What Is Fleet Maintenance? Benefits & Best Practices

If a vehicle breaks down, it’s a missed delivery, a delayed project, a frustrated customer, and a team waiting. And that wait gets expensive. 

Breakdowns cost businesses $500 to $2,000 per day per vehicle. That number includes repairs, lost revenue, wasted labor, and damage to customer relationships. On top of that, indirect costs like towing, rescheduling, and compliance issues can add another 35–45% to every maintenance bill.

Fleet maintenance helps you avoid that spiral. With the right system in place, you can catch issues early, stay compliant, and keep your team and assets moving.

In this guide, we break down what fleet maintenance involves, why it’s critical for growing operations, and how to set up a strategy that cuts costs and builds efficiency.

What Is Fleet Maintenance?

Fleet maintenance is the process of keeping a company’s vehicles and equipment in safe, reliable working condition through regular inspections, routine service, and timely repairs. It includes everything required to prevent breakdowns, reduce downtime, and ensure compliance with safety and regulatory standards.

This can involve preventive maintenance (like oil changes and tire rotations), reactive maintenance (fixing unexpected issues), and inspections required by law, such as daily Driver Vehicle Inspection Reports (DVIRs).

For growing fleets, maintenance also includes tracking service history, managing parts inventory, and using software to schedule work, assign tasks, and monitor vehicle performance across locations.

Why Fleet Maintenance Matters for Your Business

Fleet maintenance helps protect your bottom line, your reputation, and your team. Here’s why it matters:

Lower Costs, Higher Efficiency

Fleet maintenance directly impacts your bottom line. Preventive service costs less than emergency repairs, and it helps you catch issues before they lead to engine failures, roadside breakdowns, or extended downtime.

For example, scheduling regular oil changes and tire rotations keeps your fleet running efficiently and prevents wear that can take entire vehicles out of commission. Skipping those steps to “save time” often leads to higher fuel costs, more breakdowns, and a repair bill that could’ve been avoided entirely.

A fleet maintenance software like Whip Around helps build that process. It links inspections with automated service schedules and tracks every repair in one place. You can set service intervals based on mileage, hours run, or time in service. Once a vehicle hits the threshold, the system automatically notifies your team. Plus, you can assign the repair to your in-house mechanic, an outside vendor, or a third-party shop, depending on what makes sense for that asset.

Safety and Compliance

Fleet maintenance is a legal requirement under the U.S. Department of Transportation (DOT), enforced by the Federal Motor Carrier Safety Administration (FMCSA). The key regulation is 49 CFR Part 396, which covers inspection, repair, and maintenance standards for commercial vehicles.

To stay compliant, carriers must:

• Complete daily Driver Vehicle Inspection Reports (DVIRs)
• Perform annual inspections certified by a qualified mechanic
• Keep maintenance and inspection records for at least 12 months (and for 6 months after a vehicle leaves the fleet)
• Resolve any safety-related defects before a vehicle is operated again

Missing documentation, skipped inspections, or unresolved defects can lead to fines, out-of-service violations, or failed audits.

Longer Asset Life and Better Resale Value

Vehicles are expensive to replace. A solid maintenance routine extends the lifespan of your fleet and helps you get more value when it’s time to sell.

Prospective buyers want records. If you can show detailed logs of inspections, repairs, and regular service, your vehicles are more attractive and command a higher resale price. That’s money back into your business instead of left on the table.

Types of Fleet Maintenance Strategies

Not all maintenance is created equal, and not every fleet needs the same approach. The right strategy depends on the size of your fleet, the type of assets you manage, how often they’re used, and how much downtime you can afford.

Preventive vs. Predictive Maintenance

Both preventive and predictive maintenance aim to reduce downtime and avoid costly repairs but they take different paths to get there.

Preventive Maintenance

This is the most common strategy for fleet-based businesses. Preventive maintenance follows a set schedule. You perform service tasks at regular intervals based on mileage, engine hours, or calendar time—regardless of the vehicle’s current condition.

Typical examples include:

• Oil changes every 5,000 miles
• Brake checks every 90 days
• Tire rotations every 10,000 miles

The goal is to catch wear and tear before it causes breakdowns. It’s reliable, easy to standardize, and helps extend asset life.

Predictive Maintenance

Predictive maintenance goes beyond fixed service intervals by using real-time data from sensors, telematics, and diagnostics to anticipate when a vehicle actually needs service. 

For example:

• Replacing brake pads based on wear patterns, not mileage
• Servicing engines when vibration or temperature data signals a performance issue

This strategy is often most impactful for larger, highly connected fleets, but that’s changing. Advances in telematics, like affordable sensor technology, standardized vehicle data APIs, and AI-powered analytics, are making predictive tools increasingly accessible to smaller fleets as well. Even without a dedicated data team, operators can start layering predictive elements into their maintenance process as tools become more user-friendly and cost-effective.

Reactive Maintenance: When It’s Inevitable

Reactive maintenance is any repair or service that happens after a failure. A flat tire. A dead battery. An overheating engine. These are unplanned events that require immediate attention to get the vehicle back on the road.

While reactive maintenance is usually more expensive and disruptive, it’s not always avoidable. Even well-maintained vehicles can hit unexpected issues—especially in demanding environments or with aging equipment.

Here’s when reactive maintenance is inevitable:

• A driver discovers a new defect mid-route
• A component fails between scheduled service intervals
• An accident causes sudden mechanical damage
• A third-party asset returns with undisclosed issues

Scheduled vs. Unscheduled Maintenance

Every maintenance task falls into one of two categories: scheduled or unscheduled. 

Scheduled Maintenance

Scheduled maintenance includes any service planned in advance. This typically follows a set interval based on mileage, engine hours, calendar time, or manufacturer recommendations.

Examples:

• Oil and filter changes every 5,000 miles
• Brake inspections every 90 days
• Seasonal tire swaps
• Annual DOT inspections

Scheduled maintenance gives you control. You can plan around it, assign tasks in advance, order parts ahead of time, and make sure vehicles are serviced without disrupting your operation. Most fleets aim to keep as much maintenance as possible in this category.

Unscheduled Maintenance

Unscheduled maintenance happens when something breaks unexpectedly. It could be the result of skipped inspections, missed preventive service, or just regular wear catching up faster than expected.

Examples:

• Sudden engine failure
• Brake system malfunction
• Flat tire from road debris
• Broken liftgate during loading

Unscheduled repairs are harder to plan for, cost more, and often lead to unplanned downtime. That’s why tracking defect trends, logging service history, and staying on top of inspections is critical. These steps help shift more of your maintenance into the “scheduled” column.

Seasonal and Environmental Considerations

Where and when your fleet operates has a direct impact on how you manage maintenance.

Cold climates mean more stress on batteries, starters, and diesel engines. Frozen air lines, low tire pressure, and thickened fluids are common cold-weather issues that require seasonal checks and winterization routines.

Hot weather brings its own challenges—overheating engines, worn belts, tire blowouts, and higher strain on AC systems. Summer driving also means longer routes, higher payloads, and increased wear on brakes and suspension systems.

Dusty, muddy, or off-road environments can clog filters faster and cause more undercarriage damage, especially in construction, agriculture, or unpaved delivery zones.

Smart fleet managers build seasonal service checklists into their maintenance plans. That might include:

• Battery and electrical system checks before winter
• Cooling system flushes before peak summer heat
• Filter replacements and undercarriage inspections after dusty seasons
• Tire inspections tied to temperature swings

Technology-Driven Maintenance 

Fleet maintenance requires more than a garage and a clipboard. You need real-time data from your vehicles, automated schedules, and clear communication between drivers, mechanics, and managers.

Platforms like Whip Around give you a single system that connects inspections, service scheduling, work orders, and inventory management—while also integrating with the tools you already use.

Here’s what that looks like:

• Digital inspections (eDVIRs): Drivers complete mobile inspections with required steps, photo capture, and defect logging
• Automated scheduling: Set service intervals by mileage, hours, or time. Get alerted before maintenance is overdue
• Work order management: Turn defects into work orders instantly, assign them to in-house or external teams, and track repair status in real time.
• Inventory tracking: Manage parts across work orders and get alerts when stock runs low
• Service history: Access a full digital record of every inspection, repair, and status change ready for audits or resale.

Here is an example of how the work orders look like inside Whip Around:

And it’s not a standalone system.

Whip Around integrates with leading telematics providers like Geotab, Samsara, Motive (formerly KeepTruckin), Verizon Connect, Trimble, GPS Insight, and LionEight, among others. These integrations bring in odometer readings, fault codes (DTCs), vehicle location, and sensor data, helping you automate service schedules, respond faster to issues, and make smarter maintenance decisions. 

For communication, it connects with Slack and Microsoft Teams to help drivers, mechanics, and managers stay in sync without jumping between apps.

Whip Around also integrates with WEX fuel cards, giving you real-time insight into fuel usage and spend—making it easier to spot inefficiencies and manage costs across your fleet.

Common Challenges in Fleet Maintenance

Here are some of the most common issues that get in the way of efficient, cost-effective maintenance:

Fragmented Systems and Manual Tracking

Many fleets still rely on spreadsheets, whiteboards, email threads, or paper inspection logs to track vehicle status and service records. These systems work until they don’t.

When maintenance data lives in different places, it’s easy to miss service intervals, lose track of defects, or double-book a mechanic. There’s no real-time visibility, no audit trail, and no way to spot patterns across the fleet.

Whip Around users have a clear view of their entire fleet in a centralized dashboard, from which they can expand on each asset’s individual status.

Missed Maintenance Due to Poor Scheduling

Preventive maintenance only works if it happens on time. But when scheduling is handled manually, it’s easy for tasks to fall through the cracks especially when vehicles rotate between job sites or shift schedules.

If oil changes or brake checks are delayed, wear and tear builds up. What could’ve been a 30-minute service job becomes a major repair. Multiply that across a fleet, and you’re looking at thousands in avoidable costs.

Driver Compliance and Reporting Gaps

Drivers are your first line of defense against breakdowns, but inspection compliance is often inconsistent. Paper DVIRs get rushed, lost, or skipped altogether. Defects are reported with vague notes or no detail, which slows down repairs and frustrates mechanics.

Budgeting for Unplanned Repairs

Reactive maintenance is unpredictable. A surprise breakdown throws off your schedule and your budget. You pay more for emergency parts, outside vendors, and overtime labor. And while you’re dealing with the repair, that vehicle is sitting idle, costing even more.

How to Choose the Right Fleet Maintenance Solution

You need to find a tool that fits how your fleet operates. Here’s a practical way to approach the decision:

• Assess your fleet size and complexity: Are you managing 10 trucks or 100 assets across multiple job sites? Do you have in-house mechanics or outsource all your repairs? The right solution should match your setup. 
• Evaluate your current maintenance processes: Where are things falling apart today? Are drivers skipping inspections? Are work orders getting lost in email? Start by identifying what’s broken in your current process; then look for a platform that addresses those specific gaps.
• Define your budget: Don’t just think about upfront costs. Consider the long-term value: fewer breakdowns, less downtime, and better visibility can all save money over time. The cheapest tool may not give you what you need—or cost you more in the long run.
• Consider integration requirements: If you’re using telematics, GPS, fuel cards, or inventory systems, make sure your maintenance platform can integrate with them. Connected data means fewer manual updates and better decisions based on what’s actually happening in the field.
