DOT Inspections and Enforcement in Texas

Commercial vehicle enforcement in Texas is primarily managed by the Texas Department of Public Safety (DPS) under the authority of Texas Transportation Code Chapter 644. The state operates over 25 permanent weigh stations and numerous mobile enforcement units that conduct North American Standard Inspections. Texas leads the nation in total annual inspections due to the high volume of interstate commerce and international trade along the I-35 and I-10 corridors. Motor carriers must adhere to both the Federal Motor Carrier Safety Regulations (FMCSR) and specific Texas Administrative Code Title 37 rules to avoid significant penalties. To maintain compliance during these roadside stops, carriers use DispatchTool to store and transmit digital logs, inspection reports, and maintenance records instantly. Dispatchers use the platform to monitor driver hours of service in real-time, reducing the risk of Level I violations related to logbook inaccuracies or expired medical certificates. By centralizing documentation, fleets can provide immediate proof of compliance to Texas DPS troopers, potentially shortening the duration of roadside stops.

Texas DPS Enforcement Authority and CVSA Levels

The Texas Department of Public Safety (DPS) Commercial Vehicle Enforcement (CVE) division performs six levels of CVSA inspections. The Level I North American Standard Inspection is the most comprehensive, involving a 37-step procedure that includes an examination of the driver's credentials and a mechanical inspection under the vehicle. Level II is a walk-around driver/vehicle inspection, while Level III focuses solely on driver credentials, including CDL validity, Medical Examiner’s Certificate, and Record of Duty Status (RODS). In 2023, Texas performed over 400,000 inspections, frequently identifying lighting violations and brake adjustment issues as top infractions. Level IV through VI are specialized inspections for trends, explosives, or radioactive materials.

Weight and Size Limits on Texas Highways

Texas enforcement strictly monitors weight limits defined in Texas Transportation Code Section 621.101. The gross vehicle weight (GVW) limit for most commercial vehicles is 80,000 pounds, with single axle limits at 20,000 pounds and tandem axle limits at 34,000 pounds. Vehicles exceeding these limits without a valid TxDMV oversize/overweight permit face tiered fines starting at $100 and scaling up to $10,000 for egregious violations. The state utilizes Weigh-in-Motion (WIM) technology at major points like the Riviera or Devine stations to pre-screen trucks, allowing compliant carriers to bypass scales while flagging overweight loads for secondary inspection.

Intrastate vs. Interstate Regulations

Texas distinguishes between intrastate and interstate carriers under 37 Texas Administrative Code § 4.11. Intrastate carriers operating vehicles with a GVWR of 26,001 pounds or more, or those transporting hazardous materials, must obtain a TxDMV number. While interstate carriers follow the 70-hour/8-day or 60-hour/7-day HOS limits, Texas intrastate drivers benefit from a 12-hour driving limit and a 15-hour on-duty limit after 8 consecutive hours off duty. Additionally, intrastate carriers are subject to the 70-hour/7-day rule, providing more flexibility than federal standards for drivers who do not cross state lines.

Common Roadside Violations and Fines

The Texas DPS focuses heavily on 'moving' violations within construction zones and rural two-lane highways. Common mechanical violations include inoperative lamps, which can result in a fine of approximately $230 depending on the county jurisdiction. Brake system violations account for roughly 25% of all vehicle out-of-service (OOS) orders in Texas. According to the FMCSA Analysis & Information Online database, failure to use a seatbelt and speeding 6-10 mph over the limit are the most frequent driver-related citations in the state. Each violation adds points to the carrier's CSA (Compliance, Safety, Accountability) score, impacting insurance premiums and future inspection frequency.

Out-of-Service (OOS) Criteria and Recovery

If a vehicle or driver is placed Out-of-Service during a Texas DOT inspection, they cannot move the vehicle until the violation is corrected. For mechanical OOS orders, such as a 20% brake failure or steer tire tread depth below 4/32 of an inch, the carrier must often dispatch a mobile repair unit to the scale or roadside location. Driver OOS orders, often triggered by HOS violations or a lack of English proficiency, typically require a 10-hour or 34-hour restart period. Operating a vehicle while under an OOS order is a serious violation that can lead to a $2,500 civil penalty for the driver and up to $10,000 for the employer under FMCSR Part 383.53.

Annual Inspection Requirements

Under Texas Transportation Code § 548.203, commercial motor vehicles must undergo a state-mandated annual safety inspection. This is often integrated with the federal annual inspection required by 49 CFR § 396.17. The fee for a commercial vehicle inspection in Texas varies by county but generally ranges between $40 and $70. The inspection covers steering, tires, wheels, exhaust, lighting, and braking systems. Documentation of this inspection must be kept in the vehicle at all times, as failure to produce a valid inspection report during a Level II roadside check will result in an immediate citation.

Frequently asked

What is the fine for an overweight truck in Texas?

Fines for overweight violations in Texas are calculated based on the excess weight. For example, 1 to 2,500 pounds over limit usually results in a fine between $100 and $500, while exceeding the limit by more than 10,000 pounds can result in a fine up to $10,000 for repeat offenders.

Do I need an ELD for intrastate trucking in Texas?

Yes, Texas adopted the federal ELD mandate for intrastate carriers. Drivers must use a registered Electronic Logging Device unless they qualify for the short-haul exemption (operating within a 150 air-mile radius) or are driving a vehicle manufactured before the year 2000.

Where are the major weigh stations in Texas located?

Texas has significant inspection facilities on I-10 near Anthony, I-35 near Laredo (World Trade Bridge), and I-45 near Huntsville. There are also high-activity mobile enforcement zones in the Permian Basin due to heavy oilfield traffic.

How long do I have to fix a fix-it ticket from a DOT inspection?

For non-OOS violations, carriers generally have 15 days to repair the defect and return the signed inspection report to the Texas DPS to certify that the repairs were completed, as per CVSA standards.
