Fleet Availability
The percentage of scheduled time a vehicle is roadworthy and ready for dispatch.
What Is Fleet Availability?
Fleet Availability measures the percentage of scheduled operating time that a vehicle is roadworthy and ready to be dispatched — not in the workshop, not on a defect hold, and not awaiting parts. It caps what utilisation can ever reach: a vehicle can't be used if it isn't available.
Formula
Include both planned downtime (scheduled services) and unplanned downtime (breakdowns, defect holds) in the calculation for an honest figure.
Why Fleet Availability Matters
Ceiling on Utilisation
Low availability limits how much productive use a vehicle can generate, regardless of demand.
Maintenance Health Indicator
A declining availability trend usually points to rising unplanned downtime, not planned servicing.
Capacity Planning
Fleet managers need real availability, not fleet size on paper, to plan routes and commitments accurately.
Typical Benchmark
💡 What's a Good Number?
High-performing fleets often target availability above 90%, though the right number depends heavily on vehicle age, type, and operating conditions — track the trend rather than chasing a fixed figure.
How to Improve Fleet Availability
- Strengthen preventive maintenance scheduling to reduce unplanned downtime
- Keep critical parts in stock for the most common defect categories
- Reduce Mean Time to Repair (MTTR) so downtime events are shorter
- Use DVIR-driven defect detection to catch issues before they cause a breakdown
