Emergency Vehicle Operations (EVOC)
Human error is responsible for 90% of all vehicle crashes, which makes drivers the
most critical factor in motor vehicle operations. - ✔️✔️True
Factors that affect driver's ATTITUDE: - ✔️✔️- Overconfidence
- Lack of Confidence
- Self-Righteousness
- Aggressiveness
Laws of Physics: - ✔️✔️1) Kinetic energy
Energy an object possesses by being in motion.
2) Momentum
Is the combined mass and velocity of an object. An object in motion tends to remain in
motion until acted upon by an outside force.
3) Friction
Is resistance between two objects rubbing against each other.
* Rolling Friction
* Sliding Friction
4) Weight Shift (or Transfer)
Is a change in load placed on vehicle wheels/tires while in motion. More weight over the
tire means more tread is on the road surface. Less weight over the tire is more likely to
cause a slide or skid.
* Longitudinal
Occurs when vehicles are accelerating or braking.
* Lateral
Is side-to-side and occurs when vehicles turn.
5) Centrifugal Force
Centrifugal force pulls a moving object outward from the center of rotation.
6) Centripetal Force
Pulls a moving object inward toward the center of rotation.
Inspections conducted by officers are made when the patrol car is stationary and in
motion. - ✔️✔️True
, Three (3) main factors that directly impact basic motor vehicle operations are: - ✔️✔️-
Vehicle
-Driver
-Roadway
Vehicle Inspection Process - ✔️✔️1) Maintenance
2) Exterior
3) Engine Compartment
4) Tires
5) Breaks
6) Interior
7) Trunk
8) Performance and Response (In Motion)
Common driver distractions include: - ✔️✔️- Texting
- Being Lost
- RADAR Tone
- Eating or Drinking
- Talking to Passengers
- Typing on MDT or In-Car Computer
- Talking on Cell Phone or Police Radio
- Reading a Map or GPS Navigation System
Signs of driver sleep deprivation include: - ✔️✔️- Irritability
- Hallucinations
- Inability to Focus
- Impaired Judgement
- Increased Reaction Times
Steering wheel hand position is determined by driving
task. - ✔️✔️True
What are the different steering wheel hand positions? - ✔️✔️- 3 & 9 O'Clock
- Shuffle
- Hand-Over-Hand
- One-Hand
3 & 9 O'Clock (Steering Wheel Hand Position) - ✔️✔️Hand position is effective for
most high and low speed driving tasks.
Shuffle (Steering Wheel Hand Position) - ✔️✔️Hands remain close to 3 & 9 positions
with the wheel being shuffled between grip.
