Texas truck regulations and laws

When it comes to heavy-duty truck repair and maintenance, understanding the regulations and laws in Texas is crucial for truck drivers and fleet managers operating in the state. Staying compliant with these regulations not only ensures safety on the road and environmental protection but also helps you avoid any expensive penalties and fines.

This comprehensive guide provides detailed insights into Texas' regulations and laws surrounding heavy-duty truck repair and maintenance. From vehicle inspections to preventive maintenance, hazardous material transportation, and environmental regulation, we cover the key aspects that every truck driver and fleet manager should know. 

I. Who Can Become a Commercial Truck Driver in Texas? 

Before we look at the requirements surrounding heavy-duty vehicles in Texas, we must first dive into who can operate them. Qualifications for commercial truck drivers in Texas are governed by specific laws to ensure the safe and responsible operation of commercial motor vehicles (CMVs). 

Age Requirement and Physical Fitness 

Drivers must be at least 21 years old and physically fit to drive. This includes passing a physical examination and a road test to demonstrate their driving skills.

English Language Proficiency

CMV drivers must have the ability to read and speak English proficiently. This is necessary for: 

  • Effective communication with the public
  • Understanding traffic signs and signals
  • Responding to inquiries from officials
  • Accurately recording information in driving reports and records

Experience and Training

Drivers must possess sufficient experience, training, or a combination of both to ensure the safe operation of a CMV. This includes knowledge of vehicle control, handling, and operating procedures specific to commercial trucks.

In addition to the qualifications, there are certain offenses that can disqualify a driver from operating a CMV for a specified period. These offenses include:

  • Driving under the Influence
    (With a blood alcohol concentration (BAC) of 0.04 percent or more, or under the influence of controlled substances or intoxicating drugs)
  • Refusing drug or alcohol testing
  • Fleeing the scene of a truck accident
  • Receiving two or more serious traffic violations within a three-year period 
  • Negligent or criminal operation
  • Driving with a suspended or revoked CDL

II. Texas Department of Transportation (TxDOT) and Federal Motor Carrier Safety Administration (FMCSA)

The Texas Department of Transportation (TxDOT) and the Federal Motor Carrier Safety Administration (FMCSA) play a pivotal role in regulating heavy-duty truck operations in Texas, including: 

Minimum Liability Insurance Coverage 

Under TxDOT and FMCSA regulations, commercial trucking companies must maintain minimum liability insurance coverage for their registered vehicles. The specific coverage depends on whether the vehicle operates interstate or intrastate, the cargo it is carrying, and its weight classification.

Intrastate Operations

For commercial motor vehicles weighing 26,000 pounds or more that transport household goods within Texas, the minimum liability insurance coverage required is $500,000. Vehicles weighing below 26,000 pounds and operating within the state must carry a minimum coverage of $300,000.

Interstate Operations

The FMCSA requires that trucks carrying household goods that are traveling interstate and weighing over 10,000 pounds maintain a minimum level of liability insurance of about $750,000.

Environmental Restoration Liability 

It is crucial that trucking companies have measures in place to mitigate any possible environmental impacts and ensure proper restoration. If an incident involving a heavy-duty truck leads to the discharge of environmentally toxic liquids or materials, environmental restoration liability is required.

Driver Coverage 

If the driver is an employee, they should ideally be covered by the trucking company's insurance policy against accidents. Independent contractors, on the other hand, must have their own primary liability policy and business liability insurance coverage.

III. Routine Maintenance

Routine maintenance is vital for the safe and efficient operation of heavy-duty trucks and helps prevent breakdowns, ensure compliance with regulations, and extend the lifespan of the vehicles.

Vehicle Inspections 

In Texas, inspections cover various aspects, including brakes, tires, lights, steering, suspension, and general vehicle condition, and are typically conducted by authorized inspection stations. It is important to keep thorough records of inspections and address any identified issues promptly.

Preventive Maintenance 

Trucking companies are responsible for implementing a preventive maintenance program to keep their heavy-duty trucks in optimal working condition. This program should include routine tasks such as oil changes, filter replacements, fluid checks, tire rotations, and other maintenance procedures as recommended by the manufacturer. 


Maintaining accurate records of all maintenance and repairs is essential for compliance and warranty claims. Trucking companies should keep records of dates, descriptions of work performed, and the names of individuals or repair shops involved. 

IV. Environmental Regulations 

As well as adhering to federal laws, Texas has specific environmental regulations to ensure that heavy-duty truck operations minimize their impact on the environment.

Texas Administrative Code, Title 30, Chapter 328 

This chapter focuses on hazardous material transportation safety regulations in Texas. It includes provisions related to the packaging, labeling, and handling of hazardous materials during transportation. 

Trucking companies must adhere to these regulations to prevent accidents, spills, and environmental contamination. Proper training of drivers and employees involved in handling hazardous materials is essential to ensuring compliance and safety.

Hazardous Waste Transportation

Transporting hazardous waste requires strict adherence to regulations outlined in the Texas Administrative Code, Title 30, Chapter 335. Trucking companies must follow guidelines for proper packaging, labeling, and manifesting of hazardous waste shipments. 

They must also comply with vehicle requirements, driver qualifications, emergency response procedures, and record-keeping to ensure safe transportation and disposal of hazardous waste. Partnering with licensed waste management facilities is crucial to ensuring proper disposal and minimizing environmental risks.


Understanding Texas' regulations and laws related to heavy-duty truck repair and maintenance is crucial for truck drivers and fleet managers. Compliance with these regulations ensures safety, protects the environment, and helps avoid legal complications. By staying informed about the specific requirements imposed by TxDOT, FMCSA, and environmental agencies, the trucking industry in Texas can operate efficiently and responsibly. 

Adhering to routine maintenance procedures, conducting thorough vehicle inspections, complying with hazardous waste transportation regulations, and utilizing expert assistance and technological solutions contribute to a safe, compliant, and sustainable trucking ecosystem. Stay compliant, prioritize safety, and maintain your heavy-duty trucks to keep Texas roads moving smoothly.
