RV pet harnesses — Center for Pet Safety 5-star crash data, 30-50 mph ratings, NHTSA human analog

The 2013 Subaru + CPS study that changed the conversation

In 2013 the Center for Pet Safety (a 501(c)(3) nonprofit) partnered with Subaru and MGA Research Corporation — an independent lab under contract to NHTSA — to run the first rigorous, FMVSS-style crash tests on commercially available pet harnesses. They used specially designed crash-test dog surrogates sized to real canine weights, not static pull tests. The results were stark: most popular harnesses failed catastrophically, allowing the 'dog' to become a projectile or suffer excursion far beyond survivable human-analog limits.

Only one harness in the initial round — Sleepypod Clickit Utility — consistently kept the surrogate from launching off the seat and provided substantial protection to both the pet and human occupants. The study used the same test methodology NHTSA applies to child restraints (FMVSS 213), creating a direct human-analog benchmark. Subsequent CPS work has refined the protocol; current certification requires passing dynamic tests at 30 mph with excursion limits that mirror child-seat standards.

• ›Test speed baseline: 30 mph frontal impact (real-world collision scenario)
• ›FMVSS 213 child-seat protocol adapted as the human-analog benchmark
• ›Most harnesses on the market at the time failed; only top performers limited excursion

What '5-star' and 'rated 30-50 mph' actually mean (or don't)

CPS does not hand out '5-star' ratings in the NHTSA NCAP sense; they certify products that meet their published Safety Harness Crash Test Protocol. Certified products appear on the CPS-certified list. Manufacturers may claim 'tested to 50 mph' or 'crash tested' using internal or third-party static/dynamic rigs, but without CPS protocol compliance and public results, the claim is unverifiable marketing. ASTM has since approved a new standard for dog harnesses in motor vehicles (2025), but CPS remains the independent, consumer-funded testing body with the longest public track record.

The 30 mph figure that appears in CPS materials and partner releases is the baseline dynamic test speed. Some newer certified products have been validated at higher energies, but the protocol floor is the 30 mph FMVSS-analog impact. Any harness advertising '50 mph rating' without a CPS certification link or published MGA-style report should be treated as unverified until the manufacturer supplies the raw data.

Current CPS-certified harnesses and crates (2026 snapshot)

The CPS certified products page lists carriers and kennels that have passed the current protocol (Gunner, Diggs, Lucky Duck, Cabela's GunDog, PawsInCar, etc.). For harnesses specifically, the 2013 top performer (Sleepypod) set the bar; later rounds and manufacturer submissions have added others that meet the excursion and attachment-strength criteria. Always cross-check the live CPS certified list before purchase — certification is voluntary and can be withdrawn if quality control slips.

For RV use the additional constraints are: the harness must work with the specific vehicle seat-belt geometry (many RVs have low or recessed latch points), must not interfere with the RV's own child-seat or LATCH anchors if present, and must survive the repeated vibration and temperature cycles of travel (CPS does not test long-term durability, only crash performance).

NHTSA human analog — why the child-seat protocol matters

By using FMVSS 213 test conditions and excursion limits calibrated to child dummies, CPS created a direct apples-to-apples comparison: if a 50-lb dog in a harness experiences forward excursion equivalent to what would be fatal or seriously injurious to a child in a certified car seat, the harness fails. This is the 'NHTSA human analog' referenced in every serious discussion of pet restraints. Static 'pull to 5,000 lb' claims on Amazon harnesses tell you nothing about dynamic performance in a 30 mph crash where the force vector, duration, and seat geometry all matter.

RV-specific installation realities

RV dinette and sofa seat belts are often not the same as automotive 3-point belts. Many are lap-only or have different anchor locations. A harness certified on a standard car seat may not perform the same when the attachment point is 4 inches lower or the belt angle is shallower. CPS testing uses standardized automotive seats; real RV geometry requires the renter to verify fit on the actual rig (or ask the host for photos of the belt path with the harness installed).

Best practice: buy a CPS-certified harness sized to your pet, install it in your own vehicle first, then test-install in the rental before departure. If the host's dinette belt geometry is incompatible, a crash-tested crate (also CPS certified) secured with cargo straps to the vehicle structure is the safer alternative.
