Mr Skeptic Posted February 17, 2011 Share Posted February 17, 2011 Yes. Left turns take longer, because you cannot turn on red and there is one more lane of cars you have to wait for. So long as you have enough separate places to go, you won't have to go around the block to turn left via this method. You, however, are not a UPS driver.

SMF Posted February 17, 2011 Share Posted February 17, 2011 The article that you linked says that the UPS programs the routes of their drivers for efficiency and maximizing right turns is more efficient than left turns. This is because left turns require more time waiting for a gap in oncoming traffic or a traffic signal to change than right turns. This is, of course, only true in countries that drive on the right side of the roadway. SM Link to comment Share on other sites More sharing options...
