What Are DOT Inspections?
A Dot inspection is a safety check conducted on commercial trucks and trailers weighing over 10,000 pounds.
Qualified inspectors from the Department of Transportation or state police officers typically conduct these inspections. These safety checks ensure that large commercial vehicles and truck drivers are safe to ride on the roadway and in compliance with all state and federal regulations.
According to the Federal Motor Carrier Safety Administration (FMCSA), all commercial trucks and trailers over 10,000 pounds must undergo a DOT inspection at least once a year. Some states may also have additional DOT inspection regulations that truckers must follow.
Types of DOT Inspections
There are eight types of DOT inspections officials conduct. The type of inspection conducted depends on the reason for the safety check.
Below is a look at the eight different types of DOT inspections and their purposes.
Level 1: North American Standard Inspections
The Level 1 inspections are the most comprehensive of the eight types. This 37-step tractor-trailer inspection can take anywhere from 30 to 60 minutes or longer.
It includes a comprehensive inspection of the truck and trailer, including an examination under your vehicle. The inspector will physically climb under your truck as part of the inspection.
The inspector or officer makes sure all safety elements, including brakes, tires, and lights, are in good working order and meet regulatory standards. They will also check all driver documentation, including driver’s license, registration, insurance, and ELD book.

Level 2: Walk-Around Driver and Vehicle Inspections
The Level 2 DOT inspection is one of the most common safety checks conducted.
While this inspection level is similar to a Level 1 check, the inspector or officer does not get under the vehicle. Instead, they walk around the entire truck and trailer and only check safety items they can see without physically getting under the vehicle.
Just as with a Level 1 inspection, drivers must show all required documentation, including driver’s license, logbook, and registration. As long as there are no issues and you have all your paperwork in order, a Level 2 DOT inspection should take about 30 minutes to complete.
Level 3: Driver-Only Inspections
While an inspector or officer can conduct Level 3 DOT inspections for various reasons, the most common cause is traffic violations, such as speeding or using a phone while driving. Typically, these inspections are conducted on the side of the road or at the nearest location where the truck and trailer can pull over safely.
As the name suggests, the inspector only checks the driver’s records, including driver’s license, carrier identification and status, hours of service, and vehicle inspection reports. While these inspections typically only take about 15 to 20 minutes to complete, the inspector can upgrade the stop to a Level 1 or Level 2 Inspection if they notice extensive issues with the vehicle.
Level 4: Special Inspections
Inspectors and officers conduct special inspections as part of an ongoing study to track specific features on your vehicle or to note driving trends. This is a one-time inspection that the Commercial Vehicle Safety Alliance or the Federal Motor Carrier Safety Administration uses to gather more information about a specific issue.
A Level 4 inspection could involve details about your driving credentials or vehicle components. Because inspectors are only checking for just one specific feature, it usually only takes a few minutes to complete.
Level 5: Vehicle-Only Inspections
Truck drivers don’t need to be present when inspectors or officers conduct Level 5 inspections. Typically, these examinations are done after an accident where the driver must go to the hospital or after a driver is arrested and taken to the police station.
Level 5 inspections are similar to Level 1 checks, where inspectors and police officers can inspect the entire truck, including physically crawling under the truck and trailer. However, they don’t check any driver documents.

Level 6: Enhanced Inspection for Radioactive Transport Inspections
Level 6 inspections are only conducted on certain trucks and trailers transporting radioactive materials. Inspectors examine all driver information, including carrier identification and status reports, logbooks, and driver’s licenses.
These examinations are conducted before the driver departs.
Once the driver and vehicle pass the Level 6 inspection, a special sticker, noting radioactive material, is attached to the vehicle.
Level 7: Jurisdictional Mandated Commercial Vehicle Inspections
A Level 7 inspection is for commercial vehicles that aren’t required to undergo Level 1 to Level 6 inspections, such as school buses, limousines, shuttle services, and taxis. Each jurisdiction determines who can conduct these types of inspections and dictates training standards.
Level 8: North American Standard Electronic Inspections
Level 8 inspections are conducted electronically without the need for the driver to pull over. Only certain types of vehicles are eligible for this type of inspection, and the trucks must be equipped with the required tracking devices.
This safety check allows inspectors or officers to examine the driver and vehicle information electronically, such as records of duty status, driver’s license, and operating authority.
Why Are DOT Inspections Important?
The Department of Transportation conducts tractor-trailer inspections for a number of reasons.
Safety
Safety is the first and foremost reason for DOT inspections.
Tractor-trailers are a key component of the U.S. economy. Due to their size and weight, these large trucks can also be dangerous if they malfunction.
Conducting regular safety checks can prevent issues from happening on the road. This helps keep all drivers safe.
Compliance
Truck drivers and trucking companies must comply with state and federal regulations. States use DOT safety checks to ensure all drivers and companies remain in compliance with these rules.
Maintenance
A benefit of DOT inspections is that they can help keep your truck in good working condition. A standard DOT safety check could reveal a minor issue with your truck and give you time to fix it before it becomes a more costly problem.
How to Prepare for DOT Inspections: Level 2-6 Checklist
When preparing for a DOT inspection at any level, it’s important to know what to look for.
Below is a look at various items you should frequently check. This DOT tractor inspection checklist is not necessarily all-encompassing, but it’s a good starting point.
Review Your Documents
Start your inspection by making sure all your required documents are in place and easily accessible. This includes:
-
- Driver’s license
- Vehicle registration
- Vehicle insurance
- Carrier identification and status
- Medical Examination Certificate and Skill Performance Evaluation (SPE) Certification
- Vehicle inspection reports
- Hours-of-service (HoS) documents
- Daily logs
Inspect Your Brakes
The examiners can assess all components of your brake system, including:
-
- Any leaks or cracks
- Brake fluid
- Brake pads and shoes
- Brake drums and rotors
- Brake adjustment
- Brake lines and hoses
Check All Lights and Reflectors
Before you head out on the road, make sure all your reflectors are securely in place and that all your lights are in good working condition.
During a DOT inspection, the examiner will walk around the truck and trailer to make sure all your lights are working properly, including:
-
- Headlights
- Taillights
- Clearance lights
- Emergency flashers
- Turn signals
- Brake lights
- License plate lights
Having just one light malfunctioning could put your truck out of commission until it’s fixed.
Ensure Steering and Suspension Are in Good Condition
During a DOT inspection, the examiner looks for wear and tear throughout your steering and suspension systems. This includes a close examination of various parts, such as:
-
- Tie rods
- Steering gearbox
- Drag links
- Airbags
- Left springs
- Shock absorbers
- Trailer alignment
Check Your Tires
Inspectors will inspect every tire on your truck and trailer. They are looking for excessive wear and tear and that your tires are securely in place.
A DOT inspection includes an examination of various components, including:
-
- Depth of tire tread
- Condition of sidewalls
- Tire pressure
- Lug nuts
- Wheel bearings
- Tire alignment
- Mud flaps (if applicable)
Ensure Your Cargo Is Secure
Cargo securement is a key component of DOT tractor inspections. It’s vital that your cargo is securely in place.
The inspector will check your tie-downs by making sure you have enough to keep your cargo secure and that each tie-down is secure.
All tie-downs and holders in use must be in good condition. There should be no worn edges, cracks, chips, or other damage.
The main thing to remember is that your cargo should not shift during transport.

What Happens After a DOT Inspection?
Once the DOT inspection is complete, the examiner will explain their findings to you. If the inspector finds no violations and it’s a Level 1 DOT inspection, you’ll receive a CVSA sticker to attach to your vehicle, along with a Driver Vehicle Examination Report (DVER).
If there are no violations and it’s a Lever 2-8 inspection, you’ll only receive a DVER report. This report includes details of the inspection and should be kept with your Driver Qualification Files.
If, on the other hand, you have one or more violations, several things could happen.
-
- If it’s a minor violation, the officer may just give you a warning and encourage you to make the necessary repairs as quickly as possible. These minor violations could still appear in your DVER report and impact your or your company’s CSA score.
- If more serious violations are found, the inspector could fine you or your company and put you or your vehicle out of service. If this happens, you must correct any violations before you can get back on the road.
- Repeated violations could result in hefty fines and penalties or even cause you to lose your CDL license or face suspension.
To ensure you don’t face any violations on your next DOT inspection, it’s important to conduct frequent safety checks. This step can alert you to issues before you’re stopped for a safety check.
You also want to make sure you stay on top of your paperwork, keep all your documents orderly, and always know where to find any mandatory reports.
