How A4 Ranks US Auto Transport Companies
A4 Auto Transport publishes independent rankings and reviews of US auto transport companies. This page documents exactly how those rankings are built: the scoring criteria, the data we use, how often we refresh, our editorial policy, and how to flag a correction. Nothing in our rankings or reviews is for sale. No carrier can pay for placement.
Our independence policy
A4 is a broker-research site. Our revenue comes from lead fees — when a reader requests a quote through A4 and we connect them with a carrier in our vetted network, the carrier pays us a commission on the booking. That is the entire commercial relationship. Rankings, reviews, and scorecards are decided by the editorial team and are not influenced by lead-fee payments, carrier advertising, or any other commercial arrangement.
A carrier’s willingness to pay for leads has no effect on their position in our rankings. Some of the highest-ranked carriers on A4 don’t accept leads from us at all. Some of our lead-partner carriers are ranked mid-pack. The two systems are separate.
If we ever run sponsored content or a carrier-funded section, it will be visibly labeled as such and excluded from the editorial rankings. As of the publication date of this page, A4 has no sponsored content on the site.
Scoring criteria
Every auto transport company reviewed on A4 is scored on five dimensions, each weighted to reflect what shippers actually care about:
| Dimension | Weight | What we measure |
|---|---|---|
| Price accuracy | 25% | How closely the initial quote matches the final bill. Carriers whose final bills routinely exceed the initial quote are scored down. |
| On-time performance | 20% | Share of shipments that dispatch within the quoted window and deliver within the quoted transit time, from our tracked shipment records. |
| Coverage | 15% | Geographic reach — which states, routes, and vehicle types the carrier actually services, not just which they claim. |
| Insurance & safety | 15% | FMCSA safety scores, current USDOT and MC numbers, cargo and liability insurance limits, damage-claim resolution record. |
| Customer feedback | 25% | Aggregated verified reviews from BBB, Trustpilot, Google, and our own post-shipment surveys. Verified reviews weighted higher than unverified. |
Each dimension is scored 0–10, combined into a weighted total, and converted to a 5-star rating. A carrier must clear a minimum threshold on every dimension to be ranked at all — a carrier with a 9/10 on price but a 3/10 on insurance isn’t in our rankings, period.
Data sources
Our scores combine four data layers:
- Our own network data — billing records from shipments we’ve brokered and tracked since 2021. This is our primary source for price accuracy and on-time performance, because it’s the only dataset that tracks a single shipment from initial quote through final delivery.
- FMCSA public records — the Federal Motor Carrier Safety Administration’s database (safer.fmcsa.dot.gov). Used for USDOT/MC verification, insurance on file, safety scores, and operating authority. Every carrier review on A4 links to its FMCSA record.
- Aggregated third-party reviews — BBB, Trustpilot, Google Business Profile, and transport-specific review sites. We weight verified reviews (a buyer can demonstrate they actually shipped with the carrier) above unverified.
- Direct shipper surveys — post-delivery surveys sent to shippers who book through A4. Response rate is 30–40%, which is high for post-transaction surveys, and the results feed back into our on-time-performance and customer-feedback scores.
How often we update
- Carrier rankings — refreshed quarterly, plus any time a carrier’s FMCSA status changes materially (safety score drop, insurance lapse, operating authority revoked).
- Cost data — load-board base rates are refreshed monthly; per-route cost guides are re-reviewed quarterly.
- State pages — re-reviewed annually on the page’s anniversary, plus after any major state regulatory change that affects auto transport (e.g., emissions rules, inspection requirements).
- Money page and methodology page — re-reviewed every six months.
Every page on A4 shows a “Reviewed April 26, 2026” line in the byline. If you see a date older than the cadence above, it’s overdue for review — that’s on us and we’d appreciate the flag.
Who writes and reviews
Every A4 article has a named author and is reviewed by the A4 editorial team. Bilal, A4’s founder, edits all commercial-intent content (cost guides, carrier reviews, state-level shipping pages) and signs off on every carrier scorecard.
Ghostwritten and AI-assisted content is not accepted on A4 without disclosed human editorial review. If an article is substantially assisted by an AI tool during drafting, it still goes through the full editorial fact-check process — every figure, every carrier claim, and every price range is verified by a person before publication.
What we won’t publish
There are a few things A4 deliberately doesn’t do:
- Affiliate-only “reviews.” We won’t review a carrier we’ve never actually shipped with and won’t run a scorecard we can’t back with data.
- “Top 10” listicles from a press release. If a list isn’t constructed from our own scoring, we don’t publish it.
- Undisclosed sponsored content. If a carrier sponsors anything, it’s labeled and kept out of rankings.
- Recycled 2019 cost data. Cost figures are dated. If we can’t date a figure to within the last 12 months, we don’t use it.
- Carrier content as a “guest post.” Carriers can respond to our reviews in the comments or via [email protected], but they don’t publish on A4 under their own byline.
Corrections policy
If you find an inaccuracy in anything A4 has published — a cost figure, a carrier claim, a transit time, a state regulation — email [email protected] with the URL and the specific claim you’re flagging. Our process:
- Acknowledged within 2 business days.
- Investigated by the editorial team. If the claim is a matter of cited third-party data (e.g., FMCSA filings), we verify against the source; if it’s our own data, we cross-check against billing records.
- If the claim is wrong, we correct it within 48 hours of the investigation concluding, and add a dated correction note at the bottom of the affected page.
- If the claim is right, we explain why and include the sourcing.
Corrections are listed on each page permanently — we don’t quietly edit and move on. We want the public audit trail.
