Do I need a USDOT number to operate intrastate in Texas?
A Texas-domiciled motor carrier operating only in intrastate commerce needs both a USDOT number (designated intrastate) and a TxDMV motor carrier registration — the TxDMV Number. The USDOT number is obtained first; the TxDMV registration follows through TxMCCS, the Texas Motor Carrier Credentialing System that replaced the older MCCS and eLINC systems.
Tex. Transp. Code §643.051 requires the registration to operate a commercial motor vehicle as defined by §548.001, and TxDMV lists the triggers as:
- A vehicle or combination with gross weight, registered weight, or GVWR of more than 26,000 lbs
- Transport of hazardous materials in placardable quantities
- A farm vehicle only at 48,000 lbs or more (lighter farm vehicles are excluded from the §548.001 definition)
- A vehicle designed or used to transport more than 15 passengers including the driver
- A commercial school bus
- Transport of household goods for compensation, regardless of weight
The TxDMV Number runs alongside the USDOT number — it does not replace it. Carriers at or below 26,000 lbs who do not haul placardable hazmat, more than 15 passengers, or household goods generally fall outside the TxDMV registration requirement, though USDOT thresholds still apply on their own terms for interstate operations. Registration is available for seven days, 90 days, one year, or two years; 7-day and 90-day certificates cannot be renewed, and household-goods and hazmat carriers are not eligible for them. The TxDMV Motor Carrier Handbook is the controlling document for thresholds, fee brackets, and renewal terms.
Which agencies regulate motor carriers in Texas?
Three Texas state agencies divide motor carrier regulation, and the lines between them matter when something goes wrong.
- Texas Department of Motor Vehicles (TxDMV), Motor Carrier Division issues the TxDMV Number, handles operating authority, IRP registration, and insurance filings (Form E). TxDMV explicitly notes that it does not handle driver licensing or safety audits.
- Texas Department of Public Safety (Texas DPS), Commercial Vehicle Enforcement bureau handles roadside inspections, weigh-station enforcement, safety audits including new-entrant audits, and the state’s drug-and-alcohol testing reporting program. DPS is the agency that will appear at an audit.
- Texas Comptroller of Public Accounts administers IFTA and motor fuel taxes and receives the 10 percent Texas Emissions Reduction Plan surcharge that county tax assessor-collectors collect on combination registrations.
Texas does not have a public utility commission for trucking. The Railroad Commission of Texas regulates oil and gas, not motor freight.
What’s different about compliance in Texas?
Texas layers a handful of state-specific obligations on top of the federal motor carrier rules every domiciled carrier must already follow.
- Drug-and-alcohol testing results reporting to DPS. Tex. Transp. Code §644.252 requires every employer that tests CDL drivers under the federal rules to report to Texas DPS each valid positive alcohol or drug result (and whether the specimen was dilute), each refusal to provide a specimen, and each adulterated or substituted specimen. DPS takes the reports on forms MCS-19 (alcohol) and MCS-20 (drug) through its Motor Carrier Bureau under 37 Tex. Admin. Code §4.21. The TxDMV registration application separately requires a certification of Part 382 compliance (§643.052(6)). Running a federal-compliant program does not, by itself, satisfy the Texas reporting obligation.
- Texas Emissions Reduction Plan (TERP) surcharge. Under Tex. Transp. Code §502.358, a truck-tractor or commercial motor vehicle registered in combination with a semitrailer (§502.255) pays a 10 percent TERP surcharge on its registration fee, collected by the county tax assessor-collector and remitted to the Texas Comptroller. It is a small line item per vehicle but a recurring one, and it is the most commonly missed Texas-specific cost in a new-entrant operating budget.
- Non-CMV vehicle safety inspection abolished. As of January 1, 2025, House Bill 3297 (88th Legislature) ended the annual safety inspection sticker requirement for non-commercial vehicles. The federal annual inspection requirement for commercial vehicles at or above 10,001 lbs GVWR under 49 CFR §396.17 remains in force unchanged, and Texas still inspects commercial motor vehicles annually under Tex. Transp. Code §548.201 — a program FMCSA lists as equivalent to its periodic inspection rule, so the Texas CMV inspection satisfies §396.17 under §396.23(a)(1). Carriers operating mixed light-duty and heavy-duty fleets sometimes assume the HB 3297 change covers both. It does not.
- Electronic-only medical examiner’s certificate filing. Since June 23, 2025, certified medical examiners must transmit CDL and CLP examination results electronically through the FMCSA National Registry, which forwards them to Texas DPS; DPS stopped accepting paper medical certificates on April 10, 2026, per its CDL medical certification page.
- No state Employer Pull Notice equivalent. Texas does not run a state-level program that pushes MVR changes to carriers between annual reviews. The annual review of driving record under 49 CFR §391.25 is the federal floor and the practical ceiling.
What does intrastate operation cost?
Annual cost categories for a Texas-domiciled small carrier:
- Unified Carrier Registration (UCR). Per the UCR Plan’s board-approved 2026 fee schedule: $46.00 per entity for 0–2 vehicles, $138.00 for 3–5, and $276.00 for 6–20. Texas is a UCR participating state, so Texas-domiciled carriers file directly through Texas. Source: UCR Plan fee brackets. For registration year 2027 and after, FMCSA raised these to $55.00 (0–2), $167.00 (3–5), and $333.00 (6–20) — 91 FR 56063, effective October 1, 2026 (49 CFR §367.50).
- TxDMV Motor Carrier Registration. Available for 7 days, 90 days, one year, or two years. Per TxDMV’s fee table: an application fee of $5 (7-day), $25 (90-day), or $100 (annual or biennial); $10 per vehicle ($20 per vehicle for two years); and a $100 insurance filing fee (Form E) — the statutory amounts are in Tex. Transp. Code §§643.053 and 643.061. Questions go to TxDMV’s Motor Carrier Division at 800-299-1700.
- TERP surcharge. 10 percent of the registration fee for a truck-tractor or CMV registered in combination (§502.358), paid with the registration.
- IRP (apportioned registration). Texas is a base jurisdiction. Fees are the proportion of fleet distance in each jurisdiction multiplied by that jurisdiction’s base registration schedule.
- IFTA. Administered by the Texas Comptroller. Quarterly returns are due on the last day of the month after each calendar quarter: April 30, July 31, October 31, and January 31.
- Weight-mile or ton-mile tax. None. Texas does not impose a per-mile tax on commercial trucks above and beyond fuel tax.
- Federal Heavy Vehicle Use Tax (Form 2290). Vehicles at or above 55,000 lbs gross weight owe HVUT to the IRS; proof of payment is a prerequisite for IRP registration of the vehicle.
How are state-level audits and inspections handled?
Texas runs both a state audit program and the country’s largest MCSAP enforcement operation. The two operate in parallel.
State audits. 37 Texas Administrative Code §4.15 authorizes Texas DPS to conduct new-entrant safety audits on Texas-domiciled interstate motor carriers under 49 CFR Part 385, Subpart D, and to run compliance reviews (§4.15(b)(2)) based on:
- Unsatisfactory safety assessment factor evaluations
- Substantiated written complaints — which for this purpose include a fatality crash or a 24-hour out-of-service notification for a §392.4 or §392.5 (drugs or alcohol) violation
- Follow-up after an enforcement action, administrative penalty, or unsatisfactory rating from the previous review
- Requests from the legislature or a state or federal agency
- A request for, or to change, a safety rating
- A hazardous materials incident
DPS can also issue an imminent-hazard order to cease operations outside the normal audit cycle when conditions warrant it. The new-entrant audit covers driver qualification (Part 391), hours of service (Part 395), vehicle maintenance and inspection (Part 396), drug-and-alcohol testing (Part 382 — including the Texas §644.252 reporting overlay), and operational compliance (financial responsibility, hazmat where applicable, accident register).
Roadside inspections. Texas DPS staffs 269 fully salaried CVE positions (88 commissioned) plus 144 civilian border inspectors, per the FY2024–2026 Texas Commercial Vehicle Safety Plan. Inspections concentrate along I-10, I-20, I-35, I-30, and I-45, and at the Laredo Port of Entry. For a small carrier, this means roadside exposure in Texas is materially higher than in most other states. The practical defenses are familiar: current annual inspection records (§396.17), a clean DVIR habit (§396.11) where applicable, a complete driver qualification file (§391.51), and accurate hours-of-service records (§395.8).
Texas does not run a state terminal-inspection program comparable to California’s BIT. Terminals are not inspected on a fixed schedule, only on event-driven cause.
