I’ll spare you the fluff. If you want to run legally and win better freight, you need the right commercial truck insurance, the right filings, and proof on demand. Here’s the straight talk I give new authorities, leased owner-operators, and growing fleets.

What Insurance Is Legally Required for a Commercial Truck?

Primary liability at federal minimums if you operate in interstate commerce under your own authority. States can add intrastate twists (extra filings, limits, or forms). Cargo is only federally mandatory for household-goods carriers, but most shippers and brokers require it anyway.

When must coverage be in place?

Before FMCSA grants operating authority, when you add units/drivers, and any time your risk profile changes (new commodities, lanes, or radius). I treat coverage activation and filings as a single workflow—because if the filing lags, you’re effectively grounded.

Federal Commercial Truck Insurance Requirements

Primary Liability (BIPD): Bodily Injury & Property Damage that protects the public—this is the one that gets your authority turned on. Typical federal minimums most carriers know by heart:

• $750,000 for most for-hire carriers hauling non-hazmat ≥10,001 lbs GVWR.

• $1,000,000 or more is standard in contracts even when the federal floor is $750k (many shippers/brokers demand it).

• Up to $5,000,000 for certain hazardous materials (explosives, inhalation hazards, radioactive, etc.).

Cargo insurance: Federally required only for household-goods carriers in interstate commerce. Everyone else: cargo is contractual/market-driven but practically essential.

If your contracts require higher limits than the federal minimums, your filings can still reflect your policy’s actual limit; don’t run a policy that can’t satisfy your biggest customer’s COI demands.

Commercial Truck Insurance Requirements for a New Owner-Operator

Starting your own authority? Do these in order; skipping steps costs weeks:

1. Quote & bind primary liability (and cargo or PD as needed).

2. File proof with FMCSA via your insurer:

   • BMC-91/91X (liability),

   • MCS-90 endorsement (responsibility confirmation),

   • Surety or financial responsibility forms if applicable (BMC-84/85 are for broker bonds, included here only if you wear that hat).

3. BOC-3 (process agent) filing—no BOC-3, no authority.

4. Get on the portal (Login.gov). Your e-filers or your agent should push filings fast and confirm postings.

5. COI (Certificate of Insurance) templates ready for brokers or shippers: list commodities, radius, equipment, and special endorsements (reefer breakdown, trailer interchange, etc.).

Our Simplex point of view; first-year new-authority delays usually come from an MCS-90 mismatch, missing BOC-3, or quoting wrong commodities or radius. We run a “pre-filing huddle” so the carrier, underwriter, and filings desk agree before anyone pushes “submit.”

Owner-Operator Insurance vs. Motor Carrier Insurance: Key Differences

Leased to a motor carrier:

• The carrier typically provides primary liability while you’re under dispatch.

• You (the driver or the owner) often carry Non-Trucking Liability (NTL) or Bobtail, Physical Damage (for your tractor), and sometimes Occupational Accident if you’re not on the carrier’s WC.

• Trailer Interchange may be required if you pull non-owned trailers under interchange agreements.

Running under your own authority:

• You buy primary liability and manage filings.

• You choose cargo limits by commodity and contracts, add physical damage, consider general liability, reefer breakdown, and hired/non-owned auto if needed.

State-Specific Trucking Insurance Laws

States may require their own forms or minimums for intrastate operations (sometimes lower than federal; sometimes just different proof).

How I verify fast:

• State DOT or PUC websites

• Your insurer’s state filings desk

• A quick COI test against your largest intrastate customer’s contract.

I keep a one-pager per state in the client file; if we add a terminal or change garaging, we re-check that one-pager before renewal.

What Is Primary Liability and Cargo Insurance for Truckers?

• Primary Liability (BIPD): Pays third-party injury/property damage. It does not pay to fix your truck. Set limits to match contracts and realistic loss scenarios on your lanes.

• Cargo: Pays for the commodity you haul (perils depend on form). Watch sub-limits and exclusions: theft limits, temperature change (reefer), unattended vehicle, and high-theft classes (electronics, pharma). A $100k cargo limit is common, but car-haul, high-value freight, or heavy equipment often demand more

Documents Needed to Apply for Commercial Truck Insurance

• Corporate: LLC/Corp papers, FEIN, addresses/garaging.

• Drivers: Full roster with MVRs, years CDL, prior experience, violations.

• Equipment: Year, make, model, VINs, stated values (for PD), safety features.

• Operations: Commodities, lanes/radius, estimated miles, safety program.

• History: Loss runs (if any), prior insurance, citations/audits.

• Extras that speed underwriting: Maintenance logs, driver handbook, securement SOPs, camera/telematics policy, shipper contract requirements (so we match COIs first try).

Legal minimums get your authority active; smart limits and clean paperwork get you freight and keep you in business. I’ve been in trucking insurance and compliance for more than 20 years, and the playbook that works is simple: set the right structure on day one, verify filings, and do a disciplined annual review. We’re a one-stop shop (insurance, DOT compliance, permitting, factoring, freight planning), and we don’t leave stones unturned—because a missing filing or a stale COI can cost far more than any premium credit you ever saved.
