Fleet Downtime
The total time vehicles are out of service, whether planned or unplanned.
What Is Fleet Downtime?
Fleet Downtime is the total time vehicles spend out of service — in the workshop, on a defect hold, or awaiting parts — whether the cause was a scheduled service or an unplanned breakdown. Splitting downtime into planned versus unplanned shows whether a fleet's maintenance approach is proactive or reactive.
Formula
Track planned and unplanned downtime as separate figures, not just a combined total — a healthy fleet's downtime is mostly planned, not reactive.
Why Fleet Downtime Matters
Direct Driver of Availability
Every hour of downtime is an hour Fleet Availability can't count — the two metrics move together.
Reactive vs Proactive Signal
A high share of unplanned downtime relative to planned downtime is the clearest sign a maintenance program needs attention.
Revenue Impact
Downtime on revenue-generating vehicles translates directly into lost income, not just a maintenance cost line.
Typical Benchmark
💡 What's a Good Number?
The absolute downtime percentage matters less than the planned-to-unplanned ratio — a fleet with 8% total downtime that's almost entirely scheduled is healthier than one with 5% that's mostly breakdowns.
How to Improve Fleet Downtime
- Use DVIR data to catch defects before they escalate to breakdowns
- Build preventive maintenance schedules around mileage and engine hours, not just calendar dates
- Stock common parts to shorten unplanned repair time
- Review repeat-downtime vehicles for root-cause issues rather than repeated quick fixes
