  1. Roadway Markings NV Driver Education Curriculum Unit 2: Signs, Signals, and Roadway Markings Presentation 3 of 3

  2. Roadway Markings • Warn, regulate, and inform • lines, words, or symbols on the road • Marking are white and yellow • May be reflective • Type of lines have meaning • Solid and Broken

  3. Two Colors of Lines • White lines separate traffic lanes traveling in the same direction • Yellow lines separate traffic lanes traveling in oppositedirections General rule: Broken lines can be crossed andsolidlines cannot (exception when making a turn)

  4. Yellow Lines Yellow lines separate traffic lanes traveling in opposite directions Single, broken yellow line indicates may pass when safe Single, solid yellow line indicates that passing is not allowed

  5. Single Lane Roads Two-way traffic Yellow center line may be single, double, solid, or broken (dashed) You may pass when there is a broken line on your side of the road You may not pass when there is a solid line on your side of the road

  6. White Lines • White lines separate traffic lanes traveling in the same direction • Broken(dashed) white lines may be crossed when changing lanes • Solid white line are used in several ways, including marking edge of road. May not cross, with few exceptions: • Immediate right turns (no more than 200ft prior) • Enter or exit HOV lane

  7. Solid White Lines Video See LVPD Video Crossing Solid White Line http://www.youtube.com/watch?v=Jq3zn2TtBiA (0:31) • Click on web address to access video clips • *Suggest full screen viewing • NOTE: Some on - Check access

  8. Center Lanes Shared left-turn lane • May not be used for passing • May not travel more than 200ft before turning left • May not travel more than 50ft after turning left before merging with traffic

  9. White Arrows White arrows indicate a turn lane • If marked “ONLY” you must obey direction • When marked with a curve and straight arrow, you may turn or continue forward

  10. Reversible Lanes Reversible lanes are used to improve traffic flow during rush hours • Marked by two broken yellow lines • Changes direction of travel within lane • Overhead signals indicate availability RED “X” – Lane is closed in this direction. Never drive in this lane. YELLOW “X” – Lane signal is going to change. Exit the lane safely before the red “X” appears GREEN ARROW – Lane may be used.

  11. High-Occupancy Vehicle (HOV) Lane High-Occupancy Vehicle (HOV) lanes are restricted for vehicles with two or more people • Designed by a diamond-shape symbol • May have restricted hours

  12. HOV Lanes Video See Nevada RTC&DOT video HOV Lanes in Las Vegas http://www.youtube.com/watch?v=fFkRMfMIGk4 (2:43) • Click on web address to access video clips • *Suggest full screen viewing • NOTE: Some on - Check access

  13. Highway Ramps Highway ramps use solid white lines to indicate it is dangerous and illegal to cross • Called the gore area: area between the edge of the highway and the edge of the ramp meet • May include angled or diagonal lines

  14. Stop Lines and Crosswalks Stop lines are wide white lines where you must stop before entering an intersection or railroad crossing Crosswalks are areas for pedestrians (in front of stop lines) and may include two parallel or diagonal lines.

  15. Special Lanes Bike lanes • Designated by striping and signing • If line is broken may cross if clear • Bus lanes • Used to speed up public transport • Some cities may allow taxis • May have time designations

  16. Raised Pavement Markers Reflective Markers (may or may not be raised) like white and yellow lines - mark lanes of travel • White markers used between lanes or edge of road • Red markers warn drivers going the wrong direction • Yellow markers found on left edge of expressways • Blue markers identify the location of a fire hydrant

  17. Other Pavement Markings Rumble strips • Grooved or corrugated roadway, causes vibration and loud noise when drive over • Speed bumps and dips • Used to slow traffic speed • Should drive slowly over bumps and through dips

  18. Other Roadway Markings Lines, words, and symbols found on the pavement

  19. Did You Know • Both Michigan (1911) and California (1917) claim to be the first to develop center road lines. • White center lines were used in the U.S. until 1971, when yellow became the mandated standard. White center lines are used in Canada, Great Britain, and many other countries.
