Texas trucking company regulations exist to protect everyone who shares the road with large commercial vehicles. These rules govern everything from driver qualifications to vehicle weight limits and maintenance standards. When trucking companies fail to follow these requirements, the consequences can be devastating. Understanding the regulations that apply to the trucking industry is essential for victims seeking to hold negligent parties accountable after a serious crash.
Overview of Texas Trucking Regulations
Texas trucking regulations form an extensive system of rules that commercial carriers and their drivers must follow at all times. Both federal and state agencies play a role in setting and enforcing these standards. The regulations cover driver hours, vehicle weight, equipment condition, insurance coverage, drug testing, and more. Texas roads carry more commercial freight than almost any other state in the nation, making strict regulatory oversight critical. When carriers cut corners or ignore established rules, innocent drivers and passengers bear the consequences through serious and sometimes fatal collisions. Understanding these standards helps accident victims and their attorneys identify liability and pursue full compensation.

Federal vs. State Regulations
Texas trucking is governed by both federal and state law. The Federal Motor Carrier Safety Administration (FMCSA) sets baseline standards that apply to all interstate commercial carriers operating across state lines. These federal rules address hours of service, driver qualifications, drug testing, and vehicle maintenance. Texas also enforces its own state-level regulations through the Texas Department of Motor Vehicles (TxDMV) and the Texas Department of Transportation (TxDOT), which address intrastate carriers and supplement federal rules. When a trucking company operates only within Texas, state rules may be the primary source of regulation. In many cases, both bodies of law apply simultaneously, and a violation of either can be used to establish negligence in a personal injury claim.
TXDMV and TxDOT: Key Regulatory Agencies
The Texas Department of Motor Vehicles (TxDMV) and the Texas Department of Transportation (TxDOT) are the two primary state agencies responsible for overseeing the commercial trucking industry. TxDMV handles the registration and permitting of commercial vehicles, including oversize and overweight load permits. TxDOT is responsible for highway safety, infrastructure, and enforcement of state transportation rules. Together, these agencies work in coordination with federal authorities to ensure that commercial carriers operating in Texas meet all applicable safety standards. Both agencies have the authority to audit carrier records, conduct inspections, and impose penalties for violations. Their findings can become critical evidence in truck accident litigation.

Licensing and Registration Requirements
Texas trucking companies and their drivers must satisfy several licensing and registration requirements before operating on public roads. Each requirement is designed to verify that carriers are legally authorized, financially responsible, and operating roadworthy vehicles.
- Commercial Driver’s License (CDL). Every driver operating a commercial motor vehicle in Texas must hold a valid CDL issued by the Texas Department of Public Safety. The CDL class must match the vehicle type being driven, and drivers must pass written and skills tests.
- USDOT Number. Commercial carriers that operate in interstate commerce or meet certain size thresholds must obtain a USDOT number from the Federal Motor Carrier Safety Administration. This number is used to track a carrier’s safety record and compliance history.
- Texas Motor Carrier Registration. Companies hauling goods for compensation in Texas must register with TxDMV as a motor carrier. This registration confirms the carrier has met insurance requirements and is authorized to operate commercially within the state.

| Maximum Combination Length | 65 feet (up to 85 feet with permit) |
Hours of Service Rules in Texas
Hours of service (HOS) rules limit how long commercial drivers may operate without rest. Texas follows the federal FMCSA hours of service regulations for interstate carriers. Property-carrying drivers may drive a maximum of 11 hours after 10 consecutive hours off duty. Drivers may not drive beyond the 14th consecutive hour after coming on duty. A 30-minute rest break is required after 8 cumulative hours of driving. The 60/70-hour rule limits total on-duty time over 7 or 8 consecutive days. Intrastate Texas drivers operating only within the state follow slightly different HOS rules under Texas law but are still subject to meaningful restrictions designed to prevent fatigued driving.
ELD (Electronic Logging Device) Requirements
Electronic Logging Device (ELD) requirements are a critical component of hours of service enforcement for commercial truck drivers. Federal law requires most commercial motor vehicle drivers who are required to keep records of duty status to use an ELD to automatically track drive time and ensure compliance. ELDs sync with a vehicle’s engine to record data on driving time, engine hours, vehicle movement, and location. Carriers must retain ELD records for at least six months. Exemptions exist for drivers who operate under the short-haul exemption or who use time cards. ELD data is frequently sought as evidence in truck accident cases because it can confirm or contradict a driver’s claimed hours and reveal whether fatigue was a contributing factor in a crash.
Drug and Alcohol Testing Requirements
Federal and Texas regulations impose strict drug and alcohol testing requirements on commercial drivers. These rules are designed to keep impaired drivers off public roads and reduce the risk of deadly collisions.
- Pre-Employment Testing. Before a commercial driver begins work, the carrier must conduct a drug test. Drivers must test negative before operating any commercial vehicle on behalf of the employer.
- Random Testing. Carriers are required to conduct random, unannounced drug and alcohol testing of their drivers throughout the year. The FMCSA sets minimum annual testing rates for both drugs and alcohol to ensure ongoing compliance.
- Post-Accident Testing. Following any qualifying accident, the carrier must test the driver for drugs and alcohol as soon as possible. A qualifying accident typically involves a fatality, injury requiring medical treatment, or vehicle tow.
- Return-to-Duty Testing. Drivers who have tested positive or violated drug and alcohol policies must complete a return-to-duty process, which includes a substance abuse evaluation and a negative return-to-duty drug test before resuming safety-sensitive functions.
Vehicle Maintenance and Inspection Standards
Vehicle maintenance and inspection standards require carriers to keep their commercial vehicles in safe operating condition at all times. Federal regulations mandate that carriers establish a systematic inspection, repair, and maintenance program for every vehicle in their fleet. Drivers must complete a pre-trip inspection before each trip and submit a written driver vehicle inspection report (DVIR) at the end of each day. Any defects that could affect safe operation must be repaired before the vehicle returns to service. Carriers must retain maintenance records for a minimum period as required by federal rules. Failure to properly maintain brakes, tires, lighting, steering, or other critical systems is a common cause of serious truck accidents and a frequent basis for liability claims.
Driver Qualification Requirements
Carriers are responsible for ensuring that every driver they employ meets all federal and state qualification standards. These requirements are designed to confirm that drivers have the training, experience, and physical ability to safely operate commercial vehicles.
- Valid Commercial Driver’s License. Every driver must hold a current CDL appropriate for the vehicle class being driven, and the carrier must verify the license is valid before allowing the driver to operate.
- Driver Qualification File. Carriers must maintain a driver qualification file for each driver that includes employment history, motor vehicle record checks, road test certifications, and annual reviews of driving records.
- Medical Certificate. Commercial drivers must obtain a medical examiner’s certificate confirming they meet the physical standards required by the FMCSA, and this certificate must be renewed periodically to verify ongoing fitness for duty.
- Safety Performance History. Before hiring a driver, carriers must investigate the driver’s safety performance history with previous employers for the past three years, including any accidents or drug and alcohol violations.
Insurance and Financial Responsibility
Insurance and financial responsibility requirements ensure that trucking companies can compensate victims when their negligence causes harm. Under federal law, interstate commercial carriers must carry a minimum level of liability insurance based on the type of cargo hauled. For general freight carriers, the federal minimum is $750,000, while hazardous materials carriers may be required to carry up to $5 million in coverage. Texas also imposes its own financial responsibility requirements on intrastate carriers. Proof of insurance must be filed with the FMCSA or TxDMV and must be kept current at all times. A lapse in coverage can result in suspension of operating authority. For accident victims, identifying all available insurance policies, including those of the carrier, driver, and cargo owner, is a key step in pursuing full compensation for injuries and losses.
How Regulation Violations Lead to Accidents
Regulation violations are a leading cause of serious truck accidents in Texas. When carriers and drivers ignore established safety rules, the probability of a catastrophic crash increases significantly.
- Hours of Service Violations. Drivers who exceed allowable driving hours become dangerously fatigued, slowing reaction time and impairing judgment in ways that closely mirror the effects of alcohol impairment.
- Overweight Loads. Trucks carrying loads that exceed legal weight limits require significantly greater stopping distances, are more prone to tire blowouts, and impose dangerous handling characteristics on the driver.
- Inadequate Vehicle Maintenance. Failing to perform required inspections and repairs allows brake failures, tire defects, and lighting malfunctions to go unaddressed, creating direct causes of preventable collisions.
- Unqualified Drivers. Placing unlicensed, impaired, or inadequately trained drivers behind the wheel of an 80,000-pound commercial vehicle dramatically increases the likelihood of an accident injuring or killing other road users.
- Drug and Alcohol Violations. Carriers that fail to conduct required testing or allow drivers with positive tests to continue operating put every other person on the road at serious risk of catastrophic harm.
Hours of Service Violations
Hours of service violations are among the most dangerous forms of regulatory noncompliance in the trucking industry. When drivers exceed the federally mandated limits on consecutive driving hours, fatigue sets in rapidly. Studies have shown that drowsy driving can impair a person’s abilities as severely as drunk driving, with dramatically reduced reaction times and impaired decision-making. A fatigued truck driver operating an 80,000-pound vehicle at highway speeds has limited ability to respond to sudden hazards. ELD tampering, falsified logbooks, and carrier pressure to meet unrealistic delivery deadlines are all common contributors to hours of service violations. These violations are often discoverable through electronic records and can be powerful evidence in establishing trucking company liability.
Overweight Trucks
Overweight trucks pose serious dangers to other drivers and to the integrity of Texas roads and bridges. A commercial vehicle that exceeds legal weight limits requires substantially more distance to come to a complete stop, which can make rear-end collisions inevitable when unexpected traffic slowdowns occur. Excessive weight also puts extreme stress on tires, increasing the risk of sudden blowouts at highway speeds. Overloaded trucks are harder to control in curves and emergency maneuvers. Carriers may overload vehicles to reduce the number of trips required to deliver cargo, prioritizing profit over public safety. When an overweight truck causes an accident, evidence from weigh station records, cargo documentation, and post-accident vehicle inspections can establish that the carrier violated weight regulations.
Your Rights When a Company Violates Regulations
Your rights as an accident victim do not disappear simply because a trucking company has deep pockets or powerful legal representation. When a carrier or driver violates federal or state trucking regulations, those violations can serve as direct evidence of negligence in a personal injury claim. Texas law allows injured victims to seek compensation for medical expenses, lost wages, pain and suffering, and other damages caused by a negligent carrier. In some cases involving egregious misconduct, such as knowingly allowing an unqualified or impaired driver to operate a vehicle, punitive damages may also be available. Victims have the right to demand preservation of evidence, including ELD data, maintenance records, and driver qualification files, before that evidence is destroyed or lost.
What Is the Maximum Weight for a Semi-Truck in Texas?
The maximum weight for a semi-truck in Texas is generally 80,000 pounds gross vehicle weight under standard regulations. This includes the combined weight of the truck, trailer, and cargo. Individual axle limits also apply, with a maximum of 20,000 pounds per single axle and 34,000 pounds per tandem axle group. Carriers that need to haul heavier loads must obtain an oversize/overweight permit from TxDMV. Operating above legal weight limits without a permit is a violation that can lead to fines and, more importantly, can constitute negligence if an overloaded truck causes a serious accident resulting in injury.
How Many Hours Can a Truck Driver Legally Drive?
Under federal FMCSA rules, a property-carrying commercial truck driver may drive a maximum of 11 hours following 10 consecutive hours off duty. Drivers may not drive after the 14th consecutive hour after coming on duty. A mandatory 30-minute rest break is required after 8 cumulative hours of driving without at least a 30-minute interruption. The 60/70-hour rule caps total on-duty time to 60 hours in 7 days or 70 hours in 8 days. Texas intrastate drivers are subject to slightly different limits. These rules exist specifically to prevent fatigue-related crashes, and violations of HOS limits are a common finding in serious truck accident investigations.
Do Texas Trucking Companies Have to Carry Insurance?
Yes, Texas trucking companies are required by both federal and state law to carry liability insurance. Interstate carriers regulated by the FMCSA must maintain minimum liability coverage of $750,000 for general freight and up to $5 million for hazardous materials. Texas state law imposes similar financial responsibility requirements on intrastate carriers. Proof of insurance must be filed and kept current with the appropriate regulatory agency. In addition to the carrier’s own policy, there may be additional coverage available through broker policies, shipper policies, or cargo insurance. A truck accident attorney can help identify all available insurance sources to ensure victims have the opportunity to pursue full compensation for their injuries.
Can I Sue for Violating Safety Regulations?
Yes, a victim injured in a truck accident can pursue a civil lawsuit against a trucking company or driver whose violation of safety regulations contributed to the crash. In Texas, a regulatory violation, such as exceeding hours of service limits, operating an overweight vehicle, or failing to maintain required equipment, can be used to establish negligence per se, meaning the violation itself is treated as evidence of negligence. This can significantly strengthen a victim’s claim. Victims may recover damages for medical bills, lost income, physical pain, and emotional suffering. The strength of the case often depends on how quickly evidence is gathered and preserved after the accident.
