Laws of Nature
Name 3 natural forces that affect vehicle control.
Possible answers:
Describe weight transfer for each: Pitch, Roll, and Yaw
Pitch: Front-to-rear or rear-to-front weight transfer
Roll: Side-to-side weight transfer
Yaw: Rear load shifting right or left
What are reference points used for?
To determine the vehicles position in relation to the road and other vehicles
What are the only two situations where you would utilize one-handed steering?
+100 if you can describe the backing position
Backing up in a straight line & Backing up with a trailer
-Left hand at 12 o'clock, looking over right shoulder
Name 5 places where parking is NOT allowed.
Possible answers:
What has a greater chance of rolling, a vehicle with a higher center of gravity or lower?
Higher
What causes pitch in a vehicle?
Acceleration or Braking
What are the two limitations that help to determine how far to pull forward and back up when driving?
Front and rear
What hand position should you use when driving?
+100 if you can give a benefit to this hand position
8 & 4
It prevents arm injury if the airbag deploys
It prevents oversteering
More of a natural position, less fatigue.
When backing up and turning, what should you monitor?
The front of the vehicle's "swing"
What natural force keeps an object in motion until acted upon by an outside force?
Inertia
What is the primary cause of Yaw?
+100 pts if you can give another name for yaw
Traction loss in the rear tires
Fishtailing
What lane position will you drive in the most?
+100 If you can say where that position is located within the lane
Lane position 1
The center of the lane
What steering technique should you primarily use?
Push/pull/slide
What turn about uses a driveway?
2-point turn
True or False: Understanding the Laws of Nature helps drivers make better decisions about vehicle input.
True
What is the primary cause of roll?
Sudden steering input
Describe why would be driving in either lane position:
Lane position 2 & Lane position 3
Lane Position 2: Left turns, Parking on the left side of the street
Lane Position 3: Right turns, Parking on the right side of the street, pulling onto the side of the road.
What is the purpose of antilock brakes (ABS)?
+100 If you can say what you do if ABS is engaged in emergency braking
To prevent wheels from locking up during braking
-Keep foot firm on the brake pedal.
What is the purpose of using reference points when backing up and turning?
To determine when you should start turning the steering wheel
What is the primary effect of gravity on a vehicle traveling uphill?
Increases the vehicle's weight
What primarily affects surface traction?
Weather conditions
What 2 factors affect how large a vehicles footprint is?
+100 what is the vehicles footprint?
Vehicle size & driver height
The vehicles footprint is the area surrounding the vehicle where the driver cannot see what is on the pavement.
What is reaction distance?
The distance a vehicle travels between recognizing a problem and applying the brakes
Name the reference points for 3 of the following +50 points for anything more:
Stopping at a stop line (front limitation)
Backing straight back to a curb
Lane position 1
Lane position 2
Lane position 3
middle of right rear passenger window
right headlight
left headlight
