Introduction to Backing
Turnabout Options
Backing Increases Risk
• Line-of-Vision Blind Area Larger to Rear
• Requires More Space to Maneuver - Back Tires Don’t Turn
• Must Yield to All Pedestrians and Vehicles
When Given the Choice, Move Forward
When You Must Back
• Look for LOS POT Blockages
• Know the Space You Intend to Occupy is Clear
Backing Straight
• Right Foot Firmly on Brake
• Shift to “R” – Reverse• 360 Degree Search• Pedestrians &
Vehicles
Backing Straight
• Hold Wheel at the 12 O’clock Position• Twist Body to Look Over Right Shoulder• Target – As you do when moving forward• Decrease Brake Pressure – Move at a walking pace• When Close to Obstacles Move at an Inch-by-Inch
Speed
Backing Turns
• Turn Head – Look to target area before turning wheel
• Turn wheel from the top down in the direction you want the back of the car to move
• Use two hands on the wheel• Check front swing to be
certain that the front of the vehicle doesn’t strike any object
Reference Point Usage
What is the reference point used for backing to a line in the rear?
What is the reference point used for backing to a line in the rear?
Yes! About a foot behind the door post or the middle of the rear side window
Discover the Pivot Point for Backing Turns
That point directly above the center of the rear tire
Rear Corner Post or Blind spot.
Standard Reference Point
It is at this point that one may begin turning the wheel.
Rear Corner Post or Blind spot.
The curb line appears to line up with the Rear Corner Post or Blind spot.
Pivot Point
When the nearest edge of the your intended lane lines up with the pivot point you may begin to turn the wheel
Turnabout Options
Changing Your Direction
Consider Your Choices
Turnabout Options• Go Around The Block
• Parking Lot - Pull in/out Forward
• Right Alley/Intersection Turnabout
• Left Alley Turnabout
• U-Turn
• Y-Turn - 3 Point Turn
Evaluate the Risks• Least amount of risk
• Some Risk – Many LOS-POT blockages in parking lots
• Reduced Risk - Backing in, pulling out forward
• High Risk - Backing into traffic
• High Risk - Crossing all traffic lanes
• Maximum Risk - Crossing traffic lanes & backing into traffic
1. Select location, check rear, tap brake lights, signal and check blind spot, leave traffic lane
2. Stop with-in 18 inches of curb, shift to reverse, 360 degree search and yield, target to rear
3. Back to pivot point, turn wheel from top down, check front swing
4. Back to safety stop, foot on brake then shift to drive
5. Signal left, when clear make a precision left turn

Illegal U-Turns
• At traffic-light controlled intersections when a sign prohibits it

Yield3. Target, Creep & turn wheel fast,
stop at front limit, shift to reverse, search 360 degrees
4. Target right rear, creep & turn wheel fast, back far enough to clear edge of roadway - one car length – 15 feet
