The Road Traffic (National Car Test) (Amendment) Regulations 2020 (S.I. No. 132 of 2020) provides a 4-month extension to NCT test due dates for vehicles with an NCT certificate in force on 28 March 2020 and also to vehicles with a first NCT test due during the period beginning on 28 March 2020 and ending on 31 July 2020.
If the vehicle in question had an NCT certificate in force on 28 March 2020, the 4-month extension applies regardless of whether the NCT test due date fell within the period the NCT service was suspended. Entering the car registration number on www.ncts.ie allows a vehicle owner to check their next NCT test due date.
