AOBRD (Legacy)

Definition

AOBRD - Automatic On-Board Recording Device - is the legacy electronic logging technology that pre-dated the modern ELD mandate. AOBRDs were authorized under the old §395.15 and could record HOS data with looser technical requirements than today's ELDs (no engine-data feed mandate, fewer event types). The ELD Mandate phased AOBRDs out completely on December 16, 2019; carriers operating AOBRDs after that date were considered non-compliant unless they qualified for a specific exemption. The term still appears in regulatory history and on older fleet-management contracts. Modern systems (Samsara, KeepTruckin, Geotab, etc.) all ship as registered ELDs with full §395.8 compliance.
