Get clear, practical answers to the most common questions about the TT-27 - No overtaking 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.
The TT-27 sign explicitly prohibits you from overtaking any other vehicle. This is a binding rule designed to prevent accidents in areas where overtaking is hazardous. You must not pass another vehicle unless a supplementary plate specifies an exemption or condition that allows it.
Upon seeing the TT-27 sign, you must immediately plan to not overtake any vehicles. If you were intending to overtake, you must abandon that intention and maintain your position behind the vehicle in front, or change lanes if safe and legal to do so without overtaking. Always check for supplementary plates which may limit the scope of the prohibition.
Generally, no. The TT-27 sign means overtaking is prohibited. However, always look for a supplementary plate beneath the main sign. This plate might restrict the prohibition to certain vehicle types, specific times, or distances, or it might specify exceptions. Without such a plate, assume overtaking is completely forbidden.
A common trap is assuming the restriction ends as soon as the sign is behind you, or assuming it doesn't apply to you because other drivers are doing so. Remember, the prohibition lasts until you see an end sign or new instructions. Also, misinterpreting supplementary plates is another frequent exam pitfall; always read them carefully.
The TT-27 sign, by default, applies to all vehicles. However, as mentioned, supplementary plates can be used to limit the prohibition to specific vehicle categories, such as heavy goods vehicles or motorcycles. If no such plate is present, you, as a driver of a passenger car, must not overtake.
The restriction indicated by the TT-27 'No Overtaking' sign remains in effect until you encounter an 'End of Prohibition' sign (often a black diagonal bar across a sign similar to the one that imposed the restriction) or another traffic sign that modifies or cancels the rule. Never assume the restriction has ended without a clear signal.
