Vehicle modifications

Engineering certification

Some vehicle modifications and some imported vehicles may need engineering certification.

You will have to contact an approved engineer and pay a fee that is set by the private business.

The following table contains engineers who are recognised in the Northern Territory (NT) and may:

  • undertake technical assessments
  • issue certificates for modifications.
