Where You Can Idle and Where You Can’t- Part I
These days, engine idling is on most truckers minds. Some have taken it upon themselves to save fuel while others take offense to the idea that they can’t idle their trucks at their own discretion. Truckers these days have more options than they did in the old days. More and more trucks are equipped with idling reduction technology- Auxiliary Power Units (APUs) and Fuel Operated Heaters (FOHs), for example. And, though there are flaws in its implementation, there is also the option of using Idleaire technology at some truck stops. Idleaire provides climate control and power to trucks parked in designated truck stop parking spots. There are pros and cons to all these options.
