List of DOT Out of Service Violations
Your Complete Guide to the DOT List of Out of Service Violations
Running a safe and compliant trucking operation takes more than just keeping trucks on the road. Every carrier, fleet manager, and safety supervisor must stay on top of the rules that keep drivers and equipment in service. One of the most critical resources in this effort is the list of DOT out of service violations.
This list, maintained and enforced by the Federal Motor Carrier Safety Administration (FMCSA) and the Commercial Vehicle Safety Alliance (CVSA), spells out the exact conditions that can take a driver or vehicle off the road immediately. Ignoring it can mean downtime, fines, and serious risks to both safety and reputation.
In this post, we’ll break down what the list is, why it matters, and how you can use it to strengthen your safety program. At the end, you’ll be able to download the full Out-of-Service Violations List PDF so you can keep it close at hand.
Why the List Matters to Trucking Companies
For trucking companies, this list is more than a government document. It’s a roadmap to risk management and compliance. Failing to stay up to date can mean:
- Immediate downtime: A truck or driver pulled OOS cannot operate until the violation is corrected.
- Lost revenue: Every hour a truck is sidelined equals missed loads and unhappy customers.
- Fines and penalties: Citations can cost thousands and damage a company’s CSA score.
- Increased liability: If an accident occurs with an OOS violation, liability skyrockets.
- Reputation damage: Customers and brokers look for reliable carriers. Frequent OOS orders can sink trust fast.
That’s why every safety department should not only have the latest list of DOT out of service violations but also actively train drivers and staff on how to avoid them.
The Most Common DOT Out of Service Violations
While the full list is extensive, certain violations show up again and again during roadside inspections. Here are some of the most common:
Driver Violations
- No valid CDL or wrong class of license for the vehicle being operated
- Invalid or expired medical certificate
- Hours of service violations (exceeding driving limits, falsifying logs)
- Drug and alcohol violations, including refusing a test
Vehicle Violations
- Brake system defects (cracked drums, air leaks, brakes out of adjustment)
- Tire issues (exposed cords, insufficient tread depth, flat or mismatched tires)
- Steering system defects
- Lighting violations, especially non-functioning brake lights or turn signals
- Load securement failures, such as inadequate tie-downs
Hazardous Materials Violations
- Improper placarding
- Leaking containers
- Improper packaging or labeling
How Inspections Work
When a driver pulls into a weigh station or is stopped for a roadside inspection, inspectors use the CVSA’s North American Standard Inspection Program. Depending on the level of inspection, they may check driver documentation, hours of service records, vehicle condition, cargo securement, and more.
If a violation listed in the DOT out of service criteria is discovered, the inspector will:
- Issue an OOS order
- Mark the violation on the inspection report
- Prevent the driver/vehicle from operating until the issue is corrected
This is why driver training and preventive maintenance are critical. Many violations can be caught long before an inspection if fleets prioritize compliance.
How to Use the Out of Service Violations List
Simply having the PDF isn’t enough. Safety managers should build it into their compliance program:
- Regular Training
- Train drivers on hours of service, logbook compliance, and pre-trip inspections
- Use an online training system like INFINITI Fleet Safety Training to make training consistent and trackable
- Pre-Trip and Post-Trip Inspections
- Require drivers to document and submit thorough inspections
- Spot-check to verify inspections are being done properly
- Safety Meetings
- Review the top OOS violations as part of monthly or quarterly safety meetings
- Highlight real inspection data to show what is catching inspectors’ attention
- Maintenance Programs
- Schedule preventive maintenance to address common OOS equipment violations before they appear on the road
- Audit Readiness
- Conduct internal audits against the OOSC list
- Make sure all driver files, medical cards, and logs are compliant

- Lead to more frequent inspections
- Trigger FMCSA audits
- Affect insurance rates
- Scare off shippers and brokers
By regularly reviewing the DOT out of service violations list and building compliance processes around it, carriers protect not only their trucks and drivers but also their business future.
