Bringing your furry best friend along for car rides is one of the joys of dog ownership, but safety should always come first. After 8 years of relentless innovation—more time than the Romans took to build the Colosseum—the Impact Harness emerges as the gold standard in crash-tested dog car harnesses. This isn’t just any restraint; it’s engineered with a single piece of 4,000-pound tubular webbing reinforced by bar tacking, meeting Federal Motor Vehicle Safety Standards (FMVSS) originally designed for child seats. Whether you’re cruising highways or navigating city streets, this harness ensures your dog stays secure without compromising comfort.
For pet owners prioritizing road safety, the Impact Harness integrates seamlessly into your vehicle’s seatbelt system—no extra straps needed. It’s ideal for dogs of all shapes and sizes, thanks to four adjustment points for a custom fit.

Key Features of the Impact Harness
What sets the Impact Harness apart as a top crash-tested dog car harness? It’s built for real-world performance. Constructed from a single, ultra-strong webbing piece, it withstands extreme forces while remaining lightweight and breathable. All-steel nesting buckles provide durability that outlasts plastic alternatives, and the rear leash attachment keeps your dog positioned safely during travel.
Recommended exclusively for car use, this harness has undergone rigorous testing at university facilities using FMVSS protocols with anatomically accurate dog dummies—no live animals involved. Maintenance is simple: spot clean or hand wash, then air dry. For detailed guidance, refer to the product instructions.
Owners rave about its comfort during long trips. One experienced dog parent shared, “My 60-pound Labrador barely notices it, and it held firm during sudden stops.” This harness prevents common issues like forward lunging, reducing injury risk in collisions.

Sizing Guide for Perfect Fit
Proper sizing is crucial for safety and comfort in any crash-tested dog car harness. The Impact Harness uses one continuous webbing piece, making it highly adjustable across body types. Base your choice on weight, and size up if your dog is at the range’s edge—better a looser fit than too tight.
Here’s the official size chart:
| Size | Dog Weight |
|---|---|
| Small | 10 – 25 lbs (5 – 11 kg) |
| Medium | 25 – 50 lbs (11 – 23 kg) |
| Large | 50 – 75 lbs (23 – 34 kg) |
| X-Large | 75 – 108 lbs (34 – 49 kg) |
Measure your dog’s girth at the widest point behind the front legs for confirmation. For larger breeds, pair it with a [best dog seat belt for large dogs](https://dogcarestory.com/best-dog-seat-belt-for-large dogs/) to enhance stability.
In-Depth Crash Testing Results
Safety claims mean little without proof. The Impact Harness has been crash-tested up to 108 lbs at premier facilities like the University of Michigan (2016) and Calspan (2020), adhering to evolving PPSC guidelines. Initial tests passed for up to 130 lbs, but refinements to dummy accuracy and standards ensured compliance with the latest protocols.
These tests simulate high-impact scenarios, measuring chest acceleration and head injury criteria—metrics borrowed from child safety research. Videos of the tests (using weighted dummies) demonstrate the harness’s integrity: no detachment, minimal displacement. As industry leaders, manufacturers commit to ongoing updates, setting a benchmark for dog car restraints.
