Each block is computed in its own time zone: authority from the business state of the registration dataset, biennial_update from the physical state of the Company Census File; as_of_differs_between_blocks=true shows that the two dates differ, and neither is preferred. deadlines lists the upcoming dated deadlines of both blocks (involuntary suspension notices, insurance cancellations that are not replacements, next biennial update), sorted by date; it is a list of dates, not an assessment of the carrier. For the biennial update, the rule stays in force and the FMCSA says it suspends deactivation (see enforcement); both are stated. Operating authority: The FMCSA's Registration Alerts page (updated October 12, 2026) names its Licensing and Insurance (L&I) system as the authoritative record of operating authority; a Federal Register notice of April 29, 2026 (2026-08334) announces that L&I will be retired in favor of Motus, without setting a date. Check the FMCSA's official record before acting. No insurance could be filed from May 14 to 19, 2026, and some effective dates were backdated when Motus opened. Motus corrects wrongly issued suspensions in bulk, sometimes days later. found=false means no operating authority is on the register for this USDOT number; it does not mean the carrier is not authorized (a private carrier needs none). The law sets no time limit between an insurance cancellation, a suspension and a revocation: no such date is computed, only dates the FMCSA publishes are returned. The suspension notice dataset carries no revocation and no reason (insurance or process agent), keeps a notice even after it was cured (see insurance_filing_received_since_served), and only goes back to May 18, 2026; not every suspension is preceded by a published notice. registry_vs_history compares the registry status with the latest history event; the registry does not always follow voluntary suspensions, and both are returned without arbitration. newer_policy_on_file flags another policy of the same coverage on file with a later effective date (newer_policy_effective_date); it does not guarantee continuous coverage and may not be in effect yet. No coverage gap is computed. Insurance cancellations cover the last 60 days and ahead; a cancellation without a readable date is not returned. Coverage amounts are returned as the source delivers them: the data dictionary says thousands of dollars, the values read are in dollars. first_seen_on is the date this service first saw the row in its daily harvest (null when unknown). MCS-150: Exemption: a carrier registering its vehicles in a PRISM State and filing with that State is exempt (49 CFR 390.19T(i)); the FMCSA file does not show it. overdue=null means the rule or the data does not settle the case. For a missed deadline, deactivation_exposure is null: the rule still provides for deactivation, and the FMCSA notice (see enforcement) suspends it explicitly for deadlines due on or after 2026-06-01 and, in wording with no date limit, for entities that have not filed; for earlier deadlines the notice settles neither exposure nor its absence. File anyway.
