On a Kansas highway outside city limits with two lanes going your direction, you are in the left lane but are not passing or preparing to turn left. What should you do?
Correct answer: D – Move into the right lane when the change can be made safely
On such a highway, vehicles must normally use the right lane unless passing, preparing for a proper left turn, following a traffic-control device, or complying with another law. Before changing lanes, the driver must first determine that the movement can be made safely. Do not use the shoulder as a travel lane.
