Study Notes
Vision Types in Driving
- Focal vision is primarily used for reading signs.
- Central vision is essential for depth perception.
- Peripheral vision helps detect motion from the sides and is sensitive to fatigue, drugs, and speed.
Field of Vision
- Field of vision refers to what is visible while looking ahead.
Visual Lead-Time and Following Interval
- Full visual lead-time for safe driving should be 20-30 seconds.
- At speeds of 50-55 mph, maintain a following interval of 3-4 seconds.
Visual Search Pattern
- Visual search includes:
- Visual lead area
- Line of sight
- Path of travel
Reference Points for Driving
- Reference points are crucial for judging vehicle position and help with areas not visible from the driver's seat.
Vehicle Balance and Weight Transfer
- Ideal vehicle balance occurs when the vehicle is stationary.
- Roll describes the weight transfer from side to side.
- Pitch refers to the weight transfer forward or backward.
Maintaining Vehicle Balance
- Consistent vehicle balance is maintained through:
- Precise steering
- Smooth acceleration
- Controlled braking
Braking Techniques
- Braking transfers the vehicle's weight forward.
- Threshold braking is the technique of stopping just short of wheel lockup.
Stopping Procedures
- Position the vehicle near the curb or edge of the roadway when stopping on the right side.
- Tapping the brakes before full pressure helps signal intentions to other drivers.
- It is unnecessary to signal when pulling to the curb to stop.
Backing and Turning Procedures
- Stopping 3-6 inches from a curb requires a reference point different from the right headlight.
- To back to the right, steer right, not left.
- Backing straight is safest with the left hand at the 12 o'clock position while looking over the right shoulder.
- U-turns are not the safest method for changing directions and may only be legal at intersections in some cities.
- Backing out of traffic is preferable to backing into traffic.
General Safety Rules
- If line of sight and path of travel misalign, decrease speed for safety.
