Section 2.1 Traffic Signs

Stop Signs

Used on a road that crosses a main highway or a through street.

You must yield to pedestrians or other vehicles in or approaching the intersection.

4-Way Stop Signs

Driver who stops first
If two stop at the same time, the driver on the left should yield to the driver on the right.
When stopped across the intersection facing oncoming traffic, the driver going straight should be allowed to proceed. A driver turning left should wait.

Section 2.1 Traffic Signs

Yield Signs
A Yield sign may be warranted:
on a minor road at the entrance to an intersection where it is necessary to assign right-of-way to the major road, but where a stop is not necessary at all times, and where the safe approach speed on the minor road exceeds 10 miles per hour;
on the entrance ramp to an expressway where an acceleration lane is not provided;
within an intersection with a divided highway, where a STOP sign is present at the entrance to the first roadway and further control is necessary to the entrance to the second roadway;
where there is a separate or channeled right-turn lane, without an adequate acceleration lane;
at any intersection where a special problem exists and where an engineering study indicates the problem to be susceptible to correction by use of the yield sign

Section 2.1 Traffic Signs

Speed Limit Signs

A speed limit is the maximum speed allowed by local law for any road vehicles. Speed limits are commonly set and enforced by the local (town/village) or state governments.
In addition to setting a maximum speed limit, most governments also enforce speed limits which are relative to the driving conditions experienced; that is, drivers should adjust their maximum speed when driving in fog, rain, snow, or other similar conditions.
Some roads also have "minimum speed limits",
where slow speeds are considered to impede
traffic flow or be dangerous.

2.2 Traffic Signals

Traffic Lights

A traffic light, also known as a traffic signal, stop light, traffic lamp, stop-and-go lights, is a signaling device positioned at a road intersection, pedestrian crossing, or other location in order to indicate which specific movement to drive, ride or walk is assigned the right-of-way at a given moment, using a universal color code (and a precise sequence, for those that are color blind).

Traffic lights normally have two main lights—a red light that means stop and a green light that means go. In most countries there is also a yellow light, which when on by itself and not flashing means stop if able to do so safely.
In some systems, a flashing amber means that a

motorist may go ahead with care if the road is

clear, giving way to pedestrians and to other road

vehicles that may have priority.

A flashing red is treated as a regular stop sign.

ARROWS: After yielding the right-of-way to traffic within the intersection or crosswalk, you may go in the direction the arrow is pointing.
–RED ARROW: The red arrow means do not make the movement shown by the arrow until a green arrow appears. You may make a right turn at a red arrow or a left turn at a red arrow when turning from a one-way street onto another one-way street that has traffic moving to the left. In both instances, drivers must come to a complete stop and yield the right-of-way to oncoming traffic and pedestrians before proceeding.��–YELLOW ARROW: The yellow arrow means the green arrow
is ending or that the light is about to turn red.��–GREEN ARROW: When the arrow is pointed upward you
may go straight ahead only. When the arrow is pointed to the
right you may turn to the right. When the arrow is pointed to the
left you may turn to the left.

2.3 Roadway Markings

Pavement Markings

Lines and symbols are used on a roadway to warn and direct drivers and to control traffic.
EDGE LINES: Solid lines along the side of the road that tell you where the edge of the pavement is.
Solid white lines are used on the right of the roadway edge.
Solid yellow lines are used on the left edge of divided streets or roadways.
WHITE LANE LINES: White lane lines separate lanes of traffic moving in the same direction.
Broken white lines separate lanes of traffic moving in the same direction. Crossing the line is allowed only when changing lanes or turning.
Solid white lines separate lanes of traffic moving in the same direction. Crossing a solid white line requires special care and is discouraged.

2.3 Roadway Markings

Yellow Line Markings

YELLOW CENTER LINES: Yellow center lines separate lanes of traffic moving in opposite directions.

BROKEN YELLOW LINES separate single lanes of traffic moving in opposite directions. Passing is allowed

SOLID DOUBLE YELLOW LINES are used where there are four or more lanes with traffic moving in opposite directions. Two solid lines mark the center of the roadway. Solid yellow lines may be crossed to make a left turn to or from an alley, private road, driveway or street.

More Yellow Markings

YELLOW "NO PASSING" LINES: "No Passing" lines are solid yellow lines on roads where traffic moves in opposite directions. The lines indicate zones where passing is not allowed. ��When the solid yellow line is on your side of the center line, you may cross it to finish passing a vehicle you started to pass before the beginning of the no passing zone.
Or, you may cross it to make a left turn

into or from an alley, private road or driveway.

When there is a solid and a broken yellow

line separating two lanes of traffic moving

in opposite directions, you may pass only

when the broken yellow line is nearest

your lane.

More Yellow Markings

TWO-WAY LEFT TURN LANES: Two-way left turn lanes are marked with yellow lines and white arrows. A left turn may not be made from any other lane when a turn lane is provided. The turn lane is used for making turns from or into the roadway or when making a U-turn when permitted by law.

Other Markings

Yellow or white diagonal stripes are used to mark fixed obstructions.
Solid white or yellow lines are sometimes used to channel traffic around a hazard.
A double solid white line prohibits lane changing.
Curb markings, fire lanes and pavement markings may be designated as “No Parking” areas by local authorities.
In front of railroad crossings, the pavement may be marked with a large X and two R’s. A yellow line in advance of the crossing means no passing. White lines on each side of the track show motorists where to stop when a train is approaching.
