2. To develop an orderly visual search pattern.
3. To choose a safe speed.
4. To identi$ signs, signals, and pavement markings.
5. To interact with other drivers in a light driving environment.

Analyzing Situations
Use good seeing habits - continually identi$ to the fron! rear and sides.
Select what you need to see - other vehicles, pedestrians, animals, road signs, pavement
markings, traffic lights, etc.
Identiff early - give yourself time to anallze and adjust without sudden movements.

Choosing a Safe Spced
Drive at a speed that is reasonable forthe conditions at the time and place you are driving.
Conditions to consider are roadway cherecteristics (hills, curves, width of lanes, surface,
etc.) and any weather that reduces traction, visibility, or both (rain, snow, ice, fog, etc.) and
yorl the driver (physical condition, experience, etc.). Remember that the speed limit posted
is the recornmended safe speed unde.r ideal driving conditions.
Tip: The posted speed limit mry not always be the safest speed!

TrafEc Signels
Traffic lights, arro\ils, flashing signals, lane signals, and pedesfiian signals are used to help
traffic flow smoothly. All traffic signals have qpecific colors. Red means stop. Yellow
means caution: be ready to stop. Green means go: proceed if the way is clear and safe.
"-, TrafiEc Lights
Green Light Proceed only ifthe intersestion is clear. Approaching a green light, check
traffic to the teft, front, and right before entering the intersection. When approaching a light
that has been green for some time, be prepared for the light to turn yellow.
Yellow Lig[t Make every effort to stop safely for a yellow light. If you are too close to the
intersection to stop safely when a yellow lights appears proceed with caution.
Red Light You must come to afull stop at ared ligbt. Stop behind the stop line, crosswalk,
or before entering the intersection if no stop lines are used.
Flashing Signals A flastring signal alerts drivers to dangerous conditions or tells them to
stop. These signals are used at intersections and other dangerous locations. Make a full stop
when you come to a flashing red signal. A stop sign and stop line may be used with this
signal. After you stop, yield to traffic, and proceed only when the intersection is clear.
When you see a waming sign and a flashing yellow signal, slow down. Be prepared to stop
at the traffic light.
Arrows Traffic must flow in the direction that a green arrow is pointing. If you are driving
in a lane with a geen arrow pointing to the left or right" you must tum in that direction.
Remember first to yield to other traffic and pedestrians.
Lene Siguats There are times ufuen traffic in some lanes need to go in one direction for a
certain period of time and in the opposite direction at another period of time. The direction
of these lanes is reversed on some streets and expressways to control moming and evening
nrsh-hour traffic. In these situations, lights hangrng overhead show whether or not a lane can
be used at that time. Each light is a lane signal.
Pedestrian Signats A pedestrian signal is used at an intersection with heavy traffic. These
signals or slm.bols are mounted neartraffic ligbts. Pedestians should only cross at an
intersection when they face a walk signal or symbol.
Tip: You must obey signals given by a police oficer, even if the offcer's signols
contradict the trffic sigrul.

Roadway Markings
A roadway marking gives you a warning or direction. These markings are usually lines,
words, or arrows painted yellow or white on the roadway.
MarkingsYellow Line A broken yellow line separates two-way traffc. It also means
a driver may pass only when no taffic is coming from the opposite direction.
A solid yellow line on tle driver's side of the center line indicates ttrat passing is not allowed.
Turning left across a solid yellow line into a driveway or alley is allowed after yielding to
oncoming traffic.
Two solid yellow lines that divide traffic prohibit passing that involves crossing the solid
lines.
MarkingsWhite Line Broken white lines separate lanes oftraffrc that are moving in
the same direction. You may cross these broken white lines wtrile changing lanes.
Solid white lane lines keep drivers in their lanes and restict lane changing. Solid white lines
indicate that you should not cross them.
White arows are painted in lanes to tell you when and where to turn. If you are in a lane
with an arrow and the word, ONLY, you must continue in the direction of the arrow.
Solid white lines are used along the side of a roadway. These lines help you to see the edge
of the roadway at night or underpoor visibility driving conditions.
Solid white lines are also used to mark pedestrian crosswalks and stop lines.

tr4. the left-front, front, and right-front
n5. zones.
n6. Look for line-of-sight restrictions
D7. ifthat will prevent you from seeing
tr8. your intended path of tavel will be
safe. Search for changes in the
zones.
When you are within 4to 6 seconds
of the intersection, widen your
searching pattem to include more
information from the right and left
of your path of travel. If you front
zone is clear, keep moving. If not,
prepare to stop or change your path
of travel.
When you identiff a line-of-sight
res:triction, perform a search of that
area. Tum your head 45 degrees to
the right or left to see beyond the
line-of-sight restriction. Briefly
pause at each zone to detect objects
in that location.
Continue ahead if the traffic light is
green, or if the intersection has no
signals or signs, and the front, right-
front, and left-front zones are open.
If your path of travel is clear,
continue searching the left-front,
front, and right-front zones for a
path of tavel change or line-of-sight
restriction.
Once you have passed the point-of-
no-return (the point beyond which
you can no longer stop safely
without entering the intersection),
continue through the intersection.

,_ Establishing a Safe X'ollowing Distance
'- You need to maintain a safe space cushion between your vehicle and possible hazards in all
, driving environments. Managng the qpace cushion, or distance, between your vehicle and the
_ vehicle ahead is the first step.
- An adequate following distance has these advantages:
,_ o You can see firrther ahead to get the "big picture."
o Others can see you better.
_ o You have more time to use the IPDE Process.
o You are in a better position to avoid the vehicle ahead if it stops suddenly.
,_
How to CheckYour X'ollowing Distance
Keep at least a 2 second interval between your vehicle and the vehicle ahead.
To check this time interval, follow the steps below:
1. Pick a fixed object - in the example, the tee on the right.
2. As the vehicle ahead passes the object count "one thousand and one, one thousand
and two."
3. If it for the front of your vehicle to reach your object
