DOT inspection checklist: Levels 1–3, what to have in the cab, and CSA
What a roadside DOT inspection covers at Level I, II and III, the documents to keep in the cab, how out-of-service orders work, and how violations feed your CSA scores.
A roadside inspection is not a test of how well your driver drives. It is a check of whether the paperwork exists, whether the truck is in the condition the regulations require, and whether the driver is legal to be behind the wheel at that moment. Most of what goes wrong at the scale was decided days earlier, in a file nobody updated or a light nobody replaced. This guide explains what inspectors look at, what the driver should have within reach, what an out-of-service order means, and how each violation follows your company around for two years in CSA.
One-time check of a specific item, usually for a study
V
Vehicle only
The Level I vehicle items with no driver present, typically at a terminal
VI
Radioactive
Level I items with stricter rules for certain radioactive shipments
For a dry van or reefer carrier, Levels I, II and III are the ones that happen. A Level III takes a few minutes and is mostly about the driver. A Level I takes an hour or more and puts the truck on a pit or a creeper.
What a Level I checks
On the driver side, South Dakota lists: the driver’s license, the medical examiner’s certificate and any waiver, alcohol and drugs, the record of duty status and hours of service, the vehicle inspection report and the annual vehicle inspection (SD Highway Patrol). On the vehicle side it covers the mechanical parts and systems, coupling devices, lamps on projecting loads, safe loading, and hazardous materials requirements where they apply. The inspector walks around, gets under the truck, and checks brakes, tires, lights, steering, suspension, the fifth wheel and the trailer.
A Level II is the same list minus anything that requires going underneath. A Level III is the driver items only: license, medical certificate and waiver, record of duty status and hours of service, seat belt, the vehicle inspection report and hazmat paperwork where it applies (SD Highway Patrol).
The cab checklist
The driver should be able to hand over each of these without searching. Keep the paper copies in one folder and the digital ones on the phone.
CDL with the endorsements the load needs, and the medical examiner’s certificate (and any waiver or exemption that goes with it).
Hours of service. On an ELD, the driver must be able to show the current day and the previous seven days on the device and transfer them to the inspector. FMCSA requires an information packet in the vehicle: the ELD user’s manual, an instruction sheet for transferring records to an official, an instruction sheet on what to do when the device malfunctions, and enough blank paper log grids for at least 8 days (FMCSA ELD FAQ: required user documentation). A driver who cannot transfer the logs is treated as a driver without logs.
Registration and cab card. The apportioned cab card listing the IRP jurisdictions, and the trailer registration.
Proof of insurance for the tractor and, where separate, the trailer.
Annual inspection. The inspector checks that the annual inspection was done; carry the report or make sure the sticker is current and legible.
IFTA decals on both sides of the cab and a copy of the IFTA license. Permits for weight-distance states (New York, Kentucky, New Mexico, Oregon) if you run them.
Load paperwork: the bill of lading, the rate confirmation and, for a reefer, the temperature instructions. Hazmat shipping papers in the driver’s door pocket or seat when it applies.
The last driver vehicle inspection report if a defect was noted, with the repair signed off.
Before the truck leaves the yard
Most Level I vehicle violations are things a pre-trip would have caught: a marker light out, a tire under pressure or worn to the cords, a brake out of adjustment, an air leak you can hear, a cracked mirror, a loose mud flap, a fifth wheel that was not locked. The driver’s pre-trip is the inspection you do on your own terms. Make it a real walk-around with the lights on and a tire gauge, not a glance from the driver’s seat, and give the driver a way to report a defect that gets it fixed before the next dispatch instead of after the next scale.
Out-of-service orders
When an inspector finds a defect serious enough, the vehicle or the driver is placed out of service. South Dakota’s description is typical: an out-of-service sticker is applied to vehicle units placed out of service when major defects are found, and the driver gets a copy of the inspection report (SD Highway Patrol). A vehicle out-of-service order means the truck or trailer cannot move until the defect is repaired, which usually means a mobile mechanic at the scale or a tow to a shop. A driver out-of-service order means that driver cannot drive until the condition is cleared, most often an hours-of-service violation that ends when the required rest is taken, or a missing medical certificate that ends when the document is produced.
Either way, the load is late, the driver is sitting, and the violation carries extra weight in CSA (next section). The cost of an out-of-service order is almost always many times the cost of the repair that would have prevented it.
CVSA decals
A truck and trailer that pass a Level I or Level V inspection with no serious defects can receive a CVSA decal. Inspectors in other member states may waive inspection of a vehicle displaying a current decal (SD Highway Patrol). It is not a guarantee of being waved through, but a current decal on the windshield shortens a lot of stops.
How violations hit CSA
Every roadside inspection, clean or not, goes into FMCSA’s Safety Measurement System under your USDOT number. FMCSA’s own introduction to the system explains the mechanics (FMCSA: Introduction to the Safety Measurement System):
Violations are grouped into seven categories, the BASICs: Unsafe Driving, Hours-of-Service Compliance, Driver Fitness, Controlled Substances and Alcohol, Vehicle Maintenance, Hazardous Materials Compliance, and the Crash Indicator.
The system looks back 24 months. Recent events count more: a violation in the last six months is weighted three times, six to twelve months twice, and older than a year once.
Each violation has a severity weight from 1 to 10 based on its link to crash risk. In the Hours-of-Service, Driver Fitness, Vehicle Maintenance and Hazmat BASICs, an out-of-service violation adds 2 more.
Your result in each BASIC is a percentile against carriers with a similar number of inspections. A higher percentile is worse, and crossing the intervention threshold for a BASIC puts you in line for a warning letter, an investigation or worse.
Two consequences for a small carrier. First, with few inspections, one bad one moves your percentile a long way, because the comparison group is other carriers with few inspections. Second, clean inspections help: each one adds to the denominator. A carrier whose trucks are inspected often and found clean looks safer than one that is rarely inspected. FMCSA has published proposed changes to how the system groups and weights violations; the current methodology is on the CSA site.
What to do after an inspection
Get the inspection report from the driver the same day, clean or not, and file it with the truck.
Fix every noted defect and keep the repair invoice with the report.
Check the inspection in FMCSA’s system when it posts. If a violation is wrong, was not yours, or was cited against the wrong carrier, file a request for data review in FMCSA’s DataQs system with the documents that prove it. Inspection data can be challenged for three years from the inspection date (Colorado State Patrol: challenge an inspection violation). A DataQs review does not touch a ticket; that goes to the court or agency that issued it.
If the same defect keeps showing up, change the pre-trip, not the driver.
Keeping the dates that cause Level III violations
The driver-side violations are almost all expiry dates: a medical card that lapsed, a CDL that expired, a registration or annual inspection that ran out, insurance that was not renewed. freightline keeps those dates on each driver and truck and shows what is due on the Compliance page and the dashboard, including lawful-status dates for drivers on non-domiciled CDLs (see what freightline tracks for driver compliance), and emails a weekly summary of what is coming due. Hours of service come from the connected ELD on the live map (connect your ELD).
Enter your drivers’ medical card and CDL dates and your trucks’ inspection dates and let the reminders do the remembering. The 30-day trial needs no card, and every plan includes every feature.
Common questions
What is the difference between a Level 1 and a Level 2 inspection?
Both check the driver's documents and the vehicle. A Level I includes everything underneath the truck, such as brakes and suspension; a Level II covers only what the inspector can see without getting under it.
What documents does a driver need for a DOT inspection?
CDL, medical certificate, hours-of-service records for today and the previous seven days with the ELD information packet, registration and cab card, proof of insurance, the annual inspection, IFTA credentials, and the paperwork for the load.
How long does a violation stay on my CSA record?
Roadside inspection results count for 24 months, with violations from the last six months weighted three times, six to twelve months twice, and older than a year once.
Does a clean inspection help my CSA scores?
Yes. Clean inspections add to the number of inspections you are measured against, which lowers your percentile for the same number of violations.
Can I dispute a violation?
Yes, through FMCSA's DataQs system. Attach the documents that show the citation was wrong, such as a repair invoice dated before the inspection or proof the vehicle was not yours.
