Get clear, practical answers to the most common questions about the TT-4 - No entry 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 Turkish driving theory exam in Turkey.

What does the TT-4 'No Entry' road sign specifically prohibit?

The TT-4 'No Entry' sign prohibits drivers from entering a specific road, area, or continuing a movement. This prohibition can apply to all vehicles, or it may be restricted to certain types of vehicles, directions, or situations as indicated by supplementary plates. Always assume the prohibition applies to you unless an exception is clearly stated.

When should I expect to see the TT-4 'No Entry' sign in Turkey?

You might encounter the TT-4 'No Entry' sign at the beginning of one-way streets, at junctions where entry is prohibited, or to prevent access to areas that are not suitable for general traffic. It's essential to read any accompanying plates carefully as they provide specific details about the restriction.

What should I do if I see the TT-4 'No Entry' sign and it blocks my intended route?

If the TT-4 'No Entry' sign prevents you from taking your planned route, you must not ignore it. Instead, you need to find a legal alternative route. Look for other traffic signs that guide you to a permissible path or a place where you can safely turn around or change direction.

Are there any exceptions to the 'No Entry' rule indicated by the TT-4 sign?

While the TT-4 sign generally means a strict prohibition, exceptions can be indicated on supplementary plates. These might specify that the restriction does not apply to certain vehicle types (like bicycles or emergency vehicles), during specific hours, or for particular movements like turning right. Always look for these plates to understand any potential exceptions.

What is a common mistake learners make with the 'No Entry' sign during the theory exam?

A common mistake is assuming that if other drivers ignore the sign, it's acceptable to do so as well. The TT-4 'No Entry' sign is a binding instruction, and you must obey it regardless of others' actions. Another trap is not reading supplementary plates, which can significantly alter the meaning or scope of the prohibition, leading to incorrect answers in exam questions.
