Approach to Intersection
Topic 3 Lesson 2 Approach to Intersection Step 1 (Search) Identify Intersection Identify Controls Check Rear Areas Search for Intersection Risks Step 2 (Evaluate) Scan Open Side Areas First Scan Closed Side Areas Look for Closed or Changing Frontal Areas Step 3 (Execute) Adjust Speed Maintain Lane Position or Stop Behind Crosswalk Proceed Through Open Space Area or Stop Behind the Crosswalk T – 3.28

Approach to Intersection
Topic 3 Lesson 2 Step 1 (Search) Identify the intersection. - Determine the type of intersection and number of intersecting roadways. - Determine your lane position (right turn/left turn/straight) prior to the intersection. Identify any controls--signal lights, stop or yield signs and information signs. This will provide you with the information you need to adjust speed or position. Check rear areas. Check if rear zones are open or closed. If the rear zone is closed, tap your brakes a few times before stopping— the brake lights will flash and communicate to the driver to the rear that you are slowing or stopping. T – 3.28a
10
Approach to Intersection
Topic 3 Lesson 2 Step 1 (Search) continued Search for possible intersection problems. Look for problem areas, such as construction or road maintenance, pedestrians on or near the intersection, or obstructions to your line of sight that may include buildings, parked vehicles, trees, fences, etc. Adjust speed. Intersections are unpredictable and you may have to stop. Be prepared. The closer you get to an intersection, the more important it is to adjust vehicle speed. Adjust lane position. Choosing the proper position (LP 1, 2, or 3) will lower the risk of possible conflicts by providing you the maximum amount of space between your vehicle and other vehicles. T – 3.28b
11
Approach to Intersection
Topic 3 Lesson 2 Step 2 (Evaluate) Scan open side areas first. Try to position your vehicle in an open zone with a clear line-of-sight to your path-of-travel. Be prepared to stop for a closed zone or line-of-sight restriction in your path-of-travel. Scan closed or changing areas. Identifying closed zones early will allow you to prepare. The greatest chance for conflict is in areas where vehicles may cross directly into your intended path-of-travel. Look for closed or changing frontal areas. A closed front zone occurs when there is a yellow or red traffic light, yield or stop sign, or anything moving into your intended path of travel. T – 3.28c
12
Approach to Intersection
Topic 3 Lesson 2 Approach to Intersection Step 3 (Execute) Adjust speed. If you have identified a closed zone, prepare to reduce speed or stop. Maintain lane position. Your lane position (LP 1, 2, or 3) will indicate your intentions to other drivers and provide you with the greatest distance between opposing vehicles and/or other objects. Stop behind stop line, crosswalk, or before entry to intersections, when needed — proceed through open space area when traffic controls permit and your path-of travel is clear. Note: Most crashes occur in intersections! T – 3.28 d

Developing Good Driving Habits
Topic 4 Lesson 2 Developing Good Driving Habits Preparing Driver and Vehicle Smooth, Gradual Starts and Stops Using Reference Points for Vehicle Placement Getting Visual Targets before Movement - Using a Vision Control, Motion Control, Targeting, and Steering Control Sequence Visually Targeting the End of the Path of Travel as far as 15, 20, or 30 seconds from the Vehicle C+ A+ Based on concepts from Mottola, F. R. (1999). Empower Yourself. p. 5 T – 3.33

Developing Good Driving Habits
Topic 4 Lesson 2 Developing Good Driving Habits Be Alert to Changes to the Line of Sight (LOS) or the Path of Travel (POT) Adjust Speed and Lane Position to Increase Space to Front, Side, or Rear for Restricted LOS-POT When Approaching a Red Light, Adjust Speed to Time Your Arrival for a Green Light C+ A+ Based on concepts from Mottola, F. R. (1999). Empower Yourself. p. 5 T – 3.34

Developing Good Driving Habits
Topic 4 Lesson 2 Developing Good Driving Habits Prior to Intersection Entry, Check the Left, Front, and Right Zones or Areas - Check the area that can be viewed best first so that more time can be focused on the obstructed area Whenever Your Foot Goes to Brake or Accelerator, Check the Rear View Mirror Prior to Moving to the Left or Right, Check Side View Mirror and Mirror Blind Zone C+ A+ Based on concepts from Mottola, F. R. (1999). Empower Yourself. p. 5 T – 3.35
20
Developing Good Driving Habits
Topic 4 Lesson 2 Developing Good Driving Habits Make it a goal to maintain a four-second following interval from the vehicle in front and to the rear. - This protects you from the unexpected actions of other drivers to the front and rear. When stopped behind vehicle, leave space to move around the vehicle in case of an emergency. Reduce stress by being courteous rather than competitive while driving. Competitive drivers are not winners. C+ A+ Based on concepts from Mottola, F. R. (1999). Empower Yourself. p. 5 T – 3.36

Vehicle Operating Space
Topic 2 Lesson 1 There are seven basic areas of operating space for a vehicle. Six of the space areas (zones) are around your vehicle, and the seventh, or central space, is the space your vehicle occupies. T – 4.12 a

Vehicle Operating Zones
Topic 2 Lesson 2 Vehicle Operating Zones Vehicle Operating Space To assist you in learning zones and their purposes we have colored and numbered each for easy identification. Right-Front Zone (Maroon) Right-Rear Zone (White) 5 3 Central Space Area Front Zone (Yellow) Rear Zone (Blue) 1 6 Left-Rear Zone (Red) Left-Front Zone (Green) 2 4 Direction of Travel A zone refers to one of the six spaces around your vehicle. It is the width of a traffic lane and extends as far as you can see. A zone has three characteristics, it can be OPEN, CLOSED or CHANGING. T – 4.13
