## Pavement Markings 

Yellow lines separate travel lanes moving in opposite directions. White lines separate travel lanes moving in the same direction. A yellow skipped or broken line is used as the center line on a two-lane, two-way road where passing with care is permitted in both directions. When continuous, double, solid, yellow lines are the center lines, you cannot cross them to pass in either direction. On a two-lane road, passing with care is permitted if the skipped-yellow line is in your lane. 

Single, solid, white lines are used as right-edge lines along the roadway and for guiding traffic traveling in the same direction. Single, solid, yellow lines are used as left-edge lines on divided highways. If you see the reverse, you are traveling in the wrong direction. On certain multi-lane highways, a special

center lane is reserved exclusively for two-way left-turn movements in both directions. The two-way left-turn lane must not be used for passing another vehicle or for the purpose of merging into traffic. The marking for this type of lane is shown by the diagram below. 

White and yellow pavement “markers” are reflective devices used in the pavement to improve the visibility of marking lines at night when the road is wet. Red markers indicate wrong-way movements for motorists. In some areas, blue reflective pavement markers on roadways indicate the location of nearby fire hydrants or water supplies for fire-fighting units. 

## Traffic Officers 

Under special circumstances, an officer may be directing the flow of traffic. If so, obey the officer’s hand signals instead of the normal traffic signals or signs. Most traffic officers signal drivers to stop by holding up one hand with the palm facing the vehicle and giving a long blast on the whistle. The officer signals drivers to start or to keep moving by motioning with the hand and giving a series of short blasts on the whistle. At night, the traffic officer may signal by using a flashlight.
