It sounds straightforward — you're already on the correct side of the road, so surely turning left is the easy one? In reality, left turns are responsible for a surprising number of faults on the Irish driving test. From cutting the corner to forgetting the cyclist in your blind spot, there's more to a safe left turn than most learners realise.
Why Left Turns Are Trickier Than They Look
In Ireland, we drive on the left, so right turns feel riskier — you cross oncoming traffic. But that sense of danger actually makes drivers more careful on right turns. Left turns feel routine, and that familiarity breeds complacency. Examiners know this, which is exactly why they pay close attention to how you handle them.
The Most Common Left-Turn Mistakes
1. Cutting the Corner
This is the classic error. As you turn left, the natural tendency is to swing slightly right first or to cut across the corner of the junction, encroaching on the path of oncoming traffic or cyclists coming straight on. Always keep as close to the left kerb as is safe throughout the turn. Your front wheels should trace a smooth arc, not a shortcut.
2. Forgetting Cyclists and Pedestrians
Before you complete a left turn, a cyclist may be travelling straight ahead on the inside of your lane — exactly where you're about to go. Check your left mirror and your left blind spot just before you turn. Equally, a pedestrian may have already stepped out to cross the road you're turning into. Give way to them; they have right of way once they've started crossing.
3. Poor Use of Mirrors and Signal
The Mirror–Signal–Mirror–Manoeuvre (MSM) routine applies just as firmly to left turns as to any other manoeuvre. Signal in good time — not so late that following traffic is surprised, but not so early that you mislead drivers near a side road before your intended turn. Check your centre mirror, then your left mirror again just before turning.
4. Speed Control
Entering a left turn too fast forces you to steer sharply, which widens your line and unsettles the car. Reduce your speed before the turn using the footbrake, then use gentle acceleration through the arc to keep the car balanced and under control.
5. Positioning on Approach
Some learners drift too far left before turning — almost hugging the kerb — making it difficult to steer smoothly. Others approach too wide, from the centre of the road. The correct position is normal driving position: about a metre from the left kerb, giving you room to steer without mounting it.
What the RSA Examiner Is Looking For
Your examiner will be watching for a complete MSM routine, appropriate speed, correct road position on approach and throughout the turn, effective observation (including that left blind-spot check), and that you yield to any pedestrians crossing. A single serious fault here — such as cutting across a cyclist's path — can end your test.
Practise on Real Test Routes
Left turns crop up constantly on every Irish driving test route, often in quick succession in town centres. One of the best ways to build confidence is to practise on the actual roads your examiner will use. SteerClear lets you preview real driving test routes for your local test centre, so you can walk (or drive) every left turn before test day and know exactly what's coming.
A Quick Pre-Turn Checklist
- Mirror–Signal–Mirror well before the junction
- Reduce speed on approach; select correct gear
- Keep normal road position — don't creep left too early
- Check left blind spot for cyclists just before turning
- Yield to pedestrians already crossing
- Steer smoothly, keeping close to the left without mounting the kerb
- Gentle acceleration through and out of the turn
Master the humble left turn and you'll remove one of the most quietly common sources of test faults. It's not glamorous, but neither is repeating your test — so give every left turn the attention it deserves.
