Right turns only
UPS trucks don’t turn left. It’s not that they can’t, it’s just that they won’t…generally speaking.
In 2004, after evaluating their CO2 emissions, UPS announced that its drivers would avoid making left turns. They calculated that the amount of time spent idling waiting to make a left turn would save millions of dollars in fuel costs every year. For example, in 2006 UPS trucks drove 2.5 billion miles, and with their unique package flow technology combined with their right-turn routes, they estimate saving 28,541,472 million miles, and three million gallons of fuel. Talk about improving the bottom line!
