The 'U-turn Prohibited' sign (332) is a common prohibition sign used in Iceland to indicate that making a U-turn is not allowed. This restriction typically begins at the sign itself and continues until it is cancelled by another sign or naturally ends at a junction. Drivers must immediately adhere to this rule and should be mindful of any supplementary plates that might specify exceptions or limit the scope of the ban. Always look for end signs or junction changes that might revoke the prohibition.
This sign specifically prohibits u-turns, a crucial detail for your Icelandic theory test revision. Proper understanding of this traffic sign explanation is vital for safe navigation and avoiding penalties on Icelandic roads.
U-turn Prohibited is a restrictive sign that removes a movement, access right, or operating condition that would otherwise be possible. It is used to manage safety, protect vulnerable users, reduce conflict, or keep unsuitable vehicles and behaviour out of a particular road environment. The restriction usually starts at the sign itself and continues until it is cancelled, replaced, or naturally ends according to the road-sign rules. Whenever a supplementary plate is present, it tells you exactly which vehicles, times, distances, or conditions the ban covers.
This sign prohibits or restricts u-turn prohibited from the point where it applies. Drivers must obey the restriction immediately and look for any supplementary plate or end sign that explains the scope, duration, or exceptions.
Get clear, practical answers to the most common questions about the 332 - U-turn Prohibited 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 Icelandic driving theory exam in Iceland.
The U-turn Prohibited sign (332) means that drivers are forbidden from making a U-turn manoeuvre at or from the point where the sign is displayed. You must find an alternative route or perform the U-turn at a permitted location.
Unless a supplementary plate indicates otherwise (e.g., a distance, specific times, or vehicle types), the prohibition on U-turns typically applies from the sign onwards until it is cancelled by an end sign or naturally ends at the next junction or intersection where different rules apply.
Common mistakes include assuming the U-turn is allowed if the road appears empty, forgetting to check for supplementary plates that might qualify the restriction, or attempting the U-turn and then trying to correct the mistake, which can be dangerous and is an exam trap.
You can only make a U-turn if a supplementary plate attached to the sign explicitly allows it under certain conditions (e.g., for specific vehicle types, at certain times, or after a specified distance). Always read supplementary plates carefully as they modify the main sign's instruction.
If you see the U-turn Prohibited sign (332) and need to make a U-turn, you must continue on your current path. Look for the next safe and legal place to turn around, such as a junction or a place where U-turns are explicitly permitted.
