Quick Answer Almost always your own comprehensive coverage — unless you can prove the rock came from the truck’s load, which is where the truck’s liability lives. A rock lying on the pavement and flung by a tire is a road hazard with nobody’s negligence attached: your claim runs through comprehensive as a no-fault glass claim, deductible applied. A rock spilling from an uncovered or leaking load is different — Texas law (Transp. Code §725.021) requires loose materials to be contained, covered, and secured, and an operator who showers the highway with gravel is answerable for it. The catch is proof: the truck’s identity plus evidence the material came off the load, which in practice means a dashcam. And no, the “not responsible for broken windshields” bumper sticker doesn’t change any of this.

Scenario one: the rock was already on the road. Debris kicked up by another vehicle’s tires — even a truck’s — is generally treated as a road hazard, because flinging a rock nobody knew was there isn’t negligent driving. Nobody to bill means your own policy answers: a rock strike in flight is the classic comprehensive claim — the no-fault lane that also handles hail and [vandalism](https://dgcollision.com/answers/does-insurance-cover-a-keyed-car/) — with your comprehensive deductible applied. Texas has no zero-deductible glass law ([that’s Florida, Kentucky, and South Carolina](https://dgcollision.com/answers/is-windshield-replacement-free-in-texas/)), so the deductible math is real: a windshield alone can land under it, which turns small strikes into cash repairs; optional full-glass endorsements exist and are worth a look at renewal if you run gravel-heavy routes. Scenario two: the load itself shed the rock. Texas Transportation Code §725.021 requires vehicles hauling loose material — dirt, sand, gravel, wood chips — to be equipped and maintained so the load can’t blow or spill: enclosed beds without gaps, secured coverings, closed tailgates. An operator whose uncovered load is actively raining aggregate onto a highway is violating that duty, and the damage it causes belongs on that operator’s liability insurance, not your comprehensive. Now the honest part: winning that claim requires two proofs — the truck’s identity (carrier name, DOT number, or plate) and evidence the material came off the load rather than off the road. An eyewitness account of gravel streaming off an uncovered trailer works; “a rock appeared near a truck” doesn’t. In practice, dashcam footage is what separates the two scenarios, and it’s the single best $100 a DFW commuter can spend on this problem. About the sticker: mudflap signs reading “stay back — not responsible for broken windshields” are not contracts, and in our reading a posted disclaimer doesn’t erase a legal duty to secure a load — a company can’t sign itself out of §725.021 with a decal. What the sign does do is warn you into following distance, which is genuinely the best prevention. When a strike does happen: photograph the damage and location promptly, note the truck if you safely can, save the footage, and then run the ordinary [file-or-pay math](https://dgcollision.com/guides/file-claim-or-pay-out-of-pocket/). One more modern wrinkle before any glass work: if a camera rides your windshield, replacement is a calibration event — priced and scheduled with the glass, never skipped. Related Questions ## ASKED ALONGSIDE THIS ONE Will a rock-chip claim raise my rates? + A: A comprehensive glass claim is a no-fault claim — no surcharge points, nothing on your driving record, and Texas rule 28 TAC §5.7016 protects against nonrenewal based solely on weather and other not-at-fault claims (with a two-in-twelve-months limit on the not-at-fault kind). What can move: claims-free discounts, and the picture painted by several claims stacked close together. That’s the same honest answer as the hail-claim version of this question. The chip is tiny. Repair, replace, or ignore? + A: Small chips out of the driver’s sightline can often be resin-repaired cheaply and quickly — the thing they can’t do is wait, because temperature swings walk a chip into a crack, and a crack means replacement. Once replacement is on the table the deductible math and the camera-calibration step both enter. The cheap move is the fast one. I got the trucking company’s name. What do I actually do with it? + A: Report the incident to the carrier’s insurance as a third-party property claim, with your evidence: footage or witness account, photos, time and location. Expect them to ask how you know the rock came from the load — that’s the whole case. If it stalls and the damage is modest, filing on your own comprehensive and letting the deductible math govern is often the pragmatic end; your carrier can pursue theirs if the evidence supports it. Does the rock damage ever go beyond glass? + A: Regularly — hood and roof-edge chips, cracked trim, a broken sensor housing. Body damage from the same event belongs on the same claim, and paint chips deep enough to reach metal are worth fixing before DFW weather finds them: published refinish rows start at $200–$500 for spot work. One documented estimate covering glass and body keeps the claim whole.
