The TT-30 sign specifically prohibits drivers from using their vehicle's horn or any other audible warning device. This applies from the point where the sign is placed until an 'end of restriction' sign is encountered or another sign modifies the rule.
This sign is typically used in sensitive areas where noise pollution could be a significant issue, such as hospitals, residential areas at night, or near schools during class hours. Its purpose is to maintain peace and quiet and reduce disturbance.
Upon seeing the TT-30 sign, you must refrain from using your horn entirely. This means no short beeps to alert others or express impatience. Always check for supplementary plates that might specify exceptions, such as certain vehicle types or times of day.
Generally, no. However, supplementary plates (if present) can modify the restriction by indicating specific vehicle types, times, or conditions where the rule might not apply or might be altered. Always read any accompanying plates carefully.
A common trap is assuming the rule only applies when you *feel* it's noisy. The TT-30 sign is a direct prohibition, regardless of your perception of noise levels. Another mistake is not checking supplementary plates, which can change the scope of the restriction.
While the sign explicitly prohibits using the horn, Turkish traffic law, like most, still allows the use of a horn in situations where it is absolutely necessary for immediate safety to prevent an accident. However, the TT-30 sign makes general, non-emergency honking strictly forbidden.
