Nobody buys a CARB tracker — they buy “don’t send a truck somewhere it can’t legally operate.” Tell X3 the truck and the route and it answers instantly: Allowed, Restricted, or Not compliant — with the risk and the docs you need.
Tell X3 the truck and where it’s going and it returns a clear dispatch verdict — Allowed, Restricted, or Not compliant — with the reason and required actions. Here’s a sample:
Sample carrier · your real fleet fills the same dashboard

Dispatch asks “can Truck 12 take this load into California?” and someone Googles it, calls compliance, or dispatches anyway and eats a fine. X3 answers instantly — and plans which trucks to retire before they become restricted assets.
✅ Allowed, ⚠ Restrictions, or ❌ Not compliant — with the reason, required docs, and an alternative truck if this one can’t go.
CARB, EPA, state and local rules change constantly. The regulatory agent updates daily so your dispatch answers are never stale.
See which trucks create the most access risk, which to replace first, and a Fleet Access Score for the whole fleet — an executive view of where you can and can’t run.

X3 knows the emissions and access rules that decide where a truck can legally run — federal, state, regional and municipal — and keeps them current.
A cause-and-effect intelligence system: violation intelligence flows into Fleet access rules, behavior mapping and inspection-risk, then into prevention, corrective action, forecasting and an executive brief. Grounded in the X3 DOT Skills corpus and verified SMS methodology.

We pull your live FMCSA record through CarrierOK — every BASIC percentile, inspection, violation, crash and insurance filing. No spreadsheets, no manual entry.
Every morning we re-pull and diff your record, so you know exactly what changed overnight — before FMCSA or your insurer does.
Prioritized fixes ranked by business impact, the exact inspections worth a DataQ challenge, coaching plans, and an insurer-ready packet.
Never dispatch a truck somewhere it can’t legally operate. Cancel anytime.
No. It’s a fleet-access platform. Nobody wants a CARB tracker — they want a dispatch answer: can this truck legally run this route, and if not, which truck can. X3 gives you the verdict and the plan.
CARB (Clean Truck Check / Advanced Clean Fleets), EPA, and state/regional/municipal access rules and low-emission zones — updated daily. Guidance to verify with each agency.
Yes — one login across the X3 empire. Clean Truck feeds Permits (weight-mile), HazMat (route restrictions), Audit (vehicle docs) and Insurability (vehicle age + compliance).
Tell X3 the truck and the route and get a clear Allowed / Restricted / Not compliant verdict — before you dispatch.
