What is fleet maintenance?

Fleet maintenance is the practice of upkeeping fleet vehicles with recurring mechanical checks. A fleet maintenance manager schedules and manages fleet maintenance needs to help reduce vehicle downtime due to surprise repairs. 

 

A fleet maintenance program typically involves: 

  • Scheduling recurring maintenance events: Maintenance events vary from a basic oil change to a full heavy vehicle inspection. The most common maintenance events are oil changes and air filter replacements.
  • Overseeing routine inspections of fleet vehicles: This includes regular check-ups, tyre rotations, brake inspections and fluid level checks.
  • Deploying driver training: Drivers must understand vehicle maintenance needs, so offering training and resources is key to a successful program. 
  • Utilising fleet maintenance tools and reminders: Receiving early maintenance reminders can help you efficiently schedule necessary vehicle downtime to perform maintenance events and vehicle repairs.

The importance of fleet maintenance

Keeping your fleet in top-notch condition is one of the most important things you can do to help make your business successful. Ignoring vehicle fleet maintenance will almost always lead to costly repercussions. 

 

For example, not regularly changing a vehicle’s oil can cause immense wear and tear on the engine. The parts of the engine get significantly hotter due to friction, which could ultimately result in engine problems—leading to a costly engine replacement down the road.

 

The cost of ignoring these maintenance reminders will always be much greater than acknowledging them, so addressing these events in a timely fashion is a must when prioritising ROI vs. COI.

 

Put simply, keep your fleet operating in premium condition at all times, and you’ll have to worry less about unexpected breakdowns, costs and out-of-commission vehicles (and workers). You’ll be better equipped to maintain your schedule. More importantly, you’ll keep your customers happy and revenue flowing steadily.

 

Benefits of fleet maintenance management

Taking proactive measures to eliminate the possibility of maintenance problems down the road will invariably pay off for your fleet in uptime and dollars saved. The top benefits of implementing a fleet maintenance program are reducing costs and improving driver safety. 

Key advantages of FM

Improves regulatory compliance and inspection outcomes

A robust maintenance program helps managers meet their Chain of Responsibility (CoR) obligations under NHVR standards and the National Heavy Vehicle Inspection Manual (NHVIM).A proactive maintenance reduces the risk of major/minor defect notices during NHVR roadside checks.

 

Regular inspections are the foundation of a well-maintained fleet. They help identify minor issues before they escalate into major breakdowns and expensive repairs. By catching problems early with predictive maintenance inspections, you address them before they lead to safety hazards and delays. 

Reduces operating and repair costs 

Proactive maintenance is cheaper than reactive repairs. Regularly checking oil levels may seem like a hassle, but it can prevent the need for a full engine replacement down the road. Plus, well-maintained vehicles operate more efficiently, which helps lower fuel costs.

Aids in ESG goals

Well-maintained vehicles operate more efficiently, potentially burning less fuel and producing fewer emissions to aid in environmental, social and governance (ESG) goals. Reducing emissions benefits everyone. Whether you manage an EV fleet or not, switching to cleaner energy sources contributes to a healthier planet and can lead to cost savings.

Increases vehicle longevity

The better maintained your vehicles are, the less wear and tear they’ll experience and the longer they’ll run. When oil, filters and inspections are performed, vehicles are less likely to run into serious issues down the road — aiding in a longer vehicle life cycle

Eliminates unnecessary downtime

Healthier vehicles lead to greater productivity. Vehicle downtime directly affects a vehicle’s ability to generate revenue. Eliminating unnecessary downtime will help your company maximise the revenue stemming from your fleet.

Improves driver safety

Staying on top of repairs doesn’t just save you money — it also keeps drivers and others safer on the road. Even something as simple as faulty wiper blades can lead to a collision. A robust fleet safety program is essential for protecting drivers, vehicles and your company's reputation. Not only do drivers feel safer when operating a vehicle they know is in good condition, but it also reduces the likelihood of penalties during roadside inspections.

Vehicle maintenance challenges

It’s clear that a fleet maintenance program offers a range of benefits, but there are a few considerations to weigh. The initial implementation can be challenging without the right tools.  

 

  • Scheduling and planning: It is difficult to keep track of multiple vehicle maintenance schedules. Balancing routine inspections with unexpected repairs and aligning maintenance with driver availability can lead to scheduling conflicts and operational disruptions.
  • Managing costs: Striking a balance between maintenance and operational expenses is a constant challenge. While investing in regular inspections can reduce costly breakdowns, justifying these upfront fleet costs can be difficult.
  • Tracking maintenance history: A comprehensive maintenance history is essential for identifying trends, predicting future needs and ensuring compliance. And while maintaining accurate and accessible records for each vehicle is crucial for informed decision-making, it can be time-consuming and error-prone. 
  • Maintaining compliance: In Australia, fleet maintenance is not just a best practice; it is a legal requirement under Heavy Vehicle National Law (HVNL). Staying up-to-date with ever-changing regulations and industry standards while ensuring fleet-wide compliance is a complex and ongoing challenge. Balancing the need for vehicle uptime with regulatory requirements often necessitates careful planning and resource allocation.
  • Managing parts inventory: Finding the right balance between having necessary parts on hand and avoiding excessive inventory costs can be difficult. Insufficient stock can lead to costly downtime, while excessive inventory ties up capital.

The key to streamlining fleet maintenance is automation. Fleet maintenance software automates manual tasks, provides real-time data and offers predictive analytics in a centralised platform. That way, you can make data-driven decisions, improve operational efficiency, and reduce overall maintenance costs.

Fleet maintenance checklist

With the right inspection checklist, you can mitigate these fleet maintenance challenges. A well-structured maintenance program involves a combination of routine inspections, fluid checks and component replacements. Following a consistent checklist can prevent costly breakdowns and maintain compliance with industry regulations.

 

Follow this checklist to ensure you don’t miss important routine inspections. 

Maintenance checklist

Maintenance checks play an important role in keeping fleet vehicles operating day to day. If left unchecked, low oil and fluid levels can place strain on critical mechanical systems and lead to safety issues over time. 
 

For light vehicles, these checks are typically carried out on a monthly basis. In contrast, Australian regulations require heavy vehicles to be checked daily or before each trip.


Examples of maintenance checklist items for light vehicles can include the following:

Monthly checklist

Quarterly maintenance checklist

Similar to monthly upkeep, quarterly maintenance checks can help prevent vehicle downtime. In addition to regular oil, filter and fluid checks, it’s essential to verify that brakes and batteries are in good working order. 

QT Maintenance Checklist

Bi-annual maintenance checklist

Bi-annual maintenance focuses on more thorough inspections and part replacements to ensure your fleet operates at peak performance, such as checking for leaks and replacing filters. 

Bi-annual Checklist

Annual maintenance checklist

Yearly tune-ups are a time to reinspect critical vehicle components, like transmissions and electrical systems. At this point, vehicle parts are more likely to need repairs. 

Annual Checklist

Tips to streamline fleet maintenance management

It’s not always possible to say when each vehicle in your fleet is due for a maintenance update right off the top of your head. This is particularly true if you have a large fleet. Too many variables come into play, not to mention the other business responsibilities.

How to improve FM

 

Here are some key fleet maintenance tips to streamline productivity:

 

Customise driving rules: Driving rules, such as idle time, harsh braking and route optimisation, can be tailored to suit the specific needs of your fleet. Implementing these rules helps reduce unnecessary wear and tear, saving both time and money on repairs.

 

Set diagnostic reminders: Regular diagnostic checks are crucial to catch potential issues before they become serious problems. Automated reminders for these checks ensure that no vehicle in your fleet is overlooked, helping to keep consistent maintenance schedules.

 

Maintain compliance: Complying with regulatory requirements is essential to avoid fines and ensure the safety of your vehicles. A maintenance program helps managers meet their Chain of Responsibility (CoR) obligations. In addition, it reduces the risk of defect notices during NHVR roadside checks. 

 

Run reports regularly: Generating and analysing reports on your fleet's performance can provide valuable insights into areas needing improvement. Regular reports help you track maintenance trends, fuel usage and overall vehicle health, enabling data-driven decisions.

Automate maintenance with fleet management software

Fleet maintenance is crucial for maintaining an efficient and safe fleet, but balancing scheduling, data and tracking can be difficult. Adding a telematics solution, like the Geotab platform, to your fleet can help you stay on top of reminders and predictive maintenance to increase vehicle uptime and decrease costs.

 

With fleet management software, you can manage your entire fleet from one centralised platform to make data-driven business decisions. Streamline your fleet operations with a comprehensive, integrated solution.
