Fleet command, DataQ challenges, hazmat, CSA monitoring, carrier vetting, accident preventability, audits, drug & alcohol, training and more — twelve specialized X3 products, plus a developer API, all from one company that does the work for you.
Each X3 product owns one slice of FMCSA compliance. Use one — or let us run the whole stack as your outsourced safety department.
Explosives to corrosives — correct placards, shipping papers, security plans and HM registration. Get one wrong and it's an out-of-service order; we make sure you never do.
Everything that powers the X3 products is available to build on. One REST API gives you verbatim federal regulations, a 67,000-document compliance knowledge base, and live carrier safety data — by USDOT number, updated daily.
Proprietary compliance & strategy documents — the authored judgment layer, not scraped pages.
Verbatim federal regulations from verified eCFR — quote the rule, not a guess.
Live CSA BASICs, risk, inspections, crashes and authority — pulled by USDOT.
Carrier data refreshed daily; metered API keys, simple x-api-key auth.

The regulations that govern your fleet — all under one roof, nothing farmed out.
Twelve products, one team and one contact — not a half-dozen vendors pointing fingers.
Everything grounded in the actual 49 CFR — accurate, defensible, never invented.
We do the work and file it. You keep driving, dispatching, and growing.
Per-job or simple monthly. No retainers, no per-seat games, no surprises.
Sample layout — real carrier results will be added here as they come in.

Use one, or let us run all of it as your outsourced safety department.
No. Each product stands on its own — start with a single DataQ challenge or a free CSA check if that's all you need. Add more whenever it makes sense, with one company behind all of it.
Yes — X3 DOT Skills. It serves verbatim 49 CFR, a 67,000-document compliance knowledge base, and live carrier safety data (CSA BASICs, risk, inspections, crashes, authority) by USDOT, updated daily. Software teams, factoring, insurers and AI tools build on it. See x3dotskills.com.
No one honestly can — FMCSA decides every challenge. What we guarantee is our work: complete, CFR-cited filings, and we tell you up front when something isn't worth fighting.
No. X3 Fleet Safety LLC is a compliance services company, not a law firm, and this site is not legal advice. For legal representation, consult a licensed transportation attorney.
