What is Risk?
Driving Risk is the potential that a chosen action (e.g., speeding, texting, etc.,) may lead to an undesirable outcome.
Choices have Consequences
4
To properly assess a specific risk, you need to have some idea of the potential outcomes.
For example, if you are a distracted driver, your potential for being involved in a crash increases 4 to 9 times. (Children’s Hospital of Philadelphia, 2008)
Assessing and Managing Risk
5
Drivers must have the ability to:
• Identify a potentially dangerous situation• Prepare to take action to avoid a conflict• Consider your options and the potential
consequences of your actions
What is Risk Assessment?
6
Consequences of Risky Driving Behaviors
Taking unnecessary risks may result in property damage, injury or death, and other losses• Injury to you or others - permanent or life-threatening,• Damage to personal property, and • Loss such as financial loss, loss of license, loss of
convenience, loss of time, and other losses.
7
• Motor vehicle crashes are the leading cause of death for teens, accounting for more than one in three deaths in this age group
• Approximately nine teenagers, (ages 16 to 19) died every day from motor vehicle injuries
• Per mile driven, teen drivers ages 16 to 19 are four times more likely than older drivers to crash
What can YOU DO to change these statistics?
Teen Crash Statistics in the USA
8
Virginia data for 2011
• 1 crash every 4.36 minutes
• 2.09 lives lost per day because of traffic crashes
• 174 persons injured per day because of traffic crashes
• 1 out of 25.39 licensed drivers are involved in a crash
• Some drivers NEVER have a crash!
Consequences of Risk-Taking Behaviors
Young drivers take more risks than other drivers
9
Very often drivers actually create the high risk situations they become involved in! • Speeding is the number one cause of crashes in Virginia
Speeding is driving above the posted speed or driving too fast for conditions
Risk-Taking Behaviors Cause Crashes
Do speed limits improve public safety?
10
• Failure to Yield Right of Way is the second leading cause of crashes in Virginia
• Right of way is when a driver or pedestrian is allowed to proceed first at an intersection, merging roadway, private driveway, etc.
Assessing and Managing Risk
A driver cannot “take” right of way, it must be given by another driver
11
• Driving While Intoxicated is the third leading cause of crashes in Virginia
• In Virginia, 245 persons were killed in alcohol-related crashes in 2011.
Assessing and Managing Risk
Why are young drivers who consume alcohol at much greater risk of being involved in crashes?
12
Disregarding a traffic sign or signal is the fourth leading cause of crashes in Virginia
Assessing and Managing Risk
13
Following Too Closely is the fifth leading cause of crashes in Virginia. You will not crash if you have space -- space is time – time to steer or brake to avoid a hazard
Assessing and Managing Risk
Factors Contributing to Risk
Why do young drivers tend to leave shorter following distances than older drivers?
14
Other Driver Actions Contributing to Crashes• Improper Turns — Examples of improper turns would be
turning wide in a right turn or cutting corners on left turns
• Unsafe Passing — This involves illegal passing or passing without sufficient clearance
• A lack of driving experience and risk-taking
Assessing and Managing Risk
15
Factors such as worn or bald tires, poorly adjusted and/or worn brakes, broken headlights, worn windshield wiper blades, dirty windshield, etc., are all risk factors increasing the possibility of a crash
Condition of the Vehicle
16
• Road designs that restrict vision, such as intersections, hills and sharp curves
• Weather conditions, such as bright sun glare and shadows, wet slippery roads
• Road surface that affects traction, such as wet, ice, snow, gravel, dirt, etc.
Roads and the Environment
Roadway construction and maintenance
17
Assessing and Managing Risk
Risk is always present…
• Never risk more than you can afford to lose
• Do not risk a lot for a little
• Consider the odds and your situation
18
Tools to Reduce Driving Risks
1. Communicate
2. Change Speed and/or
3. Change Position
19
Communicate
Signal – lights or hand signals (turning, backing, hazards, warning)• brake light (flash, slowing, stopping)• lane position (intent to change lanes or turn,
hazard in lane ahead)• horn (warn, get someone’s attention)• head lights (to see and be seen, to warn others)
20
Change Speed
Your options are to maintain, increase or decrease speed if:• path of travel is open• path of travel is changing• path of travel is closing• path of travel is closed
21
Change Position or Direction
It is quicker to change position than to stop, so you always need to know what space is available to:• move to a different lane position to
gain more space• change lanes• turn onto another street
22
• Drivers need visibility, space, and time to avoid conflicts and perform safe driving maneuvers
• Good seeing habits and the ability to manage space on the roadway are essential ingredients for low-risk driving
• Developing space management HABITS can reduce driving risks
Assessing and Managing Risk
How Much Risk is Acceptable?

24
Safe Driving on the “Habit Level”
Practicing safe driving procedures until little thought is required to perform with skill and precision
Is it true that practice makes perfect? - No Perfect practice makes perfect!
25
What do they all have in common?
26
Do YOU Have These Good Habits?
• Plan ahead and leave early
• Prepare yourself and the vehicle
• Perform smooth gradual starts and stops
• Consistently use reference points to determine vehicle placement
• Establish visual targets in your path of travel
• When you apply your foot to the brake or accelerator, you check the rearview mirror
27
Do YOU Have These Good Habits?
• Prior to moving to the left or right, you check side view mirror
and mirror blind spot
• You always strive to maintain a four-second following interval
from the vehicle in front to create space and protect yourself to
the front and rear from unsafe actions of other drivers
• When stopped behind a vehicle, you leave space to move around
the stopped vehicle in case of an emergency or rear-end crash
28
Do YOU Have These Good Habits?
• Visually target to the end of the path of travel
• When approaching a light, you adjust speed to time your arrival to the green light or stop
• Prior to entering an intersection, you check front, left, and right zones, and back to the front and left again
• Reduce stress by being courteous rather than competitive while driving
• Minimize distractions
29
What is a Space Management System?
• A space management system helps drivers organize information into meaningful categories so decisions can be made easily and quickly
• Drivers must evaluate potential risk using the principles of probability (will it happen?) and consequence (what will be gained or lost?)
Assess, Action Step, Evaluate
30
Managing the Space Around Your Vehicle
Drivers must manage all six zones around the vehicle, and adjust position to maintain a safe margin of space that
provides room to steer in an emergency
Right-Front Zone
Right-Rear Zone
Front Zone Rear Zone
Left-Front Zone

Open, Closed and Changing Zones
• A Zone can be OPEN, CLOSED or CHANGING
• OPEN — An open zone is a space where you can drive without restriction
• CLOSED — The space or area is not available in the vehicle’s path of travel
• CHANGING — An open zone changes to a closed zone or a closed zone becomes an open zone
32
Using a Space Management System
Evaluate your options and then take action
OPEN — this zone that has no restrictions to the line of sight or path of travel.
CLOSED — this zone not available
CHANGING — it was an open zone that is changing to a closed zone.

33
Controlling Space
Drivers have the most control over the space directly in frontof the vehicle
2-Second - Following Distance is effective at speeds under 35 mph
3-Second - Following Distance may provide enough time for evasive steering maneuver on dry surfaces or to brake at speeds up to 45 mph
4-Second - Following Distance provides time to steer out of a problem on dry surfaces and brake out of a problem at speeds up to 70 mph
34
Measuring Your Following Distance
one-thousand-one one-thousand-two one-thousand-three, and…
Begin counting when rear of the vehicle ahead passes a fixed object
35
Measuring Your Following Distance
ESTABLISH FOLLOWING DISTANCE when you reach the fixed object
one-thousand-four
36
• Visibility is limited• Traction is limited• Number of visual and mental tasks increases• being tailgated• line of sight restriction• path of travel restriction• carrying a heavy load or pulling a trailer• learning to drive
Increase Following Distance When
37
Stopping Behind Another Vehicle
Why do you stop in a position that you can see the rear tires of the vehicle in front?
See tires
38
When the light turns green, does that mean you can move into the intersection?
Space Management for Intersections
39
Managing the Space to the Rear
Check rearview mirrors:• Regularly• Before and while braking• While stopped in traffic• Before and after making turns• Before and after a lane change
Can you control the space behind you?
40
• Strive to keep one of the side zones open
• Respond to an oncoming vehicle by slightly adjusting lane position to increase space between your vehicle and the oncoming vehicle
• Adjust lane position to increase space between your vehicle and parked cars, bicyclists, pedestrians, etc.
Managing the Space to the Sides
41
Judging Gaps in Traffic
In order to judge a gap you need to be able to judge speed, time and distance while moving. This is a very difficult skill for novice drivers.
• Why is a vehicle approaching from the left most hazardous?
• Why is a larger gap needed for a right turn than to cross an intersection?
• Why is a left turn more dangerous than a right turn?
42
Judging Gaps from a Stopped Position
Traffic is moving at 30 mph
• 5-6 seconds to cross a two lane roadway (vehicles need to be at least a block away)
• 7-8 seconds to cross a four lane intersection
• 7-8 seconds to turn left (vehicles need to be more than a block away or length of a football field)
• 6-7 seconds to turn right (vehicles need to be at least a block away)
• 4-6 second gap to change lanes into traffic from parked position
43
Component of a Space Management Systems
Perception/Reaction/Response Time
Perception TimeTime it takes to identify a risk
Average perception time varies with the circumstances
Reaction TimeTime it takes to respond with accelerator, brake, or steeringAverage reaction time is ¾ second

• Medications• Alcohol
• Illness• Age• Talking on Cell
Phone• Others?
• Distractions
• Inattention
• Poor Visibility
• Line of Sight Restrictions
• Fatigue
Factors Affecting Response Time
45
Calculating Speed & Distance Traveled
Formula to calculate feet per second for each MPH of speed
A vehicle will travel 1.467 (rounded up to 1.5) feet per second for each mph of speed
40 mph x 1.5 = 60 feet per second
60 mph x 1.5 = 90 feet per second
80 mph x 1.5 = 120 feet per second
46
Take the speed, divide by two, add the answer to the speed. Examples:
40 mph ÷ 2 = 20 + 40 = 60 feet per second
60 mph ÷ 2 = 30 + 60 = 90 feet per second
80 mph ÷ 2 = 40 + 80 = 120 feet per second
A football field is 300 feet in length.
Calculate how long it will take a vehicle traveling 40 mph, 50 mph, and 60 mph to cover the length of the football field.

• Search— the entire scene in your line of sight/path of travel for potential risks, and if during your search you identify a risk you
• Evaluate —it by determining if and where possible points of conflict may occur, and then
• Execute —your decision as how to best manage the risk by adjusting speed and/or position
• in Time – to avoid the conflict
Virginia Space Management System
SEEiT
49
Search in SEEiT
• Know when, where and what to look for
• Search far ahead, to the sides, to the rear
• Search for clues: intersections, brake lights, warning signs, traffic lights, other vehicles, pedestrians, animals, parked cars, etc.,
• Search for changes in front wheels of other vehicles, movement from the side, etc.
50
• Search intersections, crosswalks, shopping centers, parking lots, construction areas and playgrounds
• When driving in rural areas search for hidden intersections and driveways, curves, hills and varying road conditions
• Search for trucks and other oversized vehicles, as well as slow moving farm vehicles, motorcycles, bicycles, etc.
Search in SEEiT
51
Search
Search at least 20-30 seconds ahead to your target area which allows • time to identify and evaluate
potential problems• time to execute your plan (adjust
position, speed)
52
Is there a potential for conflict in the example below?
You are the driver of the red car traveling at 55mph. • The motorcyclist is traveling at 50mph. • The blue car is traveling at 60mph.• The search process consists of the three ranges:
- 4 to 8-second range—Immediate Action Required!- 12 to 15-second range— look for Escape Routes- 20 to 30 second range—Search for open path of travel
Searching and Time
4 to 8seconds
20 to 30seconds
12 to 15seconds
53
Evaluate
• Gives meaning to your search
• Identifies where the possible points of conflict may occur
• Determines how the conflict may affect you if it does happen
54
Evaluating Risk in the Driving Environment
• Is the traffic light a stale green light?• Will the zone I’m entering be open or closed?• What lane position is the safest?• What is the other driver going to do?• Is the driver texting?• Is there more than one way to manage this risk? • Where will the point of conflict occur?
55
• Where is the escape route?
• Will someone run the light?
• Will a pedestrian enter the roadway?
• Is there sufficient traction available?
• Is the driver in the vehicle behind me paying attention?
• Will a door of one of these parked cars open?
• Will a squirrel or deer run onto the road?
Evaluating Risk in the Driving Environment
56
Execute in Time
• You identified a possible conflict developing between you and the blue car
• This conflict will happen because the blue car traveling 60 mph is going faster than the motorcycle which is traveling at 50 mph
• The blue car may cross into your path of travel to overtake the motorcycle
What would you do in this situation?
57
Virginia Space Management System
Execute In Time! • As the lane change occurred you had two options:
• slow down and allow the blue car to proceed into zone 1
• or change your position and move into the open zone 2
58
Execute in Time
Without proper searching, evaluating (decision making skills), you may execute the wrong decision
59

• Three-point turn• U-turn
• Midblock• At an intersection
If you miss an address or building and you do not have the option of driving around the block…
72
TurnaboutsMinimize risk by:• being sure local laws permit a turnabout — look for any signs prohibiting
the turn
• making sure you have at least 500 feet of visibility in each direction
• being sure you have enough space and time to complete the turn safely
• never making a turnabout near or on hills and curves
• checking continually for other traffic and pedestrians — check all zones around your vehicle

Parking Strategies
• Look for a parking space with enough room for entering and exiting easily
• Observe and follow all signs, laws, pavement markings
• Look for vehicles exiting parking spaces
• Avoid spaces at the end of parking lanes where being hit is more likely
• Avoid spaces near a large vehicle that block your vision when existing and other people’s ability to see you
• Avoid spaces with a poorly parked vehicle on either side
80
No Parking!
• Beside another parked vehicle (double parking)
• On crosswalks or sidewalks
• In front of driveways
• Next to painted yellow curbs or no parking signs
• In a parking space reserved for disabled persons
• On the hard surface of a road when no curb is present
Parking is NOT allowed
81
No Parking!
• Within 20 feet of an intersection
• Within 15 feet of the entrance to a fire, ambulance or Rescue squad station
• Within 500 feet of where fire trucks or equipment are stopped answering an alarm
• Within 50 feet of a railroad crossing
• Within 15 feet of a fire hydrant
82
Angle Parking
1. Signal intention, position vehicle three to four feet away from the space
2. Move forward until side view mirror appears to align with the first pavement line
3. Visually target the middle of the space and move slowly turning the wheel sharply
4. Once front enters space, gradually begin unwinding the steering wheel while monitoring the vehicles parked on either side
Parking diagonally to the curb
83
Exiting Angle Parking Space
1. Place foot on brake, signal intention, shift to reverse, search path of travel
• Back until your vehicle’s front seat is even with the back of the space, and begin turning the steering wheel in the direction you want the rear to go
• Constantly monitor the front bumper on the opposite side of the direction you are turning
2. Back into the closest lane; shift to drive and move forward
84
Don’t Develop These Bad Habits
• Failure to check traffic to the rear • Forgetting to signal• Parking too close to the line• Speed too fast• Steering insufficient or moving wheel too slowly• Failure to target to center of the parking space• Not using forward reference point and hitting curb• Forgetting to straighten wheels at the end• Parking too close to other vehicles• Forgetting to set the parking brake
85
Perpendicular Parking - Entering
1. Signal intention and position the vehicle five to six feet away from the space
2. Move forward until the side mirror appears to align with the first line of the space
3. Turn the wheel rapidly in the direction of the space controlling speed
4. Steer towards a target in center of the space and straighten the wheels
5. Position the front bumper three to six inches from the curb or end of the space ta
rget
86
Perpendicular Parking - Exiting
• Place foot on brake, signal direction of turn, shift to reverse, search area to the rear/sides
• Back until your side mirror is even with the bumper of the vehicle located to the side, begin turning the steering wheel in the direction you want to go
• Monitor the rear and your front bumper on the opposite side of the direction you are turning
• When the front bumper clears the back of the vehicle, stop, and shift to Drive
87
Parallel Parking on a Two-Way Street
STEP 1
• Select a space that is at least five feet longer than your vehicle
Flash your brake lights , put on your turn signal as you approach the space, and monitor rear traffic
• Place your vehicle approximately three feet from the vehicle you want to park behind, aligning your rear bumper with the other vehicle's bumper
• Put the vehicle into reverse and turn the wheels all the way to the right
88
Parallel Parking on a Two-Way Street
STEP 2
• Slowly back up until you are at a 45-degree angle using your side view mirror, back until you can see the headlight closest to the curb of the vehicle behind to establish the 45-degree angle
