Top 10 Fail Spots in the Tallaght Driving Test
The Tallaght test centre sits in one of the busiest road networks in south Dublin. Examiners pull from a wide mix of estate roads, dual carriageways, signalised junctions, and large roundabouts, so the test can feel unpredictable. The locations below are commonly reported as fail spots by learners who sat their test out of Tallaght. Knowing them in advance, and practicing them properly, can make the difference between a pass and a second sitting.
For the full route list and what to expect on test day, see our Tallaght driving test routes guide.
1. The Belgard Road junctions
Belgard Road is a major artery near the test centre, with multiple traffic-light junctions and bus lane filters. Learners often fail here for hesitation when lights change to amber, drifting between lanes, or stopping in the yellow box at the Cookstown Way junction. Pick your lane early, commit, and only enter the box if your exit is clear.
2. The Cheeverstown roundabout (N81 / Fortunestown Lane)
This is a busy multi-lane roundabout where the N81 meets the Tallaght road network. Lane discipline is the big issue. Learners frequently take the wrong lane on approach, signal too late, or cut across a lane on exit. Read the road markings well before the give-way line and signal off as you pass the exit before yours.
3. Old Bawn Road bends and parked cars
Old Bawn Road has narrow stretches with parked cars on both sides and a steady flow of oncoming traffic. Learners commonly fail here for not yielding to oncoming vehicles when their side is obstructed, or for clipping in too close to parked cars. Hold back, make eye contact with the oncoming driver, and only proceed when the gap is clearly yours.
4. Estate roads around Kilnamanagh and Killinarden
Tallaght routes almost always include a swing through residential estates. Speed limits are 30 km/h or 50 km/h, and examiners watch for excessive speed, weak observation at unmarked crossroads, and poor positioning around parked cars. Treat every estate junction as a give-way, even when there is no sign.
5. The Cookstown Industrial Estate area
HGVs, vans reversing out, and pedestrians stepping between lorries make Cookstown a high-observation zone. Learners often fail for missing a vulnerable road user or for nervous, jerky steering when squeezing past wide vehicles. Keep your eyes scanning and your speed low enough to stop on sight.
6. The Tallaght Hospital area
Near Tallaght University Hospital you get pedestrian crossings, buses pulling out, taxis stopping, and a stream of people crossing outside marked points. Failing to anticipate a pedestrian, or rolling through a zebra crossing as someone steps off the kerb, is a common serious fault here. Cover the brake and assume someone will step out.
7. The M50 / N81 slip approaches
While your test will not take you onto the motorway, you may drive on roads that approach M50 slips with higher speeds and merging traffic. Learners commonly fail for poor mirror checks before changing lane, or for slowing down too much on a national road. Match the flow, check mirrors and blind spot, and move decisively.
8. Right turns across traffic on the Greenhills Road
Right turns at busy junctions on Greenhills Road and the N81 catch a lot of learners out. The usual mistake is creeping into the junction without a clear gap, then either stalling or rushing across. Wait for a definite gap, do not block oncoming traffic, and keep the wheels straight until you are ready to move.
9. The reverse around a corner on a quiet estate road
Examiners often pick a side road off the main estate routes for the reverse manoeuvre. Common faults include mounting the kerb, swinging too wide on the entry, or failing to check over the shoulder and into mirrors throughout. Practice this on roads of different widths, not just one familiar spot.
10. Returning to the test centre on Cookstown Way
The final stretch back to the centre lulls a lot of candidates. After 30 minutes of concentration, learners drop their observations, miss a final mirror check before the indicator goes on, or roll through the centre car park entrance without checking for pedestrians. Stay switched on until the handbrake is up and the engine is off.

Do not just read these spots, drive them. Ask whoever is supervising your practice to take you through Belgard Road, the Cheeverstown roundabout, and a couple of estate loops on different days and at different times. Tallaght traffic at 9am is a different test from Tallaght at 2pm.
The official syllabus and fault categories are available on the RSA website. Pair that with the local detail above and you give yourself a real edge on the day.
