MPTC EVOC Exam Study Guide

Questions and Answers

1. How to inspect a vehicle: 1. Maintenance 2.Exterior (leaks, loose parts, lights, snow, dirt) 3.Engine compartment (fluids, wires, hoses) 4.Tires (cuts, bubbles, depth, pressure) 5.Brakes 6.Interior (driver controls, passenger area) 7.Trunk (wrench, spare tire, first aid, flares) 8.Performance and response (braking, steering, handling) 2. What to do if there is a decrease is in patrol car performance or handling: - Immediately cease driving
2. T.O.P.S: Traffic Occupant Protection Systems help prevent crashes and keep drivers safe during a crash
3. Who should wear a seatbelt?: All front and rear passengers, including prisoners

5. How quickly does an airbag inflate? How fast (MPH)?: Half a second up to 200 MPH 6. How fast does a vehicle need to hit something for the airbags to deploy?: - Vehicle needs to travel greater than 10 MPH for airbags to deploy
6. To accelerate and brake, what foot should you use: Right, never use your left foot driving
7. threshold braking: Used to reduce speed or stop a moving vehicle as quickly as possible, with minor steering adjustments
8. How to apply threshold braking: Apply/maintain max amount of pedal pressure WITHOUT ENGAGING ANTI-BRAKING SYSTEM (ABS), LOCKING UP WHEELS, OR SKIDDING
9. Trail braking: Braking and turning at the same time. Used before entering and making a turn
10. Stopping distance: Total number of feet a moving vehicle needs to COM- PLETELY STOP

12. Stopping distance - 3 events: 1) driver identifies hazard that causes him to stop

2. driver must take action to stop by braking
3. vehicle must come to a complete stop

13. How is stopping distance measured: Combining driver decision and vehicle braking distance
14. Driver decision distance: Time between when the driver identifies the hazards and first presses the brake
15. Vehicle braking distance: Distance traveled between location where brake pedal is first pressed by driver and vehicle comes to a complete stop

16. Apex of a turn: Lowest or closest point a motor vehicle reaches while inside a turn
17. During a turn, never apex until when: Never apex until you can see around or out of a turn
18. What percentage of all non-emergency law enforcement crashes happen while driving in reverse: 50%
19. Vehicle factors that contribute to MV crashes: Laws of physics and vehicle inspections
20. Kinetic energy: the energy an object possesses due to its motion (EX. A vehicle's weight and speed)
21. Momentum: The product of an object's mass and velocity
22. What is faster sliding or rolling friction ?: Sliding friction
23. Two types of weight shift?: Longitudinal and lateral
24. When does longitudinal weight transfer occur?: Vehicles are

accelerating or braking

25. When does lateral weight transfer occur?: When vehicle is moving side to side
26. Difference between centrifugal and centripetal force?: Centrifugal pulls a moving object outward centripetal pulls a moving object inward
27. What percentage of crashes is human error responsible for?: 90%
28. Competence bias: When people overestimate or do not recognize skill deficien- cies
29. self-righteouness: Drivers who believe they are above the law and never wrong
30. When are people most likely to crash? Civilians and police: Less than 5 hours of sleep 3 hours into an officer's shift
31. Do not use these methods when steering (2): Upper hand grip hook and turn

32. Common roadway hazards include:: Weather, road design and light condi- tions
33. Driving on standing water: Never drive through standing water before checking the depth band confirming the vehicle is capable of passing
34. Most effective way to avoid crashes?: Reduce speed
35. Space cushion: The clear or available space around a moving or stationary patrol car to maneuver and take evasive action
36. Seconds for space cushion: 2-3 seconds - normal driving conditions 3-4 seconds - normal night driving conditions 5-6 seconds - rain, snow, ice or gravel covered roads

37. Defensive driving: Process of minimizing risk and maximizing time needed to avoid a crash
38. What do officers need to do when at an intersection that is contrary to the right of way: Come to a complete stop 39. T/F patrol car warning devices ARE suitable for defensive driving and DO guaran- tee the safety for other drivers, officers and pedestrians: False 40. T/F DO NOT pass on the right side when emergency warning lights are being used: True
39. Emergency warning devices: Lights and sirens
