Except in cases of immediate danger, the use of sound signals (horns) are prohibited in most inner city areas.

The statement is accurate because it reflects the regulations typically in place regarding the use of sound signals, such as horns, in urban environments. In inner city areas, noise pollution can be a significant issue, and excessive use of horns can lead to disturbances for residents and businesses. The prohibition, except in cases of immediate danger, reinforces the importance of maintaining a peaceful environment and only using horns when it's crucial for safety reasons, such as avoiding an accident. This regulation is often part of broader traffic control measures aimed at improving urban livability and ensuring that sound levels remain suitable for community well-being.
