TR CU 018/2011 is the technical regulation on the safety of wheeled vehicles. It separates conformity requirements for vehicles, individual vehicles and listed components. The correct route depends on the vehicle category, intended use, serial or individual presentation, VIN or model, modifications and available evidence.
Use the regulation as a decision framework rather than as a label for every vehicle document. An electronic passport has a different function from conformity assessment. The first task is to identify the product and route. The next task is to match the vehicle or component to the evidence required for that route.
What TR CU 018/2011 covers
TR CU 018/2011 covers safety requirements for wheeled vehicles and relevant components. The regulation does not treat every item as one undivided product class. It distinguishes vehicles, individual vehicles and listed components.
- Vehicle is the main product object placed within the vehicle route.
- Individual vehicle is handled through an individual route rather than being assumed to follow the same evidence path as a serial vehicle.
- Listed component is assessed as a component object where the regulation applies to that component.
This distinction matters because the same vehicle-related project can contain several objects. A complete vehicle, a single individually presented vehicle and a component are not interchangeable objects for conformity assessment.
Which route applies
The route is selected after the product identity and presentation route are recorded. Do not begin with a document name. Begin with the vehicle or component that must be assessed.
- Identify whether the object is a vehicle, an individual vehicle or a listed component.
- Record the vehicle category and intended use.
- Confirm the serial or individual route.
- Record the VIN or model information available for the object.
- List all modifications and identify the evidence that describes the final configuration.
- Match the resulting information to the applicable conformity assessment route under TR CU 018/2011.
A route cannot be selected reliably from a model name alone. The model identifies the product, while the category, intended use, presentation route and modifications identify the assessment context.
Vehicle category and intended use
Vehicle category is a classification input, and intended use is an application input. Both must be fixed before the evidence is reviewed. A supplier should therefore provide the category and intended use as separate items rather than combining them in a general description.
The intended use can affect how the vehicle is understood within the regulation. A vehicle description that omits its use leaves an important part of the decision record incomplete. The assessment file should state the intended use in the same terms used to describe the vehicle object.
Do not insert a category or use that has not been confirmed by the supplier. If the available documents use different descriptions, resolve the identity of the object before choosing the route.
Serial and individual presentation
The serial or individual route is a separate decision from the question of whether the object is a vehicle. A vehicle may need to be considered through its presentation route, while an individual vehicle must be kept distinct from a serial vehicle record.
For a serial route, the record should connect the vehicle to its model and available identification data. For an individual route, the record should identify the single vehicle and its individual evidence. The decision record should state which route was chosen and why the available product information supports that route.
This prevents a common error. A document for one individual vehicle should not automatically be treated as evidence for every vehicle of a model. Conversely, a model reference should not replace the information needed to identify an individual vehicle.
VIN, model and modifications
VIN and model are identification inputs, not substitutes for conformity evidence. The VIN identifies the vehicle record. The model connects the vehicle to its product description. Neither fact, on its own, proves that the final vehicle configuration follows the applicable requirements.
Modifications must be recorded before the evidence route is finalised. The relevant object is the vehicle in its final configuration, not an earlier configuration described in a model document. Where a modification changes the vehicle description, the assessment record should show the modification and the evidence associated with it.
- Record the VIN where a vehicle has an available VIN.
- Record the model used to identify the vehicle.
- List modifications separately from the original vehicle description.
- Check that the evidence describes the final object being assessed.
This sequence is practical because it keeps identification, configuration and evidence in separate fields. It also makes it easier to explain why a particular route was selected.
What counts as evidence for the decision
Evidence is the material used to connect the identified object with the applicable conformity assessment route. The evidence must relate to the vehicle or component that is actually being assessed.
A useful evidence record answers four questions. What is the object? Which category and intended use apply? Is the route serial or individual? Which VIN, model and modification information describe the final configuration?
| Decision input | Question for the record | Reason |
|---|---|---|
| Object | Is it a vehicle, an individual vehicle or a listed component? | The regulation provides separate requirements for these objects. |
| Classification | Which vehicle category and intended use apply? | These facts define the assessment context. |
| Presentation | Is the case serial or individual? | The route must match the way the object is presented. |
| Identity | Which VIN or model identifies the object? | The record must refer to the vehicle being assessed. |
| Configuration | What modifications are present? | Evidence must describe the final configuration. |
The table is a working checklist, not a replacement for the regulation. It helps the reader locate missing information before a conformity assessment route is chosen.
Vehicles and listed components
A listed component follows a component route when TR CU 018/2011 applies to that component. The component must be identified as a component object, not simply as an unnamed part of a vehicle.
The vehicle route and component route are connected because a component can be used in a vehicle. They remain separate because the object being assessed is different. A vehicle record should not be used as the sole evidence for a listed component, and a component record should not be treated as complete evidence for the vehicle as a whole.
When a project includes both a vehicle and a component, create a separate object record for each. Link the records through the vehicle model or configuration only where the available evidence supports that link.
Electronic passport and conformity assessment
An electronic passport is not the same as conformity assessment. The electronic passport serves a different function from the evidence and decision used to establish conformity.
The presence of an electronic passport does not, by itself, answer which TR CU 018/2011 route applies. The reader must still identify the object, category, intended use, serial or individual route, VIN or model, modifications and supporting evidence.
Keep these functions separate in the file. One record concerns the electronic passport. Another record explains the conformity assessment route. Combining them can hide missing evidence or make an identification document appear to be a conformity decision.
How to use the official source
Practical decision sequence
The shortest reliable sequence is to identify the object, classify its use, select the presentation route, record the vehicle identity, disclose modifications and then review the supporting evidence.
- Describe the object precisely.
- Separate the vehicle, individual vehicle and listed component questions.
- Confirm the vehicle category and intended use.
- Choose the serial or individual route.
- Check the VIN or model information.
- Compare the final configuration with the available evidence.
- Keep the electronic passport function separate from conformity assessment.
- Verify the result against the EEC source for TR CU 018/2011.
If a required input is missing, stop at that decision point rather than guessing the route. The final record should show the object, the decision inputs and the evidence that supports the selected path.
Frequently asked questions
Is TR CU 018/2011 the same subject as TP TC 018/2011?
These labels are used in searches for the technical regulation on wheeled vehicle safety. Use TR CU 018/2011 as the consistent name on the working record, then verify the applicable text on the EEC webpage.
Does an electronic passport prove conformity?
No. An electronic passport serves a different function from conformity assessment. The conformity route still requires identification of the object, classification, presentation route, VIN or model, modifications and supporting evidence.
Can a vehicle document cover a listed component?
Not automatically. TR CU 018/2011 separates vehicles and listed components. A component must be identified as its own object and connected to the applicable component route.
What should be checked first for an individual vehicle?
First confirm that the object is an individual vehicle and record its category, intended use, individual route, VIN or model, modifications and available evidence. Then verify the route against TR CU 018/2011.
Use the EEC reference to confirm the final route for the specific vehicle or component record.
Identify the subject of the vehicle record
For a vehicle type, record its model range and variant list. For an individual vehicle, start with its VIN and modifications. For a separately supplied component, check the part number and intended vehicle fitment. These identifiers establish whether the evidence covers the subject of the assessment.
