No Entry

No Entry signs appear at the prohibited entry end of one-way streets throughout urban Ireland, at exit-only points from car parks, and at junctions where entry from specific directions is prohibited.

Common locations include one-way street systems in Dublin city center (Dame Street, Nassau Street, Westmoreland Street), Cork city center, Galway's medieval streets, motorway exit slip roads, and bus-only or access-only streets.

Signs feature white horizontal bars on red circular backgrounds—the universal 'do not enter' symbol.

Placement occurs at the point where entry is prohibited, often supplemented by one-way arrow signs visible to permitted-direction traffic.

This sign absolutely prohibits vehicular entry from the direction you're approaching—you must not drive past this sign.

The prohibition typically indicates one-way streets where entry would create head-on collision risks, exit-only routes, or restricted access routes.

Emergency vehicles may disregard No Entry signs when responding to emergencies, but general traffic has no exceptions absent specific plates stating otherwise.

No Entry violations result in fixed penalties (€80, 2 penalty points) as baseline, escalating rapidly to dangerous driving (€5,000, 5 penalty points, disqualification) for wrong-way driving in one-way streets.

Head-on collisions resulting from No Entry violations establish primary liability (90-100%) against wrong-way drivers.

Motorway wrong-way driving (entering exit ramps) results in immediate dangerous driving charges.

Automated cameras at some No Entry locations detect violating vehicles and issue postal Fixed Charge Notices.

Theory test questions emphasize recognition of No Entry signs, understanding that entry is absolutely prohibited, and awareness of situations where signs appear.

Practical driving tests in urban areas always include one-way systems; examiners assess recognition of No Entry signs before attempting prohibited entries, appropriate route planning, and understanding that signs indicate wrong end of one-way streets.

Examiners immediately fail candidates who violate No Entry signs—it demonstrates dangerous lack of sign recognition.
