Truck Accidents
After a truck accident, get medical care first, report the crash to police, and photograph the vehicles, road, and your injuries before evidence disappears. Truck claims usually involve the driver, a trucking company, and commercial insurers, so deadlines and fault rules get complicated fast. This guide walks through each step, covers jackknife and 18 wheeler accident claims, and explains when people typically contact a semi truck accident lawyer.

Key facts
- 5,969 people killed in US crashes involving large trucks in 2022 (NHTSA revised count) (NHTSA, 2022)
- 70% of people killed in large-truck crashes were occupants of other vehicles (2022) (NHTSA, 2022)
- 5,472 people killed in US crashes involving large trucks in 2023, an 8% decrease from 2022 (NHTSA, 2023)
- 153,452 people estimated injured in US crashes involving large trucks in 2023 (NHTSA, 2023)
Driver Fatigue
Federal Hours of Service regulations limit driving time, but violations are common. Drowsy truck drivers have significantly impaired reaction times.
Distracted Driving
Cell phone use, dispatching devices, and other distractions are particularly dangerous at commercial vehicle speeds and weights.
Improper Loading
Overloaded or improperly secured cargo can cause trucks to tip, jackknife, or shed debris onto the roadway.
Brake Failure
Commercial trucks require significantly more stopping distance. Brake maintenance failures are a leading mechanical cause of accidents.
Speeding and Aggressive Driving
Delivery and schedule pressure can push drivers to speed or drive aggressively, especially on highways.
Inadequate Training
Improperly trained drivers may be unprepared for adverse weather, emergency maneuvers, or hazardous cargo handling.
DUI / Impairment
Commercial drivers are held to a lower legal BAC limit (0.04%) than non-commercial drivers, but violations still occur.
These types of accidents are frequently associated with the following injuries. Select an injury to learn more.
- 1
Call 911 immediately
CriticalTruck accidents frequently involve serious injuries. Call 911 even if you believe injuries are minor - symptoms can be delayed.
- 2
Do not move injured parties
CriticalSpinal injuries are common in truck accidents. Avoid moving anyone unless they are in immediate danger.
- 3
Photograph everything before vehicles are moved
CriticalTrucks are often moved quickly for traffic management. Document skid marks, final vehicle positions, road conditions, and all damage before anything is cleared.
- 4
Get the truck's DOT number and carrier information
ImportantLocated on the truck's door or cab. This identifies the carrier and is essential for investigating insurance and regulatory compliance.
- 5
Request the driver's log book information
ImportantFederal law requires commercial drivers to keep Hours of Service logs. This is critical evidence that can disappear quickly.
- 6
Identify any witnesses
ImportantOther drivers, passengers, or bystanders who saw the accident. Independent witness accounts are especially important when dealing with large carriers.
- 7
Seek immediate medical evaluation
CriticalTruck accident injuries are often severe. Even if you feel functional, internal injuries and traumatic brain injuries may not be immediately apparent.

Statute of limitations for personal injury
Arizona also has a 2-year statute of limitations for personal injury claims. Consult an attorney early to protect your options.
Multiple liable parties
Truck accidents may involve the driver, the trucking company, the cargo loader, a maintenance contractor, or the truck manufacturer. Identifying all responsible parties is complex and consequential.
Higher insurance minimums
Commercial trucks are required to carry significantly higher liability insurance than passenger vehicles - often $750,000 to $5 million. This also means carriers have experienced claims teams.
Aggressive carrier defense
Large trucking companies often have dedicated legal and claims teams. They may contact you quickly after an accident with settlement offers. Early offers are typically below the full value of damages.
Independent contractor complications
Some truck drivers operate as independent contractors rather than employees, which can affect which insurance policies apply and who bears liability.
Federal regulations exposure
FMCSA violations (hours of service, drug testing, maintenance requirements) can establish negligence. These records must be requested before they are destroyed.

Frequently asked questions
Check for injuries and call 911, then move to safety if you can. Get the truck driver's license, the carrier name on the cab, and the DOT number, and photograph everything before vehicles are moved. Prompt medical care also creates the records an insurance claim relies on.
Depending on the facts, liability after a commercial truck accident can involve the driver, the trucking company, a cargo loader, or a maintenance contractor. That is one reason truck claims are usually more complex than car claims.
Not every claim needs one, but you may benefit from speaking with a lawyer experienced in commercial vehicle cases when injuries are serious, fault is disputed, or a trucking company's insurer contacts you quickly. Many offer free consultations.
Both California and Arizona generally allow 2 years from the accident date to file a personal injury lawsuit, and claims against government entities may have shorter deadlines. Truck evidence like electronic logging data can be overwritten within days, so acting early matters. Consult a licensed attorney for deadlines specific to your situation.
There is no single rule, but people often speak with a lawyer experienced in commercial trucking cases when injuries required hospitalization or ongoing treatment, multiple parties could be liable (the driver, the carrier, a cargo loader, or a maintenance contractor), or the driver may have violated federal regulations like Hours of Service limits. A lawyer can also send a spoliation or evidence-preservation letter to the carrier so electronic logging device data and other digital records are not overwritten before they are reviewed. This is educational information, not legal advice, and every situation is different.
A jackknife accident happens when a truck's trailer swings out and folds against the cab, often at a sharp angle, usually triggered by hard braking, slippery roads, worn brakes, or improperly loaded or secured cargo. Because a jackknifing trailer can block multiple lanes, these crashes often involve several vehicles and cause serious injuries. Photos of the truck's final position and any skid marks can help show what happened.
An 18 wheeler accident claim follows the same process as other truck accident claims: documenting the scene, identifying the carrier using the USDOT number on the truck and the driver from the police report, and preserving time-sensitive evidence such as electronic logging device data and the driver's hours of service records before a carrier's investigation team can respond. Because 18 wheelers are large commercial vehicles, more than one party, such as the driver, the carrier, or a cargo loader, may share responsibility. Consult a licensed attorney for guidance specific to your claim.
