J-turns are used to decrease fatalities and injuries caused by broadside crashes on four-lane divided highways. At a J-turn, drivers on the side street approaching the divided highway always make a right turn. To cross the highway or make a left turn from the side street: Come to a complete stop. Turn right onto the highway. Enter the designated left-turn lane that leads to the median opening and complete a U-turn.
