What is a common reason for enforcing idling laws on buses?

Enforcing idling laws on buses is primarily aimed at decreasing emissions. When buses remain idle for extended periods, they produce unnecessary exhaust fumes that contribute to air pollution. By limiting idling time, transportation authorities can effectively lower the amount of harmful pollutants released into the atmosphere, thus promoting a cleaner environment and improving air quality.

This approach not only targets environmental concerns but also aligns with broader initiatives to combat climate change and promote sustainable practices within urban settings. Reducing emissions can lead to better health outcomes for the community, as cleaner air directly impacts public health by reducing respiratory problems and other pollution-related issues.
