What does the TT-30 'No Audible Warning Devices' sign mean?

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.

Why would a 'No Audible Warning Devices' sign be used?

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.

What should I do if I see the TT-30 sign?

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.
