1.0 SUBJECT TITLE: Non-Revenue Vehicle Anti-Idling Policy


2.1 To protect public health and improve the environment by reducing emissions while conserving fuel. Less idling time is good for the environment because it reduces air pollution, noise and fuel use. It also reduces wear and tear on engines, lengthens engine life, saves money and contributes to a cleaner atmosphere. Reducing idling makes good business sense.
