When an item falls off a truck and hits your car, the truck driver and the trucking company are almost always on the hook for the damage. Federal law requires every commercial carrier to secure its load so nothing falls, spills, or blows free,1eCFR. 49 CFR 393.100 – Applicability and General Requirements of Cargo Securement Standards and when something separates from the trailer and strikes you, that failure is negligence. The hard part is proving it. What you do in the first few minutes shapes everything that comes after.
At the Scene
Pull over safely and call 911 or local police. An official report creates a neutral record of what happened, where the debris landed, and what it damaged. Even if the truck is long gone, that report anchors your insurance claim. If you’re hurt, get medical attention before you worry about evidence.
If the truck stopped or you can still see it, write down the license plate and look for the USDOT number on the cab or trailer. Federal regulations require commercial vehicles to display that identifier on both sides, preceded by the letters “USDOT,” in lettering readable from 50 feet.2eCFR. 49 CFR 390.21 – Marking of Self-Propelled CMVs and Intermodal Equipment Grab the company name from the door or trailer too. Those details let you find the carrier’s insurance through the FMCSA’s public database.
Photograph everything. The debris on the road. The object lodged in your car. The damage. The truck if it’s still there. Wide shots that show the debris trail leading back toward the truck help later. Get contact information from any witnesses. A bystander who saw the item come directly off the trailer, rather than get kicked up from the pavement, can make or break the claim.
Dashcam Footage
If you have a dashcam, that footage is your single best piece of evidence. Video of the moment an object separates from the truck in front of you ends most arguments about where the debris came from. Keep the original file unedited and make a backup. If the case goes to court, the recording has to be authenticated as unaltered, which is straightforward when the original with intact timestamps still exists.
Which Insurance Pays
How your own policy treats the claim turns on a detail most drivers don’t think about: whether the object was still in the air when it hit you, or already lying on the road.
Falling Objects Trigger Comprehensive Coverage
Debris that flies off a truck and strikes you while airborne is a comprehensive claim. Comprehensive handles damage from events outside your control that aren’t collisions with another vehicle, including falling objects, flying rocks, and cargo that separates from the truck ahead.3Allstate. What Is Comprehensive Insurance You pay the deductible; your insurer covers the rest up to the vehicle’s actual cash value.
Road Debris Triggers Collision Coverage
If you hit an object already sitting on the pavement, that’s a collision claim. Collision applies when your vehicle strikes something, whether a car, a guardrail, or debris in your lane.4The Balance. What to Do If You Hit Something in the Road or Highway The deductible and payout work the same way, but the classification affects your rates differently.
Subrogation Against the Carrier
When you can identify the truck, you don’t have to choose between filing on your own policy and filing against the carrier’s. Many drivers file on their own comprehensive or collision coverage to get repairs started, then let their insurer pursue the trucking company through subrogation. Your insurer steps into your shoes and demands reimbursement from the carrier’s insurer, including your deductible.5The Hartford. Subrogation: What It Means for Auto Insurance A full recovery gets your deductible back. A partial recovery gets you part of it.
When the Truck Didn’t Stop
This is the most common and most frustrating version. The driver may not even know anything fell. With no plate and no USDOT number, you can’t go after the carrier’s insurance, so your comprehensive coverage is the main safety net. Because flying debris counts as a falling object, you can file comprehensive without identifying the other vehicle.
Uninsured motorist coverage is less reliable here. Many policies require actual physical contact between your car and the other vehicle itself, and some states draw a line between debris that was still falling (which may qualify) and debris that was already on the road (which usually doesn’t).6E&L, LLP. Uninsured and Underinsured Motorists Read your policy or call your agent. Dashcam footage matters most in these cases. If you caught the plate, USDOT number, or company name on video, the hit-and-run problem disappears.
Why the Trucking Company Is Liable
The legal claim is negligence. Every commercial motor vehicle on public roads has to load and secure cargo so nothing leaks, spills, blows off, or falls.1eCFR. 49 CFR 393.100 – Applicability and General Requirements of Cargo Securement Standards That duty covers everything from steel beams to loose gravel to a mattress in a pickup bed. When something separates and hits you, the securement failure is the negligence.
You’re rarely limited to suing the driver alone. Under respondeat superior, an employer is liable for harm its employees cause while doing their job. A driver hauling cargo for a carrier is squarely within that scope, so the trucking company shares liability. This matters practically: the company’s commercial policy carries far higher limits than any driver’s personal assets. The USDOT number you wrote down at the scene is what gets you to that deeper pocket.
Those “Not Responsible for Damage” Signs
Gravel trucks and flatbeds often post signs reading “Stay Back 200 Feet” or “Not Responsible for Broken Windshields.” These are legally meaningless. A private company cannot exempt itself from federal cargo securement rules by painting a disclaimer on a mudflap. Courts treat the signs as informational, not as a waiver of liability. If a tarp was missing, a strap failed, or a tailgate was left open, no sign protects the carrier from a negligence claim. Don’t let one talk you out of a legitimate claim.
How Following Distance Affects Your Payout
Adjusters and defense attorneys will look hard at how closely you were following. If you were tailgating, the carrier’s insurer will argue you contributed to your own damage by not leaving enough space to react. Most states use some form of comparative negligence, which reduces your recovery by whatever share of fault gets pinned on you. Tailgating at highway speed and taking a hit from debris you could have steered around with a safer gap might cost you 10, 20, or even 30 percent of the payout.
The standard safe following distance behind a large truck is roughly three to four seconds at highway speeds. Your dashcam footage, if you have it, shows exactly how far back you were. Adjusters know this and they check.
Comparative negligence rarely wipes out the claim entirely. If a 50-pound object launches off a flatbed at 65 miles per hour, no following distance would have saved you. The analysis is fact-specific, and the carrier’s insurer bears the burden of showing you could have avoided the collision.
Filing the Claim
Start with the trucking company’s insurer. Your demand package should include the police report, photos of the debris and damage, the USDOT number or company name, witness statements, repair estimates from at least two shops, and medical records if you were injured. An adjuster will review the file and may inspect both vehicles. Property-damage-only claims with clean evidence often resolve in 30 to 60 days.
If the insurer denies the claim or lowballs you, small claims court is an option for smaller amounts. Maximum limits vary by state but generally fall between $2,500 and $25,000, and you can file without a lawyer. For larger claims or injuries, a civil lawsuit lets you use discovery to request the carrier’s maintenance logs, driver training records, and inspection history, which often reveal a pattern of securement violations. Personal injury attorneys typically work on contingency, so there’s no upfront cost.
Watch the Repair Estimate
Windshield replacement runs anywhere from $250 to $600 on a standard vehicle. If your car has rain-sensing wipers, lane-departure cameras, or other driver-assistance tech behind the glass, expect $1,000 or more, because those systems need recalibration after the swap. Check whether the insurer’s estimate specifies aftermarket parts instead of original equipment manufacturer (OEM) components. Aftermarket panels and glass are cheaper but may not fit as precisely or match the factory finish. Many states require insurers to disclose non-OEM parts, and you have some leverage to push back, especially on a newer vehicle. Get your own estimate from a shop you trust before accepting the adjuster’s number.
What You Can Recover
- Repair costs: the full expense of returning your vehicle to pre-accident condition, including parts, labor, and paint.
- Rental car: reasonable rental costs while your car is in the shop.
- Diminished value: even after a perfect repair, a car with accident history is worth less on resale. In most states, you can file a diminished value claim against the at-fault driver’s insurer to recover that loss.7Kelley Blue Book. Diminished Value of a Car: Estimations After an Accident
- Medical expenses: emergency treatment, follow-up care, and rehabilitation if debris caused injuries.
- Lost wages: income you missed because of injury or time spent dealing with repairs.
- Pain and suffering: compensation for physical pain and emotional distress, available only through a lawsuit or negotiated settlement.
Diminished value is the one people most often leave on the table. A car hit by falling debris and repaired will show up in vehicle history reports, and dealerships and private buyers pay less for it. Depending on the vehicle’s age and value, that claim alone can add thousands to your recovery.
Deadline to File
Every state sets a deadline for filing suit after property damage or injury, and missing it kills the claim entirely. For vehicle property damage, deadlines run from one to six years depending on the state. Personal injury deadlines sometimes differ from property damage deadlines in the same state, and they’re often shorter. If a government vehicle caused the damage, many jurisdictions require an administrative notice within as little as 120 days before you can even sue.
Don’t assume you have years to decide. Some of the most populated states give you two years on property damage, and the clock starts the day the debris hit your car, not the day you noticed hidden damage. File your insurance claim right away and talk to an attorney within the first few weeks if you’re considering a lawsuit.
Taxes on a Settlement
How a settlement is taxed depends on what the money compensates. The portion covering property damage to your vehicle is not taxable up to your adjusted basis in the car, and generally doesn’t need to be reported.8Internal Revenue Service. Settlement Income You do have to reduce your cost basis in the vehicle by that amount. Anything above your basis is taxable.
Settlements for personal physical injuries or physical sickness are excluded from gross income entirely, including compensation for medical bills and pain and suffering, as long as the damages relate to a physical injury.9Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness Emotional distress on its own doesn’t qualify unless it stems from a physical injury. Punitive damages are always taxable. If your settlement bundles property damage, medical costs, and emotional distress into a single payment, the allocation between categories determines what you owe, so ask for the agreement to break each component out separately.
