Importing, Exporting & Registering Vehicles

Do imported speedometers need to display mph in Northern Ireland?

For NI road use and testing, the speedometer must provide the required miles-per-hour indication; DfI guidance for vehicles first used from the relevant date also expects mph and km/h unless an approval exception applies.

DfI’s current inspection guidance says mph must be visible on the actual speedometer display. For many vehicles first used on or after 1 April 1984 the instrument is expected to indicate both mph and km/h, either simultaneously or through a switchable display.

A vehicle with a departmental SVA/IVA approval certificate can have a different inspection note, but an import showing only km/h should not be assumed compliant without checking its approval status.

Digital clusters can sometimes be reconfigured; analogue imports may require a replacement face or instrument. The modification should be accurate and permanently legible.

An NI vehicle import normally has four separate tracks: customs/VAT with HMRC, construction or type approval, DVLA registration/tax, and DVA roadworthiness testing. Completing one does not automatically complete the others. A NOVA reference is not an MOT; an MOT is not type approval; and an IVA certificate does not itself register or tax the vehicle. The practical result is that for NI road use and testing, the speedometer must provide the required miles-per-hour indication; DfI guidance for vehicles first used from the relevant date also expects mph and km/h unless an approval exception applies. That prevents a rule written for Great Britain or the Republic of Ireland being applied automatically to a Northern Ireland case.

Imported speedometers used in Northern Ireland must display mph in the form required by the applicable DfI test or approval standard.
