Motor carrier insurance in Texas and the filings behind it

Whose name is on the motor carrier authority

A motor carrier is the business responsible for the truck, the driver, and the load under its own operating authority. If your name sits on the USDOT number and the authority, the liability is yours, whether you run one truck or forty.

For-hire carriers haul other people's freight for pay. Private carriers haul their own goods, like a building supply company delivering its own lumber to job sites.

Both need insurance. For-hire interstate carriers carry extra filing duties with FMCSA, and Texas intrastate carriers, for-hire or private, file with TxDMV once their vehicles cross the weight or cargo thresholds.

Two businesses get confused with carriers. A freight broker arranges loads but does not haul them, so it files its own financial security instead of truck insurance.

A dispatch service that books loads for you is not a motor carrier either, and its paperwork never replaces yours. If you run trucks and also broker overflow loads, tell the agent, since contingent cargo and contingent auto liability may come into play.

Private carriers get caught off guard here. A Texas supply company running a truck over 26,000 lbs on its own deliveries still needs a USDOT number, TxDMV authority, and a Form E on file, even though it never hauls a load for anyone else.

Form E, BMC-91X, and the rest of the filing stack

Here is how it works. Your insurer proves your coverage to regulators through electronic filings, and the regulator watches those filings, not your declarations page. Each row below is a separate duty with its own owner.

The contract row is the only one no regulator enforces, and it is the one that decides whether a broker tenders you a load.

Why the MCS-90 is not your coverage

The MCS-90 endorsement rides along with the interstate filing. It guarantees payment to the public up to the federal minimum, even when the policy itself would not cover the claim.

The catch: the carrier has to pay the insurer back for those claims. The MCS-90 protects the public, not your business.

Auto liability is the heart of a motor carrier policy. It pays for bodily injury and property damage you cause to others while operating, plus your legal defense. Cargo, physical damage, general liability, and trailer interchange usually sit beside it, packaged together or placed with separate insurers.

The MCS-90 tends to show up in exactly the claims a carrier did not expect: a driver not listed on the policy, a truck missing from the schedule on a scheduled-auto form, a commodity you did not declare, or a trip outside your stated radius. Cargo forms often exclude unattended vehicle theft, reefer breakdown unless endorsed, and certain high-theft goods.

Liability forms carry a pollution exclusion unless you add broader coverage. Read the declarations and endorsements, not just the quote summary.

How underwriters read a carrier's operation

Underwriters price a motor carrier on the operation as a whole, not truck by truck. They look at the company much the way a DOT auditor would.

Send the agent your USDOT, MC, and TxDMV numbers, the driver list with recent MVRs, unit VINs and garaging ZIPs, your lanes with a rough commodity mix, loss runs, and any broker requirements you have to meet. A file with holes in it reaches fewer markets, and that rarely makes it cheaper.

• Years under your authority and any prior authority history
• Driver experience and MVRs, with two or more years of CDL experience as a common cutoff
• Commodities, radius, and the states or Texas regions you run
• CSA scores, roadside inspection results, and any audit history
• Loss runs, the limits you choose, and your deductibles
• Garaging ZIP codes and unit values
