Driving Tests & Theory
What happens if I get one serious fault on the driving test in Northern Ireland?
One serious fault is enough to fail the practical driving test.
A single serious fault causes a fail on the Northern Ireland practical driving test, even if you have very few ordinary driving faults.
The same applies to a dangerous fault.
This is why focusing only on the number of minor faults is misleading. One serious or dangerous fault is enough to fail the practical test.
Northern Ireland theory tests, practical driving tests and candidate requirements are administered by the Driver & Vehicle Agency (DVA), so current DVA/nidirect guidance should be used for bookings, documents, fees and test-day rules.
