✔✔Stopping Distance is measured by combining: - ✔✔Driver Decision & Vehicle
Braking Distances.
✔✔Driver Decision Distance: - ✔✔Is the distance the vehicle travels between the
location where the driver identifies a hazard and first presses the brake pedal.
✔✔Vehicle Braking Distance: - ✔✔The distance traveled between the location where
the brake pedal is first pressed (by the driver) and where the vehicle comes to a
complete stop.
✔✔Steering: - ✔✔Is used to make minor adjustments in vehicle
direction or travel path.
✔✔Turning (Or Cornering): - ✔✔Is steering the vehicle around a central point or through
a turn.
✔✔Factors that impact TURNING include: - ✔✔- Vehicle Speed
- Vehicle Weight
- Road Conditions (e.g., dry; wet)
- Road Design (e.g., slope; curve)
- Vehicle Tires (e.g., tread; air pressure)
- Driver Attitude & Attention
✔✔To complete an efficient and safe turn, drivers must consider roadway position and
speed. - ✔✔True
✔✔The Turn Line: - ✔✔The path traveled through a turn (or location of patrol car).
, ✔✔The Apex: - ✔✔Is the lowest or closest point a motor vehicle reaches while inside a
turn.
✔✔Over-Steering: - ✔✔Occurs when vehicle rear tires lose traction and skid to the
outside of a turn (e.g., fishtail).
✔✔Over-steering causes include: - ✔✔- Improper Air Tire Pressure
- Braking Too Hard Into a Turn
- Abruptly Releasing Accelerator Going Into Turn
- Turning Too Sharp or Fast to Cause Unnecessary
Lateral Weight Shift
- Unnecessary or Improper Acceleration to
Overcome Rolling Friction on Rear-Wheel Drive
Vehicles
✔✔Under-Steering - ✔✔Occurs when the vehicle 'plows' straight without turning
because front wheels are sliding.
The vehicle continues in a straight line and resists turning from the direct course of
travel.
✔✔Under-Steering causes include: - ✔✔- Excessive Speed
- Slick Road Conditions
- Unnecessary or Excessive Braking While Turning
- Not Turning Sharp Enough For Curve Radius
✔✔Counter-Steering - ✔✔Is used correct a vehicle's travel path (or skid) by turning front
wheels in the opposite direction of skid.
✔✔Counter steering must be quick and smooth. - ✔✔True
✔✔Constant Radius Turns: - ✔✔Is where entry and exit sides share the same radius.
When making a constant radius turn.
Drivers should apex halfway through the corner and accelerate when exiting.
✔✔Decreasing Radius Turns: - ✔✔Is the most dangerous because entrance radius is
larger than exit radius (i.e., turn gets tighter or smaller later).
✔✔Decreasing radius are hazardous because they can deceive drivers into maintaining
speeds and positions more suitable for constant radius turns, whereby causing them to
oversteer. - ✔✔True
✔✔Increasing Radius Turns: - ✔✔Is where the entry radius is smaller than exit radius.
