Spare Taxis Strategy to Cut Fleet Downtime
Downtime costs. Drivers waiting. Customers left frustrated. If you manage a taxi fleet, you already know how one breakdown can ripple through your operation. This guide walks you through a practical, no-nonsense approach to building and running an effective spare taxis programme that keeps vehicles moving and fares coming in. Expect clear formulas, operational workflows you can adopt, and the tech that makes it all simple.
Why Spare Taxis Matter
Cost of Downtime — Direct and Indirect Impacts
Lost revenue from a single taxi off the road is the obvious hit. But the indirect costs can be worse: cancelled jobs, driver idle time, lost customer trust and negative reviews. When you factor in repeat business and brand reputation, downtime becomes a strategic issue. A well-managed pool of spare taxis shrinks the time between fault and replacement, reducing both immediate revenue loss and long-term churn.
Key Availability Metrics
To manage spares effectively you need the right metrics. Track uptime, mean time to repair (MTTR), time-to-replace and utilisation of spares. Aim to keep MTTR low and spare utilisation balanced; too low and you are wasting assets, too high and you risk unserved trips. Use simple dashboards to spot patterns—vehicle models with higher failure rates, peak hours when replacements are most needed, and drivers who repeatedly submit vehicles for repair.
Designing a Spare Fleet Strategy
Calculating Your Spare Ratio
Start with a baseline formula: Spare Ratio = (Number of Spares / Active Fleet) x 100. Adjust for failure rates, service level targets and peak demand. For taxis, a common approach is to model downtime probability over a month and size spares to achieve a maximum acceptable refused-trip rate. Run scenarios: what if a popular model has a 4% downtime rate? How many spares do you need to keep refusals under your threshold? A small calculation here saves a lot of stress later.
Selecting Vehicle Types & Condition
Match spares to the jobs they will cover. If you run mixed vehicle categories, keep a like-for-like approach where possible. Sometimes a high-quality used car makes a better spare than a brand-new vehicle that sits idle. Consider branding, accessibility features, and fuel types. The goal is to minimise disruption for both driver and passenger when a swap happens.
Allocation Models & Location Planning
Decide between dedicated spares assigned to depots and pooled spares that float across zones. For dense urban operations, hubs near busy ranks reduce response times. For suburban routes, a distributed model may beat centralisation. Use historical breakdown locations and telematics data to map ideal spare locations and reposition spares before peak periods.
Operational Processes for Deploying Spares
Dispatch & Handover Workflow
Clear, repeatable workflows prevent mistakes. Create a short handover checklist for drivers that covers vehicle condition, fuel, insurance papers and fare meters. Use a digital sign-off to timestamp swaps. The quicker and more consistent the handover, the less time the driver spends off the road. A standard checklist also protects you against disputes later.
Communication & Coordination Protocols
Standard scripts for dispatchers and templated SMS or app messages to customers keep everyone informed. When passengers are impacted, timely communication reduces complaints and increases forgiveness. Your dispatch system should automatically flag when a spare is used so drivers, mechanics and operations all see the status in real time.
Integration with Repair & Return-to-Service
Log every failed vehicle into a repair pipeline so mechanics know priority and parts history. When a vehicle returns from the workshop, run a short readiness inspection before it rejoins the pool. Use a simple status workflow: Reported → Repaired → Quality Check → Back to Pool. This prevents partially fixed cars returning to service and causing repeat downtime.
Technology & Tools to Support Spare Management
Fleet Management Software Capabilities
Look for software that supports spare reservations, instant allocation and utilisation dashboards. A good system will show which spares are available, where they are located and which trips they can cover. Integrate with your central dispatch so the decision to deploy a spare is data-driven. If you want to see how such systems work in practice, book a demo with Traknova and see allocation in action.
Telematics & Health Monitoring
Telematics gives you early warning signs. Engine fault codes, battery health and fuel alerts help you pre-empt failures and position spare taxis where they will be needed. Predictive alerts cut emergency swaps and keep MTTR down. Adding telematics to your fleet is a direct way to lower downtime and repair costs. Consider combining telematics with dash cams for additional context on incidents; more on that in our piece about Dash Cameras: 9 Benefits Every Fleet Manager Needs.
Driver & Field Apps
Mobile apps for drivers speed the handover process. Use quick digital inspections, photo uploads and auto-generated replacement requests. Drivers should be able to request a spare and receive an ETA, minimizing idle time. Make sure apps sync with your central system so operations know when a spare has been deployed and when the failed vehicle is headed to repair.

Policies, Maintenance & Cost Control
Preventive Maintenance for Spares
Spare vehicles still need attention. Schedule lower-frequency checks so spares are ready without wasted servicing. Rotate mileage between spares and active cars to prevent long-term storage issues. Keep a minimum fuel level and a rolling checklist so a spare is always ready within minutes. Good preventive care reduces the chance a spare will itself become a source of downtime.
Insurance, Compliance & Risk Management
Confirm that spares are covered under your existing policy and that paperwork travels with the car. For taxis you should ensure the vehicle meets all regulatory and local licensing conditions before deployment. Keep a digital folder attached to each vehicle record so any auditor or inspector can see proof of cover and compliance instantly.
KPIs, Budgeting & Continuous Improvement
Track spare utilisation, cost per spare, MTTR and refused-trip rates. Use monthly reviews to adjust spare ratios and reallocate budget where it delivers the biggest uptime gains. Continuous improvement might mean shifting from dedicated spares to a pooled model, or investing in better telematics for predictive maintenance.
Conclusion
Spare taxis are not just an insurance policy; they are a strategic lever to protect revenue and reputation. With the right ratio, clear processes, and connected technology like telematics and driver apps, you can turn breakdowns from panic events into routine, low-impact operations. Focus on metrics, standardise handovers and make sure spares are integrated into your maintenance lifecycle. The result is happier drivers, fewer lost fares and a fleet that performs consistently.
FAQs
How many spare taxis should I keep?
It depends on your fleet size, failure rate and service level target. Start with the Spare Ratio formula and model scenarios. For many taxi fleets a small, well-positioned pool of spares provides better coverage than a single backup per depot.
Should spares be brand new?
Not necessarily. High-quality used vehicles that match operational needs often give the best balance between readiness and cost. Focus on reliability, compliance and quick reconditioning rather than age alone.
Can technology really reduce downtime?
Absolutely. Telematics, automated dispatch and driver apps cut reaction times and help you pre-position spares. These tools reduce MTTR and prevent many breakdowns by enabling predictive maintenance.
How do I manage insurance for replacement vehicles?
Work with your insurer to ensure spares are listed and covered for taxi operations. Keep digital proof of cover with each vehicle file and standardise documentation so deployment is seamless and compliant.
