The sign may be circular, rectangular, or lane-specific depending on whether it gives a mandatory instruction, restriction, prohibition, or traffic-control rule. In theory practice, focus on the exact action required and check whether any supplementary plate limits the rule by time, direction, vehicle type, or distance.

Get clear, practical answers to the most common questions about the RUS-017 - No U-Turn road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations. This FAQ strengthens your understanding and supports accurate decision making for the Irish driving theory exam in Ireland.
The primary meaning of the No U-Turn (RUS-017) sign is a prohibition. It legally instructs drivers that they must not execute a U-turn at or after the point where this sign is displayed. This restriction is binding and must be followed to ensure traffic flow and safety.
No, the No U-Turn (RUS-017) sign creates a legal prohibition. Even if there is no immediate traffic, you must not make a U-turn because the sign indicates it is not permitted at that location. Safety and adherence to traffic rules are paramount.
Generally, regulatory signs like the No U-Turn (RUS-017) sign have no exceptions unless indicated by a supplementary plate attached to the sign, a specific road marking, or a direction from a Garda (police officer). Always look for these if you are unsure, but assume the prohibition is absolute otherwise.
A common mistake is assuming a U-turn is allowed if it's not explicitly signed as prohibited everywhere. Learners might also miss supplementary plates that could alter the restriction, or they might simply forget the sign's meaning under pressure. Always treat regulatory signs as absolute instructions for the theory test.
If you have already passed the sign and are committed to a manoeuvre that is about to become a U-turn, assess the traffic situation safely. If it's safe and you can avoid completing the U-turn without causing danger, do so. If you have already begun the prohibited manoeuvre, try to complete it safely without obstructing traffic, but be aware that you have breached the regulation.
