FMCSA, 49 CFR 390.5 (definitions)Related terms
USDOT number
The unique identifier FMCSA assigns to a company that operates commercial vehicles in interstate commerce, used to track its safety record, inspections, and audits. Many intrastate carriers also need one under their state rules.
Apportioned plate
A single license plate issued under the IRP that lets a commercial vehicle operate in every member jurisdiction. The registrant pays each jurisdiction a share of the fee based on the miles the fleet travels there.
Base jurisdiction
The single state or province where a carrier registers under IRP and licenses under IFTA, chosen by where the fleet is based and keeps its records. The base jurisdiction collects the fees and taxes and settles them with the other member jurisdictions.
BMC-84 surety bond
The surety bond a property broker or freight forwarder files with FMCSA as its financial responsibility instrument. It guarantees payment to carriers and shippers; a broker may instead file a BMC-85 trust fund for the same amount.
