Oilfield Trucking and Hot Shot Accidents: Where the Highway Meets the Lease Road

By Guy Muller  ·  Injury lawyer, San Antonio  ·  Updated July 2026

The short and plain version

  • Crashes are the number one cause of death for oil and gas workers. According to OSHA, vehicle wrecks account for almost half of the deaths in upstream oil and gas.
  • The danger extends well beyond the rig. It is on the two-lane lease roads and the highways, on flatbeds, hot shots, sand haulers, water trucks, crude tankers, and rig-move trucks.
  • Federal "hours-of-service" rules limit how long a driver can be behind the wheel. But the oil and gas industry has special exemptions that allow longer hours than almost any other industry.
  • A worn-out driver on no sleep after a double tour does not happen because of sheer bad luck. It usually happens because it is a byproduct of what that schedule was built to produce.
  • An oilfield service company that runs trucks is held to trucking-safety rules, even if it does not call itself a "trucking company."
  • After a crash, the driver and his company can both be on the hook for the damages they cause. So can the company that loaded or scheduled the run. These cases hinge on evidence that disappears fast.

1. Why crashes are the number one oilfield killer

The most dangerous part of an oilfield job is often the drive to it and the drive back home. The rig gets the safety meetings. But the road, at 2 a.m., on no sleep, and on a two-lane highway crowded with sand trucks, gets nothing.

That is not an opinion. It is what the actual federal government’s own numbers say, year after year. Everybody pictures the rig floor when they think about oilfield danger, the pipe, the pressure, the heights, the chain spinning, etc. But the thing most likely to kill an oil and gas worker is a vehicle on a public road.

By the numbers Almost half

Crashes are the number one killer of oil and gas workers.

OSHA reports that traffic incidents are "the number one cause of fatalities in the upstream oil and gas industry," accounting for almost half of all deaths, and that most of them happen on public roads. The federal researchers who track these deaths case by case found the same thing. Of 470 oil and gas worker deaths they identified from 2014 through 2019, vehicle incidents were the most frequent cause. And about three of every four workers killed were contractor employees.

Sources: OSHA, Oil and Gas Well Drilling and Servicing eTool, "Common Wellsite Incidents and Fatalities." osha.gov. CDC/NIOSH, Morbidity and Mortality Weekly Report, "Fatalities in Oil and Gas Extraction Database, United States, 2014 to 2019" (2023). cdc.gov

And the workers are not the only ones paying the price. The trucks share those roads with school buses, grandparents, teachers, ranch trucks, and families heading to town. When a company puts a worn-out driver in a heavy truck on a dark farm-to-market road, it is not making a confined private business decision. Instead, it is making a much larger decision about the safety of everybody on that road.

By the numbers 1 in 4

One in four Texas traffic deaths happens in an energy production area.

In 2024, the Texas Department of Transportation counted nearly 79,000 crashes in the state's five major energy regions, killing 1,023 people, one in four of all traffic deaths in Texas that year. The Permian Basin alone had 25,309 crashes with 320 deaths and 915 serious injuries. The Eagle Ford Shale had 14,518 crashes with 173 deaths and 598 serious injuries. TxDOT names the leading causes: failure to control speed and driver inattention.

If you want the county-by-county picture of where this happens in South Texas, it is in the Eagle Ford Shale injuries guide. The West Texas version is in the Permian Basin guide.

None of this is a mystery to the companies. They know the numbers better than anybody, because they insure against them. The question this page answers is what the law says about it, and who has to answer when the math catches up with your family.

2. The oilfield trucking world

To understand an oilfield truck crash, it helps to understand how much of the oilfield is really a trucking operation.

Almost everything a well needs arrives on a truck, and almost everything it produces leaves on one, too. Flatbeds haul pipe, tools, and equipment. Frac sand haulers run load after load, because a frac job eats sand by the trainload and every grain of it arrives on a truck. Water trucks haul fresh water in and produced water (the salty wastewater that comes up with the oil) out to disposal wells, on runs that really never stop. Crude haulers pull tanker loads from the tank battery to the pipeline. And when a rig finishes a hole, a rig-move convoy of heavy-haul trucks tears it down and carries it to the next location.

Then there are the hot shots.

Plain English: "hot shot"

A "hot shot" is a smaller trucking rig, usually a heavy-duty pickup (often a one-ton dually) pulling a flatbed gooseneck trailer, hired to run parts, tools, or equipment to a lease fast. The name tells you the job: something broke, the rig is losing money by the hour, and somebody needs that part right now. Hot shot drivers are often owner-operators paid by the load. The only way to earn more is to drive more.

Now put all the pieces together. Drivers paid by the load or by the hour, so the pressure always points toward more miles. High turnover, so there are always green drivers learning the ropes. Heavy, sometimes overloaded trailers. Caliche lease roads dumping onto two-lane farm-to-market highways that were never built for this kind of traffic. Late night runs, because the well does not sleep. That is the world these wrecks are born from. An oilfield truck crash is almost never just “an accident.” Somewhere behind it there is a schedule, a dispatch record, and a set of bad choices.

3. Fatigue and the hours-of-service rules, including the oilfield exemptions

Congress and federal regulators figured out a long time ago that tired truck drivers kill people. So federal law fortunately limits how long a commercial driver can drive and work. Those limits are called the “hours-of-service” rules.

Plain English: "hours of service"

"Hours of service" are the federal limits on a truck driver's time, found in 49 CFR Part 395. The basics for freight drivers: after 10 straight hours off duty, a driver gets a 14-hour work window and can drive up to 11 hours inside it. Driving must stop for at least a 30-minute break after 8 hours behind the wheel. And there are weekly caps: 60 hours in 7 days, or 70 hours in 8 days for companies that run every day. A driver can "restart" that weekly clock by taking 34 straight hours off.

Those are the rules for almost every commercial truck driver in America. But the oil and gas industry got itself something real special.

Plain English: "the oilfield exemptions"

Buried in the hours-of-service rules, at 49 CFR 395.1(d), are two exceptions just for oilfield work. The 24-hour restart: drivers hauling oilfield equipment or servicing oil and gas field operations can restart their work week after only 24 hours off, instead of the 34 hours everyone else needs. The "oilfield waiting time" rule: for specially trained drivers of trucks specially built to service wells (think wireline trucks, frac pumps, cement pumps), the hours spent waiting at the well site do not count toward the 14-hour work window at all. The waiting time gets logged as "off duty," even though the driver is sitting on location, responsible for the equipment, and not free to leave. The rule itself sets no outer cap on how many hours of waiting time can be excluded.

Read that last part again, because it is incredibly important. A regular freight driver’s day caps out at 14 hours. But a waiting-time driver can sit at a frac job for six or eight hours, “off duty” in the eyes of the log book, and then legally drive. His real day, the hours since he last slept in a bed, can stretch far past anything the normal rules would allow. But the body and brain do not care what the log book says. The body and brain get tired.

These exemptions did not come from a safety study. The industry asked for them back in 1962, and it got them, and they have survived every reform since. And there is a hard line here that the industry does not always respect. FMCSA guidance interpreting this exemption has stated that ordinary trucks hauling sand, water, and supplies to and from the well do not qualify merely because the truck was modified or the driver received some extra training; the exemption is reserved for vehicles that are specially constructed to service wells and drivers who are specially trained to operate them. So when a sand hauler’s company treats his waiting time as free hours, that is not a loophole. That may be a violation dressed up as one.

And Texas built its own version on top. For trucks that stay inside the state, Texas adopts the federal safety rules through the Department of Public Safety under Texas Transportation Code Chapter 644. But Texas sets its own numbers in 37 Texas Administrative Code 4.12: up to 12 hours of driving after 8 hours off, no driving after the 15th hour on duty, and a 70-hour cap in any 7 days. Texas oilfield drivers get a 24-hour restart too. Different math, same special treatment for the oil patch.

So here is the blunt and direct summary. The law knows tired drivers kill. That is the whole reason the limits exist. And yet the oil patch still runs on the loosest fatigue rules of nearly any industry on the road. When a driver crashes on no sleep after a double tour, that is not bad luck. That is the output of a schedule somebody built, under rules somebody lobbied for, to keep the wells running, producing, and making more money without paying for more drivers.

4. When a service company is really a trucking company

Ask an oilfield service company what business it is in and it will probably say fracking, or wireline, or water hauling, or well servicing. Almost none of them will say “trucking.” But the law cares more about what the company does, not what they call themselves.

The federal safety rules apply to a “motor carrier,” and that term covers both for-hire trucking outfits and “private” carriers, meaning companies that run their own trucks to support their own business. Under the federal definitions in 49 CFR 390.5, a commercial motor vehicle is, in general, any truck weighing or rated at 10,001 pounds or more and used across state lines. A truck and its trailer count together. So this is not just the eighteen-wheelers. It covers most hot shot rigs pulling a loaded gooseneck. For runs that stay inside Texas, the state applies the same body of rules to the bigger rigs, generally those over 26,000 pounds, plus anything hauling placarded hazardous materials.

And here is a detail that surprises people. A driver does not even need a commercial driver’s license (a CDL) for many of these rigs. The CDL requirement generally starts at 26,001 pounds. The safety rules start at 10,001. A lot of hot shot operations live in that gap: drivers with no special license, hauling heavy loads for money, still bound by federal safety rules their company may never have taught them.

So a frac company running pump trucks down the highway is a trucking company in the eyes of the law. A water hauling outfit is a trucking company. A well-servicing company moving its own rigs is a trucking company. That means driver qualification files, drug and alcohol testing, inspection and maintenance records, and hours-of-service logs, the whole framework that exists because heavy trucks kill people when those things get skipped. Most of these companies quietly admit it, usually only inside their own driver handbooks, which acknowledge the federal rules and the Texas commercial driver standards.

There is one more piece of this that companies hate, and you should know it by name.

Plain English: "statutory employee"

Under the federal safety rules, the definition of "employee" in 49 CFR 390.5 includes a driver of a commercial motor vehicle "including an independent contractor while in the course of operating a commercial motor vehicle." Lawyers call this the "statutory employee" rule. In plain words: a carrier usually cannot hand a driver a 1099, call him an independent contractor, and use that label to duck responsibility for what happens on the road. For safety purposes, the law treats the driver as the carrier's employee anyway.

Texas courts have applied this in real cases. In Morris v. JTM Materials, Inc., a Fort Worth court of appeals held that an interstate motor carrier is vicariously liable as a matter of law (automatically responsible) for the negligence of the statutory-employee driver of a truck it had leased. And because the carrier had never checked the driver’s history, the court also reversed a summary judgment on the negligent hiring and entrustment claims against the carrier and sent those claims back so a jury could decide them. The paperwork said one thing. The law looked at who controlled the truck.

Why does this matter to you? Because the oilfield runs on layers of contractors, subcontractors, owner-operators, and leased trucks, and after a wreck every company in that stack reaches for the same first move: he was not our employee. The statutory-employee rule exists precisely because that move was being used to put dangerous trucks on the road with nobody answering for them.

5. Who is responsible after an oilfield truck crash

Let’s start with the baseline. When a working driver hurts somebody on the job, Texas law generally makes the employer answer for it. Lawyers call it “respondeat superior” (a Latin phrase that just means the boss answers for the worker). To use it, you have to show the driver was an employee doing his work, in the “course and scope” of the job, not off on some errand of his own, when the wreck happened.

From there, the list of companies that may have to answer gets longer, depending on the facts:

  • The driver, for the driving itself: speed, following distance, lane changes, phone use, driving exhausted.
  • The driver’s employer or the motor carrier, automatically for an on-the-job driver’s negligence, and under the statutory-employee rule even for many “independent contractor” and leased-truck setups.
  • The carrier in its own right, if it hired a driver it knew or should have known was unfit, handed him the truck anyway, skipped the record checks the federal rules require, or worked him past the hour limits. Texas law calls these claims negligent hiring and negligent entrustment.
  • The company that loaded the truck, in some cases, if an overloaded or badly secured load caused or worsened the wreck.
  • The company that controlled the schedule, in some cases. In the oilfield, the pressure to run a load at 3 a.m. often comes from above the driver, and sometimes from above his employer. Whether that rises to legal fault depends on the facts and the contracts.
  • A maintenance shop or manufacturer, if brakes, tires, or coupling gear failed.

One piece of good news inside a hard subject. The shield you may have read about in the Chapter 95 guide protects property owners in one specific setting. It covers claims by contractors’ workers hurt while working on an improvement on the owner’s property. A crash out on a public highway is usually a different animal, governed by ordinary negligence and trucking law, not Chapter 95. But the same stack of companies and contracts still decides who defends and who pays, so mapping that stack is still job one.

You should also know the trucking industry rewrote part of the Texas rulebook in its own favor, and recently. In 2021 the Legislature passed House Bill 19, a law the commercial trucking lobby pushed hard for, now sitting in Chapter 72 of the Civil Practice and Remedies Code. In plain words: in a commercial vehicle crash case, the defendant can demand a split trial. The first phase decides fault and ordinary compensation. Claims aimed at the company’s own conduct largely wait for a second phase. And if the company timely stipulates (formally admits) that the driver was its employee acting within the scope of employment, its liability for ordinary negligence claims like negligent entrustment is based only on respondeat superior, and the claimant generally cannot introduce separate negligent-entrustment evidence in the first phase. The Legislature did leave a door open on specific safety facts: even in the first phase, the statute lists things like whether the driver was properly licensed, medically certified, or driving in violation of the hours-of-service rules, federal or Texas. This is not a page about tactics, so I will say only this. HB 19 changed the procedure, not the truth, and it is one more reason the lawyer you pick needs to actually know trucking law.

What Texas courts have said

A short, plain summary of Texas decisions that shape oilfield trucking cases. This is legal background, not a prediction about any specific case.

  • Otis Engineering Corp. v. Clark (1983). A supervisor sent an obviously intoxicated worker home, and the worker caused a wreck that killed two people. The Texas Supreme Court held that when an employer, because of a worker's incapacity, takes control of that worker, it must act as a reasonably prudent employer to keep him from putting others at unreasonable risk.
  • Nabors Drilling, U.S.A., Inc. v. Escoto (2009). An oilfield worker crashed driving home after a 12-hour night shift. The Court held that employers generally owe no duty to others for what off-duty workers do away from the job, unless the employer knew the worker was impaired and affirmatively took control of the situation. Setting hard schedules is not, by itself, that kind of control, and the Court declined to require employers to train workers about the well-known dangers of driving tired.
  • Painter v. Amerimex Drilling I, Ltd. (2018). A driller was assigned, as part of his job duties under the drilling contract, to drive his crew between the rig and company housing, and a crash on that drive killed and hurt crew members. The Court confirmed the "coming-and-going" rule, that an ordinary commute is outside the course and scope of the job. But the rule does not apply when the travel itself is a regular or specially assigned duty done for the employer's benefit. And employee status turns on the employer's overall right of control, not a task-by-task analysis.
  • Morris v. JTM Materials, Inc. (Fort Worth 2002). Under the federal motor carrier rules, the court held that an interstate carrier is vicariously liable as a matter of law for the negligence of the statutory-employee driver of its leased equipment, and reversed summary judgment on the negligent hiring and entrustment claims so a jury could decide whether the carrier's failure to check the driver's record was a proximate cause of the crash.
  • Schneider v. Esperanza Transmission Co. (1987). The Court set out the elements of negligent entrustment: handing a vehicle to an unlicensed, incompetent, or reckless driver the owner knew or should have known was unfit, plus negligence by that driver causing the wreck. There must also be a real connection between what made the entrustment careless and what actually caused the crash.

The plain takeaway: if the driver who hit you was on the clock, the company usually answers for him, and the real fights are over labels, course and scope, and who controlled the run. If the driver was a worn-out worker driving himself home, the law is far less friendly. Which side of that line a case falls on is exactly what a qualified lawyer sorts out early, while the logs, the electronic driving data, and the dispatch records still exist.

Plain English: "MCS-90"

An "MCS-90" is a federal endorsement (an add-on page) that federal law requires on many trucking companies' insurance policies. It is a promise to the public: if the carrier is found liable for a crash, money will be there, even if the insurance company might otherwise have an out under the policy. The required minimums are $750,000 for ordinary freight, $1,000,000 for oil and most other hazardous materials, and $5,000,000 for certain bulk shipments of the most dangerous materials. Those numbers were set in 1985 and have not moved since, which tells you who has been winning in Washington. How the layers of trucking and oilfield insurance fit together, and why the MCS-90 can decide whether a judgment is worth anything, is covered in the insurance coverage guide (coming soon).

6. What this means for you and your family

What this means for you and your family

Here is the plain version of everything above.

If an oilfield truck hurt you or took someone you love, the odds are high that the wreck was the last link in a chain of choices: a schedule that ignored sleep, an exemption stretched past what the law allows, a driver nobody vetted, a truck nobody maintained, a label used to dodge responsibility. More than one company may have to answer for that. The companies know it, which is why their adjusters and lawyers move fast.

Two things disappear quickly after a truck wreck: the evidence and your bargaining power. Electronic driving records, hours-of-service logs, dispatch messages, and truck data do not keep themselves forever. And the first offer usually arrives before anyone knows what your injuries really are. Do not let anyone rush you into signing anything, and be careful what you say to an insurance adjuster whose job is to close your claim cheap.

One more thing, because it is true and nobody says it. The driver who hit you may be a working man who was taken advantage of by the same system, driven past exhaustion by somebody who made way more money than he did and slept in a bed that night. You can hold the companies responsible without pretending the driver is the whole story. In fact, the companies would prefer you blame only the driver. Do not do them the favor.

7. Questions to ask any lawyer you are considering

You do not have to take anybody’s word, including mine. Test any lawyer you talk to. These questions will tell you quickly whether they know oilfield trucking work.

Questions to ask before you hire a lawyer for an oilfield truck crash case
  • Ask what the hours-of-service rules are, and what the oilfield exemptions do to them. If they have never heard of the waiting-time rule, that tells you something.
  • Ask how fast they will act to preserve the electronic driving data, the logs, and the dispatch records, and what happens to that evidence if nobody asks for it.
  • Ask what a "statutory employee" is, and what it means when the company says the driver was an independent contractor.
  • Ask what House Bill 19 changed about trucking cases in Texas, and how it affects a case like yours.
  • Ask what an MCS-90 is and how they would find every layer of insurance on the truck, the trailer, and the companies above them.
  • Ask about their experience with oilfield and trucking cases, whether they work with experienced co-counsel when needed, how the fee works, what expenses they cover up front, and what happens if the case does not recover.

A lawyer who knows this work will not be bothered by those questions.

Common questions

Why are oilfield roads so dangerous? +

Because the oilfield puts heavy trucks, long hours, and narrow country roads together, day and night. OSHA reports that traffic crashes are the number one killer in upstream oil and gas. They cause almost half of all deaths in that part of the industry. And workers are not the only ones at risk. In 2024, one in four of all Texas traffic deaths happened in the state's energy production areas, according to TxDOT.

What are hours-of-service rules? +

They are the federal limits on how long a truck driver can drive and work. In plain terms: after 10 hours off, a driver gets a 14-hour work window and can drive up to 11 hours inside it. A 30-minute break is required along the way, and there are weekly caps of 60 or 70 hours. Texas has its own version for trucks that stay inside the state, with slightly different numbers. These rules exist because tired drivers kill people.

What is the oilfield exemption? +

It is a pair of special exceptions to the hours-of-service rules, just for oil and gas work. One lets oilfield drivers restart their work week after only 24 hours off instead of 34. The other says that for specially trained drivers of specially built well-servicing rigs, the hours spent waiting at the well do not count toward the driving-day limit. The result is that some oilfield drivers can legally be on a job far longer than almost any other truck driver in America.

Can I sue if a fatigued oilfield driver hit me? +

Often, yes. If the driver was working at the time, on a run for the company, the company usually answers for what its driver does on the job. If the driver was on his way home after a long shift, Texas law is much tougher on that claim, though there are exceptions when the employer, because of a known incapacity, takes an affirmative act of control over the employee, such as sending him home. Which side of that line your case falls on is a fact question, and it is one of the first things a qualified lawyer will figure out.

Is a hot shot driver covered by trucking rules? +

Usually, yes. The federal safety rules apply when the truck and trailer together weigh or are rated at 10,001 pounds or more and the run crosses state lines. That covers most one-ton hot shot rigs pulling loaded gooseneck trailers. Runs that stay inside Texas fall under the state's own rules for heavier rigs. The name on the door does not matter. The rules follow the truck.

Who is responsible besides the driver? +

Often several companies at once. The driver's employer or the motor carrier operating the truck usually answers for the driver's negligence. A carrier that put an unfit driver behind the wheel, or leased the truck, can be on the hook for its own choices too. And depending on the facts, the company that loaded the truck, maintained it, or scheduled the run can share responsibility too. Finding every responsible company is one of the first jobs in any oilfield truck crash case.

What is an MCS-90? +

It is a federal endorsement, an add-on page, attached to a trucking company's insurance policy. It is a promise to the public that money will be there if the carrier is found liable for a crash, even when the insurance company might otherwise have a way out. Federal law sets the minimum at $750,000 for ordinary freight, $1,000,000 for oil and most other hazardous materials, and $5,000,000 for certain bulk shipments of the most dangerous materials. It matters most when a trucking company is small, uninsured in practice, or gone by the time the case ends.
