Mulhuddart (N3)
The original Mulhuddart site, serving west Dublin: Castleknock, Ongar, Blanchardstown and the surrounding areas.
Test centre guide
Yes, centres. Mulhuddart has two separate test sites, and mixing them up on test morning is a real disaster that keeps happening. Here's how the two sites work, what the west Dublin routes are like, and how to arrive having driven every road type the examiner can choose. Two of our instructors work these roads daily.

The two-site trap
This catches people every week, so it goes at the top.
The original Mulhuddart site, serving west Dublin: Castleknock, Ongar, Blanchardstown and the surrounding areas.
The second site, in Rosemount Business Park. Similar suburban roads and roundabouts, but a different building at a different address.
Read the exact address on your RSA confirmation and do a trial run to it before test day. Arriving at the wrong site eats your slot. And the two sites run separate queues, so the wait at one is not the wait at the other.
The N3 site and Maple House report their waiting times separately, and the gap between them runs to weeks rather than days. You don't get to pick: the RSA assigns the site, so plan around the longer of the two. Both figures, updated every month, are on our waiting times page.

What to expect
The RSA doesn't publish routes, but they're consistent, and these are the roads our two local instructors teach on every day.
Routes run through the newer suburban network around Ongar, Castleknock and Blanchardstown, with modern road design and generally less congestion than city-centre test areas.
West Dublin's large modern roundabouts feature heavily. Their layouts are consistent and learnable, which makes roundabout lane discipline the highest-return thing to practise for this centre.
Dual-carriageway sections require confident speed management. Hesitancy at speed reads as a progress fault. If your practice has all been in estates, fix that before test day.
If you learn with us in Mulhuddart, Blanchardstown, Clonsilla or Ongar, you're on potential test roads from lesson one. By test day, nothing the examiner picks will be new to you.

It comes down to capacity. West Dublin is one of the busiest testing areas in the country, so the RSA operates two sites: the N3 centre and Maple House in Rosemount Business Park. They're separate addresses running separate queues, and you don't pick between them: the RSA assigns the site. Always check your confirmation for which one you're in.
They're similar in character: the same newer suburban network, big roundabouts and dual-carriageway sections. But they're not identical. Preparation that covers the area's road types serves you at either site; tell us which site you're booked into and we'll shape your final sessions accordingly.
They report separate waiting times, and the two figures usually differ by weeks rather than days. You can't choose between them, though: the RSA assigns the site, so plan around the longer one. The current figure for each is on our waiting times page. Remember what it counts, too: the wait to be invited to book, not the wait to test day.
West Dublin broadly: Mulhuddart, Blanchardstown, Castleknock, Ongar, Clonsilla, Tyrrelstown, Clonee and surrounding areas. Some learners from Meath commuter towns also book here when availability is better than Navan.
Prepared learners tend to like it: newer roads, predictable roundabout layouts and less congestion than city-centre areas. Its demands are specific: roundabout lane discipline and confident dual-carriageway speed. Both are very trainable.
Yes. The RSA doesn't publish routes, but they're consistent and Tudor and Liam work these roads daily. A mock test runs under examiner conditions on the road types and junctions that regularly appear, with RSA-style marking and a full debrief.
Possibly. The RSA has a new test centre at the Springfield Hotel on the Leixlip Road (R148), beside junction 5 of the M4, with tests from 1 September 2026. The RSA has confirmed that switching centre keeps your application's eligibility date. Details in our Leixlip test centre guide.
