A rock from a truck cracked my windshield — who pays?

Quick answer
A rock from a truck is usually handled under your own comprehensive coverage, subject to your deductible. Road debris kicked up by a tire is generally treated differently from an unsecured load that falls off a vehicle. Note the details if it is safe to do so, and check with your insurer on how to proceed.
Is a truck liable for a rock hitting my windshield?
In most cases, a rock that cracks a windshield on the highway is road debris kicked up by a tire rather than something that fell off a truck. That distinction matters for how the loss is handled. Debris already on the road, thrown up by a passing vehicle, is generally treated as a comprehensive loss on your own policy — the same as any stone the road throws at the glass.
A load that was not secured and falls off a truck — gravel spilling from an uncovered bed, or a piece of cargo that comes loose — is a different situation, and how it is handled depends on the circumstances and the insurer. The general approach is to record what you can safely observe and let the insurer sort out the coverage path.
Either way, the windshield still needs fixing, and comprehensive coverage on your policy is what handles the glass while any question of fault is sorted out separately. The shop confirms coverage, orders the glass matched to your VIN, and bills the insurer directly, so the repair is not delayed while the cause is settled.
Road debris vs an unsecured load
Road debris kicked up by a tire
- A stone already on the road, thrown by a passing vehicle.
- Usually handled as a comprehensive loss on your own policy.
- Subject to your comprehensive or glass deductible.
- No need to identify the other vehicle.
A load that fell off a truck
- Gravel or cargo that came loose from an uncovered or unsecured bed.
- A different situation that depends on the circumstances.
- Note the plate, location, and time if it is safe to do so.
- Check with your insurer on how to proceed.
Either way, the windshield still needs fixing. Comprehensive coverage handles the glass while the question of fault is sorted out separately.
Note the details if it is safe
If a load fell off a truck, the plate number, the time, the road, and a photo of the damage help the insurer. Do not chase the vehicle or drive unsafely to read a plate. See our guide on what to do when a rock hits your windshield.
More questions about trucks and windshield damage
Can I claim against a truck that cracked my windshield?
A rock already on the road and kicked up by a tire is usually a comprehensive loss on your own policy. A load that fell off a truck is a different situation; note the details if it is safe and check with your insurer on how to proceed rather than assuming fault.
A gravel truck broke my windshield — who pays?
If gravel spilled from an uncovered bed, that is an unsecured-load situation and how it is handled depends on the circumstances. Record the plate, time, and location if it is safe, then check with your insurer. The glass itself is still a comprehensive loss on your policy.
Do I pay the deductible when a truck throws a rock?
Usually, yes — road debris kicked up by a tire is a comprehensive loss subject to your deductible, and full glass coverage on some policies lowers or removes that figure. Whether the truck is pursued separately is a matter for the insurer.
