Presentation 3 of 3
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
Two Colors of Lines
• White lines separate traffic lanes traveling in the same direction
• Yellow lines separate traffic lanes traveling in opposite directions
General rule: Broken lines can be crossed
and solidsolid lines cannot (exception when making a turn)
Yellow Lines
Yellow lines separate traffic lanes traveling in opposite directions
Single, broken yellow line indicates may pass when safe
Single, solidsolid yellow line indicates that passing is not allowed
Single Lane Roads
Two-way trafficYellow 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 solidsolid line on your
side of the road
White Lines
• White lines separate traffic lanes traveling in the same direction
• Broken (dashed) white lines may be crossed when changing lanes
• SolidSolid 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

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
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
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

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
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.
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
Raised Pavement MarkersReflective 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
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
Other Roadway MarkingsLines, words, and symbols found on the pavement
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.
