Overloaded Trucks
Overloaded Truck Accident Lawyer in San Antonio
Federal and state weight limits exist for a critical reason — an overloaded commercial truck is significantly harder to stop, more difficult to steer, and far more likely to experience catastrophic mechanical failures such as brake failure, tire blowouts, and structural collapse. When trucking companies and shippers ignore these weight restrictions to maximize revenue per trip, they create deadly hazards for every motorist sharing the road.
At the Law Offices of Ronald A. Ramos, P.C., we represent San Antonio accident victims injured by overweight and improperly loaded commercial trucks. These cases often involve multiple liable parties — including the trucking company, the shipper, and the loading facility — and require a thorough understanding of both federal weight regulations and the physics of how overloading affects vehicle performance.
Federal and Texas Weight Limits for Commercial Trucks
The federal Bridge Formula and FMCSA regulations establish maximum weight limits for commercial vehicles operating on interstate highways. The gross vehicle weight rating (GVWR) cannot exceed 80,000 pounds for a standard five-axle tractor-trailer combination. Individual axle limits include 20,000 pounds per single axle and 34,000 pounds per tandem axle. The steer axle is limited to 12,000 pounds.
Texas enforces these federal limits on interstate highways and imposes its own weight regulations on state roads under Texas Transportation Code Chapter 621. The Texas Department of Public Safety operates weigh stations and portable scale operations across the state. Carriers found operating overweight vehicles face fines, out-of-service orders, and potential criminal penalties for repeat violations.
Despite these regulations, overloading remains prevalent in the trucking industry because carriers can increase per-trip revenue by hauling more cargo. The economic incentive to overload is particularly strong for bulk commodity haulers transporting materials like gravel, sand, concrete, steel, and agricultural products — all common on San Antonio highways.
How Overloading Causes Accidents
Increased stopping distance is the most dangerous consequence of overloading. A fully loaded truck traveling at highway speed already requires 40 percent more distance to stop than a passenger car. Adding weight beyond legal limits extends stopping distance even further, making it impossible for the driver to react safely to sudden traffic changes, red lights, or highway construction zones.
Brake failure occurs when the additional weight exceeds the braking system’s capacity. Commercial truck brakes are engineered and rated for the vehicle’s legal maximum weight. Operating above that weight puts excessive thermal stress on brake components, leading to brake fade — a condition where overheated brakes lose effectiveness — and potential total brake failure. This is especially dangerous on downhill grades, highway exit ramps, and in stop-and-go traffic conditions common on I-35 and I-10 through San Antonio.
Tire blowouts caused by overloading are another frequent cause of accidents. Each tire is rated for a specific load capacity, and exceeding that rating accelerates wear, increases internal heat, and dramatically raises the risk of sudden failure. A blowout on a loaded truck traveling at highway speed can send the vehicle across multiple lanes of traffic. Structural failures — including frame cracks, suspension collapse, and coupling device failures — can cause the truck to lose control entirely or separate from its trailer.
Rollover Risk and Overloaded Trucks
Overloading raises the truck’s center of gravity, making the vehicle inherently less stable. An overloaded truck is significantly more likely to roll over during turns, lane changes, or evasive maneuvers. When cargo is also improperly distributed — with too much weight on one side or stacked too high — the rollover risk multiplies. Rollover accidents involving overloaded trucks are among the most devastating highway incidents, often blocking multiple lanes and causing multi-vehicle pileups.
Liability for Overloaded Truck Accidents
Multiple parties may share responsibility when an overloaded truck causes an accident. The motor carrier is responsible for ensuring its vehicles operate within legal weight limits and must refuse loads that would cause overweight conditions. The shipper or consignor who loaded the cargo may be liable if they misrepresented the cargo weight, overloaded the vehicle at the loading facility, or pressured the carrier to accept an overweight load.
The loading facility may bear liability if their personnel improperly loaded or distributed the cargo. In some cases, freight brokers who arranged the shipment can also be held liable if they knew or should have known the load exceeded legal limits. Under Texas proportionate responsibility rules in TCPRC Chapter 33, each party’s share of fault is determined based on their contribution to the dangerous condition.
Key evidence in overloaded truck cases includes weight station records and bypass data, bill of lading documents showing cargo weight, scale tickets from the loading facility, driver’s pre-trip inspection reports, and post-accident vehicle inspections that reveal overweight conditions. Our legal team secures this evidence immediately through preservation demands and, when necessary, emergency court orders.
Compensation for Overloaded Truck Accident Injuries
Victims of overloaded truck accidents in Texas may recover compensation for medical expenses, lost wages, pain and suffering, property damage, and other losses. Because overloading is typically a deliberate business decision to increase profits at the expense of safety, these cases may also support claims for punitive damages under TCPRC Section 41.003 — particularly when the carrier has a history of overweight violations or internal communications show knowledge of the dangerous practice.
