Carrier & road-transport data, explained.

Plain-English definitions of the identifiers, filings and compliance terms behind the Fraktix directory — what they mean and why they matter.

DOT number

A unique identifier the U.S. FMCSA assigns to a commercial motor carrier; it's the primary key for tracking a carrier's safety, registration and inspection record.

MC number

An FMCSA 'motor carrier' operating-authority number that shows a carrier is authorized to haul regulated freight for hire across state lines.

Operating authority

FMCSA permission that defines what kind of freight or passengers a carrier may transport for hire — common, contract or broker authority.

BIPD insurance

Bodily Injury and Property Damage liability insurance a for-hire carrier must keep on file with the FMCSA to maintain active operating authority.

Out-of-service (OOS)

An FMCSA order barring a carrier, driver or vehicle from operating until a serious safety or compliance problem is resolved.

Power units

The count of self-propelled vehicles (tractors, trucks, buses) a carrier operates — the standard measure of fleet size in FMCSA data.

MCS-150

The FMCSA registration/update form on which a carrier reports its fleet size, mileage, cargo and contact details; the source of much US census data.

Carrier vs broker

A carrier physically transports freight with its own equipment; a broker arranges transportation between shippers and carriers without hauling it.

FMCSA

The U.S. Federal Motor Carrier Safety Administration — the agency that registers and regulates commercial motor carriers and publishes the census, licensing and safety data.

DVSA

The UK's Driver & Vehicle Standards Agency, which licenses goods-vehicle operators — the source of Fraktix's UK carrier data.

SITR

France's national register of road-freight transport companies (Registre des marchandises) — the source of Fraktix's French carrier data.
