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.
