“Crash Tested” Is a Claim, Not a Result
Treat “crash tested” on a dog harness, crate or carrier as a claim to trace, not a fact to trust. The phrase has no fixed meaning. It can mean a company ran its own test to a standard it never published, or it can mean an independent lab tested that exact product in that exact size. Only the second is checkable.
The best-known independent program is run by the Center for Pet Safety (CPS), a nonprofit. CPS certification is voluntary, manufacturers pay to enter it, and it is granted per product and per size. Its best-known studies were sponsored by a car company. None of that makes the program worthless. It does mean you should read it the way you would read any label: who ran the test, who paid, and what exactly passed.
If nothing certified covers your dog's size, three rules still hold:
- Ride in the rear seat. CPS ran its carrier tests on a rear-seat bench.
- Attach a belt to a body harness, never a collar.
- Keep nothing loose, including the dog.
| If you see | It probably means | Your next step |
|---|---|---|
| “Crash tested,” nothing else | The maker's own test, standard unknown | Ask what standard, which lab, which size |
| “Adapted from” or “meets” a named standard | A test protocol exists; pass criteria may not be public | Ask for the pass criteria and the report |
| CPS Certified seal | Independent lab test, that product, listed sizes | Check the exact name and size on the CPS list |
What Can “Crash Tested” Actually Mean?
In practice the phrase covers three different things, and a label rarely tells you which one you are getting.
| Claim on the box | What it proves | What to ask |
|---|---|---|
| “Crash tested” (no detail) | Nothing you can check. Someone did something and called it a test | Which standard? Which lab? Which dog weight? Which size of this product? |
| Names a standard or protocol | A method exists. It may be adapted, and the pass line may be the maker's own | Is the pass criteria published? Is there a third party report? |
| Independently certified | A lab tested that product against published criteria, and all sizes passed | Is that exact product and size on the certifier's current list? |
On standards, the record is old. In a July 2015 press release, CPS and Subaru of America wrote that while many crate and carrier makers claim to be crash-tested, "there are currently no test protocols or performance standards in the U.S. to substantiate these claims." That is a 2015 statement. We did not verify whether a U.S. standard exists now, so read it as history, not as today's status.
What CPS did in 2015 is instructive. Its carrier study and crate study picked products that already claimed "testing," "crash testing" or "crash protection," and tested them at MGA Research Corporation, which CPS describes as a NHTSA-contracted lab. The result pages describe connections releasing, stitching failing, a test dog launched, a door failing and plastic fracturing. A wire crate held down with rubber straps slid into the seatback fixture. The claim on the box did not predict the result.

The dogs in these tests are not real. CPS says it does not use real dogs; it uses engineered test dogs (simulants) of 15, 20, 45, 75 and 110 lb. The carrier test condition is roughly 30 mph, which CPS says it borrows from the federal test for child car seats (FMVSS 213).
What Does CPS Certification Cover, and Who Pays for It?
CPS certification means a manufacturer volunteered, paid, and passed, one size at a time. Its certified page (read live on 29 September 2026) describes the program as "a voluntary commitment by the manufacturer" to meet independently developed safety standards, monitor quality control and be truthful in marketing.
Per product and per size. A legacy CPS manufacturer page says certifications "are assigned by size," and that all sizes of a product must pass to qualify. A seal on the medium does not vouch for the small or the large.
Who pays. The same legacy page says CPS requires "payment of an examination fee and product certification fee," varying with the number of sizes tested, because CPS is a nonprofit that is "not fully funded." The amounts are not published. It also says only products that pass are awarded a seal. We are reporting what CPS wrote, and we are not characterizing it further.
The live URL for that manufacturer page now redirects to CPS's homepage, so we read its text from an Internet Archive capture dated 4 March 2026. The page is a legacy one: it says the certification program was announced on 15 July 2014. We could not re-confirm the fee wording or the limits below on a live CPS page, so treat them as CPS's stated terms from an archived copy, and ask CPS for current ones.
CPS says two different things about money. The live certified page also says CPS "does not accept funding from pet product manufacturers." The legacy page says manufacturers pay exam and certification fees. CPS presents fees as payment for a service, not funding, and we are not going to resolve the wording for you. You should know both exist.
The Subaru sponsorship. CPS's 2013 harness study was done "in partnership with Subaru of America", per CPS's own page. Its 2015 carrier results are labeled "sponsored by Subaru," and the crate and carrier studies were run under a renewed Subaru partnership. In its FAQ, CPS says the sponsor's funding is "for these studies only." Subaru is a car company, and it appears in CPS's own release as a co-announcer of the results. We found nothing in these documents about Subaru choosing outcomes, and we are not suggesting it did.
The limits CPS states for harnesses, as of that archived page:
| Criterion | What CPS states |
|---|---|
| Excursion (how far the head travels forward) | Under 32 inches for XXS, XS, S and medium test dogs; under 36 inches for large and XL |
| How excursion is measured | From the start position to the furthest forward point of the muzzle stop during the dynamic test |
| Extension tether or zipline accessory | Disqualifies the harness |
| Hardware and webbing | Migration must stay within a per-size range; hardware and stitching must not fail totally |
| Weight | CPS says it has not tested most products past 75 lb; its FAQ mentions one harness certified to 90 lb |

One more caution from CPS's own 2013 study page. A quasi-static test (pulling a harness on a solid dog-shaped form until it breaks) is a screen, and CPS says "meeting the preliminary testing requirement is no indicator of crash protection." Seven harness brands moved on to crash testing in 2013.
Harness, Crate or Carrier: What Was Each Tested For?
The three were tested under different conditions, so their results do not rank against each other. The table shows what CPS looked at for each and where the gaps are.
| Restraint | Where CPS tested it | What CPS looked at | Size limits | What failed in 2015 tests | Where it fits |
|---|---|---|---|---|---|
| Harness | Dynamic crash test on a seat assembly | Excursion, hardware and webbing migration, no total hardware or stitching failure, no extension tether | Excursion limits vary by simulant size; most products untested past 75 lb | CPS says strength screening is "no indicator of crash protection" (2013 study) | A dog that will ride on a seat and can wear a fitted body harness |
| Crate | Simulated cargo area, with strength-rated tie-down straps | Whether it stayed connected and contained the dog | Only crates under $1,000 were considered; up to a 75 lb simulant in the top performer's test | A door failed; plastic fractured; a wire crate on rubber straps slid into the seatback fixture | A dog that rides in a cargo area, with anchors that fit the crate |
| Carrier | Rear-seat bench, roughly 30 mph, FMVSS 213 test conditions | Staying connected and containing the test dog | Small-dog simulants (the results we read used 15 lb); CPS pointed small dogs and cats here | Connections releasing; stitching failing; a simulant launched | Cats and small dogs |
| Nothing | Not tested | None | None | Not applicable | Nowhere; a body keeps moving at the vehicle's speed until something stops it |
CPS's 2015 recommendation was a top-performing carrier for small dogs and cats, and either the top-performing crate with tie-down straps or a CPS Certified harness for medium and large dogs. That advice is now over a decade old and names products that may have changed, so we have not repeated the product names. Check the current list.
Cats and small dogs in carriers are where a crash claim matters most. Our guide on getting a cat to the vet covers the calm, low-stress side of carrier use.
A word on Consumer Reports. Consumer Reports has a page called "Best Dog Harnesses and Carriers for Travel" (updated 11 February 2025). By its own intro, CR's volunteer dogs "try out two harnesses and two travel carriers that have been independently tested and certified as safe by the Center for Pet Safety." So CR ran fit and usability trials on products CPS had already certified. It did not crash test them. We could only read the free introduction, so we attribute nothing else to that page. The page also carries an affiliate-commission disclosure.
How Do You Fit One So the Test Still Applies?
A certified product only earns its result when it is used as tested. A short checklist:
- Belt to harness, never to a collar. A collar puts a crash load through the neck. Rhode Island's own statute on transporting animals in open vehicles specifies a harness "by means other than neck restraints."
- Use the exact size that was certified. A seal on one size says nothing about another.
- No extension tethers or zipline accessories. CPS disqualifies a harness with one.
- Fit the harness snugly on the body, so hardware and webbing have little slack to migrate.
- Size and anchor the crate as its instructions say. CPS tested crates on strength-rated tie-down straps, not bungee or rubber ones.
- Rear seat, nothing loose. Loose items and unrestrained passengers are part of the same problem.

A walking harness is a different tool from a car restraint: it makes no crash claims, and our harness, collar and head halter guide is about leash walking only. A parked car has its own hazard, covered in our heat safety guide.
What Does the Law Say, and What Can Nobody Tell You?
We read five statutes, each on the date shown, and none is a blanket rule requiring a dog to be restrained in an ordinary closed cabin. We did not survey all 50 states, so this table shows five, and it is not a count of anything. Laws change, so check your state's current code.
| State and statute | Text as read on | What it covers |
|---|---|---|
| Hawaii, HRS 291C-124(b) | 14 Feb 2025 (archive copy) | No person may hold in their lap, or allow in the driver's immediate area, an animal that interferes with control of the vehicle |
| Rhode Island, R.I. Gen. Laws 31-22-28 | 3 Aug 2025 (archive copy) | Transporting an animal on or in an open air motor vehicle unless enclosed, in a person's physical control, or restrained by a purpose-made harness "by means other than neck restraints"; fine up to $50, then up to $200 |
| Connecticut, CGS 14-272b | 28 Sep 2026 (archive copy) | Pick-up truck open rearward compartment only: the dog must be secured or protected against being thrown, falling or jumping |
| Maine, 29-A M.R.S. 2087 | 29 Sep 2026 (live) | Open vehicles such as pickups and convertibles; dog protected against falling, jumping or being thrown; farm and hunting exceptions |
| Massachusetts, M.G.L. c. 90, 22H | 24 Jul 2026 (archive copy) | An animal in the load space of a vehicle on a public way must be enclosed, racked to 46 inches, cross-tethered, in a secured container or cage, or otherwise protected; fine of not less than $50 |
Read them for what they say. Hawaii's applies only when the animal interferes with the driver. The other four are about open truck beds and open vehicles, not a dog on a back seat. A restraint you choose for a closed car is your call, not a statute's.
What nobody can tell you here. This guide makes no claim about how often dogs are hurt in car crashes, because we did not find a primary source with a rate we could check. You will see dramatic figures online for the force on a dog in a crash. We could not trace a published measurement behind them, so we don't use them. The mechanism needs no number: a body keeps moving until something stops it.
The most useful thing a “crash tested” label can do is send you to a name, a size and a list you can check. The least useful is to end the search. If the box gives you no standard, no lab and no size, you have been told nothing yet.
Five Questions to Ask Before You Buy
Answer these at the shelf, in this order.
- Which standard or protocol was used, and is it named?
- Which lab tested it, and is a report available?
- Which sizes passed? Certification is per size.
- Is the exact product on the certifier's current list? For CPS, check the list. It is script-rendered and its contents change.
- Does my dog fall inside the tested weights? CPS says it has not tested most products past 75 lb, and larger dogs are, in its words, in a quandary.
Bottom line: “crash tested” proves nothing until you can trace it to a standard, a lab, a size and a list. CPS certification is the most checkable option we found: voluntary, manufacturer-paid (amounts unpublished), granted per size, with its best-known studies sponsored by Subaru, and with CPS also saying it accepts no manufacturer funding. Belt to a body harness, never a collar. If nothing certified fits your dog, use the rear seat and keep everything secured. We have no affiliation with CPS, and we recommend no product here.
FAQ
Is “crash tested” the same as Center for Pet Safety certified?
No. “Crash tested” has no fixed meaning; CPS certification is a specific voluntary program with per-size testing. In 2015, CPS and Subaru said no U.S. standards existed to back up crash-test claims, and we did not verify whether that has changed.
Can I clip a seat belt to my dog's collar?
No. Attach a belt or tether to a body harness. A collar concentrates a crash load at the neck, and none of the CPS test criteria we read evaluates a collar as a restraint.
Is a crate safer than a harness?
We found no head-to-head test. CPS tested each under different conditions, so the results do not rank against each other.
Is it illegal to drive with a dog loose in the car?
We did not survey all 50 states. In the five statutes we read, none is a blanket rule for a closed cabin; see the statute table above. Check your state's current code.
Does a certified harness cover every size?
No. CPS assigns certification by size, and all sizes must pass. Check the exact product and size, and remember CPS says most products are untested past 75 lb.

A Note on Scope
This guide explains how to read product safety claims and summarizes published test pages and statutes. It is not veterinary, legal or engineering advice, and no restraint eliminates the risk of a crash. It isn't a substitute for advice from a veterinarian about an individual dog. Laws differ by place and change over time, so check your own state's current code. If a dog has been in a crash, see a vet even if it looks fine.
