Starting or running a trucking company in Dallas means dealing with two different sets of insurance rules: state rules for trucks that stay inside Texas, and federal rules for trucks that cross state lines. Confusing the two is one of the most common — and most expensive — compliance mistakes a carrier can make. Here is how the two systems differ, and which filings your insurance company needs to make on your behalf.

Is “DOT Insurance” the Same as FMCSA Insurance?

Not quite, and the difference trips up a lot of new carriers. There is no insurance product called “DOT insurance.” What people usually mean is the commercial auto liability coverage — and the filings that go with it — that a regulator requires before you can legally operate for hire. Which regulator sets the number depends on where you run.

It also helps to separate three things that often get lumped together. A USDOT Number is an identifier used for safety tracking. Operating authority — an MC number federally, or a TxDMV Number in Texas — is permission to haul for compensation. Insurance is what you must carry and, in most cases, prove through a filing before that authority becomes active. Plenty of carriers have a USDOT Number and still cannot legally run, because the insurance filing was never made.

Who Regulates What?

Intrastate trucking — operating only within Texas — is regulated at the state level. Motor carrier registration and insurance filings for intrastate operations are handled by the Texas Department of Motor Vehicles (TxDMV), Motor Carrier Division. Many truckers still say “Texas DOT number,” but the credential is actually a TxDMV Number issued by TxDMV.

Interstate trucking — crossing state lines, or hauling loads that originate or are delivered out of state — is regulated by the Federal Motor Carrier Safety Administration (FMCSA).

If your business does both, you need to comply with both sets of rules and carry the higher of the applicable insurance limits.

Texas Intrastate Insurance Requirements (TxDMV)

Not every Texas truck needs a TxDMV registration. You are required to register for intrastate operations if you operate any of the following:

Vehicles with a gross weight, registered weight or gross vehicle weight rating over 26,000 pounds
Vehicles hauling hazardous materials in quantities that require placards
Farm vehicles with a gross vehicle weight rating of 48,000 pounds or more
Vehicles designed to transport 16 or more passengers, including the driver
Commercial school buses
Household goods transported for compensation, at any weight

Carriers registered under the Unified Carrier Registration program that operate only in interstate or international commerce are not required to register with TxDMV.

Once you are registered, the minimum liability limits that apply depend on what you haul and how much the vehicle weighs:

$500,000 for most private and for-hire carriers operating vehicles over 26,000 pounds
$300,000 for household goods carriers operating vehicles under 26,000 pounds
$1,000,000 or $5,000,000 for oil and hazardous materials, following the federal schedule
Household goods carriers also need cargo coverage of $5,000 per vehicle and $10,000 aggregate
$500,000 for commercial school buses and buses seating 16 to 25 passengers, excluding the driver
$5,000,000 for buses seating 26 or more passengers, excluding the driver

Form E is the proof-of-liability-insurance filing your insurance company submits electronically to TxDMV. Household goods carriers additionally need Forms H and I, which prove cargo insurance. Once your insurer files the Form E and all fees are paid, TxDMV activates your TxDMV Number.

If the policy is cancelled or expires, your insurer files a Form K. Your policy has to require the insurer to give TxDMV electronic notice at least 30 days before that happens, so a lapse is never silent.

FMCSA Insurance Requirements (Interstate)

Two Federal Rules, Two Different Proofs

Federal requirements come from two different parts of the same regulation, and they are proved in two different ways. Most for-hire carriers are subject to both.

Safety-side financial responsibility (49 CFR Part 387, Subpart A) applies to for-hire and private carriers running vehicles rated 10,001 pounds or more in interstate commerce. It is proved by the MCS-90 endorsement attached to your policy. Nothing is filed with FMCSA.
Registration-side security (49 CFR Part 387, Subpart C) applies to for-hire carriers that need operating authority. It is proved by a BMC-91 or BMC-91X certificate that your insurance company files directly with FMCSA.

That distinction matters when you compare numbers. The $750,000 figure appears in both rules, but the $300,000 minimum for the smallest vehicles comes from the registration rule, not the safety rule.

If you haul across state lines, or your loads originate or terminate out of state, FMCSA’s minimum levels of financial responsibility apply. For property carriers these currently include:

$750,000 for general (non-hazardous) freight in vehicles rated 10,001 pounds or more
$300,000 for non-hazardous freight in vehicles rated under 10,001 pounds
$1,000,000 for oil and certain hazardous materials
$5,000,000 for the highest-risk hazardous materials, such as explosives or bulk poison gas

If you carry passengers rather than freight, a separate federal schedule applies: $5,000,000 for vehicles designed to seat 16 or more passengers, and $1,500,000 for vehicles seating 15 or fewer. Passenger carriers use the MCS-90B endorsement in place of the MCS-90.

Cargo insurance is not federally required for most property carriers — but it is required for household goods carriers, and in practice most brokers and shippers will not tender loads without it.

The key federal filings and endorsements are:

BMC-91 or BMC-91X — certificates of insurance that your insurance company files directly with FMCSA as proof of public liability coverage. (The BMC-91X version is used when coverage is written for specific limits or layered across more than one policy.)
MCS-90 — an endorsement attached to your liability policy itself. It is not filed with FMCSA; it stays with your policy as proof of financial responsibility.
MC Number (operating authority) — FMCSA will not grant operating authority until the required proof of insurance is on file.

Side by Side: Texas Intrastate vs. Federal Interstate

The same truck can be subject to one set of rules or both, depending on where the load goes. Here is how the two systems line up.

	Texas intrastate (TxDMV)	Federal interstate (FMCSA)
Who it applies to	Carriers operating only inside Texas	Carriers crossing state lines, or hauling loads that originate or end out of state
Credential	TxDMV Number	USDOT Number plus MC operating authority
Common liability minimum	$500,000 for vehicles over 26,000 pounds	$750,000 for general freight at 10,001 pounds or more
Liability filing	Form E, filed by your insurer	BMC-91 or BMC-91X, filed by your insurer
Policy endorsement	Not applicable	MCS-90 (MCS-90B for passenger carriers)
Cargo insurance	Required for household goods carriers — Forms H and I	Required for household goods carriers — BMC-34 or BMC-83
Cancellation notice	Form K, at least 30 days to TxDMV	30 days to FMCSA for filings; 35 days for the MCS-90 endorsement

What If You Operate Both In and Out of Texas?

Many Dallas-based carriers haul both locally and across state lines. In that case you will generally need to meet the higher federal limits, keep both your FMCSA filings (BMC-91/91X) and your TxDMV filing (Form E) current, and make sure the name and address on your filings match your authority records exactly. Gaps or mismatches can delay authority approvals, trigger fines, or take you off the road.

What Insurance Do You Need for an MC Number?

An MC number is operating authority, and FMCSA will not activate it on the strength of a policy alone. Your insurance company has to file proof on your behalf. For a typical for-hire property carrier that means:

Public liability at the limit that matches your vehicles and commodities, filed on a BMC-91 or BMC-91X
Cargo insurance on a BMC-34 or BMC-83, if you are a household goods carrier
A BOC-3 designation of process agents — not insurance, but a separate filing FMCSA requires before authority is granted

Buying the policy and filing it are two different steps, and the second one is what holds up authority. Applications are published in the FMCSA Register, and an application left without its required filings can be dismissed. If you are activating a first authority, our New Venture Trucking program exists to get these filings placed correctly the first time, alongside the commercial truck insurance the filings are based on.

What Happens If Your Insurance Lapses or Is Cancelled?

Coverage that is cancelled, non-renewed, or simply never re-filed is one of the fastest ways to lose operating authority. Both regulators are notified by the insurer directly, so a lapse is never quiet.

Federally, a filing cannot be cancelled until 30 days after written notice is filed with FMCSA. The MCS-90 endorsement carries its own 35-day notice requirement.
If a replacement filing is made, the outgoing insurer’s obligation ends on the replacement’s effective date — so switching carriers properly leaves no gap.
In Texas, the insurer files a Form K, and your policy must require at least 30 days’ electronic notice to TxDMV before cancellation or expiration.

Missing a required filing or carrying the wrong limits can result in fines and citations, vehicle impoundment, administrative penalties, and suspension or revocation of your operating authority. It can also delay activation of a DOT, MC, or TxDMV number that is still pending. You remain responsible for keeping coverage on file even while you are parked, between loads, or waiting on a renewal notice that never arrived.

Frequently Asked Questions

How much insurance does FMCSA require?

For general freight in vehicles rated 10,001 pounds or more, the federal minimum is $750,000 in public liability. It rises to $1,000,000 for most regulated hazardous materials and $5,000,000 for the highest-risk loads. Non-hazardous property in vehicles rated under 10,001 pounds carries a $300,000 minimum under the registration rule. In practice, many brokers and shippers require $1,000,000 regardless of the federal floor.

Is DOT insurance the same as FMCSA insurance?

“DOT insurance” is an informal term, not a product. For interstate carriers it usually means the liability coverage and filings FMCSA requires. In Texas it may instead mean what TxDMV requires for intrastate operations, since many truckers still say “Texas DOT number” for what is now a TxDMV Number. Always ask which regulator someone means before you act on a limit.

Does FMCSA require cargo insurance?

Only for household goods carriers, at $5,000 per vehicle and $10,000 per occurrence, filed on a BMC-34 certificate or a BMC-83 surety bond. General freight carriers have no federal cargo filing requirement — but most brokers and shippers will not tender a load without motor truck cargo coverage in place.

What is an MCS-90?

It is an endorsement attached to your liability policy, not a document filed with FMCSA. It works as a backstop for the public: it obligates your insurer to pay a judgment for public liability up to the required limit even in situations the policy itself would not cover, and you are then obligated to reimburse the insurer. It is proof of financial responsibility, not extra coverage for your business.

Do I need insurance before my MC number becomes active?

Yes. FMCSA will not grant operating authority until the required proof of insurance is on file, and a BOC-3 process agent designation is required as well. Holding a policy is not enough on its own — the filing has to be made by your insurer.

Do Texas trucking companies need different insurance than interstate carriers?

If you never leave Texas, you follow the TxDMV schedule — commonly $500,000 for vehicles over 26,000 pounds — and your insurer files a Form E. Cross a state line, or haul a load that starts or ends out of state, and the federal rules apply on top, generally at higher limits and with their own filings.

Does a USDOT number by itself require an insurance filing?

No. A USDOT Number is an identifier, not permission to haul for hire, and it does not by itself trigger a filing. For-hire operating authority is what triggers the BMC-91 filing. The safety-side rules proved by the MCS-90 endorsement are separate and depend on your vehicles, commodities and interstate operation — they reach many private carriers that never need an MC number at all.
