In trucking, safety and compliance go hand in hand. Roadside inspections are a routine yet critical part of operating a commercial fleet in the U.S. These checks, overseen by the FMCSA (Federal Motor Carrier Safety Administration) and the DOT (Department of Transportation), ensure that both drivers and vehicles meet strict federal standards.For owner-operators and fleet managers alike, being inspection-ready isn't just smart—it's essential. A successful inspection can keep you moving, while a failed one could sideline your truck and disrupt your operations.
What Is a Roadside Inspection?
Roadside inspections are unannounced safety and compliance checks carried out by enforcement officers. They take place at weigh stations, rest areas, terminals, or even along highways. Their main purpose? To ensure that commercial motor vehicles (CMVs) and their drivers meet all federal and state safety regulations.
Why Are Roadside Inspections Conducted?
Roadside inspections serve three primary purposes:
- Safety: Prevent crashes, injuries, and fatalities involving large trucks by keeping unsafe vehicles and drivers off the road.
- Compliance: Ensure carriers adhere to FMCSA and Department of Transportation (DOT) rules.
- Data Collection: Track safety trends and identify high-risk carriers through CSA scores.
Types of Roadside Inspections
The FMCSA recognizes several inspection levels, each varying in scope and detail:
| Level | Focus |
| Level I | Full inspection of both driver and vehicle, including documents and mechanicals. |
| Level II | Walk-around inspection—less detailed than Level I, focuses on visible components. |
| Level III | Driver/credential inspection—focuses on documentation, hours of service, and credentials. |
| Level IV | Special inspection—for specific studies or trends. |
| Level V | Vehicle-only inspection—performed without the driver present (often at terminals). |
| Level VI | For vehicles transporting hazardous or radioactive materials. |
| Level VII | Jurisdictional mandated inspections, e.g., for school buses or limos. |
| Level VIII | Electronic inspection—credentials are checked remotely while the vehicle is en route. |
The most common are Levels I–III, and both drivers and fleet managers must be ready for any of them.
What Do Inspectors Look For?
During a roadside inspection, certified officers use a standardized checklist based on the inspection level. In a comprehensive Level I inspection, they typically review:
| Driver-Related Items | Vehicle-Related Items |
| Commercial driver's license (CDL) | Brake, electrical, exhaust, and fuel systems |
| Hours of service and records (e.g., ELD logs) | Lighting (headlamps, taillamps, turn signals) |
| Medical examiner's certificate | Tires, wheels, and rims |
| Skill Performance Evaluation (SPE) certificates, if applicable | Windshield wipers and condition |
| Alcohol/drug use | Cargo securement |
| Seatbelt usage and safety equipment | Coupling devices and driveline |
| Steering and suspension mechanisms | |
| Frame, trailer, and body condition |
Common Violations to Avoid
Frequent violations that result in fines or out-of-service (OOS) orders include:
Top Driver-Related Violations
- Operating Without a Commercial Driver's License (CDL)
- Electronic Logging Device (ELD) and Hours of Service (HOS) Violations
- Improper or Missing Medical Certification
- Improper Use of Personal Conveyance Exception
- Drug and Alcohol Violations
Top Vehicle-Related Violations
- Lighting Violations
- Brake System Defects
- Tire Issues
- Defective or Missing Emergency Equipment
- Failure to Carry or Provide Proof of Required Inspections
Top Unsafe Driving Violations
- Speeding
- Failure to Obey Traffic Control Devices
- Following Too Closely and Improper Lane Changes
Many of the top violations—such as documentation errors, defective vehicle equipment, and logbook issues—can be mitigated with regular driver training and thorough pre-trip inspections.
Focusing on these common violations helps carriers reduce the risk of OOS orders and enforcement penalties, thereby protecting both their finances and reputation.
When Do Inspections Happen?
Roadside inspections for carriers are conducted year-round, not just once a year. Truck drivers and carriers must be prepared for inspections at any time, as these can occur:
- Randomly at weigh stations and checkpoints.
- During routine traffic stops.
- After visible violations or suspicious driving behavior.
- During targeted enforcement events, like CVSA's International Roadcheck, a multi-day annual blitz when thousands of inspections are conducted across North America.
In short, they can happen at any time, and preparation must be ongoing.
What Happens After an Inspection?
If violations are found, the inspector provides a Driver/Vehicle Examination Report (DVER). If the issues are serious, the vehicle or driver may be placed out of service until the problems are resolved. Carriers are obligated to correct the defects, sign, and return the inspection report within 15 days, and retain a copy for a minimum of 12 months.
A prompt response will not only improve safety but also positively impact the carrier's CSA score, which directly affects insurance rates and future business opportunities.
How Carriers and Drivers Can Prepare
Inspection readiness starts before the wheels roll. Make these practices part of your daily operations:
- Conduct thorough pre-trip and post-trip inspections.
- Keep all documentation updated and organized (CDL, medical cards, logbooks)
- Perform regular vehicle maintenance and repairs.
- Train drivers on inspection protocols and best practices for interacting with inspectors.
- Monitor CSA scores and take corrective actions to address any problem areas.
Preparation builds confidence on the road—and trust with clients, brokers, and enforcement agencies.
Inspections may feel like a disruption, but they play a vital role in protecting both drivers and the public. Carriers who stay inspection-ready not only reduce risk, they also boost operational efficiency, lower insurance costs, and strengthen their reputation with clients and regulators alike.
