What Is an Out-of-Service Rate and What Number Should Your Fleet Be Aiming For in 2026?

Key Takeaways

• An out-of-service rate is the share of roadside inspections that result in a vehicle or driver being placed out of service, calculated as OOS inspections divided by total inspections.
• CVSA’s most recently completed International Roadcheck, conducted in 2025, recorded a vehicle out-of-service rate of 18.1% and a driver out-of-service rate of 5.9% across 56,178 inspections, according to CVSA’s published Roadcheck results.
• The national vehicle out-of-service rate has moved between roughly 16.5% and 23% over the past eight years of Roadcheck events, according to CVSA’s year-by-year results.
• CVSA’s 2026 International Roadcheck ran from May 12 to 14, with ELD tampering and cargo securement named as the two focus areas for the year.
• A vehicle that passes a Level I or Level V inspection without a critical violation earns a CVSA decal, valid for up to three months, which generally exempts it from reinspection during that window.
• Out-of-service violations carry higher severity weight in FMCSA’s Safety Measurement System than non-OOS findings, meaning a single OOS event can affect your carrier profile more than a routine citation.
• Falsification of records of duty status was the second most-cited driver violation across all FMCSA inspections, with 58,382 violations recorded in 2024, according to CVSA annual data.

Introduction

A roadside inspection either ends with your truck back on the road in a few minutes or with a driver sitting at a weigh station waiting on a repair, a tow, or a call to dispatch. The difference between those two outcomes, repeated across every inspection your fleet goes through in a year, is what shows up as your out-of-service rate. It is one of the few numbers that tells you, without any guesswork, how your fleet actually performs when an inspector is standing at the door of the cab.

Most fleet owners know the phrase out-of-service order from the moment it happens to them. Fewer track it as a rate they can measure and improve over time. That gap matters, because your out-of-service rate is not just a compliance statistic. It follows your carrier into FMCSA’s Safety Measurement System, and it shapes how insurance underwriters price your risk long before a bad inspection ever becomes a pattern.

Here is what the rate actually means, how it is calculated, and where the national benchmark has landed over the past several Roadcheck cycles. You will also see a realistic target for a small or mid-sized fleet in 2026, what tends to drive the number up, and how it connects to your CSA score and your insurance costs.

What Is an Out-of-Service Rate?

An out-of-service rate is the percentage of roadside inspections that result in a vehicle, a driver, or both being pulled from service until a violation is corrected. It is a measurement of outcomes, not just a count of violations, since a truck can rack up several citations at an inspection without ever being placed out of service.

The rate applies at two levels. CVSA publishes a national rate each year based on its International Roadcheck event, which gives the industry a benchmark to compare against. Your own fleet also has its own rate, built from every roadside inspection your trucks go through across the year, not just the ones that happen during a named enforcement event. That second number is the one that actually reflects your operation.

A vehicle out-of-service violation typically means a mechanical or documentation problem serious enough that the vehicle cannot legally continue, such as a critical brake defect or a missing record of duty status. A driver out-of-service violation usually means the driver cannot legally continue operating, such as exceeding an hours-of-service limit or lacking a valid medical certificate. Both count toward the rate separately, and both carry consequences for your carrier’s compliance profile.

How Is Your Fleet’s Out-of-Service Rate Calculated?

Your fleet’s out-of-service rate is the number of inspections that resulted in an out-of-service order divided by the total number of inspections your trucks and drivers went through over a given period. If your fleet had 40 inspections in a year and 4 resulted in an out-of-service order, your rate is 10%.

This is a lagging metric, meaning it only reflects inspections that already happened. That is exactly why tracking it matters. A fleet that reviews its inspection history regularly can spot a pattern, such as the same defect showing up across multiple trucks or the same driver getting flagged more than once, before that pattern turns into a larger compliance problem.

Your inspection history is available through FMCSA’s public systems and through your own carrier records. A registered ELD platform makes this easier to track because your logs, your DVIR history, and your inspection outcomes live in one place instead of being scattered across paper files and separate systems. We provide a management portal that keeps your compliance records organized in one view, which is the starting point for actually calculating and tracking this number over time. You can see how our ELD platform and hardware supports that kind of ongoing recordkeeping.

What Was the National Out-of-Service Rate in the Most Recent Completed Roadcheck?

The most recently completed CVSA International Roadcheck, held in 2025, recorded a vehicle out-of-service rate of 18.1% and a driver out-of-service rate of 5.9% across 56,178 inspections conducted in the United States, Canada, and Mexico.

That means roughly one in five vehicles inspected during the three-day event was pulled from service, and about one in seventeen drivers. CVSA runs Roadcheck as a concentrated 72-hour inspection blitz, so its results tend to run somewhat higher than the average rate a typical carrier sees across a full year of routine inspections, since enforcement staffing and inspection intensity are elevated during the event.

CVSA’s 2026 International Roadcheck ran May 12 through 14, with ELD tampering, falsification, or manipulation named as the driver focus area and cargo securement named as the vehicle focus area for the year. Full aggregate results from the 2026 event are compiled and published by CVSA later in the year, so the 18.1% and 5.9% figures from 2025 remain the most recent complete national benchmark available as of this writing. We recommend checking CVSA’s International Roadcheck results directly once the 2026 figures are released.

What Out-of-Service Rate Should Your Fleet Be Aiming For in 2026?

Your fleet should be aiming for an out-of-service rate meaningfully below the national benchmark, which sat at 18.1% for vehicles and 5.9% for drivers in the most recent completed Roadcheck year. For a small fleet running organized maintenance and driver compliance practices, a realistic working target is a single-digit percentage or lower across a full year of inspections.

The national Roadcheck number is a useful reference point, but it is not the number to be satisfied with. It reflects the industry as a whole, including carriers with no organized inspection or maintenance program at all. A fleet running a registered ELD and a documented DVIR process has the tools to sit well below that average rather than near it.

One practical marker to track alongside your rate is how often your trucks earn a CVSA decal, issued when a vehicle passes a Level I or Level V inspection without a critical violation. A decal is valid for up to three months and generally exempts the vehicle from reinspection during that window, which is a useful proxy for whether your inspection outcomes are trending in the right direction.

If your current rate is running at or above the national average, that is a signal to look at where the failures are concentrated, whether that is a specific truck, a specific driver, or a specific violation category, rather than treating every inspection as an isolated event.

What Drives Your Fleet’s Out-of-Service Rate Up?

The two biggest drivers of a fleet’s out-of-service rate are unresolved vehicle defects and gaps in driver compliance documentation, and both are largely preventable with consistent daily habits rather than reactive fixes.

On the vehicle side, brake system issues have led national out-of-service findings in nearly every recent Roadcheck cycle, regardless of what CVSA’s named focus area was for that year. A defect that a driver notes on a DVIR but that never gets repaired or documented is the most common way a known problem turns into a roadside out-of-service order weeks later. Connecting your DVIR process directly to your maintenance workflow closes that gap, since a defect logged by the driver creates a repair record immediately instead of sitting in a folder. Our article on how ELD and DVIR data work together covers this connection in more detail.

On the driver side, hours-of-service violations and records of duty status issues are consistently among the top driver out-of-service categories. Falsification of records of duty status was the second most-cited driver violation across all FMCSA inspections, with 58,382 violations recorded in 2024, according to CVSA annual data. An ELD that records driving time automatically from the engine removes most of the manual error and falsification risk that paper logs and manually maintained records carry.

For 2026 specifically, CVSA’s focus on ELD tampering and cargo securement means inspectors are directing extra attention to those two categories, though the full 37-step Level I inspection process still applies regardless of the named focus area.

How Does Your Out-of-Service Rate Affect Your CSA Score and Insurance Costs?

Out-of-service violations carry a higher severity weight in FMCSA’s Safety Measurement System than routine citations, which means a rising out-of-service rate has an outsized effect on your carrier’s CSA profile compared to minor paperwork issues.

FMCSA’s Safety Measurement System tracks violations across a rolling window and weighs more recent and more severe findings more heavily. A pattern of out-of-service events, even spread across different trucks or different drivers, moves your carrier’s percentile ranking faster than isolated minor citations would. Once a carrier crosses into an intervention threshold in a given BASIC category, that can trigger a compliance review, which carries its own time and financial cost separate from the original violations. Our article on how ELD violations affect your compliance record walks through how that scoring works in practice.

Insurance underwriters also review a carrier’s inspection and out-of-service history when setting premiums. A clean inspection record with a low out-of-service rate is a materially better risk profile than a record showing repeated OOS events, even if the total number of citations looks similar on paper. That connection is not always obvious to a fleet owner focused only on avoiding the immediate fine, but it shows up clearly at renewal time.

How Has the National Out-of-Service Rate Changed Over Time?

The table below shows CVSA’s published vehicle and driver out-of-service rates from each completed International Roadcheck over the past several years, giving your fleet a multi-year reference point rather than a single snapshot.

These figures come from CVSA’s International Roadcheck results, which the organization publishes after each year’s event.

The national vehicle rate has moved within a fairly narrow band, roughly 16.5% to 23%, across every year in this table. There is no clear year-over-year downward trend, which is a useful reminder that the industry average is not steadily improving on its own. A fleet aiming to stay meaningfully below this range needs its own process, not general industry momentum.

What Questions Should You Ask to Lower Your Fleet’s Out-of-Service Rate?

Do we currently know our fleet’s out-of-service rate?

If you cannot answer this with a number, start by pulling your inspection history and calculating it. Most fleet owners can name their last citation but cannot say what percentage of their inspections actually ended in an out-of-service order. You cannot improve a metric you are not tracking.

Are our DVIR defects actually getting repaired and documented?

A defect noted on a form that never reaches the shop is the most common gap between a known issue and a roadside out-of-service order. Pull a sample of recent DVIRs and check whether each reported defect has a matching repair record with a date and a signature. If that trail is missing or inconsistent, the paperwork is not doing its job even if the driver is filling it out correctly.

Is our ELD device currently on the FMCSA-registered list?

A device that was compliant at purchase can be removed later, and running a revoked device creates an automatic out-of-service risk unrelated to your actual driving or maintenance practices. Check the registered list against every device in your fleet, not just the ones you remember buying most recently. A single overlooked device can undo months of otherwise clean inspection history.

Do our drivers understand what triggers a driver-side out-of-service order?

Hours-of-service limits, missing medical certificates, and record of duty status gaps are common and largely preventable with basic awareness. A short refresher covering these specific triggers, rather than a general compliance overview, tends to close this gap faster. Ask your drivers directly whether they know what a driver-side out-of-service order actually looks like before assuming they do.

Are we tracking which trucks or drivers are generating repeat violations?

A pattern concentrated in one vehicle or one driver points to a specific fix, such as a mechanical issue that keeps recurring or a driver who needs targeted coaching, rather than a fleet-wide problem. Without tracking this by truck and by driver, a repeat issue can look like random bad luck instead of a fixable pattern. Reviewing inspection outcomes at that level of detail is what turns raw numbers into a corrective plan.

How quickly do we act on a defect once it is reported?

The gap between a driver noting an issue and a shop resolving it is where most preventable out-of-service events originate. Measure this gap in days, not just whether the repair eventually happened. A defect that sits unresolved for two weeks carries real roadside risk the entire time it goes unaddressed.

Do we know our current standing in FMCSA’s Safety Measurement System?

Reviewing your BASIC percentiles periodically catches a rising trend before it reaches an intervention threshold. A score that looks fine today can move quickly after just a few out-of-service events, since those carry more weight than routine citations. Checking this quarterly, rather than only after a bad inspection, gives you time to react before a compliance review becomes likely.

Common Questions About Out-of-Service Rates

About Out-of-Service Rates and Roadside Inspections

What counts as an out-of-service violation?

A vehicle out-of-service violation is typically a critical mechanical or documentation defect, such as a brake system failure or a missing record of duty status. A driver out-of-service violation usually involves an hours-of-service limit, a missing or expired medical certificate, or an invalid license.

Is the national out-of-service rate the same every year?

No. Over the past eight completed Roadcheck years, the national vehicle rate has ranged from about 16.5% to 23%, without a consistent year-over-year trend.

How is my fleet’s out-of-service rate different from the CVSA Roadcheck rate?

CVSA’s published rate reflects a single 72-hour enforcement event each year. Your fleet’s own rate should be calculated from every roadside inspection your trucks go through across a full year, which gives a more complete picture of your actual performance.

What is a CVSA decal and how does it relate to this metric?

A CVSA decal is issued when a vehicle passes a Level I or Level V inspection without a critical violation. It is valid for up to three months and generally exempts the vehicle from reinspection during that window, making it a useful positive indicator alongside your out-of-service rate.

Does an out-of-service order always mean a fine?

Not always. An out-of-service order stops the vehicle or driver from continuing until the violation is corrected, which is separate from any civil penalty that may also be issued depending on the violation type and severity.

About Lowering Your Fleet’s Out-of-Service Rate

What is the single biggest factor in lowering our rate?

A documented process that catches problems before roadside, rather than reacting after an inspection flags them. Fleets that connect DVIR reporting directly to repair tracking, and that record hours of service automatically instead of by hand, see fewer surprises at the weigh station than fleets relying on manual paperwork.

Can a registered ELD actually lower our out-of-service rate?

A registered, properly functioning ELD reduces the record of duty status and falsification-related violations that are among the most common driver out-of-service categories. It does not address vehicle mechanical issues on its own, which is why pairing it with a documented DVIR and maintenance process matters.

How often should we review our inspection history?

Reviewing it at least monthly lets you catch a pattern, such as repeat violations tied to one truck or one driver, early enough to correct it before it affects your CSA score.

Does our fleet size change what target we should aim for?

The target itself does not change with fleet size, though a single out-of-service event has a larger statistical effect on a small fleet’s rate than on a large one, since the total inspection count is smaller.

What role does driver training play in this number?

A driver who understands what triggers a driver-side out-of-service order, such as an hours-of-service limit or a documentation gap, is less likely to generate one. Training is a direct, low-cost way to reduce driver-side findings.

How does Geosavi support tracking this over time?

We provide an online management portal that keeps your ELD logs, duty status records, and inspection-relevant data organized in one place, so pulling your inspection history and calculating your rate does not require digging through separate paper and digital systems.

Where can I find more compliance-focused reading on related topics?

Our blog covers HOS compliance, DVIR integration, and CSA scoring topics that connect directly to out-of-service risk.

Conclusion

Your out-of-service rate is one of the most honest numbers your fleet has. It is not based on self-reported data or internal estimates. It reflects what an inspector actually found, at the roadside, on your trucks and with your drivers. The national benchmark from the most recent completed Roadcheck sat at 18.1% for vehicles and 5.9% for drivers, and that number has moved within a fairly narrow range for close to a decade without a steady downward trend.

Treating this as a number to track, not just a bad outcome to react to, is what separates fleets that improve over time from fleets that stay stuck near the national average. A registered ELD, a documented DVIR and maintenance process, and regular review of your own inspection history are the practical levers that move this metric, working together rather than as separate fixes.
