The unnecessary idling of diesel engines is a significant source of harmful air pollutants, including nitrogen oxides (NOx), which leads to ozone formation, and particulate matter. Extended idling of certain heavy-duty diesel engines is also prohibited by Locally Enforced Idling Restrictions. The reduction of unnecessary idling from diesel engines is one of the many strategies approved by the Regional Transportation Council to improve air quality in the North Central Texas region. Grant funds are offered periodically to assist owners of heavy-duty diesel vehicles with the purchase of idle reduction technology which can reduce emissions, fuel consumption, and operating costs, and also help drivers comply with anti-idling regulations.
