CVSA Level VI Inspection: Radioactive Materials Inspection Guide
The CVSA Level VI inspection is a specialized, enhanced inspection for vehicles transporting radioactive materials — specifically transuranic waste and highway route controlled quantities. It includes a full Level I inspection plus additional radiological checks. Here's what it involves.
What Is a CVSA Level VI Inspection?
A Level VI inspection is an enhanced inspection for radioactive materials defined by the Commercial Vehicle Safety Alliance (CVSA). It includes everything in a Level I inspection (37 steps covering the driver and vehicle) plus additional radiological-specific checks. It applies specifically to shipments of transuranic waste and highway route controlled quantities (HRCQ) of radioactive materials, most commonly associated with shipments to the Waste Isolation Pilot Plant (WIPP) in New Mexico.

How Level VI Differs from Other Levels
Key Difference
Level VI builds on top of Level I. The entire 37-step Level I inspection is performed first, then additional radiological checks are conducted. These additional checks verify proper packaging, labeling, placarding, radiation levels, contamination levels, and compliance with nuclear regulatory requirements. This is the most specialized inspection level in the CVSA system.
Who Gets a Level VI?
Level VI inspections are required for shipments of transuranic (TRU) waste destined for the Waste Isolation Pilot Plant (WIPP) in Carlsbad, New Mexico, and for highway route controlled quantities (HRCQ) of radioactive materials, such as spent nuclear fuel. These inspections are performed by specially trained and certified inspectors — not every CVSA-certified inspector can perform a Level VI.
Additional Radiological Checks
Beyond the standard Level I inspection, the following radiological-specific items are checked:
Radiological Documentation
Shipping Papers & Documentation
- Proper shipping name, UN identification number, and hazard class
- Activity (amount of radioactivity) in appropriate units
- Transport Index (TI) and Criticality Safety Index (CSI) where required
- Package type certification and approval documentation
- Emergency response information and 24-hour contact number
- Advance notification to state governor or designee (for HRCQ)
Package & Labeling Inspection
Package Integrity
- Package type matches documentation (Type A, Type B, etc.)
- Package is in good condition — no visible damage, dents, or corrosion
- Closures are secure and tamper-evident seals are intact
- Tie-down devices are adequate and properly secured
- Package temperature is within acceptable limits
Labels & Markings
- Correct radioactive labels (White-I, Yellow-II, or Yellow-III)
- Labels on two opposite sides of the package
- Transport Index and contents marked on labels
- UN identification number displayed
- Proper vehicle placards (RADIOACTIVE) on all four sides
Radiation Monitoring
Radiation Level Measurements
- Measure radiation levels on the surface of the package — must not exceed regulatory limits
- Measure radiation levels at 1 meter (3.3 feet) from the package surface
- Verify the Transport Index matches the measured reading
- Measure radiation levels in the cab and any occupied space — must be within safe limits
- Check for removable surface contamination (wipe tests)
- Verify compliance with dose rate limits for the vehicle exterior
Radiation Limits
Federal regulations set strict limits on radiation levels. The maximum radiation level at any accessible surface of the package is 200 mrem/hr for exclusive-use vehicles. The maximum at 2 meters from the vehicle surface is 10 mrem/hr. The maximum in any occupied position (cab) is 2 mrem/hr. Any readings above these limits will result in the shipment being stopped.
What a Level VI Does NOT Include
Level VI is the most comprehensive inspection level. However, it has specific limitations:
Not a Nuclear Regulatory Inspection
- Does not replace NRC or DOE safety inspections
- Does not verify the contents of sealed packages
- Does not perform internal package inspections
- Does not test package structural integrity beyond visual check
Limitations
- Only applies to TRU waste and HRCQ shipments
- Regular radioactive material shipments use Level I with hazmat checks
- Requires specially trained inspectors — not available everywhere
- Typically conducted at pre-designated inspection points along the route
Route Requirements & WIPP Shipments
WIPP Transportation Program
The majority of Level VI inspections are associated with the Waste Isolation Pilot Plant (WIPP) transportation program. WIPP shipments of transuranic waste follow pre-approved routes and are subject to Level VI inspections at designated points along the route. The DOE, in cooperation with state agencies and CVSA, coordinates these inspections to ensure the highest level of transportation safety.
Route Requirements
- Must use designated highway routes
- Route deviation requires advance approval
- Real-time satellite tracking of shipments
- Communication equipment required at all times
- Advance notification to all states on the route
Driver Requirements
- Valid CDL with hazmat endorsement
- Specialized radioactive materials training
- Security plan awareness training
- Emergency response training specific to radiological incidents
- Background check and security clearance
How to Prepare for a Level VI Inspection
Vehicle & Driver
- Pass a full Level I inspection first — vehicle and driver must be compliant
- Ensure CDL with hazmat endorsement is current
- Carry all required radiological documentation
- Complete all required training certifications
- Ensure communication equipment is functional
Cargo & Packaging
- Verify all packages are properly labeled and marked
- Confirm radiation levels are within limits before departure
- Secure packages with appropriate tie-downs
- Ensure tamper-evident seals are intact
- Carry wipe test results and package certification documents
- Verify placards are visible on all four sides of the vehicle
All CVSA Inspection Levels
The CVSA defines eight inspection levels. Level VI is a specialized radiological inspection:
Level I: Full Inspection
The most comprehensive inspection — includes going under the vehicle. 37 steps.
Level II: Walk-Around Inspection
Driver and vehicle exterior inspection without going under the vehicle. 31 steps.
Level III: Driver/Credential Inspection
Driver-only inspection — no vehicle mechanical checks. 13 steps.
Level IV: Special Inspection
One-time examination of a particular item for studies or trends.
Level V: Vehicle-Only Inspection
Full vehicle inspection without a driver present. 25 steps.
Level VII: Jurisdictional Inspection
Jurisdiction-specific programs for school buses, limos, taxis, etc.
Level VIII: Electronic Inspection
Conducted electronically while the vehicle is in motion.
