Pavement Markings and Object Markers Interacting with Signs
Pavement Markings and Object Markers work with signs to organize traffic, mark stopping points, and identify hazards. This domain tests whether you can read lane lines, stop bars, crosswalks, and object markers together with the signs nearby.
Core rules and concepts
- Yellow center lines separate traffic moving in opposite directions. A solid yellow line on your side means do not cross to pass; a broken yellow on your side permits passing when safe.
- White lines separate traffic moving in the same direction or mark the edge of the roadway. A solid white line discourages lane changes; a dashed white line permits them when safe.
- A white stop bar shows where to stop for a stop sign, signal, or crosswalk. Stop before the bar, not on it.
- Crosswalk markings guide pedestrians and alert drivers; the sign and the markings should be read together.
- Object markers, such as yellow-and-black striped hazard markers, mark obstructions near the roadway. Delineators mark the edge or alignment. Barricades close a route.
- A sign may repeat or supplement a marking; the more restrictive message controls.
Worked example
You approach a two-way road with a double yellow center line. The line on your side is broken, while the line on the opposite side is solid. You may cross the broken line to pass when safe, because the broken line is on your side. If your side were solid, you would not cross to pass, even if the opposite side were broken.
Traps
Do not cross a solid yellow line on your side just because the other side is broken. Do not stop past a stop bar or on a crosswalk. Do not treat a worn marking as absent; look for the accompanying sign. Do not drive around a barricade or object marker that closes your lane.
