Texas commercial trucks operate under both federal and state regulations. The Federal Motor Carrier Safety Administration (FMCSA) creates nationwide safety standards that apply to all trucks crossing state lines.
Texas then adopts these federal rules through the Texas Department of Public Safety and adds its own requirements for trucks operating only within the state.
The regulations apply to commercial motor vehicles over 10,001 pounds, vehicles carrying hazardous materials, and those transporting 16 or more passengers.
The regulations cover every aspect of trucking operations:
- Driver qualifications: CDL requirements, medical fitness, and training standards.
- Vehicle standards: Size limits, weight restrictions, and mandatory safety equipment.
- Operating rules: Hours of service limits, speed regulations, and route restrictions.
- Safety compliance: Inspection requirements, maintenance records, and drug testing.
How Federal and Texas Rules Work Together
Texas has adopted most federal trucking regulations into state law through the Texas Administrative Code. This means federal safety standards apply to both interstate trucks (crossing state lines) and intrastate trucks (staying within Texas). You’ll find these rules in Title 37, Chapter 4 of the Texas Administrative Code.
As an experienced truck accident attorney in Texas, when I investigate a truck accident, determining whether the driver was operating interstate or intrastate helps identify which specific rules applied. This distinction can be critical in proving violations that led to the crash.
What Are the Hours of Service for Texas Truck Drivers?
Hours of service rules limit how long truck drivers can work and drive without rest. These laws exist because driver fatigue is a leading cause of serious truck accidents. The specific limits depend on whether the driver operates interstate or only within Texas.
Federal rules permit interstate drivers 11 hours of driving after 10 consecutive hours off duty. They are also subject to a 14-hour on-duty limit and must take a 30-minute break after 8 hours of driving.
Texas intrastate drivers have different limits that allow 12 hours of driving after 8 hours off duty. They face a 15-hour on-duty limit but do not need the mandatory 30-minute break. Neither type of driver may exceed 70 hours on duty in any 7-day period.
What Is the Texas 70/7 Rule?
The 70/7 rule limits drivers’ total on-duty time within any seven-day period. This applies to both interstate and intrastate drivers in Texas. “On duty” includes all work time, not just driving time.
Drivers can reset their 70-hour clock by taking 34 consecutive hours off duty. This is called a “restart” and allows them to begin a new 7-day cycle. Violating this rule is serious evidence of negligence that I often find in truck accident cases.
How Many Hours Can You Drive Under Texas Law?
Interstate drivers may drive a maximum of 11 hours after 10 hours off duty. Texas intrastate drivers may drive up to 12 hours after 8 hours off duty. These are consecutive driving limits, not total work hours.
Do Intrastate Drivers Need ELDs in Texas?
Yes, most Texas intrastate drivers are required to use Electronic Logging Devices as of 2023. An ELD is a device that connects to the truck’s engine and automatically records driving time. This prevents drivers from falsifying paper logs to hide hours of service violations.
Limited exceptions apply to drivers operating vehicles manufactured before model year 2000 and to drivers who use paper logs for 8 days or fewer in any 30-day period. Certain agricultural operations located within 150 air miles also qualify for exemptions.
ELD data is crucial evidence after a truck accident because it provides an indisputable record of the driver’s activities. At Perrin Law PLLC Injury & Accident Lawyer, I immediately request preservation of this data because it often reveals hours of service violations that prove driver fatigue contributed to the crash.
What CDL Is Required in Texas and What Causes Disqualification?
A Commercial Driver’s License is required to operate large trucks in Texas. The vehicle’s class depends on its weight and configuration; Class A applies to combination vehicles over 26,001 pounds, such as tractor-trailers. Class B covers single vehicles over 26,001 pounds, such as dump trucks. Class C covers smaller vehicles carrying hazardous materials or 16+ passengers.
Drivers must be at least 18 for intrastate operations and 21 for interstate operations. They must pass written and driving tests and maintain a clean driving record.
Major disqualifications include:
- DUI/DWI: CDL holders are subject to a 0.04% blood alcohol limit, which is half the regular limit.
- Leaving accident scenes: Automatic one-year disqualification.
- Using CMV to commit felonies: Immediate license loss.
- Multiple major offenses: Can result in lifetime disqualification.
Even off-duty violations in personal vehicles can affect CDL status. After accidents, I always verify the driver had proper licensing and check their qualification file for past violations.
What Inspection and Maintenance Rules Apply to Texas CMVs?
Commercial trucks must undergo systematic inspections and maintenance to ensure road safety. Both drivers and motor carriers share this responsibility under Texas and federal law.
Drivers must conduct pre-trip inspections before every trip, checking brakes, steering, lights, tires, and other critical safety components. They must also complete post-trip reports documenting any defects discovered during their trip.
Motor carriers must ensure annual inspections by certified inspectors and maintain detailed records of all repairs and maintenance. Key inspection areas include:
- Brake systems: Including air lines and connections.
- Steering mechanisms: Ensuring proper alignment and response.
- Lighting and reflectors: Visibility for other drivers.
- Tires: Adequate tread depth and proper pressure.
- Coupling devices: Secure connections between truck and trailer.
These records must be retained for at least one year while the vehicle is in service plus six months. When I handle truck accident cases, I immediately subpoena these records to determine if mechanical failures or negligent maintenance contributed to the crash.
What Are Texas Size and Weight Limits and When Are Permits Required?
Texas enforces strict size and weight limits to protect roads, bridges, and public safety. The standard maximum gross vehicle weight is 80,000 pounds on interstate highways. Individual axle limits also apply to distribute weight properly.
Standard weight limits include:
- Single axle: 20,000 pounds maximum.
- Tandem axle: 34,000 pounds maximum.
- Triple axle: 42,000 pounds maximum.
Size limits are 14 feet high, 8 feet 6 inches wide, and varying lengths depending on vehicle configuration. Single vehicles may not exceed 45 feet, while semitrailers are limited to 59 feet.
Loads exceeding these limits require special oversize or overweight permits from the Texas Department of Motor Vehicles. These permits specify approved routes and may require escort vehicles for extremely large loads. Overweight trucks cause more severe accidents because they take longer to stop and create greater impact forces.
What Cargo Securement Rules Apply in Texas?
Texas follows federal cargo securement standards to prevent loads from shifting, falling, or causing rollovers. Improperly secured cargo is a major cause of truck accidents and can create liability for both drivers and carriers.
Cargo must be secured to prevent movement during normal driving conditions. The working load limit of all tie-downs must be at least 50% of the cargo’s weight. Different cargo types have specific securement requirements.
Common securement methods include:
- Chains and binders: For heavy equipment and machinery.
- Straps and webbing: For general freight shipments.
- Blocking and bracing: To prevent movement within the trailer.
- Tarps: Required for loose materials that could blow off.
Special rules exist for logs, pipes, vehicles, and heavy machinery. Carriers cannot escape liability by blaming loading crews if they failed to inspect and properly secure the load before departure.
Do Texas Trucks Have Different Speed or Operating Rules?
Texas does not have a statewide lower speed limit for trucks. Commercial vehicles can legally travel at posted speed limits unless specific highways post lower truck speeds. This differs from many states that impose blanket truck speed restrictions.
However, trucks face other operating restrictions:
- Left lane limitations: Many highways prohibit trucks from the far left lane.
- No-truck routes: Some roads ban commercial vehicles entirely.
- Bridge restrictions: Based on height and weight limitations.
- Following distance: Trucks must maintain greater distances than cars.
Some regulations and safety guidelines discourage coasting in neutral on downgrades and advise truck drivers to use hazard lights when traveling well below normal highway speeds. While Texas doesn’t broadly restrict truck speeds, safe speed depends on conditions regardless of posted limits.
What Are the Drug and Alcohol Testing Rules for CDL Holders?
CDL holders face much stricter drug and alcohol rules than regular drivers. Commercial drivers are held to a stricter blood alcohol standard than regular drivers. This lower threshold reflects the greater responsibility of operating large, dangerous vehicles.
Required testing situations include pre-employment screening, random testing throughout the year, reasonable suspicion testing, post-accident testing, and return-to-duty testing after violations. The standard DOT drug panel tests for marijuana, cocaine, amphetamines, opioids, and PCP.
Positive tests result in immediate removal from safety-sensitive duties and go into the FMCSA Clearinghouse database that all employers must check. Even legal prescriptions can disqualify drivers if they impair safe operation.
After accidents, I always investigate testing compliance and request post-accident test results. Substance use violations dramatically strengthen injury claims and often lead to substantial settlements.
What Insurance Minimums Apply to Motor Carriers?
Federal law requires much higher insurance minimums for commercial trucks than regular vehicles because trucks cause more severe damage in accidents. General freight haulers must carry at least $750,000 in liability coverage. Hazardous materials carriers are required to maintain $1 million to $5 million in financial responsibility, depending on the materials transported.
These minimums often prove inadequate for serious crashes involving multiple vehicles or catastrophic injuries. Many responsible carriers maintain higher liability coverage than the legal minimum for general freight operations.
Coverage types include primary liability for damages to others, cargo insurance for shipped goods, and physical damage coverage for the truck itself. Understanding available insurance is crucial for ensuring full compensation after serious truck accidents.
What Records Must Carriers Keep in Texas?
Texas requires motor carriers to maintain detailed records that often provide crucial evidence after accidents. Driver qualification files must be kept for three years and include the driver’s application, road test, medical certificate, and violation history.
Electronic logging device (ELD) data must be preserved for six months, while vehicle maintenance records must be retained for one year during service plus an additional six months afterward. Accident reports must be retained for three years, while drug and alcohol test results have retention periods ranging from one to five years.
After an accident, I immediately send preservation letters demanding carriers maintain all records beyond normal retention periods. Destroying records after receiving such notice can lead to court sanctions and strengthen your case significantly.
Who Enforces Trucking Laws in Texas?
Several agencies enforce trucking regulations in Texas. The Texas Department of Public Safety Commercial Vehicle Enforcement division conducts roadside inspections and traffic enforcement. The FMCSA handles interstate carrier oversight and major crash investigations.
Local police and sheriff’s departments respond to accidents and enforce traffic laws. The Texas Department of Motor Vehicles handles registration, permits, and carrier credentials. These agencies conduct over 100,000 roadside inspections annually in Texas.
Violations can result in fines, out-of-service orders, and poor safety ratings that affect a carrier’s ability to operate. Serious violations may lead to criminal charges. Even if no citations were issued, injured victims should consult an attorney to determine whether they have grounds for a civil claim.
How Do Rule Violations Prove Negligence After a Truck Crash?
Violating safety regulations is “negligence per se” under Texas law. This means the violation automatically proves negligence if it contributed to the crash. You don’t need to prove the defendant should have known better, the law already established the standard of care.
Common violations that prove negligence include hours of service violations showing driver fatigue, failed inspections demonstrating known dangerous conditions, improper cargo securement proving failure to follow industry standards, and employing unqualified drivers showing negligent hiring.
My investigation process includes obtaining police reports, subpoenaing driver logs and maintenance records, downloading electronic data from the truck, interviewing witnesses, and hiring experts to reconstruct the accident. Multiple violations often exist in serious cases, creating multiple counts of negligence.
Trucking companies deploy rapid response teams to accident scenes to protect their interests. This is why contacting a personal injury attorney quickly helps preserve evidence before it disappears or gets destroyed.
