Series of Sharp Corners - Left

Series of Sharp Corners signs indicate extreme hazards found on Ireland's most challenging mountain passes.

These appear on hairpin sections of the Healy Pass in Kerry, the Conor Pass descent in Dingle (Ireland's highest pass), severe switchbacks on the Glengesh Pass in Donegal, tight corners on the Gap of Dunloe tourist route, and challenging sections of the Sally Gap in Wicklow.

Corners are tighter and more severe than bends, often approaching 90-degree turns requiring first gear.

Multiple extremely tight corners lie ahead, each requiring near-complete direction changes.

Unlike bends, corners approach right-angle turns.

Reduce speed to 30-40 km/h or lower before the first corner.

Use first or second gear throughout.

Each corner severely restricts visibility for the next.

You must stay strictly on your side—oncoming vehicles will be invisible until you complete each corner.

Do not attempt to accelerate between corners.

Full concentration and precise steering control are essential.

These are among Ireland's most challenging road sections.

Excessive speed through corner series results in dangerous driving charges: 5 penalty points, fines to €5,000, imprisonment, and disqualification for minimum 2 years.

Corner series have extremely high collision and fatality rates.

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

Single-vehicle crashes in marked corner series establish clear driver fault.

Insurance claims are scrutinized heavily where clear warning signs were ignored.

Recovery costs in remote mountain areas can exceed €10,000.

Learner drivers are rarely tested on extreme corner series, but understanding the distinction between bends and corners is essential for theory tests.

Corners require lower speeds than bends due to tighter turning radii.

Theory questions test knowledge that corner series demand first gear, speeds potentially below 30 km/h, and that acceleration between corners is dangerous.

Professional drivers and advanced tests specifically assess corner negotiation: approach speed reduction to 20-40 km/h, first gear selection, precise steering inputs avoiding corrections, strict lane discipline, and sustained concentration throughout the series.
