Why Fleet Insurance Premiums Keep Rising and What Insurers Want

Where driver training fits in a renewal file

Training only helps at renewal if it connects to your real losses and leaves a record. Here is the chain an underwriter can follow.

1. Training needYour loss runs show where crashes happen, such as backing, rear-end hits or intersections.
2. PracticeDrivers rehearse those exact situations in a simulator, where a mistake costs nothing.
3. Instructor reviewA trainer reviews each session and coaches the habit behind the error.
4. FitLessons and hardware match your vehicles, your drivers and the space you have.
5. Evidence and limitsRecords show who trained, on what, and what changed. Scores are not crash outcomes.
6. Next stepRun a pilot early enough to show a trend before your renewal date.

In our Advanced Driver Safety (ADS) program, lessons cover hazard detection, following distance, space management, intersections, distracted driving, backing, residential delivery and trailers. Our Vantage reporting tracks reaction time, awareness and decision-making for each driver, so a safety manager can spot high-risk drivers early. Fleets choose Desktop Series or Full Cab Series hardware. The Advanced Driver Safety lesson list and Vantage reporting details show whether your most common incident types have a matching lesson. Check that before you plan anything else.

Our ADS FAQ puts it this way: consistent training records, performance data and documented incident reduction are the strongest factors in negotiating lower premiums. That is our view from working with fleets. It is not an insurer rating rule. Our customer results are older and self-reported. A UPS division manager reported a 38% drop in crashes after his facility added our earlier Virtual HD program in July 2013. Treat that as one fleet's experience, not a forecast for yours. Simulation adds to road training and coaching. It does not replace them.

Why commercial auto premiums keep rising

The plain reason is that insurers pay out more than they collect on this line. AM Best reported 14 straight years of underwriting losses in commercial auto, including a $4.9 billion loss in 2024, in its September 2025 segment report. Its newer data showed another $1.9 billion underwriting loss in 2025, according to Claims Journal. The losses sit in liability. Physical damage coverage is still profitable.

When a line loses money for years, carriers raise rates, cut capacity or both. By the end of 2025, commercial auto had seen 58 straight quarters of premium increases in the CIAB survey. The increases are getting smaller, but they have not stopped.

Large brokers see the same pattern. Marsh's index for Q2 2026 showed US casualty rates up 7%, with double-digit auto liability increases common, even as the overall US rate fell 2% (Marsh Global Insurance Market Index).

Three cost drivers behind the rate

Lawsuits cost more. A Triple-I and Casualty Actuarial Society study estimated that legal system abuse added $52.0 billion to $70.8 billion to commercial auto losses over the past decade. That is roughly a quarter to a third of booked losses. This is an industry estimate, not a measure of your claims, but it explains why one serious crash can now reset a fleet's price.

Repairs cost more. Motor vehicle repair prices rose 5.8% in the 12 months ending September 2026, against 3.7% for all items (BLS Consumer Price Index). Sensors make it worse. In AAA's tests on passenger vehicles, driver-assist systems made up 37.6% of repair cost on average (AAA, Cost of ADAS Repair, 2023).

Crashes cost you more than the premium. The Network of Employers for Traffic Safety puts the average on-the-job crash at nearly $56,000 to the employer (NETS, 2026). For trucking, ATRI found liability and cargo premiums averaged $0.11 per mile in 2025, up 3.9% from 2024 (FleetOwner on ATRI's 2026 cost report).

For a CFO, the market trend sets the floor. Your own file decides where you land above it.

How underwriters price your fleet

Underwriters start with the exposure: how many vehicles, what size, how far they travel and what they do. Rating classes for trucks sort by weight, business use and radius, such as local work within 50 miles versus long haul over 200 (Commercial Automobile Insurance Manual, 2026). You can't change much here quickly. You can make sure your vehicle list and use are accurate, since a mismatch between the policy and real operations is a red flag.

Loss history comes first

Your loss runs list each claim with dates, amounts paid and money still held in reserve. Underwriters read them for frequency (how often) and severity (how big). A string of small backing claims says something different from one large injury claim. They also check the gap between the crash date and the report date. Late reporting can mean tighter terms or higher premiums, according to Risk Placement Services, and Hub International recommends reporting within 24 hours.

Then they look at how you manage drivers

Hub International names five areas underwriters focus on: compliance, accident management, driver management including ongoing training, vehicle management, and documentation (Hub, June 2026). In practice that means:

• A written standard for who can drive, checked with motor vehicle records. FMCSA-regulated carriers must review each driver's record at least once every 12 months (49 CFR 391.25).
• For regulated carriers, CSA scores, which draw on 24 months of inspection and crash data.
• A written fleet safety program that existed before the last crash.
• Proof that you act on data, not just collect it.

That last point is where renewals are moving. One fleet risk leader told Automotive Fleet that underwriters now ask about cameras, "What are you doing with it?" Hub says underwriters want to see a trend that moves consistently over time, with coaching documented for flagged events (Hub, September 2026).

What to put in your renewal submission

We built this checklist from published insurer and broker guidance. It is advice, not an underwriting rule. Your broker can tell you what your market expects.

What training records can and can't do for your premium

Here is the honest version. We reviewed guidance from Travelers, Hub, Amerisure and Progressive and found no published, fixed premium credit for driver training. Training shows up as one part of how underwriters judge driver management.

Insurers do price data they can verify. Progressive's Smart Haul program gives for-hire truck policies at least a 5% discount for sharing data from a preferred electronic logging device, and re-rates at renewal (Progressive Commercial). That is telematics, not training. It does show the direction: proof beats promises.

The research on training points the same way. ATRI found that simulator-trained new truck drivers were safer in their first six months, but the benefit faded by 12 months (Transport Topics, 2014). A Virginia Tech study for FMCSA found that onboard monitoring paired with manager coaching cut safety events per mile by 37% and 52% at two carriers (Hickman, Hanowski and Ajayi, 2009). One-time training fades. A loop of data, practice, coaching and re-checking holds up better, and it produces the trend line underwriters ask for.

So the records worth keeping are specific. Log the date, driver, lesson, result, coach's notes and follow-up for each session. Tie each lesson to an incident type from your loss runs. A stack of certificates says drivers sat through something. A linked record says you found a problem, worked on it and checked the result.

A 90-day plan before your next renewal

This plan is our advice for fleets with a renewal three months or more away. Adjust it with your broker.

1. Days 1 to 15Pull at least three years of loss runs. Sort claims by type, cost and reporting lag. Find your top two incident types.
2. Days 15 to 30Set or refresh your driving record standard and safety policy. Decide which drivers need targeted work first.
3. Days 30 to 75Run targeted practice and coaching on those incident types. Log every session. Act on camera or telematics alerts and note what you did.
4. Days 75 to 90Build a one-page summary with the trend, the actions and the records. Meet your broker well before the renewal, not 60 days out.

Hub International notes that many fleets only contact underwriters about 60 days before renewal (TheTrucker.com, July 2026). Starting earlier gives you time to show change, not just describe it. For more on treating drivers as the managed asset, read fleet management: the cars or the drivers?
