** SLOWER TRAFFIC USE TURNOUTS: Special "turnout" areas are sometimes marked on two-lane roads. You should pull to the side in these areas and allow cars behind you to pass. Other two-lane roads sometimes have "passing lanes." If you are driving slowly on a two-lane highway or road where passing is unsafe, and five or more vehicles are following you, pull to the side of the road wherever you can safely do so to let the vehicles pass.
