Texas Weigh Stations, Size and Weight Enforcement, and Bypass Systems

Texas maintains one of the largest networks of commercial vehicle enforcement sites in the United States, managed primarily by the Texas Department of Public Safety (DPS) Commercial Vehicle Enforcement Division and the Texas Department of Transportation (TxDOT). The state utilizes fixed weigh stations, often located near state lines and major freight corridors like I-10, I-35, and I-45, alongside mobile enforcement teams that use portable scales. For motor carriers, navigating these stops efficiently is critical for maintaining Hours of Service (HOS) compliance and minimizing fuel burn associated with decelerating and idling. DispatchTool assists carriers in managing these operational hurdles by providing truck-safe routing that accounts for weight-restricted bridges and permanent scale locations. By integrating route planning with real-time data, DispatchTool helps dispatchers estimate arrival times more accurately despite potential enforcement delays. If you are managing a fleet or an owner-operator business in the Lone Star State, you can create a DispatchTool account to centralize your route planning and document management in one platform.

Texas DPS Enforcement and Scale Locations

The Texas DPS operates approximately 30 permanent weigh stations across the state. Major facilities are strategically positioned on I-10 near Anthony (El Paso) and Orange (Louisiana border), as well as on I-35 in Devine and Pearsall. Most permanent scales operate 24 hours a day, though hours can fluctuate based on staffing and enforcement initiatives. Drivers must look for the 'Open' or 'Closed' signage; under Texas Transportation Code Section 621.402, a peace officer who has reason to believe a vehicle is overloaded can require the driver to stop and submit to weighing at the nearest portable or stationary scale.

Weight Limits and Oversize Permits

Standard weight limits in Texas follow federal bridge formula standards: 20,000 pounds for a single axle, 34,000 pounds for a tandem axle, and a gross vehicle weight (GVW) of 80,000 pounds. TxDOT issues various permits for loads exceeding these limits, including 'General Oversize/Overweight' permits and 'Multi-State' permits. The fee for a single-trip overweight permit starts at $60 and increases based on weight and distance. Carriers exceeding 80,000 pounds without a valid permit face fines ranging from $100 to $10,000 depending on the level of excess weight and the number of prior offenses.

PrePass and Drivewyze in Texas

Texas is an active participant in both PrePass and Drivewyze bypass programs. These systems allow qualified carriers with high safety scores to bypass fixed weigh stations without stopping. Data from the PrePass Safety Alliance indicates that bypassing a scale saves an average of 5 minutes and approximately 0.4 gallons of fuel per instance. In Texas, the bypass rate is determined by the carrier's ISS (Inspection Selection System) score, which is derived from FMCSA safety data. Carriers with an ISS score below 50 are generally eligible for 'pass' signals, while those between 50 and 74 may be pulled in randomly, and those above 75 are likely to be inspected.

Virtual Weigh Stations (VWS) and WIM Technology

Texas has increasingly deployed Weigh-in-Motion (WIM) sensors and Virtual Weigh Stations (VWS). These systems use sensors embedded in the highway pavement to capture axle weights and gross weight while a truck is traveling at highway speeds. According to TxDOT, these sensors are often paired with cameras and Automated License Plate Recognition (ALPR) systems. If a VWS detects a potential violation, it alerts mobile enforcement units stationed downstream. This allows Texas DPS to target high-risk or non-compliant vehicles without disrupting the flow of legal traffic on high-volume routes like I-20 or I-30.

Agricultural and Livestock Inspection Rules

While Florida and California are known for strict ag-stops, Texas commercial vehicles carrying livestock or certain agricultural products may be subject to additional inspections under the Texas Agriculture Code. The Texas Animal Health Commission (TAHC) requires specific health papers and entry permits for livestock entering the state. Failure to stop or provide documentation at designated entry points can result in a Class C misdemeanor. Drivers should ensure that all CVI (Certificate of Veterinary Inspection) documents are current, typically within 30 days of movement, before reaching the border enforcement zones.

Penalties for Bypassing an Open Scale

Bypassing an open weigh station in Texas is a violation of state law and can lead to immediate pursuit by DPS units. Under Texas Transportation Code 621.402, failure to comply with a weight enforcement stop can lead to fines and an immediate Level I, II, or III North American Standard Inspection. These inspections contribute to a carrier’s CSA (Compliance, Safety, Accountability) score. A 'Failure to Obey' violation is often viewed as a red flag by auditors and can lead to increased frequency of future stops and inspections for the entire fleet.

Safety Inspection Levels and Requirements

Texas DPS officers conduct thousands of roadside inspections annually following Commercial Vehicle Safety Alliance (CVSA) standards. A Level I inspection is the most comprehensive, covering both driver credentials (CDL, Medical Card, HOS logs) and vehicle mechanical components like brakes, lighting, and coupling devices. According to the FMCSA’s MCMIS data, the most common vehicle violations in Texas involve lighting and brake adjustments. Keeping an organized cab and maintaining an updated ELD (Electronic Logging Device) is essential for passing these 30-to-60-minute inspections without receiving points against your safety record.

Frequently asked

What is the maximum weight for a truck in Texas without a permit?

The maximum legal gross vehicle weight (GVW) is 80,000 pounds. Single axles are limited to 20,000 pounds and tandem axles to 34,000 pounds, provided they follow the federal bridge formula.

Do I have to stop at a weigh station if I have a bypass transponder?

If your PrePass or Drivewyze device gives a green light or 'bypass' signal, you may proceed. However, if the device gives a red light or fails to signal, you must pull into the open scale as required by Texas law.

Are empty trucks required to stop at Texas weigh stations?

Yes, all commercial motor vehicles with a GVWR or GCWR over 10,000 pounds must stop at open weigh stations in Texas, regardless of whether they are carrying a load or traveling empty.

What are the fines for being overweight in Texas?

Fines vary based on the amount of excess weight. For example, being 2,500 pounds overweight can result in a fine of $100 to $500, while exceeding 10,000 pounds over the limit can result in fines up to $10,000 for repeat offenders.

Where are the most active weigh stations in Texas located?

The highest volume weigh stations are located on I-10 near the Louisiana border (Orange), I-10 near the New Mexico border (Anthony), and I-35 in the Eagle Ford Shale region (Devine).
