What If a Truck Accident Resulted in Hazardous Material Spillage?

Any accident that involves a big rig, tractor-trailer, or other large commercial truck is incredibly dangerous, and the crash is much more likely to cause critical injuries or wrongful death when the tractor-trailer is hauling hazardous materials. 

If a truck accident resulted in hazardous material spillage, the toxic leak or spill can potentially harm anyone near the accident scene, including residents of the surrounding communities. Crashes involving big rigs with toxic materials can result in devastating explosions.

Injury victims involved in preventable HAZMAT crashes should know they deserve compensation for their damages, including medical bills, lost wages, and pain and suffering. Let our injury attorneys hold the person or party responsible for your injuries accountable for their actions. 

If you or a loved one was injured or lost their life in a truck or 18-wheeler crash that was carrying hazardous materials, reach out to a Rancho Cordova truck accident lawyer to learn more about your rights.

Why Are HAZMAT Truck Crashes So Dangerous?

According to the National Safety Council (NSC), there were 392 truck accident deaths in California in 2023, making it the second deadliest state for that year. However, the U.S. Federal Motor Carrier Safety Administration (FMCSA) states that HAZMAT truck accidents, spills, injuries, and fatalities are low in comparison to the overall amount of hazardous material that is transported across United States highways.

Unfortunately, HAZMAT truck crashes are more likely to cause catastrophic injuries or wrongful death, inflict tremendous damage on the surrounding communities, and significantly impact the economy. 

The impact of a crash involving a truck hauling hazardous liquids could cause toxic materials to spill, creating dangerously slippery conditions along the highway, especially when the substance spilled is oil-based. 

A HAZMAT spill can create poor road conditions that can cause drivers to lose control of their vehicles, causing a multi-car accident. Victims of HAZMAT accidents, as with other big rig or 18-wheeler crashes, often suffer severe internal injuries, bone fractures, spinal cord damage, and traumatic brain injuries (TBI).

The presence of hazardous materials increases the risk of serious injuries and the potential for the following:

•         Poisoning from toxic gases 

• Chemical or thermal burns from fire/explosions/flames or chemicals
• Blindness or eye damage 
• Loss of hearing or amputations from explosions 
• Respiratory distress problems 
• Neurological damage
• Exposure to cancer-causing substances
• Slip and fall injuries caused by oily surfaces 

At Triumph Law, we have the resources to identify the cause of the accident, including the spill, and the parties who failed in their duty to transport the hazardous material safely. We are here to help you seek fair compensation and hold those accountable for your losses.

Hazardous Material Transportation

According to the U.S. Department of Transportation (USDOT), more than 50 percent of the 2.59 billion tons of hazardous materials were moved by trucks in 2022. These hazardous materials vary in form, function, and lethality and are divided into nine separate classes:

• Class 1-Explosives: Materials that can act as projectiles or trigger an explosion, detonating devices, or blasting agents
• Class 2-Gases: Non-flammable and flammable gases, such as toxic gases
•  Class 3-Flammable Liquids: Ethanol, kerosene, motor oil, diesel or jet fuel, gasoline, etc.
• Class 4-Flammable Solids and Spontaneously Combustible Materials: These can include magnesium, aluminum powder, activated charcoal, and sulfur.
• Class 5-Oxidizers and Organic Peroxides: These materials can increase the burning of other materials.
• Class 6-Toxic Materials and Infectious Substances: Infectious substances that could cause death or disability if an animal or human is exposed to them, such as rat poison and similar toxins that are neither a gas nor a liquid.
• Class 7-Radioactive Material: These materials can negatively affect the environment and the residents living nearby for years.
• Class 8-Corrosive Materials: Base substances or strong acids that can quickly corrode or burn.
• Class 9-Miscellaneous: Dry ice, lithium batteries, and other potentially dangerous materials not included in other categories.

Our team at Triumph Law understands the federal regulations and standards regarding the transportation of hazardous materials and personal injury law. We can determine the full extent of your damages, deal with the insurers, and fight for the compensation you and your family deserve.

Truck Accident Hazardous Spill FAQs

What are the frequently cited hazmat violations?

The FMCSA established regulations to govern the transportation of hazardous materials via commercial carriers since HAZMAT accidents can pose severe threats to public safety and health. For instance, big rig trucks hauling hazardous materials are required to display warning placards. Additionally, a truck hauling hazardous materials must inform certain authorities anytime it carries dangerous cargo.

A hazardous material endorsement must be carried by HAZMAT truckers, proving they have been properly trained in the transportation procedures of dangerous materials. HAZMAT trucks are prohibited from using certain roads and restricted from operating during certain times of the day. Unfortunately, not all drivers and trucking companies abide by these regulations. 

Of the 168,869 inspections made in 2025, the FMCSA found 7,394 HAZMAT violations that took the trucks out-of-service (OOS). This value does not reflect the thousands of other violations issued that same year. The most frequent inspection violations included:

• The package was not secured in the vehicle
• No copy of their USDOT Hazardous Materials Registration Number
• No or improper shipping papers
• Shipping paper accessibility
• Placard damaged, obscured, or deteriorated
• No placards or markings when required
• Prohibited placarding
• Accessibility/maintenance of Emergency Response Information 
• Transport or offer without Emergency Response Information

What should you do if an 18-wheeler or a semi-tractor-trailer hits your vehicle?

If you are physically able, you should document as much of the accident scene as possible with videos and photographs. Inspect and photograph your vehicle and the truck at the scene, as well as any visible injuries. Injuries are not always apparent immediately following an accident, especially injuries associated with carcinogenic or toxic exposure, which could take years to present.

Exchange insurance information with the truck driver and collect contact information of witnesses to the accident. When police arrive on the scene, answer their questions only with facts, but do not speculate on who was at fault. Do not speak with the truck driver’s insurance company or claims adjuster without your personal injury attorney. 

Get checked out by the EMTs who arrive on the scene and head to the emergency room if they deem it necessary. Receiving medical attention right away will help you to take all the necessary steps to protect your health. Getting proper care will increase your chances of recovering fully and can help prove your damages by having proper documentation.

Who is responsible for a hazardous material spill?

For a truck accident involving a hazardous material spill, responsibility usually falls on the party whose negligence caused the crash or allowed the dangerous cargo to leak. These cases are often more complex than ordinary truck accidents because liability may extend beyond the driver to multiple companies involved in loading, maintaining, or transporting the materials.

Possible responsible parties include:

• The truck driver, for reckless driving, fatigue, distraction, or violating safety rules
• The trucking company, for poor hiring, inadequate training, or pushing unsafe schedules
• The cargo loading company, for improperly securing or handling hazardous materials
• The maintenance provider, for failing to inspect or repair brakes, tires, valves, or containment systems
• The shipping or logistics company, for improper labeling, documentation, or failure to follow hazardous material transport laws
• Third-party contractors, involved in handling or transferring the materials

Determining fault often requires a detailed investigation into driver logs, black box data, maintenance records, inspection reports, and compliance with federal hazardous material regulations.

Since these crashes can cause serious burns, toxic exposure, and environmental harm, identifying every responsible party is critical to pursuing full compensation.
