IntroductionTraffic signs are necessary for safe and orderly
driving. We study traffic signs their shapes, colors, and purpose -
when we first learn to drive. Its always worth taking the time for
a refresher course, though. Why? Because in many cases, knowing
what a traffic sign means can save the lives of you and your
Traffic Signs: Basic ColorsThe colors of traffic signs have
different meanings, so drivers may identify them even from a
Basic Colors:Red signs generally mean that a driver must stop,
or that something is prohibited.Example: You must bring your
vehicle to a complete stop.Example: You may not enter.RED
Basic Colors:Green signs generally give directions and guidance,
including mileage to other towns, highway identification, and
information about locations and exits.Example: RV station located
here.EXITExample: Exit highway here.GREEN
Basic Colors:Yellow signs generally contain warnings that
something dangerous is coming up, so drivers should be aware and
watchful.Example: Railroad crossing ahead.Example: Deer crossing
Basic Colors:Black and white signs generally contain regulations
and instructions. The tell you what you may and may not do.Example:
You may only drive in the direction of the arrow.Example: Enter
this lane only to make a left turn, not to pass another
vehicle.BLACK & WHITE
Every Picture Tells a StoryTraffic signs are designed to be
understood by drivers with various levels of reading skill and
comprehension. Most signs contain self-explanatory pictures.
Example: Narrow bridge ahead (the picture shows a narrowing in the
road).Example: No U-turns allowed (the red slash indicates
something is not allowed).
Every Picture Tells a Story, continuedExample: Road is slippery
when wet. Slow down.Example: Two-way traffic ahead. Stay in the
right-hand lane.Example: Vehicles or loads higher than the size
shown cant fit under the underpass.
Every Picture Tells a Story, continuedExample: Slow down and be
ready to stop if another car has the right-of-way and is
coming.Example: Do not park or stop your vehicle in this place
unless you have a handicap placard or license plate.
Railroad Warning SignsRailroads may be marked by either of the
signs shown. Additionally, there may or may not be an arm that
lowers when a train approaches. If there is more than one track,
the sign will show the number of tracks at the crossing (see
picture below and to the right). Slow down as you approach the
tracks. If you see a train, NEVER try to beat it by driving across
the tracks. Stop and wait until it passes.IMPORTANT NOTE: School
buses, vehicles carrying passengers for hire, and vehicles carrying
explosives or flammable liquids must stop at all railroad
crossings. Do not honk your horn at them because they have
Pavement Markings and PassingPavement markings regulate traffic,
including showing when you may pass another vehicle.A yellow broken
line signifies two-lane, two-way traffic. Passing is permitted.
Pavement Markings and Passing, continuedA yellow solid line in
your lane signifies no passing. Since the lines are both solid,
passing is not permitted in either direction.
Pavement Markings and Passing, continuedA yellow solid/broken
line signifies no passing for traffic in the right lane (because
the solid line is in the right lane).
Pavement Markings and PassingPass only when its safeDont pass
more than one car at a timeDont exceed the speed limit when passing
Dont pass within 100 feet of an obstructed view, or if vehicles or
pedestrians might cross your path, such as the areas around
bridges, tunnels, overpasses, railroad crossings, intersections,
and crosswalksRemember . . .
Traffic SignalsRed light: Stop! You must remain stopped until
the light turns green.Yellow light: The light is about to turn red.
You must stop if you can stop safely before entering the
intersection.Green light: You may cross the intersection or turn
where allowed.IMPORTANT NOTE: Keep an eye out for drivers who run
red lights and race through intersections!
Vehicle EmblemThis emblem, while not a traffic sign, is still
important to recognize. It is used on slow-moving vehicles, such as
farm equipment and highway construction machinery traveling on
public highways at 25 MPH or less. Use caution and slow down when
you see this emblem on a vehicle, so you do not crash into it.
Signaling for a TurnIt is illegal in Oklahoma to turn without
signaling. You should signal for at least 100 feet or 1/3 of a
block before you turn.You can use your vehicles turn signals, or
you can use arm signals.
Arm Signals for TurnsUsing your vehicles turn signals is safer
than using arm signals, because the flashing turn signals are more
visible. However, if a turn signal malfunctions, arm signals may be
used. LEFT TURN: Extend your arm and hand straight out the
Arm Signals for Turns, continuedRIGHT TURN: Extend your arm and
hand straight out the window, then pointed upward from the
Arm Signals for Turns, continuedTO STOP OR SLOW DOWN: Extend
your arm and hand out the window and then pointed downward, with
the palm to the rear.
Rules for TurningSome important safety rules to remember when
making a turn are:When making a right turn from the right lane, end
your turn in the right lane of your destination street. You can
then change to another lane when its safe to do so.When making a
left turn from the left lane, end your turn in the left lane of
your destination street. You can then change to another lane when
its safe to do so.When you meet another driver at an intersection
and you both want to turn left, each should turn to the left of the
other.Always look to the left, right and in front before making a
turn, to make sure your way is clear.
