The T11 Extent sign, often called an 'Extent arrow' or 'Boundary marker', clarifies how far a primary traffic sign's regulation or restriction is in effect. Look closely at the arrows: double-headed arrows mean the rule applies on both sides of the sign, while a downward arrow indicates the regulation ends at that point. Correctly interpreting these supplementary plates is crucial for avoiding violations, especially concerning parking and stopping rules, and is a common topic in the Swedish driving theory exam.
Learn the key details of the T11 - Extent road sign, including its function, what it communicates to drivers, and how it applies in real traffic situations in Sweden. Use this overview to understand the sign clearly and recognise it confidently during the Swedish driving theory exam.
This supplementary plate uses arrows to explain how far a rule applies relative to the sign’s position. A plate with double headed arrows, placed horizontally or vertically, indicates the instruction applies on both sides of the sign. A plate with a downward arrow indicates that the instruction ends at that point. When used under the Parking sign (E19), it may appear with black symbols on a white background without a border. The same plates can also be used on their own to mark boundaries of parking bays within an area where parking is allowed at the entrance. Correct interpretation is essential for knowing exactly where a parking or stopping rule starts and ends.
Shows whether the main sign applies on both sides of the sign, or where the regulation ends.
Get clear, practical answers to the most common questions about the T11 - Extent 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 Swedish driving theory exam in Sweden.
When the T11 Extent sign shows double-headed arrows (horizontally or vertically), it means the regulation indicated by the main sign (like a parking restriction) applies on both sides of the sign. You need to consider the rule's effect extending away from the sign in both directions.
A T11 Extent sign with a single downward arrow signifies the end of the regulation or restriction set by the main sign. Once you pass this sign, the previous rule no longer applies, and you can revert to the general traffic rules or any new rule indicated further ahead.
The T11 Extent sign is frequently used with the Parking sign (E19) to define the exact area where parking is allowed or prohibited. Double arrows show the zone extends in both directions from the sign, while a downward arrow marks the end of a parking restriction zone. It can also be used independently to mark the boundaries of parking bays.
A common trap is assuming a parking or stopping restriction only applies for a short distance, or on only one side, when the T11 Extent sign with double arrows clearly indicates it applies in both directions from the sign. Another mistake is not recognizing when a downward arrow signals the end of a restriction, leading to incorrect assumptions about where it's safe to park or stop.
Yes, the T11 Extent sign can be used on its own, particularly to mark the precise boundaries of parking bays within an area where parking is permitted. In these cases, the arrows clearly show where each bay begins and ends, helping drivers position their vehicle correctly within the designated space.
