In the midlands, people could be waiting almost five months.
The wait times for NCTs are "completely unacceptable".
That's according to Junior Transport Minister, Jack Chambers, who believes the situation is causing "enormous frustration".
In the midlands, test centres in Portlaoise, Tullamore and Mullingar have a wait time of almost five months, with their next available test dates in January.
In the region only Athlone has a slots available at the end of this month.
Minister Chambers is encouraging people to get in touch with the NCT service directly:
