MPTC Emergency Vehicle Operations UPDATED ACTUAL Questions and
CORRECT Answers
*vehicle
3 main factors that impact basic motor vehicle *driver
*roadway
rolling friction friction that occurs when an object rolls over a surface
occurs when two solid surfaces slide over each other;
sliding friction
faster than rolling friction
Weight transfer occurs when vehicles accelerate or brak-
Longitudinal weight shift
ing
Weight transfer to the side and occurs when the vehicle
Lateral weight transfer
turns
*check the exterior/interior
*check engine fluids
*tire tread depth (2/32)
*braking system
Inspections *have all defects fixed as soon as possible
*cease driving if there is a decrease in car perfor-
mance/mechanical failure
*do not use if there is any equipment warning light indi-
cator
*Responsible for 90% of all motor vehicle crashes
Human Driver Error
*most critical factor in motor vehicle operations
*overconfident
*lack of confidence
Driver attitude
*self-righteousness
*aggressive
Help prevent crashes and keep drivers safe during crash-
Traflc Occupant Protection Systems (TOPS) es
*seatbelts
, *airbags
*ESC
Integrated with the ABS, traction control, steering and yaw
Electronic Stability Control (ESC)
control systems
*used to reduce speed or stop a moving vehicle as quickly
as possible with minor steering adjustments
Threshold braking
*applied and maintained without engaging the ABS, lock-
ing-up wheels, or skidding
Trail braking Braking and turning at the same time
*driver identifies the reason that requires them to stop
3 events of stopping distance *driver must take action to stop by braking
*vehicle must come to a complete stop
Vehicle rear tires lose traction and skid to the outside of a
Over-steering
turn
Vehicle "plows" straight without turning because front
Under-steering
wheels are sliding
Used correct a vehicle's travel path (or skid) by turning
Counter-steering
front wheels in the opposite direction of skid
*most dangerous because entrance radius is larger than
Decreasing radius turn exit radius
*driver must apex late
*entry radius is smaller than exit
Increasing radius turn
*driver must apex early
*driver must recognize how the previous turn impacts the
subsequent turn
S-turn *can create extreme lateral weight transfer
*common mistake is for the driver to apex too early in the
final turn
Roadway influences 2/5
