Commercial Trucking and Federal Safety Rules

California Truck Accident Lawyer

A commercial truck runs on paperwork: driver logs, brake records, inspection reports, the file on who hired the driver. After a crash, that paperwork often explains what went wrong. The Law Offices of Burg & Brock represent people hurt in truck collisions across California, and the first job is requesting those records before the carrier may lawfully discard them.

The Short Answer

Do I Have a Truck Accident Claim in California?

Possibly. If the truck driver, the motor carrier, a loader, a repair shop or another party broke a safety rule or failed to use reasonable care, and that contributed to your injuries, California law lets you bring a claim. The lawsuit deadline is generally two years. Some of the carrier’s own records can be discarded after six months, so the evidence clock runs faster.

That last point is the one people miss. Federal rules say how long a carrier must keep hours records, maintenance files and inspection reports, and several of those periods are measured in months. A claim can still be timely long after the most useful records were lawfully shredded.

So a truck case turns on documents: who was driving, for how long, in what vehicle, maintained by whom, carrying what, and under whose authority. The sections below take each in turn.

The Difference

Why a Truck Crash Is Not a Big Car Crash

The physics are worse. The bigger difference is that trucking is regulated, and regulation leaves a trail.

  • 01Weight and stopping distance

    A loaded tractor-trailer weighs many times what a car does and needs far more road to stop. Injuries tend to be serious.

  • 02A rulebook for almost everything

    Federal and state rules cover driver hiring, hours at the wheel, maintenance and how cargo is tied down.

  • 03More than one possible defendant

    Driver, carrier, trailer owner, loader, repair shop. Each can carry a share of the fault.

  • 04Records with an expiry date

    The rules say how long carriers must keep records. After that, disposal is lawful unless someone has asked for preservation.

  • 05Layered insurance

    Primary, excess and trailer policies can all sit behind one truck.

  • 06The carrier moves quickly

    Carriers and insurers often start investigating within hours. You should not wait months either.

  • Why this page is built around records

    Most of what decides a truck case is not in the police report. It sits in the carrier’s files and the truck’s electronics, which is where our investigation starts. For the everyday causes behind these crashes, see our guide to the causes of truck accidents.

    Federal and California Law

    Which Safety Rules Apply to a Commercial Truck?

    Usually both sets. Which rule governs a given question depends on the truck, the load and whether the trip crossed a state line.

    Federal rules

    49 CFR Parts 390 to 399

    The Federal Motor Carrier Safety Regulations govern commercial motor vehicles in interstate commerce. Under 49 CFR 390.5, that includes vehicles rated at 10,001 pounds or more, well below tractor-trailer size.

    • Part 391: driver qualification
    • Part 392: driving rules, including fatigue, texting and hand-held phones
    • Part 393: equipment and cargo securement
    • Part 395: hours of service
    • Part 396: inspection, repair and maintenance

    California rules

    Vehicle Code and Title 13

    Vehicle Code section 34500 directs the CHP to regulate the safe operation of trucks with three or more axles over 10,000 pounds and all truck tractors, among others. Section 34620 requires a motor carrier of property to hold a state Motor Carrier Permit.

    • Title 13, section 1212.5: hours for drivers who stay in California
    • Vehicle Code 34505.5: inspections at least every 90 days
    • Vehicle Code 22406: a 55 mph limit for three-axle trucks and anything towing
    • Vehicle Code 21655: right-hand or designated lanes for those trucks

    A broken safety rule is strong evidence. It is not the whole case.

    Under Evidence Code section 669, violating a statute or regulation can create a presumption of negligence, but only if the violation caused the injury and the rule was meant to prevent that kind of harm. The presumption can be rebutted.

    A log violation from three weeks before the crash proves little on its own. A driver past the legal limit at the moment of impact is exactly what the hours rules were written to prevent. The connection is what matters. Our longer guide on truck accident negligence covers how that connection gets proved.

    Federal text from the Electronic Code of Federal Regulations. California text from California Legislative Information.

    Hours of Service

    How Long Can a Truck Driver Legally Drive?

    Fatigue is the reason these limits exist. The numbers differ depending on whether the driver was running interstate or only inside California.

    Interstate property carriers

    49 CFR 395.3

    • 10 consecutive hours off duty before a shift
    • No more than 11 hours of driving
    • No driving after the 14th hour since coming on duty
    • A 30-minute break after 8 hours of driving
    • No driving after 60 hours on duty in 7 days, or 70 in 8 days
    • A 34-hour off-duty period can restart the weekly count

    California intrastate truck drivers

    13 CCR 1212.5

    • 10 consecutive hours off duty before a shift
    • No more than 12 hours of driving
    • No driving after the end of the 16th hour on duty
    • No driving after 80 hours on duty in 8 consecutive days
    • A 34-hour off-duty period can restart the eight-day count
    • Tank vehicles over 500 gallons carrying flammable liquid: 10 hours of driving

    Separately, 49 CFR 392.3 bars a carrier from requiring or allowing someone to drive while fatigue or illness makes it unsafe, whatever the log says. A driver can be inside the hour limits and still too tired to drive.

    Most interstate trucks record duty status on an electronic logging device. The useful test is whether the log agrees with fuel receipts, toll records, dispatch messages and delivery times.

    What gets compared against the log

    ELD recordsFuel receiptsToll dataDispatch messagesBills of ladingDelivery timesGPS dataPhone records

    Sources: 49 CFR 395.3, 49 CFR 395.8 and 13 CCR 1212.5. Exceptions exist, including short-haul exemptions under 49 CFR 395.1 and several categories in Title 13, section 1212. Which rule applied to a given driver is one of the first questions we check.

    Maintenance and Inspection

    What If Brakes, Tires or Lights Failed?

    Every motor carrier has to inspect, repair and maintain the vehicles it controls, systematically. That duty produces a paper file.

    Under 49 CFR 396.3, a carrier must keep parts and accessories in safe operating condition at all times, including brakes, steering, suspension, wheels and tires. It has to keep records of inspections, repairs and maintenance for each vehicle. Drivers file inspection reports under 396.11, and each vehicle needs a documented periodic inspection under 396.17.

    California adds its own rule. Vehicle Code section 34505.5 requires carriers running heavier trucks and truck tractors to inspect each one at least every 90 days, covering brakes, steering, suspension, tires, wheels and coupling devices, and to keep those records for two years.

    When a brake or tire failure is part of the story, these files are where it starts. Did the last inspection flag the problem, and who did the repair? Sometimes the answer points at an outside maintenance shop or a component manufacturer rather than the carrier. When it does, that side of the case connects to our product liability practice.

    Inspected on the truck itself

    Brake adjustmentAir lines and leaksTires and wheelsSteeringSuspensionLights and reflectorsCoupling devicesUnderride guard
    The truck may not stay put

    A damaged tractor can be repaired and back in service, or sold, within weeks. If its condition matters, the request to hold it for inspection has to go out early.

    Cargo

    What If the Load Shifted or Fell From the Truck?

    Federal rules say cargo must be secured so it cannot leak, spill, blow or fall off, and cannot shift enough to affect how the truck handles.

  • 01Falling or spilled cargo

    Loose material, a dropped load or debris in the lane. 49 CFR 393.100 is the starting point.

  • 02Shifting loads

    A load that moves in a turn or on a grade can push a trailer over or into another lane.

  • 03Overweight or unbalanced trailers

    Weight changes stopping distance and handling. Scale tickets and bills of lading show what was on board.

  • 04Who loaded it

    The shipper or a warehouse may have loaded and sealed the trailer. That can bring another party into the claim.

  • Tiedowns have their own specifications

    Part 393 sets performance criteria for securement systems. When a load comes loose, the questions are practical: how many tiedowns, rated for what, checked when. Our guide to the evidence in a loose cargo truck accident claim goes through it item by item.

    The Records Clock

    How Long Does a Trucking Company Keep Its Records?

    These are the minimum retention periods the regulations set. Once they pass, a carrier can lawfully discard the records unless it has been asked to preserve them.

    Hours logs: 6 monthsRecords of duty status and supporting documents. 49 CFR 395.8(k).
    Driver inspection reports: 3 monthsDriver vehicle inspection reports and repair certifications. 49 CFR 396.11.
    Maintenance records: 1 yearAnd 6 months after the vehicle leaves the carrier’s control. 49 CFR 396.3(c).
    Annual inspection: 14 monthsThe periodic inspection report. 49 CFR 396.21.
    California 90-day inspections: 2 yearsKept at the carrier’s terminal. Vehicle Code 34505.5(c).
    Driver file: employment + 3 yearsThe driver qualification file. 49 CFR 391.51.
    Accident register: 3 yearsA list of reportable crashes with copies of reports. 49 CFR 390.15(b).
    Drug and alcohol tests: 1 to 5 yearsNegative results 1 year; positive results and refusals 5 years. 49 CFR 382.401.

    Retention periods from the Federal Motor Carrier Safety Regulations (eCFR, current as of September 2026) and the California Vehicle Code.

    Compare those numbers with the two-year lawsuit deadline in Code of Civil Procedure section 335.1. The hours logs, which often matter most in a fatigue case, have the shortest life of all. Wait a year and the case can be intact while the logs are gone.

    Some of the most useful evidence is not on the list at all. Forward-camera footage, engine module data and fleet messaging have no retention period in these rules, and many systems overwrite old data automatically.

    What a preservation letter does

    It tells the carrier, and anyone else holding evidence, that a claim is coming and that specific records, data and the vehicle itself must be kept. Once a party is on notice, destroying that evidence can lead to penalties in the lawsuit. It works only if it arrives before the records are gone.

    Post-crash drug and alcohol testing

    Under 49 CFR 382.303, a carrier must test its surviving driver after a fatal crash, and after a crash where the driver is cited and someone was treated away from the scene or a vehicle was towed. Alcohol tests should happen within two hours; after eight hours the carrier stops trying and must write down why. For drugs the cut-off is 32 hours. Whether the required tests happened, and when, is itself evidence.

    Liability

    Who Can Be Responsible for a Truck Accident?

    Often more than one party. Working out which ones, and on what legal theory, is most of the early work.

    01The Truck Driver

    Speed, following distance, lane changes, phone use, fatigue or impairment.

    02The Motor Carrier

    For an employee driver on the job, and for its own hiring and supervision.

    03Tractor or Trailer Owner

    Where a separate company owns or leases the equipment.

    04Shipper or Loader

    Where the way the trailer was loaded or sealed contributed to the crash.

    05Maintenance Provider

    An outside shop that serviced brakes, tires or other parts.

    06Parts Manufacturer

    Where a defective component, not upkeep, caused the failure.

    07Freight Broker

    A contested area of law. Whether a claim against a broker is available depends on the facts and on current federal law.

    08Public Entity

    Where a dangerous road condition or work zone played a part. A six-month claim deadline applies.

    “The driver is an independent contractor”

    A label in a contract is not the end of it. California’s jury instruction on disputed employee status, CACI No. 3704, makes the most important factor whether the company had the right to control how the work was done. Our article on whether the company or the driver is liable covers how that plays out.

    Why every party matters

    Under Civil Code section 1431.2, each defendant’s liability for non-economic damages, such as pain and emotional distress, is several only, in proportion to its share of fault. Leave a responsible party out, and its share may go unpaid. Our overview of who is liable in a truck accident has more.

    Employer responsibility follows CACI No. 3720 (scope of employment). Negligent hiring, supervision or retention follows CACI No. 426. Both are published by the Judicial Council of California.

    Insurance

    How Much Insurance Does a Commercial Truck Carry?

    The law sets minimums. They are floors, not a measure of what any claim is worth.

    For-hire carriers hauling ordinary freight interstate in vehicles rated at 10,001 pounds or more must carry at least $750,000 in public liability coverage under 49 CFR 387.9. The minimum rises to $1,000,000 for oil and many hazardous materials, and to $5,000,000 for some bulk hazardous loads.

    Carriers that stay inside California have a parallel rule. Vehicle Code section 34631.5 requires a motor carrier of property to keep a combined single limit of at least $750,000, with a lower $300,000 floor for carriers running only vehicles under 10,000 pounds.

    Beyond the minimum there may be excess cover, a trailer policy or another company’s policy in the chain, and your own underinsured motorist coverage. The commercial vehicle settlement guide explains how these policies interact.

    $750KGeneral freight, interstate
    $1MOil and many hazardous materials
    $5MSome bulk hazardous loads

    Federal minimum levels of financial responsibility, 49 CFR 387.9.

    Close to Our Office

    Truck Crashes on the San Fernando Valley Freeways

    Our office is in Sherman Oaks, close to where the 405 and the 101 meet.

    Freight crosses the Valley on I-405 over the Sepulveda Pass, US-101 along the Ventura Freeway, I-5 on the east side, CA-118 across the north end and CA-170 between the 101 and the 5. Merges, interchanges and grades are where a heavy truck behaves least like the cars around it.

    A few legal points come up often on these roads. Trucks with three or more axles, and anything towing a trailer, are limited to 55 mph under Vehicle Code section 22406. The same trucks must use the right-hand lane or a designated truck lane under section 21655, with a limited exception on divided highways with four or more lanes in one direction. Freeway collisions are usually investigated by the California Highway Patrol, not LAPD, so the report comes from CHP. Where a work zone or road condition is involved, Caltrans or a contractor may be part of the picture, and the six-month public-entity claim deadline applies.

    Compensation

    What Compensation May Be Available After a Truck Crash?

    The categories a claim is built from. Amounts depend on the medical records.

    Medical ExpensesEmergency care, surgery, rehabilitation.
    Future Medical CareCare that continues after the claim ends.
    Lost IncomeWages lost while recovering.
    Reduced Earning CapacityWhere the injury limits future work.

    Evidence

    Evidence That Can Matter in a Truck Accident Claim

    In a truck case the carrier’s files matter as much as the scene.

    The Truck
    • Engine module and event data
    • Electronic logging device
    • Brakes and air system
    • Tires and wheels
    • Lights and reflective tape
    • Dashcam and forward camera
    The Carrier
    • Driver qualification file
    • Maintenance and inspection files
    • Dispatch and trip records
    • Drug and alcohol test records
    • Accident register
    • Lease and broker agreements
    The Scene
    • CHP or police report
    • Photographs and measurements
    • Skid and gouge marks
    • Debris and cargo
    • Witness accounts
    • Nearby business video
    You
    • Medical records
    • Photographs of injuries
    • Your vehicle and its data
    • Wage and work records
    • A written account, made early
    • Insurance correspondence
    Before your car is repaired or scrapped

    Your own vehicle can hold crash data and physical evidence of how the impact happened. If the injuries are serious, it is worth asking about preservation before an insurer arranges salvage.

    After a Crash

    What Should I Do After a Truck Accident?

    In this order, and only what is safe.

    1. 01Get Medical Care

      The same day if you can.

    2. 02Call Law Enforcement

      On a freeway that is usually CHP.

    3. 03Photograph What You Can

      The truck, its markings, the road.

    4. 04Write Down the Truck’s Details

      Company name, USDOT number, plates.

    5. 05Get Witness Details

      Before people leave.

    6. 06Keep Your Vehicle

      Do not let it be scrapped yet.

    7. 07Keep Every Record

      Bills, pay stubs, insurer letters.

    8. 08Be Careful With Statements

      The carrier’s insurer is not your insurer.

    9. 09Do Not Rush a Settlement

      A release is final.

    10. 10Get Advice Early

      Because of the records clock, not because of the lawsuit deadline.

    Where is the USDOT number?

    Under 49 CFR 390.21, carriers must mark the power unit with their name and USDOT number. It identifies the company whose operating authority the truck was running under, which is not always the name painted on the trailer.

    Our Process

    How Burg & Brock Investigates a Truck Accident

    What happens, and roughly in what order. The steps in a claim are laid out in more detail in our truck accident claim process guide.

    01Identify the Carrier

    USDOT number, operating authority, and who owned the tractor and trailer.

    02Send Preservation Letters

    To the carrier and anyone else holding records, data or the vehicle.

    03Request the Regulated Files

    Logs, maintenance, inspection, driver qualification and testing records.

    04Examine the Vehicles

    With qualified experts, where brakes, tires, load or data may matter.

    05Match Rules to Facts

    Which regulation applied, whether it was broken, and whether that caused the crash.

    06Find Every Policy

    Primary, excess, trailer and your own coverage.

    07Document the Injuries

    Treatment, work, and the effects that continue.

    08Negotiate or File Suit

    Building the case for settlement, and for court when that is what it takes. See how to sue a trucking company.

    Deadlines

    2Years*

    How Long Do I Have to File?

    Under Code of Civil Procedure section 335.1, a lawsuit for personal injury or wrongful death generally has to be filed within two years.

    *That is not the only deadline. If a public entity may share responsibility, for example over a road condition, a work zone or a government-owned truck, a written claim must usually be presented within six months under Government Code section 911.2, and a lawsuit then follows its own timetable under section 945.6. Claims for damage to a vehicle and other property fall under the three-year period in Code of Civil Procedure section 338.

    In practice the record-retention periods above often run out first.

    How Much Is a Truck Accident Case Worth?

    There is no honest figure before the injuries and the evidence are understood. These are the factors that move a case. We explain them further in truck accident settlements in California, and our page on the semi truck settlement calculator explains what online calculators can and cannot tell you.

    Questions

    Frequently Asked Questions

    What should I do after a truck accident in California?

    Get medical care, call law enforcement, and if it is safe, photograph the truck, its markings and the scene. Write down the company name and the USDOT number on the cab door. Keep your own vehicle until someone has decided whether it is evidence, and get advice early, because some of the carrier’s records can lawfully be discarded after six months.

    How long does a trucking company have to keep driver logs?

    At least six months. Under 49 CFR 395.8(k), a motor carrier must keep each driver’s records of duty status and supporting documents for no less than six months from the date it receives them. After that, the carrier can discard them unless it has been asked to preserve them.

    What are the hours-of-service limits for truck drivers?

    For interstate property carriers, 49 CFR 395.3 allows 11 hours of driving after 10 consecutive hours off duty, no driving after the 14th hour on duty, and a 30-minute break after 8 hours of driving. Drivers who stay inside California follow Title 13, section 1212.5, which allows 12 hours of driving and no driving after the 16th hour on duty.

    Can I sue the trucking company and not just the driver?

    Often, yes. A carrier can be responsible for an employee driver acting within the scope of the job, and separately for its own negligence in hiring, training, supervising or retaining the driver, or in maintaining the truck. Other parties, such as a loader, trailer owner or repair shop, may also share responsibility.

    What if the driver was an independent contractor?

    The label in the contract does not settle it. California’s jury instruction on disputed employee status, CACI No. 3704, treats the right to control how the work is done as the most important factor, alongside others. Even where the driver is not an employee, the carrier may be responsible for its own negligence.

    Do federal trucking regulations apply to a truck that never left California?

    Not always. The federal rules mainly govern interstate commerce. Trucks that operate only inside California are covered by state rules, including the Vehicle Code and Title 13 of the California Code of Regulations, which set their own hours limits and inspection requirements. Which set applies is one of the first things to check.

    Does a broken safety rule prove the trucking company was negligent?

    It can create a presumption of negligence under Evidence Code section 669, but only if the violation caused the injury, the harm was the kind the rule was meant to prevent, and you were in the group it was meant to protect. The presumption can be rebutted, so the link between the rule and the crash still has to be shown.

    Is the truck driver drug and alcohol tested after a crash?

    In some crashes, yes. Under 49 CFR 382.303, a carrier must test its surviving driver after a crash involving a death, and after one where the driver is cited for a moving violation and someone was treated away from the scene or a vehicle was towed. Whether the required tests were done, and when, can itself be evidence.

    How much insurance does a commercial truck have to carry?

    For-hire interstate carriers hauling general freight in vehicles of 10,001 pounds or more must carry at least $750,000 under 49 CFR 387.9, with higher minimums for oil and hazardous materials. California requires intrastate property carriers to carry at least $750,000 under Vehicle Code section 34631.5. These are minimums, not a measure of what a claim is worth.

    How long do I have to file a truck accident lawsuit in California?

    Generally two years for personal injury or wrongful death, under Code of Civil Procedure section 335.1. If a public entity may be responsible, a written claim is usually due within six months under Government Code section 911.2. Property damage claims generally have three years under section 338.

    Can I recover if I was partly at fault for the truck accident?

    Yes. California applies comparative fault, so your damages are reduced by your percentage of responsibility rather than barred. The defence has to prove both that you were negligent and that your negligence was a substantial factor in causing your own harm.

    How much does a truck accident lawyer cost?

    We handle truck accident cases on a contingency fee. There is no attorney’s fee unless there is a recovery. Case costs are separate from attorney’s fees, and both the fee percentage and how costs are handled are set out in the written fee agreement before anything is signed.
