In a recent article at ABC News, UPS informs the public that they try to avoid making left turns on deliver routes. In fact, they turn right up to 90% of the time. In a study they did in 2004, they found that lots of fuel is wasted while idling at lights waiting to turn left. Now in their company operating policy, they are encouraged to take only right turns on delivery routes. Their fleet of 93,637 cars, vans, tractors and motorcycles are estimated to save an astounding three million gallons of gas a year.
