A trailer disconnect crash is one of the most violent and unpredictable events that can happen on a Charleston-area road. When a pickup truck loses its trailer at highway speed on Interstate 26 near Summerville, on US Highway 17 through the Lowcountry, or on a two-lane road near Johns Island, the result is a multi-ton projectile with no driver, no brakes, and no warning. These crashes cause serious physical injuries, and they are almost always preventable.

What Causes a Trailer to Disconnect from a Pickup Truck

Trailer disconnect crashes happen when the connection between a pickup truck and its trailer fails completely. Among the primary causes of severe towing crashes, trailer detachment, safety chain failure, and improper loading stand out as the most common preventable mechanical and operational failures.

The most frequent cause is an improperly secured ball hitch. If the hitch ball is the wrong size for the coupler, or if the locking latch is not fully engaged, the trailer can bounce free over a pothole or bump. This happens all the time on Charleston’s older roads, including stretches of Savannah Highway and the connector roads near North Charleston.

Worn or corroded hitch hardware is another major factor. Metal fatigues over time, especially in the Lowcountry’s humid, salt-air environment. A hitch that looks fine on the outside can be structurally compromised. Pickup truck owners who use their trucks for work, such as landscapers, contractors, and utility crews throughout the Charleston metro area, often skip regular equipment inspections.

Safety chains, which are intended to provide a secondary attachment between the trailer and tow vehicle in the event of hitch failure, are commonly cited as either improperly connected or insufficient to prevent trailer separation once the primary coupling fails. Under South Carolina Code Section 56-5-5150, when a vehicle is towing another vehicle on a public road or highway, the towing vehicle must be attached to the towed vehicle by a safety chain, cable, or equivalent device in addition to the regular drawbar, tongue, trailer hitch, or other connection, and those safety connections must be of sufficient strength to maintain connection under all conditions while the towed vehicle is being pulled.

Overloading is a contributing factor as well. A trailer loaded beyond the pickup truck’s rated towing capacity puts enormous stress on the hitch assembly. South Carolina Code Section 56-5-4900 also requires that farm trailers exceeding 8,000 pounds gross weight be secured by a pintle hook, spring-load latch, safety lock hitch pin, or equivalent mechanism, and that safety chains be secured by a spring-loaded latch or other mechanism to ensure positive closure under loaded, operating conditions. When drivers ignore these requirements, disconnects become far more likely.

The Physical Dangers a Disconnected Trailer Creates on the Road

Once a trailer separates from a pickup truck, it becomes a completely uncontrolled hazard. A detached trailer may enter adjacent traffic lanes, creating high-severity crash conditions. Other drivers have no time to react, especially at highway speeds on I-26 or US-17.

The disconnected trailer does not simply stop. It continues forward under its own momentum. Depending on its weight and the road surface, it may jackknife, roll over, or careen across multiple lanes. A fully loaded utility trailer or boat trailer can weigh several thousand pounds. When it strikes a passenger car, the results are catastrophic.

Pedestrians and cyclists near roadways face extreme danger as well. Near the Battery, along the West Ashley Greenway, or on any of the bike routes connecting Charleston’s neighborhoods, a runaway trailer can reach areas that drivers would never expect.

The towing vehicle itself also becomes dangerous immediately after the disconnect. The sudden loss of the trailer’s weight causes the pickup truck’s rear end to lift. The driver may lose control, veer into oncoming traffic, or slam the brakes and cause a rear-end collision with vehicles behind them. Loss of control due to trailer sway represents another significant factor, and trailer sway typically occurs when weight distribution is improper or when trailers are operated at speeds that exceed the stability threshold of the towing configuration.

Multi-vehicle pileups are a real and documented outcome of these events. On a busy corridor like the Don Holt Bridge approach or the merge onto I-526, a single disconnected trailer can trigger a chain reaction involving five or more vehicles.

South Carolina Law and Who Is Liable After a Trailer Disconnect Crash

Liability in a trailer disconnect crash in South Carolina can fall on more than one party. The driver of the pickup truck is the most obvious responsible party, but they are not always the only one. Identifying every liable party is critical to a full recovery for injured victims.

The pickup truck driver carries a duty to inspect the hitch connection before every trip. If that driver failed to properly secure the trailer, or chose to ignore obvious signs of wear in the hitch assembly, they breached that duty. South Carolina Code Section 56-5-5150 makes this obligation clear, and a violation of that statute is strong evidence of negligence in a civil personal injury claim.

If the driver was operating the truck as part of their job, their employer may be liable under the legal doctrine of respondeat superior. This doctrine holds employers responsible for the negligent acts of employees performed within the scope of employment. A pickup truck accident lawyer can identify whether the driver was on the clock for a landscaping company, a roofing contractor, or a construction firm operating out of the Charleston area.

The manufacturer of a defective hitch component may also share liability under South Carolina product liability law. If a hitch ball, coupler, or safety chain hardware was defectively designed or manufactured, the injured victim may have a claim against that manufacturer separate from any claim against the driver.

A maintenance shop that serviced the hitch and failed to identify or correct a dangerous defect can also be held responsible. South Carolina’s modified comparative negligence law, codified at S.C. Code Section 15-38-15, allows fault to be apportioned among multiple defendants. Under South Carolina’s modified comparative negligence system, you can recover damages if your fault is 50% or less, but you cannot recover if your fault is 51% or more.

Injuries Commonly Caused by Trailer Disconnect Crashes in Charleston

The injuries from a trailer disconnect crash tend to be severe. The sudden, violent nature of the impact, combined with the size and weight of a runaway trailer, means that victims rarely walk away without serious harm.

Traumatic brain injuries are common. A vehicle struck by a disconnected trailer absorbs a massive force. Occupants can suffer concussions, skull fractures, and diffuse axonal injuries that affect long-term cognitive function. These injuries often require months of rehabilitation and may cause permanent disability.

Spinal cord injuries are another frequent outcome. A direct impact to the vehicle can compress or sever the spinal cord, resulting in partial or full paralysis. Even injuries that do not cause paralysis, such as herniated discs and fractured vertebrae, can cause chronic pain and limit a victim’s ability to work.

Broken bones, internal organ damage, and chest injuries are also typical in these crashes. A trailer striking the side or rear of a passenger vehicle can crush the door frame inward, trapping occupants and causing crush injuries to the legs, arms, and torso. Burn injuries can follow if a fuel line ruptures on impact.

According to NHTSA data, passenger-vehicle trailer-towing crashes resulted in an estimated 69,389 total crashes, 500 fatalities, and 25,054 nonfatal injuries in 2023 alone. These numbers reflect the real and ongoing danger that improperly secured trailers pose to everyone sharing the road. If you were injured in this type of crash near the Ravenel Bridge, along the Mark Clark Expressway, or anywhere in the Charleston area, your injuries deserve serious legal attention.

Victims who work with a truck accident lawyer after a trailer disconnect crash can pursue compensation for medical expenses, lost wages, future medical care, pain and suffering, and permanent disability through the settlement process.

What to Do After a Trailer Disconnect Pickup Truck Crash in South Carolina

The steps you take in the hours and days after a trailer disconnect crash directly affect your ability to recover damages. Acting quickly and carefully protects your rights under South Carolina law.

Call 911 immediately. A police report creates an official record of the crash, which is essential evidence in a personal injury claim. Ask responding officers to document the condition of the trailer hitch, the safety chains, and the point of separation on the roadway. The Charleston County Sheriff’s Office and the South Carolina Highway Patrol both respond to crash scenes in the Lowcountry, and their reports carry significant weight in litigation.

Photograph everything you can. Get images of the disconnected trailer, the hitch assembly, the road surface, skid marks, and all vehicle damage. If the trailer has a license plate or identifying markings, capture those too. This evidence can disappear quickly, especially if the responsible party or their insurer moves to recover the trailer before an investigation is complete.

Seek medical care right away, even if you feel fine. Adrenaline masks pain. Spinal injuries, internal bleeding, and traumatic brain injuries often present symptoms hours after the initial crash. A documented medical visit creates a clear link between the crash and your injuries, which is critical when pursuing a claim.

Do not speak to any insurance company, including your own, until you have spoken with an attorney. Insurance adjusters work to minimize payouts, and anything you say can be used to reduce or deny your claim. A personal injury lawyer can handle all communications on your behalf and ensure your rights are protected from the start.

South Carolina’s statute of limitations for personal injury claims is generally three years from the date of the crash under S.C. Code Section 15-3-530. Missing that deadline means losing your right to file suit entirely. Contact Steinberg Law Firm at 843-720-2800 as soon as possible after the crash.

FAQs About Trailer Disconnect Pickup Truck Accident Injuries in Charleston, SC

Is the pickup truck driver always responsible when a trailer disconnects and causes a crash?

Not always, but the driver is often the starting point for a liability analysis. The driver has a legal duty to inspect and properly secure the trailer before driving on any public road in South Carolina. If the driver failed to do so, they are likely negligent. However, liability can also extend to the driver’s employer if the truck was being used for work, to a manufacturer if a hitch component was defective, or to a maintenance provider who serviced the equipment and missed a dangerous defect. A full investigation is necessary to identify every responsible party.

What South Carolina law requires safety chains on trailers?

South Carolina Code Section 56-5-5150 requires that any vehicle towing another vehicle or trailer on a public road must use a safety chain, cable, or equivalent device in addition to the primary hitch connection. That safety chain must be strong enough to keep the trailer attached under all towing conditions. Farm and tobacco trailers have an additional requirement under S.C. Code Section 56-5-4900, which mandates a pintle hook, spring-load latch, safety lock hitch pin, or equivalent mechanism, plus safety chains secured by a spring-loaded latch to ensure positive closure when hauling on public roads.

How long do I have to file a lawsuit after a trailer disconnect crash in South Carolina?

In most personal injury cases in South Carolina, you have three years from the date of the crash to file a lawsuit, under S.C. Code Section 15-3-530. If you miss this deadline, you lose your right to pursue compensation in court entirely. Wrongful death claims have their own deadlines as well. Because evidence in trailer disconnect cases can disappear quickly, including the hitch hardware and the trailer itself, it is important to contact an attorney as soon as possible after the crash, not just before the deadline.

Can I still recover damages if I was partly at fault for the crash?

Yes, in many situations. South Carolina follows a modified comparative negligence rule under S.C. Code Section 15-38-15. This means your damages are reduced by your percentage of fault, but you can still recover as long as your fault does not reach 51% or more. For example, if your total damages are $200,000 and you are found 20% at fault, you could recover $160,000. If you are found 51% or more at fault, you recover nothing. Insurance companies often try to inflate a victim’s share of fault to reduce what they owe, which is one reason having an attorney involved early is so important.

What damages can I recover after a trailer disconnect pickup truck crash in Charleston?

Injured victims in South Carolina can pursue several categories of damages in a personal injury claim. These include current and future medical expenses, lost wages from time missed at work, loss of future earning capacity if your injuries affect your ability to work long-term, pain and suffering, and compensation for permanent disability or disfigurement. In cases where a death occurs, surviving family members may pursue a wrongful death claim. The specific damages available in your case depend on the nature and severity of your injuries, as well as the facts surrounding the crash. An attorney can evaluate your situation and help you understand what your claim may be worth.
