Trucking insurance in 2026 — nuclear verdicts hardened the market. Here's who's actually writing.
Trucking insurance hardened materially between 2018 and 2024 — driven by nuclear verdicts in trucking-accident litigation. Here's who's still writing you in 2026, depending on how many trucks you run.
The short answer
- 1 truck (owner-operator), clean record — Quote Progressive Commercial first. They write the most US owner-operators by volume and the buying flow is direct.
- 2-20 trucks (small fleet) — Quote Great West Casualty first. Deep small-fleet specialty book. Also worth quoting: Sentry, Northland (Travelers), Old Republic.
- 20-100 trucks (mid-fleet) — The broker matters more than the carrier. Find a trucking specialist (Reliance Partners, Northstar Insurance, Anderson Trucking) before you talk to any carrier.
- 100+ trucks (large fleet) — Marsh, Aon, or Willis Towers Watson trucking practice. You're structuring a layered program with captive insurance options, not buying a single policy.
The rest of this essay covers what actually drives your cost over time and the traps to avoid. Specific premium ranges vary widely by fleet, drivers, equipment, geography, and prior claims — get quotes.
Why the market hardened
Three things happened simultaneously between 2018 and 2024:
1. Nuclear verdicts went mainstream. Trial-lawyer specialization in trucking accidents pushed jury awards into eight and nine figures more frequently. ATRI has published research on the nuclear-verdict trend; it remains a leading driver of commercial-auto loss-cost growth.
2. Carriers exited or restricted. Several markets reduced appetite or repriced surplus-lines capacity. By 2023, owner-operators in some metros struggled to get a standard market quote.
3. CSA scores became make-or-break. FMCSA's Compliance, Safety, Accountability score is now a primary underwriting input — fleets with poor CSA percentiles face restricted appetite or non-renewal at most standard markets.
The market has softened modestly in 2025-2026 as new capacity entered, but the new baseline is permanently higher than pre-2018.
More on the carrier picks
Owner-operator (1 truck, clean MVR, 3+ years CDL). Progressive Commercial writes the largest US owner-operator book by volume. Their direct-to-driver online flow doesn't require a broker. If Progressive declines (uncommon for clean drivers), try Great West Casualty, then Sentry.
Small fleet (5-20 trucks). Great West Casualty has been a small-fleet specialty for decades. Their underwriting team understands fleet operations more deeply than generic commercial-auto carriers. Alternative quotes: Sentry, Northland (Travelers), Old Republic.
Mid-fleet (20-100 trucks). At this size you need a layered insurance program — primary auto liability + excess limits, plus cargo, GL, and workers comp coordinated. A trucking-specialty broker (Reliance Partners, Northstar Insurance, Anderson Trucking, Insurance Office of America) knows which underwriters to call. A generalist commercial broker will usually quote you wider markets that don't have your specific appetite.
Large fleet (100+ trucks). Captive insurance, self-insured retention, and excess programs need consulting-level structuring. Marsh, Aon, or Willis Towers Watson trucking practice.
The four decisions that actually matter
Everything else is noise. The four things that drive trucking-insurance cost over time:
1. Driver hiring discipline. One DUI in the last 5 years or a driver with under 2 years CDL experience materially increases your loss probability. Most carriers want "3+ years CDL, no DUIs ever, no preventable accidents in 3 years, clean MVR." Hire below that bar deliberately, not accidentally.
2. CSA score management. Your percentile rank across BASICs (Unsafe Driving, HOS Compliance, Vehicle Maintenance, etc.) compounds. Each annual renewal reads your trailing-24-month CSA. Active management — ELD-enforced HOS compliance, regular DVIR enforcement, driver coaching — meaningfully reduces premium over time.
3. Equipment age. Trucks under 5 years old with modern safety features (collision-mitigation, lane-departure, electronic stability control) typically carry lower premium than older equipment. The equipment-replacement breakeven varies, but carriers reward newer fleets directly.
4. Deductible selection. Most fleets are over-insured on small claims and under-insured on large. If you can self-fund a meaningful chunk of physical-damage claims, taking higher deductibles typically reduces premium. Run the math with your broker; the breakeven is usually favorable above a few trucks but depends on your loss history.
What "best" means depends on what you're optimizing
Three priorities, three different answers:
| Priority | Pick |
|---|---|
| Lowest total cost over 5 years | Great West (small fleet) or Progressive (owner-op), aggressive deductibles, aggressive CSA management |
| Lightest operational lift | Progressive Commercial — their flow is the most automated in the industry |
| Maximum coverage breadth, custom program | Marsh or Aon trucking practice, layered program with captive or SIR |
Most operators want #1 but ask for quotes optimizing for #3 by default. That's why their rates feel high.
The trap to avoid: cheap MGAs
Several trucking MGAs in 2024-2026 quoted well below market. Some of these MGAs were reinsured weakly, paid slowly on claims, or were eventually non-renewed by their reinsurers — leaving operators without coverage mid-policy.
Test before binding: ask the MGA for (1) their AM Best rating, (2) the rating of their primary reinsurer, (3) their parent company. If any answer is evasive, walk away.
What's likely to change in 2026-2027
- Capacity continues to enter; pricing may soften modestly if claim frequency stays flat.
- CSA score weighting in underwriting increases, not decreases.
- Telematics-based premium credits (Lytx, Samsara, CMT integration) become table stakes — fleets without telematics face a structural rate disadvantage.
If you're considering a multi-year deal in 2026, renew annually instead. The market direction in trucking is too uncertain to lock in.

Frequently asked
Should I just go with Progressive Commercial?
If you're an owner-operator with a clean MVR, yes — Progressive should be your default. If you're a small fleet, Progressive is still credible but Great West Casualty usually has deeper fleet underwriting. Above 20 trucks, Progressive's direct flow stops being competitive against properly-brokered programs.
How much does CSA score actually move premium?
Materially. Fleets above the 75th percentile in a major BASIC (Unsafe Driving, Vehicle Maintenance) face surcharges or restricted carrier appetite. Above 90th percentile, most standard markets non-renew automatically. Active CSA management is usually the highest-ROI cost lever — exact savings vary by fleet, but it's typically the biggest controllable factor.
Are MGAs quoting cheaper rates worth taking?
Sometimes — but verify the MGA's reinsurance backing and AM Best ratings before binding. Several MGAs in 2024-2026 offered below-market rates that the reinsurance market eventually corrected. Some operators ended up mid-term non-renewed when the reinsurer pulled out. If an MGA can't tell you their reinsurer or it's an unrated carrier, walk away.
When does captive insurance start to make sense?
Once your annual premium spend is substantial and your operations are stable enough that you can predict your loss costs. Captive setup and management costs are meaningful, so below a certain scale they eat the savings. Marsh Captive Solutions and Aon Captive & Insurance Management are the typical advisors to talk to about whether your specific operation qualifies.
