Why operators use it
We use PRIME-01 so that when transport work is shared with a customer, principal, contractor, subcontractor, labour-hire provider or site, everyone understands the actual work, control boundaries, safe conditions, evidence, communication and escalation arrangements before the work creates public risk.
Many safety failures occur at the handover between businesses: an unsafe time slot, unclear booking condition, unavailable site information, unsuitable vehicle/load/task, unverified driver/workforce arrangement, evidence that has expired, a changed service, an incentive that pressures a driver, or a hazard that is known to one party but not another. PRIME-01 makes those interfaces visible and actionable.
