You can book another theory test the next day, but nidirect says you cannot take it until three clear working days have passed. This tool works out the standard weekday calculation.
Important: this calculator counts Monday to Friday as working days and does not attempt to predict every Northern Ireland public/bank holiday. The DVA booking system is the final source for an available appointment.
Official basis: nidirect says another theory test can be booked the next day, but it cannot be taken for another three clear working days. Checked 21 September 2026.
