Signs, Signals, And Road Markings Page 3


  •  While driving with your family or friends you have probably noticed lines, arrows, and words painted on the streets and highways. 
  • These markings give drivers and pedestrians important information, direction, and warnings about roadway travel. 
  • You need to understand pavement markings in order to control and reduce risk.

Yellow Lines

  • Traffic that is traveling in opposite directions on a roadway is separated by a yellow line.
  • These may be single or double, solid or broken.
  • On divided highways a single, solid yellow line marks the left edge of the roadway.
  • A solid yellow line on your left means you may not pass.
  • A broken yellow line on your left means you may cross it to pass another vehicle when it is safe to do so.
  • A solid yellow line next to a broken yellow line: If the solid line is on your side you may not pass. If the broken line is on your side you may pass if it is safe to do so.
  • A double solid lines on a two lane roadway means that you may not pass in either direction. You may, however, turn left across them to turn into a driveway.
  • Two sets of solid double lines on a four-way highways stands for a solid wall.  You cannot drive on or over two sets of solid double yellow lines.  You cannot make a left turn or a u-turn across them.  You can only cross at plainly marked openings.

White Lines

  • White lines that are parallel to the roadway mark the lanes for traffic moving in the same direction. 
  • The broken white lines indicate that you may change lanes or pass if it is safe. 
  •  A solid white line has many uses. Be very careful when crossing a solid white line. 
  • A solid white edge line marks a breakdown lane.  You should not travel in a lane specified for cars that have broken down and are in need of repair.
  • Solid white lines are used to indicate the right side of the roadway.  These lines are especially helpful at night because they mark the outside edges of the road, which are otherwise hard to see.  A solid white line may also mark a bicycle or breakdown lane on the right side of the roadway.
  • Lines with Arrows: Many streets have signs painted on the road that indicate what each of the lanes are to be used for.

Curb Markings

  • A color painted curb means that you must follow special parking rules. The painted curb indicates that parking is controlled, permitted, restricted or not permitted.
  •     RED  No stopping, standing or parking at any time whatsoever.  Red curbs are designated for fire or emergency vehicles only.
  •     WHITE  White curbs are for dropping off passengers or mail, or making very quick stops.
  •     BLUE  Blue curbs and marked parking spaces are for disabled only.  In order to park in a blue zone the driver must display a placard on their rear view mirror, or their license plate must be specially marked.
  •     YELLOW  Yellow marked curbs are for loading or unloading passengers or freight.  You may not park longer than local ordinances allow. Drivers of non commercial vehicles are sometimes required to remain in their vehicles.
  •     GREEN  Green curbs are for parking for a limited time.  Usually, the time is posted next to or near the green zone, or is painted on the curb.
  • Parking placement is established by the local authorities, local business owners, and concerned citizens.
  • When parking alongside a curb, the front and back wheels that are closest to the curb should be within 18 inches of the curb. 
  • You should never park at the end of a curb, as this is usually a driveway, intersection, or crossing.  Cars that are turning can't see the driveway, or crossing traffic, clearly.
  • Don't "double park".  Not only is double parking illegal, it's also unsafe and inconsiderate. 
  • You must never park in an intersection, crosswalk on sidewalk, or within 15 feet of a fire hydrant or a fire station driveway. 
  • You may never park within 3 feet of a sidewalk ramp for the disabled.
  • Never park on the freeway, unless you are having an emergency.

Other Pavement Markings

  •   Stop lines  White lines which are a foot or more wide, and which are painted across lanes of traffic, mean that the driver must stop their vehicle behind that line. This keeps the vehicle out of the intersection and out of the way of pedestrians in the cross walk. 
  • These wide white lines are called "limit lines".
  •   Crosswalks  Every intersection where streets with sidewalks meet "at about right angles" has a crosswalk for pedestrians and bicyclists to cross the street.  The crosswalk is that part of the pavement where the sidewalk lines would extend across the street.  Many pedestrian crosswalks are marked by solid yellow or white lines.  Some crossings, especially in residential areas are not marked.
  •   Railroad crossings At the crossing there may be in place a stop sign or a traffic light.  There may be yellow and black or black and white circular signs with an "X" which say "railroad crossing" on it.  Some railroad crossings are not controlled by lights, stop signs or gates.  
  •   School warnings  Yellow lights flash when school is in session and children are nearby.  A yellow pentagon shaped sign showing a person with a child that says "school xing" will be posted.  Flashing yellow lights mean a driver should be watching for, and must stop for, children and pedestrians.
