Intermodal Chassis Inspection: Ultimate Guide

An intermodal chassis inspection is your first line of defense against costly downtime and dangerous situations on the road. For fleet owners and safety managers, you know that picking up a chassis from a pool can be a real gamble. The pressure to just hook up and get moving is intense, but skipping this crucial check can lead to roadside breakdowns, expensive fines, and hits to your safety score.

You’ve seen the mixed bag out in the yard—some chassis look brand new, while others are clearly on their last legs with bald tires and busted lights. You might feel rushed, but that quick hook-and-go can turn a ten-minute shortcut into an hours-long delay on the side of the highway.

This guide is your practical, no-nonsense walkthrough for a fast yet effective intermodal chassis inspection. We will show you exactly what to focus on based on your specific responsibilities under DOT regulations, helping you keep your drivers safe and your fleet compliant.

 

What This Guide Covers

This guide is designed to clarify your responsibilities versus those of the Intermodal Equipment Provider (IEP). While the IEP is generally on the hook for the frame, suspension, and brake system, you and your drivers are accountable for specific roadability components. As you develop your own inspection process, focusing on writing clear procedures will ensure everyone on your team performs a consistent and effective check, every single time.

We’re going to zero in on the five key areas you are responsible for inspecting every time you pick up a chassis:

• Tires
• Hubs
• Wheels
• Lighting
• DOT Reflective Tape

Think of this as your roadmap to starting every haul safely and compliantly. For a broader look, you can also check out our guide on the complete trailer DOT inspection, which covers a lot of similar ground. By mastering these key inspection points, you protect your drivers, your carrier’s safety score, and everyone else sharing the road.

Why Your Inspection Is Critical to Safety and Uptime

That intermodal chassis inspection is one of the single most important things you can do to protect your time, your CSA scores, and your safety out on the road. If you’re a fleet owner or safety manager, making this check a non-negotiable part of your drivers’ daily routine is one of the smartest risk-reduction moves you can make. It’s a few minutes that can easily save you hours of downtime and hundreds in fines and dozens of CSA points.

We all know that all chassis are not created equal. When you pull a chassis from a pool, you’re essentially rolling the dice on its condition. While Intermodal Equipment Providers (IEPs) are on the hook for major systems like brakes and frames, the immediate roadworthiness of tires, wheels, and lights falls squarely on your shoulders before you leave the gate.

The Stark Reality of Chassis Pools

The quality of equipment out there can be a total crapshoot. It varies wildly between providers and even between different terminals run by the very same company. This isn’t just a hunch; federal data backs it up. You will see some chassis providers with an Out of Service (OOS) rate near zero, while others have numbers that should make any driver nervous.

Just look at FMCSA data from 2019. One provider’s Southern California pool had a respectable 2.60% OOS rate after 106 chassis inspections. But their Atlantic Region operation? A 15.69% OOS rate from a sample of only 67 chassis. That large difference tells you everything you need to know: you cannot assume any piece of equipment is good to go.

 

A high OOS rate at a terminal means more headaches. You’re looking at more delays, more trouble tickets at the gate, and a much higher chance of getting stuck with a junk chassis. This risk gets even worse during peak seasons when chassis are being turned over like pancakes.

 

Protecting Your CSA Score and Your Time

This 15-minute pre trip inspection  is one of the most valuable investments you can make in your day. A roadside inspection that turns up a defect you should have caught (like a bad tire or a dead light) nets you a violation that hits your company’s Compliance, Safety, Accountability (CSA) score. Those points add up, leading to more DOT scrutiny, higher truck insurance premiums, and even lost customers. You can get a better feel for what officers are hunting for during events like the annual CVSA Roadcheck.

Here’s a list of the most common intermodal chassis related violations and the CSA points associated with each one. 

 

Violation Code	Violation Name	CSA Points
393.75A	Flat tire or fabric exposed	8
393.75A3	Tire-flat and/or audible air leak	8
393.75C	Tire-other tread depth less than 2/32 of inch	8
393.207(b)	Adjustable axle locking pin missing/disengaged	7
393.126	FAIL TO ENSURE INTERMODAL CONTAINER SECURED	7
393.9A	Inoperable Required Lamp	6
393.9T	Inoperable Tail Lamp	6
393.9TS	Inoperative Turn Signal	6
396.5B-HWSLOW	Hubs – Wheel seal leaking – outer wheel	6
393.25F	Stop Lamp Violations	6
393.45B2PC	Brake Hose or Tubing Chafing and/or Kinking – Connection to Power Unit	4
393.45PC	Brake Tubing and Hose Adequacy – Connections to Power Unit	4
393.55E	No or Defective ABS Malfunction Indicator Lamp for trailer manufactured after 03/01/1998	4

 

As you can see, tire violations and lighting violations will still have a serious impact on your vehicle maintenance CSA score. For intermodal chassis, you also have to focus on proper locking pin engagement to avoid those tough 7 severity point violations.  

A proper intermodal chassis inspection is not just about dodging tickets. It’s about making sure you can actually finish your run without a major headache. A tire blowout or a wheel-end failure on the road could translate to hours stuck on the shoulder waiting for a service truck, a missed delivery appointment, and a completely wrecked schedule.

By taking control and doing a consistent, thorough inspection every single time, you flip the odds back in your favor. You spot problems at the source, reject unsafe gear, and create a paper trail showing you did your due diligence. It is a simple habit that safeguards your time, your record, and your safety on every single haul.

When you pull up to a chassis in the pool, it is easy to feel overwhelmed. There are a ton of parts, and it can seem like you need to inspect every single nut and bolt. But that is not the case. A good intermodal chassis inspection is a quick, focused safety check before you hit the road.

The secret is knowing what you are legally responsible for versus what the Intermodal Equipment Provider (IEP) has to maintain. While the IEP is on the hook for major systems like the brakes, frame, and suspension, federal rules put the responsibility for a few critical components squarely on your shoulders. These are the “roadability” items you must verify are safe before leaving the terminal.

Focusing on these five areas will make your inspection fast, effective, and, most importantly, compliant. A good inspection process is what separates a well-maintained chassis from one that is a serious risk on the road. Starting with a reliable IEP definitely improves your odds, but as any seasoned driver knows, a bad chassis can come from anywhere. Your inspection is the final, critical checkpoint before you roll.

Before we dive in, it’s crucial to understand who is responsible for what. It’s a common point of confusion that can lead to violations.

Chassis Inspection Responsibility Checklist

This table breaks down the typical responsibilities between you (the driver/carrier) and the IEP. Keep in mind, this is a general guide; your specific interchange agreement might have slight variations.

Component	Your Responsibility (Driver/Carrier)	IEP’s Responsibility (Chassis Owner)
Tires	Verify tread depth, inflation, and check for visible damage (cuts, bulges).	Systemic maintenance, replacement of worn-out tires, major repairs.
Wheels/Hubs	Check for loose/missing lug nuts and signs of leaking hub seals (oily streaks).	Bearing maintenance, seal replacement, and addressing structural wheel damage.
Lights	Confirm all required lights are operational (brake, tail, turn signals, markers).	Repairing wiring issues, replacing bulbs/lenses, and overall system integrity.
Reflective Tape	Ensure tape is present, clean, and not overly damaged.	Initial application and replacement of large, missing sections to meet standards.
Brakes	A quick visual check for obvious issues like audible air leaks.	Full brake system maintenance, adjustments, and component replacement (as per § 396.12).
Frame/Structure	Note any severe, obvious cracks or breaks in the frame.	Maintaining the structural integrity of the chassis, including crossmembers and rails.

Ultimately, you are responsible for ensuring the chassis is safe before you pull it. Documenting defects on your Driver Vehicle Inspection Report (DVIR) is your proof that you did your job.

1. Tires: The Foundation of Your Haul

We all know that tires are the number one cause of roadside headaches and downtime. A quick but thorough tire check is absolutely essential. Look past the obvious flats and get into the details that DOT officers are trained to spot.

Here’s your checklist:

• Tread Depth: All chassis tires require a bare minimum of 2/32-inch. The easiest check? If the little tread wear indicator bars are flush with the tread, that tire is illegal.
• Sidewall Damage: Scan both the inner and outer sidewalls. You’re looking for deep cuts, cracks, or any noticeable bulges. A bulge is an automatic out-of-service condition; it signals internal damage and a huge risk of a blowout.
• Inflation: You can’t always eyeball this, but a visibly low tire is a massive red flag. If it looks soft, it needs air, period. Giving it a good whack with a tire thumper can also give you a feel for a low one, but a gauge is the only way to be 100% sure.

2. Hubs: Look for the Telltale Streaks

Inside those wheel hubs is the grease or oil that keeps your wheel bearings from seizing up. A failing hub seal is a serious fire hazard and can lead to a wheel coming off entirely. Luckily, the warning signs are usually easy to spot.

You’re looking for dark, oily streaks radiating out from the center of the wheel. This is the classic sign of a leaking hub seal. If the leak looks fresh and wet, that is an immediate out-of-service defect. Even if it looks old and dry, it points to a recurring problem that should be documented on your DVIR.

 

Never, ever ignore a leaking hub. It is a textbook example of a small problem that can turn into a catastrophic failure on the highway. A five-second look here can prevent a disaster.

 

3. Wheels: Rims and Lug Nuts

Next, give the wheels a close inspection. You’re looking for two main things: the integrity of the rim itself and the security of the lug nuts. Problems in this area can develop fast and lead to a wheel separating from the chassis. Check out this short video on wheel end inspection tips:

 

Your wheel check should cover:

• Cracked or Bent Rims: Check the rim for any visible cracks, paying close attention to the area around the lug holes and where the rim meets the tire. Also, look for any serious bends from hitting curbs.
• Loose or Missing Lug Nuts: Look for rust trails coming from a lug nut—it’s a dead giveaway that the nut has worked itself loose. Do a quick visual sweep to make sure all lug nuts are present and look tight.
• Dayton vs. Budd Wheels: If it is a Dayton-style (spoke) wheel, check the clamps and spacers to be sure they’re secure. For Budd-style (disc) wheels, that lug nut check is your main focus.

4. Lighting Systems: Be Seen and Be Safe

Inoperable lights are one of the most common (and most avoidable) violations out there. They kill your visibility, put you at risk, and basically paint a target on your back for inspectors. A quick walk-around is all it takes.

Hook up your pigtail and run through this sequence:

• Brake Lights: Use a brake pedal depressor or ask a spotter to confirm all brake lights are working.
• Tail Lights: Make sure both tail lights are on when your headlights are active.
• Turn Signals & Hazards: Check your left and right signals, then hit the four-way flashers to see them all blink.
• Marker & Clearance Lights: Verify all amber lights on the front/sides and all red lights on the rear are lit.

A busted light is an easy fix at the terminal but a costly ticket on the road.

5. DOT Reflective Tape: Visibility Is Key

Finally, give the DOT reflective tape a quick look. This tape is essential for making sure other drivers see you at night, and if it is damaged, missing, or covered in grime, it is a violation.

Do a quick scan of the sides and rear of the chassis. The red-and-white reflective tape needs to cover at least 50% of the sides and run across the entire rear underride guard and bumper. If it is so caked in dirt that it will not reflect light, you are not compliant. Sometimes, a quick wipe with a rag is all it takes to fix the problem.

Documenting Defects and Taking Corrective Action

Finding a problem during your intermodal chassis inspection is only the first part of your job. What you do next is what really matters; it’s what protects you, your CSA scores, and your company from a nasty roadside violation or, even worse, a preventable accident. Trust me, ignoring a bad tire or a busted light is a gamble that almost never pays off in the long run.

This is where your Driver Vehicle Inspection Report (DVIR) becomes your best friend. It’s not just more paperwork; it’s a legal record that proves you did your job and identified a defect before hitting the road. Proper documentation is your professional shield.

Creating an Actionable DVIR

Just jotting down “light out” does not cut it. A solid DVIR needs to be crystal clear, specific, and leave zero room for interpretation. This not only tells the maintenance crew exactly what needs fixing but also creates an undeniable paper trail of the issue you found.

Here’s how you can describe common defects with the detail that matters:

• Tires: Instead of “bad tire,” write, “Inside dual tire on driver’s side rear axle has tread depth below 2/32 inch.”
• Lights: Do not just say “light out.” Specify, “Passenger side rear clearance marker light is inoperable.”
• Hubs: “Hub leak” is too vague. Document it as, “Wet, oily streaks observed coming from hub seal on driver’s side front axle.”
• Reflective Tape: Instead of “tape bad,” note, “Required red/white reflective tape is missing from rear underride guard.”

This level of detail is absolutely critical. 

Rejecting a Bad-Order Chassis

If your inspection uncovers a serious defect that makes the chassis unsafe, you have to reject it. This is what we call “bad-ordering” the equipment. It might feel like a pain and a delay at the moment, but it’s nothing compared to the massive headache of an out-of-service violation on the road.

The process is pretty straightforward:

1. Document Everything: Immediately write down all the defects on your DVIR with those specific details we just talked about.
2. Notify the Gate or Dispatch: Let the terminal personnel or your dispatcher know the chassis is unsafe and that you’re rejecting it.
3. Request a Replacement: Politely but firmly ask for another unit.
4. Keep Your Records: Always hold on to a copy of the DVIR that shows the defects you found on that rejected chassis.

 

The global market for intermodal chassis repair services hit $1.97 billion in 2024. At busy ports, it’s not unusual for 20-30% of chassis to get flagged with trouble tickets from failed roadability checks, causing major backups for everyone. When you reject bad equipment, you’re doing your part to keep unsafe units off the highway.

 

The Power of Good Documentation

Your detailed DVIR is way more than just a report; it is a vital compliance tool. It acts as your legal defense if an incident happens, showing you performed your due diligence as a professional driver. For fleet managers, these reports are a goldmine of data on equipment quality from different IEPs and terminals.

When you consistently document issues, you start to see patterns. Maybe one particular chassis pool always seems to have tire problems. This data lets you go back to the provider with concrete evidence. Managing these records efficiently is crucial, which is why having a rock-solid system for your DVIRs is a must-have for any compliant fleet.

Integrating Chassis Inspections into Your Fleet Safety Program

For any fleet owner or safety manager, a solid intermodal chassis inspection process is a pillar of a strong DOT compliance program. It’s not about just telling your drivers to “do an inspection.” You need a bulletproof system that makes sure it gets done right, every single time. This is how you turn a daily driver task into a powerful fleet management tool.

A proactive approach goes way beyond just hoping inspections get done. It is about building a genuine culture of safety where thorough checks are the standard, not just another box to check. This kind of system is what separates compliant, efficient fleets from those constantly putting out fires.

From Driver Task to Fleet Management Tool

The first move is to bake the inspection process into your formal safety policy. This means training your drivers on those five key inspection areas and making it crystal clear that no chassis moves without a proper pre-trip check. This has to be a non-negotiable part of your operation.

Once you formalize the process, it becomes much easier to track and manage. You can use compliance management tools to watch Driver Vehicle Inspection Reports (DVIRs) come in, giving you a real-time view of what your drivers are dealing with out in the field.

 

By tracking DVIR data, you can start to connect the dots on recurring equipment problems. Are bad tires always coming from a specific chassis pool? Are you seeing a lot of light-out violations from a certain terminal? This is not just about fixing one issue; it is about spotting systemic problems that are costing you time and money.

 

This data gives you the ammo you need to have productive conversations with Intermodal Equipment Providers (IEPs) about the quality of their gear. It’s hard for them to argue with a documented history of defects all coming from one of their locations.

Using Data to Drive Down Risk

The global intermodal chassis market is huge; projected to climb from $1.95 billion in 2024 to $2.68 billion by 2030. While most providers are trying to do the right thing, perfect compliance is still a major hurdle. Top-tier providers have shown it’s possible, hitting a 0.00% OOS rate in FMCSA inspections and demonstrating what a real commitment to quality looks like.

When you track inspection data, you can start making smarter business decisions. You’ll be able to coach drivers on what to look out for at problematic terminals or even route them away from locations known for shoddy equipment. This proactive strategy saves countless hours that would otherwise be wasted on roadside repairs and frustrating delays at the gate.

A strong inspection and documentation system is a critical piece of any successful fleet safety program. To help you build out your own policies, you might find our free fleet safety program template useful.

At the end of the day, weaving chassis inspections into your safety program transforms the daily pre-trip from a simple driver duty into a strategic asset. It helps you cut down on risk, lower costs, and build a tougher, more resilient fleet. A reliable compliance partner (like My Safety Manager) can help you manage this entire process, ensuring every single inspection adds real value to your operation.

Key Regulatory References for Chassis Inspections

To keep your operations compliant, you have to know the rules. When it comes to intermodal chassis inspections, the requirements are not just suggestions—they are spelled out in black and white in the Federal Motor Carrier Safety Regulations (FMCSR). Knowing these regulations helps you understand why these inspections are a legal mandate, not just a “nice to have.”

Think of these as the foundation of your chassis inspection program. It is a good idea to get familiar with them to make sure your safety procedures are built on solid ground.

Here are the big ones you need to know:

• § 392.7 Equipment, inspection and use: This is the core rule. It flat-out states you cannot operate a commercial motor vehicle unless you are satisfied it is in good working order. This puts the responsibility for that pre-trip inspection squarely on your shoulders.
• § 393.11 Lamps and reflective devices: Ever wonder exactly what lights and reflective tape are required? This regulation lays out the specific requirements for every lamp, reflector, and piece of conspicuity tape on a CMV, including a chassis. It’s the “why” behind the lighting and tape part of your inspection.
• § 396.11 Driver vehicle inspection report(s): This is all about documentation. It details your duty to complete a Driver Vehicle Inspection Report (DVIR) and officially note any defects you find that could impact safe operation. If you find it, you have to write it up.
• § 396.13 Driver inspection: This rule backs up § 392.7, mandating that you perform that pre-trip inspection and be satisfied that the vehicle is safe before you hit the road. No ifs, ands, or buts.

Building a compliant and safe operation really does start with understanding these rules. If you need help weaving these requirements into a simple, easy-to-use safety program, check us out at www.MySafetyManager.com.
