Separate LT400 for each Land Transport Rule section or clause, code or standard
An LT400 can only be used for compliance to one Land Transport Rule, standard, or code. A separate LT400 is required for each Land Transport Rule section or clause, code or standard which is applicable to the vehicle in question. That is, the 'Code/Standard/Rule certified to' box must contain only one section or clause of a Land Transport Rule or refer to only one code or standard.

Component | Certification category | Code/standard certified to |
|---|---|---|
Fifth wheel | HVET or HVTD | NZS 5450 |
King pin | HVET or HVTD | NZS 5451 |
Load anchorages | HVEA or HVAD | NZS 5444 |
Log bolsters | HVEL or HVLD | Bolster Attachment Code |
