can demonstrate sustained behavior change tied to claims.
Final thoughts from the field
Claims history is not destiny, but it is a loud signal. Underwriters use it because it works on average across large pools of risk. Your job is to make sure your individual story stands out from the pool. That means getting beyond generic safety talk and into measurable actions: faster reporting, smarter coaching, targeted fixes at high-loss nodes, honest preventability reviews, and clean documentation. When you pair that with a broker who can translate your operational improvements into underwriting language, you can move a premium from “loaded for uncertainty” to “priced for control.”
The payoff is not only the rate. Fewer accidents mean less downtime, better driver morale, and stronger relationships with customers who value reliability. Those benefits usually arrive before the premium drop shows up on the invoice. If you keep stacking them, the invoice eventually catches up.
