What to Do After a Semi-Truck Accident in Pasadena, CA
A collision with a semi-truck or other large commercial vehicle can be a frightening and overwhelming experience. Because commercial trucks are significantly larger and heavier than passenger vehicles, these accidents can result in serious injuries, extensive property damage, and complicated insurance claims.
If you've been involved in a truck accident in Pasadena, California, knowing what steps to take afterward can help protect your health, preserve important evidence, and safeguard your legal rights.
Unlike a typical car accident, a commercial truck collision may involve multiple responsible parties, including the truck driver, trucking company, maintenance provider, or another business. The evidence needed to establish liability may also be more complicated.
At Rodriguez Law Group, Inc., we help individuals and families throughout Pasadena and Southern California understand their legal options following serious truck accidents.
Here are the important steps to take after a semi-truck accident and the mistakes to avoid when pursuing a potential injury claim.
1. Check for Injuries and Call 911
Your safety and the safety of everyone involved should be your first priority.
If you are involved in a collision with a commercial truck, stop at the scene and assess whether anyone needs emergency medical assistance.
Call 911 immediately if someone is injured or there is an immediate danger.
If your vehicle is creating a traffic hazard and it is safe and appropriate to move it, follow the directions of emergency responders or law enforcement. Avoid moving anyone who may have suffered a serious neck, back, or spinal injury unless necessary to prevent immediate harm.
Semi-truck accidents can cause severe injuries, including:
Spinal cord injuries
Broken bones and fractures
Internal bleeding
Neck and back injuries
Crush injuries
Burns and lacerations
Some injuries may not be immediately noticeable because of shock or adrenaline.
Even if you believe your injuries are minor, obtaining a medical evaluation as soon as possible is important.
2. Report the Truck Accident to Law Enforcement
Reporting a commercial truck accident helps establish an official record of the collision.
In Pasadena, the appropriate responding agency may depend on where the accident occurred. Collisions on local streets may involve the Pasadena Police Department, while highway accidents may be handled by the California Highway Patrol.
When officers respond, provide accurate information about what happened.
Avoid guessing about details you do not remember or making assumptions about who caused the collision.
The accident report may contain important information, including:
The date, time, and location of the collision
Names and contact information of involved drivers
Vehicle descriptions
Insurance information
Witness information
Road and weather conditions
Statements from involved parties
The responding officer's observations
Ask how to obtain a copy of the accident report for your records.
California reporting requirements: If a collision causes injury or death, California generally requires a report to law enforcement within 24 hours. A separate DMV SR-1 report is required within 10 days when someone is injured or killed, or property damage exceeds $1,000. This DMV requirement applies regardless of fault and is separate from any police or insurance report.
3. Document the Accident Scene
If you are physically able to do so safely, collect as much information as possible before leaving the accident scene.
Photographs, videos, and witness information can help establish what happened and preserve details that may change or disappear after the collision.
Consider documenting:
Damage to your vehicle
Damage to the commercial truck
Vehicle positions following the collision
Skid marks and roadway debris
Traffic signals and road signs
Weather and visibility conditions
Nearby construction zones
Visible injuries
Commercial vehicle identification numbers
The trucking company's name or logo
If the accident occurred on Interstate 210, State Route 134, or another heavily traveled Pasadena roadway, prioritize your safety and follow emergency personnel's instructions rather than attempting to collect evidence in dangerous traffic conditions.
Why Photographs Matter in Truck Accident Cases
Commercial trucks may be moved or repaired after a collision, and roadway evidence can disappear quickly.
Photographs taken shortly after the accident may help accident reconstruction professionals evaluate vehicle damage, impact locations, and other relevant details.
Even photographs taken by passengers or witnesses may become important evidence later.
4. Gather Information About the Truck Driver and Trucking Company
One important difference between a truck accident and a typical car accident is that the driver may not own the vehicle or work directly for the company identified on the truck.
If it is safe and practical, collect:
The truck driver's name and contact information
Driver's license information
The trucking company's name
The truck's license plate number
The tractor and trailer identification numbers
Available insurance information
The commercial vehicle's USDOT number, if displayed
Contact information for witnesses
The trucking company's identity can be particularly important because commercial truck accidents may involve employers, motor carriers, independent contractors, and other businesses.
Do not assume the truck driver is the only person who may be legally responsible.
5. Seek Medical Attention and Follow Your Treatment Plan
Some injuries resulting from truck accidents may develop or become more noticeable in the hours or days following a collision.
For example, a person with a concussion may initially experience only a headache or dizziness before developing additional symptoms.
Other injuries, including certain neck, back, and soft tissue injuries, may also become more apparent over time.
A medical evaluation can help identify injuries and establish documentation connecting your symptoms to the accident.
After receiving medical attention:
Follow your healthcare provider's treatment recommendations
Attend follow-up appointments
Keep copies of medical records
Save receipts for medications and treatment expenses
Document symptoms and physical limitations
Maintain records of missed work
If you develop new or worsening symptoms, seek appropriate medical care.
Medical documentation can become important evidence when evaluating a personal injury claim.
6. Preserve Evidence Unique to Commercial Truck Accidents
Commercial trucks often contain records and electronic systems that may provide valuable information about the circumstances surrounding a collision.
Depending on the vehicle and motor carrier, potentially relevant evidence may include:
Electronic Logging Device Records
Many commercial trucks use electronic logging devices to record driver hours of service.
These records may help determine whether a driver complied with applicable driving and rest requirements.
Vehicle Event Data
Certain commercial vehicles contain onboard systems that record information about vehicle operation.
Depending on the system, available data may help investigators evaluate speed, braking, and other circumstances surrounding the accident.
Driver Qualification Records
Commercial motor carriers may maintain records concerning driver licensing, training, qualifications, and employment history.
These records can become relevant when evaluating allegations involving negligent hiring or inadequate training.
Maintenance and Inspection Records
Truck maintenance records may reveal previous mechanical problems, inspection findings, or repair histories.
These documents can be important when brake failures, tire problems, or other equipment issues may have contributed to a collision.
Dispatch and Delivery Records
Dispatch communications, transportation schedules, and delivery records may help establish the driver's work assignments and activities before the accident.
Why Acting Quickly Matters
Some electronic and business records are retained only for limited periods, while certain vehicle data may be overwritten or become unavailable.
An attorney can evaluate whether appropriate evidence preservation requests or other legal measures are necessary.
Preserving trucking records early may help prevent important evidence from being lost before a claim is fully investigated.
7. Notify Your Insurance Company, but Be Careful With Statements
After a truck accident, notify your insurance company as required by your policy.
Provide accurate information about the collision and cooperate with reasonable requests under your coverage agreement.
However, be cautious when communicating with the trucking company's insurance representative.
Commercial truck accidents may involve substantial insurance coverage and multiple insurers.
An adjuster may request a recorded statement, medical authorization, or other documentation shortly after the accident.
Before agreeing to broad requests or accepting a settlement, consider whether you understand the full extent of your injuries and financial losses.
Should You Accept an Early Settlement Offer?
An early settlement offer may seem appealing, especially when medical expenses and lost wages are creating financial pressure.
However, some serious injuries require ongoing treatment, rehabilitation, or future medical care.
Accepting a settlement and signing a release may prevent you from seeking additional compensation for the same claim later.
Before accepting an offer, consider speaking with a Pasadena truck accident attorney about your legal options.
8. Understand Who May Be Responsible for the Truck Accident
Determining liability after a semi-truck accident can be more complicated than determining fault in an ordinary passenger vehicle collision.
Depending on the circumstances, potentially responsible parties may include:
The Truck Driver: A driver may be liable when distracted driving, speeding, fatigue, impairment, or another negligent action contributes to the collision.
The Trucking Company: A trucking company may face liability for certain negligent actions of its employees or for its own negligent hiring, supervision, or maintenance practices.
Maintenance Providers: A repair or maintenance contractor may be responsible when negligent work contributes to mechanical failure.
Cargo Loading Companies: Improperly loaded or secured cargo can contribute to rollover accidents, loss of vehicle control, or falling cargo.
Truck Manufacturers: A manufacturer or another responsible party may face liability if a defective vehicle component contributed to the accident.
More than one party may share responsibility.

9. Keep Track of Your Expenses and Financial Losses
Truck accidents can create significant financial challenges for injured individuals and their families.
Keeping detailed records can help document the financial impact of your injuries.
Important records may include:
Medical bills and treatment receipts
Prescription medication expenses
Rehabilitation and therapy costs
Transportation expenses related to medical care
Vehicle repair or replacement estimates
Pay stubs documenting lost wages
Employment records showing missed work
Receipts for necessary medical equipment
Documentation of ongoing care needs
In more serious cases, injuries may affect a person's future earning capacity or ability to perform everyday activities.
Maintaining organized records can help establish the extent of your losses.

Depending on the circumstances, compensation may include:
Medical Expenses
Emergency treatment, hospitalization, surgery, rehabilitation, medication, and reasonably supported future medical care.
Lost Income
Wages lost during recovery and potential reductions in future earning capacity.
Pain and Suffering
Physical pain, emotional distress, and other non-economic losses associated with the injuries.

How Long Do You Have to File a Truck Accident Claim in California?
In many California personal injury cases, the statute of limitations is generally two years from the date of injury.
However, exceptions and different deadlines may apply.
For example, if a government entity is potentially responsible, an administrative claim may need to be presented within six months in certain personal injury cases.
Missing an applicable deadline may affect your ability to pursue compensation.
Because truck accident cases may involve multiple defendants and different legal requirements, consulting an attorney promptly can help clarify the deadlines that apply to your situation.
Common Mistakes to Avoid After a Truck Accident
Following a commercial truck collision, certain mistakes can make it more difficult to document your injuries or pursue a potential claim.
Common mistakes include:
Delaying necessary medical treatment
Failing to report the accident when required
Forgetting to document the trucking company's information
Losing photographs, medical records, or receipts
Posting detailed statements about the accident on social media
Speculating about fault or the extent of your injuries
Signing an insurance release without understanding its terms
Accepting a settlement before evaluating future expenses
Waiting too long to investigate the collision
Every accident is different, but taking reasonable steps to preserve evidence and obtain appropriate medical care can help protect your interests.
Frequently Asked Questions About Semi-Truck Accidents in Pasadena
What should I do immediately after a semi-truck accident?
Stop safely, check for injuries, and call 911 if anyone needs emergency assistance. Report the collision, exchange information, and document the scene if you can do so safely. Seek medical attention and preserve any available evidence.
Do I need to file a police report after a truck accident in California?
California requires reporting to law enforcement within 24 hours when a collision causes injury or death. In addition, an SR-1 report must generally be submitted to the DMV within 10 days if someone was injured or killed, or property damage exceeded $1,000.
What if the trucking company contacts me after the accident?
You may receive calls from the trucking company or its insurer. Be accurate in your communications, but use caution before providing recorded statements, signing broad medical authorizations, or accepting settlement offers.
An attorney can help you understand your rights and obligations.
Can I sue both the truck driver and the trucking company?
Potentially, yes. Depending on the circumstances, both the driver and the trucking company may face liability.
A trucking company may be responsible for certain employee actions or its own negligent conduct.
What if I was partially responsible for the truck accident?
California generally follows a pure comparative negligence system.
This means you may still be able to recover compensation even if you were partially responsible, although your recovery is generally reduced according to your percentage of fault.
What if my injuries did not appear until days after the accident?
Some injuries may not become noticeable immediately.
Delayed symptoms do not automatically prevent someone from pursuing a personal injury claim. However, prompt medical evaluation and appropriate documentation can be important.
How long does a truck accident case take to settle?
The timeline depends on factors such as the severity of the injuries, the length of medical treatment, the complexity of the investigation, insurance negotiations, and whether litigation is necessary.
Some cases resolve through negotiations, while others require additional time.
