Texas DOT Regulations for Truck Drivers: Rules for Commercial Vehicles

Texas DOT regulations for truck drivers outline specific rules to ensure road safety and compliance for all commercial vehicles. These regulations cover critical areas like driving limits, weight restrictions, and maintenance standards to prevent accidents. Following these rules is essential for drivers and companies to avoid fines, reduce risks, and ensure safe operations on Texas roads.

What are the Texas DOT regulations for truck drivers?

The DOT regulations Texas has in place exist to protect public safety, ensure smooth operations, and prevent accidents involving large trucks. Texas commercial vehicle regulations align with federal standards established by the Federal Motor Carrier Safety Administration (FMCSA) while also addressing specific concerns for Texas roads and highways.

But, why are these laws and regulations important? 

These commercial vehicle regulations are designed to minimize the risk of accidents, protect infrastructure, and maintain the safety of drivers and the public. Trucks operate under unique conditions and pose significant dangers if poorly maintained or driven unsafely. By enforcing these regulations, Texas ensures that trucking companies and drivers operate responsibly, protecting road users and maintaining smooth commercial operations across the state.

These regulations also help prevent fines and penalties, avoiding disruptions that could affect the supply chain and financial stability of trucking businesses. Staying compliant ensures legal operation and builds trust between trucking companies, their clients, and the public.

Below is an overview of key areas governed by Texas DOT regulations for truck drivers.

Texas DOT rules and regulations

Texas DOT rules and regulations provide a framework for truck drivers and companies to ensure safety, compliance, truck accident liability, and smooth operations across the state. These rules govern driver behavior, vehicle maintenance, cargo management, and insurance requirements.

Staying compliant with Texas trucking laws not only helps drivers avoid penalties but also enhances public safety. Below is a detailed breakdown of the key rules and new truck regulations that impact commercial drivers in Texas.

Size and Weight Limits

Size and weight regulations in Texas are critical to protecting road infrastructure and ensuring vehicle stability on highways:

  • Maximum Gross Vehicle Weight (GVW): Texas restricts the gross vehicle weight for commercial trucks to a maximum of 80,000 pounds. This includes the truck’s own weight, the weight of the cargo, fuel, and any additional equipment.
  • Axle-Specific Limits: Single axles are restricted to 20,000 pounds, while tandem axles (two axles close together) are limited to 34,000 pounds.
  • Oversized and Overweight Permits: Trucks exceeding these weight limits must secure permits. Oversized trucks may also have designated routes, specific hours, or even pilot vehicles to ensure safe passage through Texas highways.
  • Bridge and Highway Safety: Heavier trucks can deteriorate infrastructure faster, so compliance with these limits helps reduce the frequency and cost of repairs on Texas roads.

Commercial Driver’s License (CDL) Requirements

To operate a commercial truck in Texas, drivers must meet several CDL requirements to ensure they’re fit for the road:

  • Obtaining a CDL: Drivers must complete specific training, pass written knowledge and skills tests, and hold a CDL appropriate to their vehicle class.
  • Endorsements for Specialized Cargo: Drivers need endorsements to carry specialized loads, like hazardous materials or oversized cargo. These endorsements require additional tests and background checks.
  • Medical Examinations: Drivers must pass a medical exam every two years to ensure they’re physically and mentally able to handle the rigors of commercial driving.
  • Maintaining a Clean Record: Serious traffic violations can result in CDL suspensions or permanent disqualifications, so drivers must adhere to high safety standards.

Hours of Service (HOS) Compliance

HOS regulations set limits on how long truck drivers can operate before needing rest, preventing fatigue-related accidents:

  • Intrastate Driving Hours: Texas allows drivers to operate up to 12 hours within a 15-hour on-duty window for intrastate (within Texas) trips. This ensures that there is no truck driver fatigue or accidents caused by this. 
  • Mandatory Rest Breaks: After 8 hours of driving, drivers must take a 30-minute break. Additionally, drivers must have 8 consecutive off-duty hours before starting their next shift.
  • Weekly Limit: Drivers cannot work more than 70 hours in an 8-day period. They must take a 34-hour off-duty period (the “restart” rule) to reset this weekly limit.
  • Short-Haul Exception: For drivers operating within a 150-air-mile radius, Texas allows a 14-hour on-duty day, providing flexibility for shorter trips without HOS penalties.

Vehicle Maintenance and Repair Requirements

Proper maintenance is essential for ensuring that commercial trucks operate safely and efficiently on Texas roads:

  • Daily Inspections: Truck drivers must perform pre-trip and post-trip inspections daily, checking critical components like brakes, tires, lights, and coupling devices.
  • Annual Inspections: Trucking companies must conduct annual inspections that assess all safety components, including the braking system, steering mechanism, suspension, and lighting. This inspection ensures compliance with Texas safety standards.
  • Record Keeping: Trucking companies are required to maintain thorough records of maintenance, repairs, and inspection reports for each vehicle. These records must be available for DOT review in case of an audit.
  • Repair Timeliness: If defects are identified, they must be repaired promptly before the truck returns to service to prevent potential hazards.

Insurance Coverage

Adequate insurance coverage is mandatory for all commercial trucks operating in Texas, providing financial protection in case of accidents:

  • Liability Insurance: Texas mandates a minimum liability coverage of $750,000 for commercial trucks. However, trucks transporting hazardous materials require higher coverage, often up to $5,000,000, due to increased risks.
  • Additional Coverage for Cargo and Collision: Many companies carry extra insurance for cargo, collision, and comprehensive coverage to mitigate potential risks and ensure compliance with shippers’ requirements.
  • Proof of Insurance: Drivers must carry proof of insurance in the vehicle, and trucking companies must keep up-to-date insurance records for verification by regulatory agencies.

DOT Regulations and Reporting

Trucking companies in Texas must adhere to both state and federal DOT regulations, ensuring safety and compliance across the board:

  • FMCSA Compliance: Texas trucking companies must also comply with Federal Motor Carrier Safety Administration (FMCSA) regulations, including electronic logging devices (ELDs) to track HOS, and drug and alcohol testing for CDL holders. There is also a way to report DOT violations anonymously online, which comes in handy for some truckers. 
  • Violation Reporting: Both drivers and the public can report safety violations through anonymous hotlines or online reporting systems. This system enables transparency and accountability.
  • CSA Scores and Accountability: The FMCSA assigns Compliance, Safety, and Accountability (CSA) scores to trucking companies, reflecting their safety performance. A high CSA score can lead to audits or restrictions and may harm the company’s reputation.
  • Electronic Logging Devices (ELDs): ELDs help enforce HOS rules, track driving time, and provide accurate records for DOT inspections, ensuring that drivers stay within legal limits.

Texas DOT Hours of Service (HOS) Regulations

Hours of Service regulations in Texas govern how long truck drivers can be on duty within state lines:

  • Intrastate vs. Interstate Rules: Texas allows slightly longer intrastate hours than federal rules for interstate driving, giving drivers flexibility for in-state deliveries.
  • 12-Hour Driving Limit: Texas permits a 12-hour driving window within a 15-hour on-duty shift for intrastate hauls.
  • Rest and Break Requirements: Drivers must take an 8-hour rest before starting a new shift, and a 30-minute break is required after 8 hours of driving.
  • Weekly Limits and the 34-Hour Restart: Drivers cannot exceed 70 hours in 8 days, with a mandatory 34-hour break to reset their hours.

Additional Texas Trucking Rules and Regulations

Other Texas-specific rules add further safety and operational guidelines:

  • Special Maintenance and Repair Requirements: Trucks must undergo regular pre-trip and post-trip inspections, with yearly inspections to ensure compliance.
  • Exemptions for Special Situations: Texas grants exemptions for agricultural and emergency transport drivers, easing restrictions during specific periods or crises.
  • Electronic Logging Devices (ELDs): ELDs are required for precise HOS tracking, making it easier for companies to comply with regulations and avoid violations.

By following these requirements, Texas-based trucking companies and drivers uphold essential safety standards, help reduce road risks, and support a smoothly functioning transportation system across the state.
