Core facts about Sharp Corner - Left
Sign name	Sharp Corner - Left
Sign type	Warning Signs
Expected in DTT?	Yes. This sign is commonly covered in Irish driving theory test preparation.
Action required	A tight left corner ahead requires near-complete direction change, more severe than a sharp bend. Reduce speed to 30-50 km/h and select second or first gear before entry. Corners have minimal turn radius creating very restricted forward visibility. You will not see oncoming traffic until you complete the turn. Stay strictly on your left—corner geometry makes cutting extremely tempting but dangerous. Use the limit point technique: as you turn, the point where your view is obscured should appear to move away from you at constant speed if your speed is correct.
Appearance	Triangular / Red and white
Typical location	Sharp Corner Left signs indicate hazards more severe than bends but typically singular rather than in series. Found at tight left turns on mountain roads in Kerry and Wicklow, severe curves on coastal routes in Donegal and West Cork, sharp turns on older roads in rural areas, and tight corners in villages and towns where roads follow historic layouts. These corners approach 70-90 degree turns requiring second gear or first gear at speeds of 30-50 km/h, significantly slower than sharp bends.

This page explains what the Sharp Corner - Left sign means, where it is typically found, and how drivers should respond in Ireland. It also connects you to closely related signs so you can compare similar road situations and build stronger theory-test recall.

Penalties & Legal Consequences

Excessive speed through corners results in dangerous driving charges, not careless driving, due to severe risk: 5 penalty points, fines to €5,000, imprisonment, and disqualification for minimum 2 years.

Corners have high collision rates due to drivers underestimating severity.

Cutting corners into oncoming traffic paths results in dangerous driving causing serious injury or death charges when collisions occur: up to 10 years imprisonment.

Advisory speed signs at corners are critical legal evidence in liability determinations.

Ignoring clear corner warnings results in full driver liability.

Appears in Driving Test?

Corner negotiation demonstrates fundamental vehicle control competency.

Practical test assessment requires approach speed reduction to 30-50 km/h well before the corner, gear selection (second or first) before entry, smooth steering without mid-corner corrections, strict lane discipline, and no acceleration until the corner is completed and visibility restored.

Mid-corner braking indicates poor planning and results in Grade 2 faults minimum.

Excessive speed requiring steering corrections or causing position errors results in Grade 3 failure.

Theory questions distinguish corners (tight, requiring very low speeds) from bends (less severe, higher speeds possible).
