What to Do After a Truck Accident in California

Knowing what to do after a truck accident in California can protect your health, preserve important evidence, and help identify every person or business that may be responsible. A collision involving a tractor-trailer, delivery truck, box truck, construction vehicle, commercial van, or other large vehicle can be more complicated than an ordinary passenger-car accident.

Commercial-vehicle cases may involve the driver, the driver’s employer, a trucking company, a delivery business, a vehicle owner, a trailer owner, a leasing company, a cargo-loading company, a maintenance provider, or several insurers. Important evidence may also be controlled by these businesses and lost under routine document-retention policies.

Your immediate priorities should be safety and appropriate medical care. After addressing urgent concerns, document the vehicles and scene, identify witnesses, obtain commercial-vehicle information, report the accident when required, notify the appropriate insurer, and take reasonable steps to preserve electronic and company records.

1. Stop and Remain at the Truck-Accident Scene

Do not leave the scene without fulfilling your legal obligations.

California law requires a driver involved in an accident resulting in injury or death to stop immediately and provide identifying information and reasonable assistance. California Vehicle Code sections 20001 and 20003 address duties following injury-producing collisions.

Leaving the scene may create serious criminal and civil consequences.

Remain nearby unless emergency personnel transport you for medical care. Cooperate with law enforcement, but do not guess about facts you cannot accurately recall.

2. Move Away From Immediate Danger

Truck accidents can create continuing hazards because of the vehicle’s size, cargo, fuel, debris, and the possibility of secondary collisions.

When possible:

Move to a safe location away from active traffic.
Turn on hazard lights.
Stay away from leaking fuel or hazardous materials.
Do not stand between damaged vehicles.
Avoid walking behind or beside an unstable trailer.
Follow instructions from police, firefighters, or emergency personnel.

Call 911 when anyone may be injured, traffic is obstructed, a vehicle is unstable, cargo has spilled, fuel is leaking, or the truck driver leaves the scene.

Do not attempt to move cargo, open a trailer, or inspect underneath a damaged commercial vehicle.

3. Check for Injuries and Obtain Medical Care

Large commercial vehicles can generate substantial force even when visible vehicle damage appears limited.

Seek appropriate evaluation for symptoms such as:

Headache or dizziness
Confusion or memory difficulty
Neck or back pain
Numbness or tingling
Chest or abdominal pain
Difficulty breathing
Weakness
Significant swelling
Limited movement
Persistent or increasing pain

Some injuries may not become fully apparent until hours or days after the collision. Do not assume you are uninjured merely because adrenaline temporarily masks pain.

Medical records can also help establish when symptoms began, what treatment was recommended, and how the injuries developed.

4. Call Law Enforcement

A police or California Highway Patrol investigation may be especially important after a commercial-truck collision.

An officer may document:

Vehicle positions
Driver statements
Witness information
Traffic violations
Commercial identifying information
Insurance details
Skid marks and debris
Cargo conditions
Possible impairment
Whether additional commercial enforcement is needed

Ask how to obtain the collision report and record the responding agency’s report number.

A police report can be useful evidence, but it does not necessarily make the final decision about civil responsibility. Other evidence may support a different or more complete explanation.

5. Obtain the Truck’s Identifying Information

Understanding what to do after a truck accident in California includes collecting information beyond the truck driver’s name and insurance card.

When it is safe, photograph or record:

The driver’s full name
Driver’s-license information
Commercial driver’s-license information
The truck’s license plate
The trailer’s license plate
The vehicle identification number
The company name displayed on the cab
The United States Department of Transportation number
Motor-carrier identifying numbers
Truck and trailer unit numbers
Insurance information
The vehicle owner’s name
The trailer owner’s name
Visible cargo markings
Hazardous-material placards
Delivery or company logos

The name displayed on the vehicle may not be the same as the driver’s employer, vehicle owner, carrier, or company responsible for the shipment. Photograph every available identifier.

6. Photograph the Entire Accident Scene

Evidence can disappear quickly when vehicles are moved, cargo is collected, debris is cleared, or the roadway reopens.

When safely possible, photograph:

The positions of all vehicles
Damage to every vehicle
The truck cab and trailer
License plates and company markings
Tire marks and debris
Damaged barriers or signs
Traffic signals
Lane markings
Road construction
Weather and lighting
Cargo on the roadway
Skid or gouge marks
Fluid leaks
Visible injuries
Nearby businesses and cameras

Take both close-up and wide-angle photographs. Wide views help establish lane positions, distances, and the surrounding roadway.

Do not enter an active traffic lane or approach unstable cargo merely to take pictures.

7. Identify Witnesses

Obtain the names and contact information of people who observed:

The truck before the collision
The impact itself
The truck driver’s conduct afterward
Statements by the truck driver
Cargo movement
Unsafe lane changes
Speeding or erratic driving
Traffic-signal conditions

Independent witnesses may be particularly important when the truck driver or trucking company disputes how the collision occurred.

Ask for:

Full name
Telephone number
Email address
A brief description of what the person saw

Do not assume law enforcement obtained every witness’s information.

8. Avoid Arguing or Admitting Fault

Remain calm and provide required information, but avoid arguing about responsibility.

Do not make statements such as:

“It was my fault.”
“I should have seen the truck.”
“I was in the truck’s blind spot.”
“I am not injured.”
“The accident was minor.”
“I am completely fine.”

A person may apologize out of courtesy or reach a conclusion before understanding the physical, video, and electronic evidence.

Answer law-enforcement questions truthfully, but do not speculate about speed, distance, timing, or events you did not observe.

9. Report the Accident to the California DMV When Required

California generally requires a driver to submit an SR-1 accident report to the DMV within 10 days when anyone was injured or killed or when property damage exceeded $1,000. The requirement applies even when an injury seems minor. A police report does not replace the driver’s SR-1 obligation.

The official California DMV accident-reporting page provides the SR-1 form and filing instructions.

The SR-1 is different from:

A police collision report
A California Highway Patrol report
A claim against an insurer
A lawsuit
A trucking-company incident report

Keep a copy of the completed form and proof of submission.

10. Notify Your Insurance Company

Review your automobile policy and provide timely notice of the collision.

Your insurer may request:

The date and location
The vehicles involved
Police-report information
Photographs
A description of damage
Information about injuries

Depending on the policy, coverage may include:

Collision coverage
Medical-payments coverage
Rental-car coverage
Uninsured-motorist coverage
Underinsured-motorist coverage

Report accurate facts, but do not speculate about responsibility or minimize injuries whose extent is not yet known.

11. Use Caution With the Trucking Company’s Insurer

A trucking company or commercial insurer may begin investigating immediately. An adjuster, investigator, or company representative may contact you before you understand the extent of your injuries.

They may request:

A recorded statement
A signed medical authorization
Access to prior medical records
Photographs of your vehicle
Inspection of electronic devices
A quick settlement
A release of all claims

A recorded statement can later be used to challenge your description of the accident or injuries. A broad medical authorization may permit access to unrelated records. An early settlement may fail to account for surgery, future treatment, lost earning capacity, or permanent limitations.

Do not sign a settlement release without understanding that it ordinarily ends the claim permanently.

12. Preserve the Vehicle and Physical Evidence

Do not immediately authorize destruction, salvage, or disposal of the damaged vehicle when a serious injury or disputed truck collision is involved.

The vehicle may contain evidence concerning:

Impact location
Crush patterns
Seat-belt use
Airbag deployment
Steering and braking
Event-data information
Occupant movement
Mechanical damage

Keep damaged personal property, including:

Child safety seats
Helmets
Eyeglasses
Clothing
Mobile devices
Cargo or work equipment
Other items damaged in the impact

Allow insurers to inspect the vehicle when appropriate, but preserve your ability to conduct an independent inspection when necessary.

13. Request Preservation of Trucking Records

Commercial evidence may be lost through automatic deletion, routine recycling, vehicle repair, or document-retention policies.

A written preservation request may identify materials such as:

Electronic logging-device data
GPS and route history
Dash-camera footage
Cab-camera footage
Dispatch communications
Text messages
Delivery instructions
Driver qualification records
Training records
Inspection reports
Maintenance records
Cargo documents
Weight tickets
Bills of lading
Employment agreements
Contractor agreements
Insurance policies
Drug and alcohol testing records
Prior safety complaints

The Federal Motor Carrier Safety Administration’s ELD guidance explains that an electronic logging device synchronizes with a commercial vehicle’s engine and automatically records driving time.

FMCSA guidance states that motor carriers generally retain ELD records of duty status and supporting documents for six months. That retention rule does not mean an injured person should wait six months to act. Prompt preservation is still important.

Read our guide to evidence to preserve after a truck accident.

14. Determine Whether Driver Fatigue May Have Contributed

Federal hours-of-service regulations limit the driving and on-duty time of many commercial drivers.

For example, FMCSA’s current summary states that a property-carrying driver generally may drive up to 11 hours after 10 consecutive hours off duty, subject to additional rules and exceptions.

Possible fatigue evidence may include:

Electronic logs
Paper logs
Fuel receipts
Toll records
Delivery timestamps
Dispatch messages
GPS history
Hotel receipts
Vehicle movement data
Phone records

Not every commercial driver is subject to the same rules, and exemptions may apply. The driver’s work, vehicle, cargo, route, and operating status must be evaluated.

15. Identify Every Potentially Responsible Party

Truck-accident responsibility may extend beyond the driver.

Potential parties may include:

The truck driver
The driver’s employer
A motor carrier
A delivery company
The vehicle owner
The trailer owner
A leasing company
A contractor
A freight broker
A logistics company
A cargo-loading company
A maintenance provider
A repair facility
A tire manufacturer
A vehicle or component manufacturer
A government entity

A company may be responsible for the driver’s conduct or for its own negligence, including:

Negligent hiring
Inadequate training
Unsafe scheduling
Poor supervision
Failure to inspect the vehicle
Inadequate maintenance
Allowing an unqualified driver to operate
Improper cargo loading
Ignoring previous safety concerns

Calling a driver an independent contractor does not automatically determine responsibility. The actual relationship, degree of control, contracts, vehicle ownership, and insurance arrangements must be reviewed.

16. Review All Available Insurance

A commercial-truck collision may involve several insurance policies.

Potential coverage may include:

The motor carrier’s liability policy
The driver’s policy
The vehicle owner’s policy
The trailer owner’s coverage
A delivery company’s policy
Employer liability coverage
Excess or umbrella insurance
Cargo-related coverage
Uninsured- or underinsured-motorist coverage
Medical-payments coverage

Insurance identification can be especially complicated when the vehicle was leased, rented, operated by a contractor, or used for an app-based delivery service.

17. Document Medical Treatment and Financial Losses

Keep organized records of:

Emergency treatment
Hospital care
Diagnostic tests
Surgery
Physical therapy
Prescriptions
Medical bills
Mileage to appointments
Missed work
Lost income
Business losses
Household assistance
Mobility equipment
Other accident-related expenses

Also keep a reasonable daily record of:

Pain
Sleep disruption
Mobility restrictions
Activities you cannot perform
Work limitations
Assistance needed at home
Changes in family or recreational activities

Do not exaggerate. Accurate, contemporaneous documentation can help explain the effect of the injuries between medical appointments.

18. Avoid Posting About the Collision Online

Insurance companies may review publicly available social-media activity.

Avoid posting:

Accident photographs
Statements about fault
Medical updates
Settlement discussions
Comments about the truck driver
Videos of physical activities
Travel or recreational photographs without context

Even an innocent photograph may be presented in a misleading way.

Do not delete existing material after a claim has arisen without obtaining appropriate advice because deletion may create a separate evidence issue.

19. Understand California Comparative Negligence

A trucking insurer may argue that the injured person contributed to the accident by:

Remaining in the truck’s blind spot
Passing on the right
Following too closely
Speeding
Changing lanes unsafely
Failing to yield
Driving while distracted
Failing to avoid the collision

California comparative-negligence principles may permit recovery even when an injured person shares some responsibility. Compensation may be reduced according to the percentage of fault assigned.

Learn more in our guide to California comparative negligence.

20. Do Not Miss California Filing Deadlines

California Code of Civil Procedure section 335.1 generally provides a two-year limitations period for many personal-injury lawsuits.

Different deadlines and exceptions may apply depending on the parties, the injured person’s circumstances, and the type of claim.

A shorter claim process may apply when a public entity is involved. Examples may include:

A city or county truck
A public bus
A public-works vehicle
A government employee
A government contractor
A dangerous roadway condition
Defective traffic controls
Public construction or maintenance

California Government Code section 911.2 generally requires a personal-injury claim against a public entity to be presented within six months after the claim accrues.

Presenting a government claim is different from filing a lawsuit. Additional deadlines may apply after the entity accepts, rejects, or fails to act on the claim.

Evidence can disappear long before either deadline expires.

Common Mistakes After a California Truck Accident

Common mistakes include:

Failing to photograph commercial identifiers
Relying only on the driver’s insurance card
Allowing the damaged vehicle to be destroyed
Losing dash-camera footage
Waiting to request trucking records
Failing to identify witnesses
Missing the DMV SR-1 deadline
Giving a premature recorded statement
Signing a broad medical authorization
Accepting a settlement before treatment is complete
Assuming the police report identifies every responsible party
Believing an independent-contractor label ends the investigation
Posting about the accident online
Waiting until the filing deadline approaches

Commercial evidence often exists for only a limited time. Early investigation may determine what can still be recovered.

Compensation After a California Truck Accident

Depending on the injuries and evidence, compensation may include:

Emergency medical care
Hospitalization
Surgery
Diagnostic testing
Rehabilitation
Future medical treatment
Lost wages
Lost business income
Reduced earning capacity
Pain and suffering
Emotional distress
Permanent impairment
Loss of enjoyment of life
Property damage
Towing and rental expenses
Home-care assistance
Accessibility modifications
Wrongful-death damages when applicable

The value of a claim depends on the injuries, responsible parties, insurance coverage, available evidence, comparative-fault arguments, future needs, and litigation risks.

No attorney should promise a particular result before evaluating the facts.

What to Do After a Truck Accident in California: FAQs

What information should I photograph on a commercial truck?

Photograph the company name, Department of Transportation number, truck and trailer unit numbers, license plates, insurance information, vehicle owner, cargo markings, and any hazardous-material placards.

Do I need to submit an SR-1 after a truck accident?

The California DMV generally requires an SR-1 within 10 days if anyone was injured or killed or property damage exceeded $1,000. A police report does not replace the SR-1.

Should I speak with the trucking company’s insurer?

You should provide truthful required information, but use caution before giving a recorded statement, signing a medical authorization, or accepting a settlement. Commercial insurers may investigate immediately after a crash.

What records should the trucking company preserve?

Depending on the case, relevant records may include electronic logs, GPS data, dash-camera footage, dispatch communications, delivery records, driver files, inspections, maintenance documents, cargo records, and insurance policies.

Are electronic driver logs always available?

No. Electronic logging requirements apply to many but not all commercial drivers, and exemptions exist. Other evidence such as GPS, toll, fuel, dispatch, delivery, and vehicle data may still be available.

What if the truck driver was an independent contractor?

The contractual label does not automatically determine liability. The relationship among the driver, motor carrier, delivery company, vehicle owner, and other businesses must be investigated.

Can I recover if I was partly responsible?

Potentially. California comparative-negligence principles may allow recovery even when an injured person shares some fault, although compensation may be reduced.

How long do I have to bring a truck-accident claim?

California generally provides two years for many personal-injury lawsuits. Claims involving public entities may require formal presentation within six months, and other deadlines or exceptions may apply.
