What SmartWay Can Do For You:
Idling Reduction

We all know that it is common for drivers to run their engines to stay warm or cool in their trucks while resting after long hauls. And, of course, driver comfort is essential to the job.

Yet, long-duration idling is costly—to the driver, the fleet owner, and the environment. Some surveys say that trucks idle anywhere from 6-8 hours a day for as many as 250 to 300 days each year. And at current fuel prices, this can cost $6000 or more per year in fuel costs per truck.

Each year, long-duration idling of truck and locomotive engines consumes over 1 billion gallons of diesel fuel and emits 11 million tons of carbon dioxide, 200,000 tons of oxides of nitrogen, and 5,000 tons of particulate matter into the air. Also, idling can increase engine maintenance costs, shorten engine life, adversely affect driver well-being, and create elevated noise levels.

However, alternatives to long-duration idling do exist.

Take a closer look at some of the benefits, technologies, and strategies:
