Where Will You See the Divided Highway Begins Sign?The Divided Highway Begins sign is installed on an undivided highway to alert you that the highway ahead will be physically divided by a barrier or median strip. You are, in other words, approaching a roadway with one-way traffic. Make sure you enter the roadway to the right of the barrier or median. You should make sure you can tell the difference between Divided Highway Begins and the Divided Highway Ends signs. They are often mixed up when people take their driver’s license or learner’s permit exam. When you travel on a divided highway, there will be a solid yellow line next to the median on your left and white edge markings on your right. If the yellow line is on your right, you are going in the wrong direction against traffic.
CrossoversState laws usually prohibits crossing an unpaved median to turn around and go in the opposite direction (making a U-turn), unless an opening has been provided for this purpose. Such an opening is often marked with a green “Crossover” sign.
Lane Use on a Divided HighwayIf you travel slower than the rest of traffic, you should always keep to the right of a divided highway with multiple lanes. Use the left lane for passing or when you plan to exit or turn left ahead.
