Insurance Curator Choosing the right policy limits for a trucking fleet in the United States is a balancing act: enough coverage to protect your business, drivers and shippers — but not so much that you overpay on premiums. This guide explains practical limit choices, the cost trade-offs, common endorsements and exclusions that change your protection, and proven strategies fleets in hubs like Houston, TX and Los Angeles, CA use to control insurance spend while keeping adequate coverage.
Why limits matter (and what “limit” really means)
- Policy limit = the insurer’s maximum payment for a covered loss (per occurrence or aggregate).
- Insufficient limits can mean out-of-pocket exposure after a major loss, legal judgments, or contractual penalties from shippers/ brokers.
- Excess or umbrella policies supplement primary policy limits but cost more; their structure matters (see comparison below).
For regulatory context and the role of the MCS-90 endorsement in demonstrating financial responsibility, see the FMCSA’s MCS-90 overview: https://www.fmcsa.dot.gov/regulations/mcs-90-endorsement.
Typical limit choices and commercial context
Common primary liability limits for interstate trucking fleets:
- $1,000,000 (1M) — Market standard for many regional and non-hazardous freight operations.
- $2,000,000 (2M) — Common for higher-value loads or carriers with tighter shipper contracts.
- $5,000,000 (5M) and up — Often required for hazardous materials, high-value freight, or customers that insist on higher limits.
Cargo limits and physical damage limits are separate and must be sized to typical payload values and replacement costs for tractors/trailers.
Typical premium impact by limit (real-world estimates)
Premiums vary by geography, driver records, fleet size, commodity, and claims history. Below are typical market examples for long‑haul interstate power units (per power unit, annual) to illustrate trade-offs. These ranges are drawn from market pricing patterns reported by major commercial insurers and brokers (see Progressive and Insureon for comparative quotes and ranges).
| Primary Liability Limit | Houston, TX (est. annual / power unit) | Los Angeles, CA (est. annual / power unit) | Typical % increase vs $1M |
|---|---|---|---|
| $1,000,000 | $10,000 | $13,000 | baseline |
| $2,000,000 | $12,000 | $15,600 | +20% |
| $5,000,000 | $16,000 | $20,800 | +60% |

How to decide the right limit for your fleet (practical steps)
- Inventory your maximum exposure
- Average and maximum cargo value per load.
- Tractor and trailer replacement costs.
- Typical route and population density (urban L.A. vs rural Texas highways).
- Review contract and broker requirements
- Many brokers/shippers require carriers to carry specific limits (sometimes 2M or 5M). Negotiate when possible.
- Confirm whether those requirements are for primary limits or whether an umbrella/excess will satisfy them.
- Model worst‑case liability scenarios
- Use defensive estimates for BI/PD, legal defense, and punitive damages in your operating states.
- Evaluate loss history
- Fleets with frequent minor claims may benefit from higher limits and better risk control, while low-loss fleets can prioritize cost savings.
- Get scored quotes for multiple limit scenarios
- Compare the marginal premium increase to the additional coverage. Often, the jump from $1M to $2M is modest; $2M to $5M can be disproportionately expensive.
- Consider umbrella/excess vs raising primary
- Umbrellas are typically cheaper per dollar of limit, but coverage gaps or underlying exclusions can cause problems (see Umbrella vs Excess discussion below and internal guide).
Endorsements and exclusions that change your effective limits
Endorsements and exclusions materially affect how limits apply. Common items to evaluate:
- MCS-90 endorsement — Ensures public liability coverage meets FMCSA requirements. See FMCSA: https://www.fmcsa.dot.gov/regulations/mcs-90-endorsement.
- Cargo endorsements — Limit cargo coverage by commodity, route, or per-shipment; consider contingent cargo endorsements if needed.
- Non-Trucking Liability / Bobtail — Coverage while the truck is being used off-duty; crucial for owner‑operators.
- Named Insured / Additional Insured / Waiver of Subrogation — These change who’s covered and how recoveries work; see internal guides for operational impact.

Cost-control levers that preserve protection
- Higher deductibles on physical damage reduce premiums — common choices: $1,000–$5,000.
- Split limits and per-accident aggregates — Understand if your policy has aggregate limits that can be exhausted.
- Loss control programs — Safety technology (ELDs, collision mitigation), driver training, and robust hiring can reduce premiums materially.
- Claims management and subrogation — Aggressive recovery from responsible third parties preserves loss history.
- Layering with umbrella/excess — Often cheaper than increasing the primary policy to very high dollar limits; ensure the umbrella doesn’t have narrower coverage than the primary.

Example buying strategies by fleet profile
- Short-haul regional refrigerated fleet (Midwest/ Texas routes)
- Typical choice: $1M primary, $2M umbrella. Higher cargo limits for refrigerated loads; $25K–$100K cargo per trailer. Use higher deductibles on physical damage.
- Long-haul interstate dry-van fleet (Los Angeles ↔ Chicago lanes)
- Typical choice: $2M primary (if broker requires), $3M–$5M umbrella. Expect 10–30% higher premiums for CA-based operations due to frequency and severity of claims.
- Hazmat or high-value freight
- Typical choice: $5M+ primary or layered excess to meet shipper contracts. Cargo insurance rated per $1,000 of declared value; consider contingent cargo endorsements and broker liability protections.
Red flags to avoid
- Accepting lower limits to win business without verifying that limits satisfy shippers’ contracts.
- Buying a cheap umbrella that contains more exclusions than the primary policy.
- Ignoring audit provisions that can increase premiums retroactively if payroll/vehicle counts were misreported (see audit guidance: https://insurancecurator.com/audit-guide-reviewing-policy-wordings-to-plug-gaps-without-overpaying-for-trucking-insurance/).
Next steps to get the right coverage (practical checklist)
- Inventory exposures (cargo value, vehicle replacement, routes).
- Obtain market quotes for at least three limit scenarios ($1M, $2M, $5M).
- Ask carriers to demonstrate how umbrella/excess layers attach and what exclusions apply.
- Confirm contract wording with shippers/brokers (additional insured, waiver of subrogation).
- Implement loss-control measures to lower future renewal premiums.

Accurate quotes will depend on fleet specifics, state filing differences, and insurer appetite. Start with tailored proposals from specialty trucking insurers (examples: Progressive Commercial, Great West Casualty, and national brokers) and compare the marginal premium for each increment of limit before deciding.
