3 Inspection and certification

3-7 Record of certification

1. The HV certifier must complete a Heavy Vehicle Specialist Certificate (LT400).

2.The HV certifier must include the Vehicle Identification Number (VIN) on the LT400.

3. The HV certifier must retain one copy of the LT400.

4. The HV certifier must provide one copy of the LT400 to the owner of the vehicle.

5. The HV certifier must hold all documentary evidence involved in the certification process.

One LT400 is required for each aspect of the vehicle that needs to be certified. If a single certifier who is appointed for more than one aspect of a vehicle certifies more than one aspect of the vehicle at the same time, a separate LT400 must be used for each aspect.

For some aspects of the vehicle an additional record of the determination, such as a component identification, usually in the form of a metal plate, must be issued and fixed to the vehicle. For some items, this identification may be impressed directly on to the item.

While a certifier may include an expiry date on the certification documents or certification records (eg identification plates), they are only valid if they are required by the legislation or the standard they are manufactured to, or are required by the Transport Agency. If they are not specifically required they are not to be recorded in Landata (Where expiry dates are not specifically required by the legislation, the standard or the Transport Agency then any certification carried out will be for the life of the vehicle).

Any vehicles or components certified after 1 December 2016 must contain the following information (on the plate or label) as a minimum:
