Answered Questions A+ Graded
2 seconds - -dry surface and braking out of problems at speeds less than 35
mph.
-3 seconds - -dry surface and braking out of problems at speeds to 45 mph.
-4 seconds - -dry surface and braking out of problems at legal speeds to 65
mph.
-5 seconds - -When roadways are slippery, When visibility is poor due to
weather conditions, When driving at night, When driving at higher speeds
(50 mph or more), When following large vehicles, When you anticipate
dealing with an in-car distraction
-6 areas visible to the driver - -rear left, front left, rear, front, rear right,
front right
-Perception distance - -how far your vehicle travels, in ideal conditions
-Reaction distance - -how far your vehicle continues to travel
-Braking distance - -how far your vehicle will travel, in ideal conditions;
while you are braking
-Total stopping distance - -the total minimum distance your vehicle has
traveled
-s in SEE - -SEARCH for objects or conditions
-e 1 in SEE - -EVALUATE the projected path ahead for alternate paths of
travel
-e 2 in SEE - -EXECUTE appropriate adjustment(s)
-Inertia - -the law of motion. A property at rest wants to remain at rest.
-Body in motion - -keeps moving until something stops it.
-G - -a standard unit of acceleration or deceleration.
-Extending the time of impact - -is the basis for keeping people safe in a
crash.
, -Car size and weight - -When two vehicles of the same size and weight
collide the occupants would experience the same deceleration, this would be
the same as a single vehicle crashing into a rigid barrier.
-Energy - -the ability to do work (the stuff that makes things move)
-Kinetic energy - -the energy an object possesses due to its motion, the
rapid transfer of kinetic energy is the cause of crash injuries.
-Crashworthiness - -the protection a car offers its occupants during a crash.
-Good crashworthiness - -the safety cage or body of the car remains intact
after a crash, all the damage confined to the front end and occupant
compartment slows down at a gentler rate.
-Poor crashworthiness - -the safety cage or body of the car is collapsed and
driven backwards, the damage is not just confined to the front end of the
vehicle.
-Controlled deformation - -he frame or body of the car is designed to "give"
or "collapse" on impact in a controlled manner to maintain the integrity or
structure of the passenger compartment.
-Traction - -The adhesion, friction or grip between the tires and the road
surface.
-conditions that can affect traction - -Surface materials, Substances on the
road, Surface conditions, Banked roadway, Crowned roadway, and shoulders.
-Factors influencing the effects of inertia - -sharpness of a turn or curve,
speed, size, height, weight, roadway slope or crown, roadway surface
condition.
-Driving uphill - -A driver must accelerate to keep a constant speed and
overcome the force of gravity.
-Driving downhill - -The force of gravity tends to boost speed, increasing the
stopping distance.
-To maximize traction... - -Avoid sudden input when accelerating, braking or
steering, Focus on executing one input at a time - brake, then steer, then
accelerate.
-Characteristics of risk - -Always present, perceived, is sharedm can be
changed, can be analyzed, can be altered.
