Downtime is the period a unit cannot operate: shop, incident, missing driver, or hold. Measure it separately from appointment/dock time (detention) and freeze what counts as “out of service.”

What it is (usable answer)
Downtime is the period a unit cannot operate: shop, incident, missing driver, or hold. Measure it separately from appointment/dock time (detention) and freeze what counts as “out of service.”
Decision matrix
Use the table to decide what to instrument first and what not to mix in the same KPI.
Shop
Example: Corrective / long preventive
Owner: Maintenance
KPI: Hours out
Driver
Example: Absence / HOS exhausted
Owner: Traffic / HR
KPI: Lost trips
Incident
Example: Unit held
Owner: Safety / insurance
KPI: Days to release
Admin
Example: Papers / inspection
Owner: Compliance
KPI: Days blocked
How it applies on Mexico–U.S. lanes
On corridors like Monterrey–Laredo or Bajío–border, GPS jamming, DC appointments, and fiscal trip evidence condition any board. Bind the signal to the trip file (POD, CFDI/Carta Porte when applicable) before celebrating a %.

OCL and the trip file
OCL administers own fleet and workshops. It binds evidence to the trip, agents operate portals, and your team enters on exceptions. It can stamp invoice and Carta Porte when applicable. Pilot 6–8 weeks; 5–7% pattern when auditing 100% of third-party freight.
Key takeaways5 points
- Hours or days a unit cannot generate trips. Separate it from dock detention and define causes (shop, driver, incident).
- Freeze definition, units, and owner in writing before fighting the board.
- Bind it to trip/unit ID and evidence (GPS, POD, shop).
- Calibrate 2026 ranges to your fleet — do not copy viral targets.
- OCL administers own fleet and workshops: trip file + exceptions; dynamic last-mile routing; your team decides.
Does your control have an owner — or only a chart?

It is a pillar of the fleet management hub: without this piece, the eight-pillar board is incomplete.
Do not use a viral number as a blind target. 2026 telematics cases publish ranges (fuel, maintenance, utilization) — calibrate to your baseline and corridor.
OCL is an autonomous TMS that administers own fleet and workshops: it binds evidence to the trip file, operates GPS portals when needed, and escalates exceptions. Pilot 6–8 weeks; 5–7% pattern when auditing 100% of freight. It can stamp invoice and Carta Porte when applicable.
Freeze definition and owner, bind trip/unit ID, measure 4–6 weeks vs baseline, then scale hardware or rules.
