What is under and oversteer and how are they fixed?
Understeer:

-
Back off what you are doing too much of
What is the purpose of EVoC
Find the limits of police vehicles
Back off to an 85% level so you drive within a safety margin
Find your personal limitations
EVoc braking techniques - what are they? Is one better?

They are: _________
Identify
Contribute
Speed
Curves
Passing/following vehicles
Hills
When faced with a potential collision, drivers need to rely upon their _____ and _______ _______ abilities to drive out of the problem area.
They also use those to make ______, ______ ________.
Skills
Decision making
Quick, correct decisions
Four steps to decision making
OODA
Observe
Orient
Decide
Act
Which parts of OODA are in perception time? Reaction time?
Perception: observe, orient, decide
React: act
What is the average perception time?
Average reaction time?
1/2 to 3/4 second for both
Total response time (perception + reaction) for average driver is 1-1.5 seconds. True or false?
True
What are some additional distractions for law enforcement when driving?
Radio
CAD
Telephone
Prisoner
Passenger
Searching for addresses
Criminal activity
Traffic violations
What is the racing line vehicle path?
High-low-high
A racing line is a ballistic trajectory where the exit point is determined by the entry.
Control issues with this line
What is the reconnaissance line vehicle path?
High-high-low
Creates a straight line exit which is the priority for this technique
What are the 4 zones of a corner?
- Approach (90-95% braking)
- Steer and trail off brakes
- Neutral throttle
- Dial out steering leading to max throttle
Everyday recruits must?
- Complete full vehicle check and inspection check
- Remove trash or other items found
- Clean windows+ any paint markings inside
- Report any vehicles with less than 1/4 tank
- Make note of signs of damage or mechanical issues
How many seconds for eye lead
12
_______ attitude is the controlling factor in applying skill
Driving
What do you do at end of day
- Park vehicles as instructed
- Ensure all vehicles secure
- Remove trash
- Equipment returned; vehicle keys hung on keyboard
- Report any issues
- Fuel vehicles if under 1/2 tank
Tires contact patch: size of what when in constant speed or stationary?
Size when in motion?
Fist
Thumb
What are the three braking techniques?
Normal: 4-6, smooth application
Threshold: 8-9, straight line, stopping just before ABS
Trail: lift off braking as you introduce steering
What is a time + distance problem that you won’t have a choice as to what/when happens?
Driving emergency
What is the measure for crashes? What you need to consider?
Metres/second
Need to consider: direction of travel, other people, bystanders
Tire pressure should be within ______ PSI of the manufacturer recommendation
1-2
Vehicles with tires displaying the three types of damage should not be used. These are:
- Stonewall bruise
- Deep sidewall cuts to the metal
- Wear bars on tread of tire
What’s the term for a reduction in stopping power that can occur when brakes are used in a repeated manner, especially when driving in an emergency or R1 manner?
Brake fade
What is the CPS Policy definition of an emergency
À présent or imminent event that has a high probability of death or GBH, or substantial or significant property damage that requires a prompt police response
What is the difference between UHRRR 63(1) and 64(1)
63(1) drive with lights/sirens
64(1) no siren
Both give permission to drive faster than speed limit etc but 64(1) you better be able to articulate why you don’t have your siren activated (surveillance, danger in alerting offenders etc)
List the four parties in the duty of care hierarchy
Victim
Public
Police
Offender
When is it appropriate to respond to a call with a R1 response
Need to consider:
- The likely potential risks to your victim if you do not attend quickly
- Who else is potentially affected by the decision to go R1
- Who is affected by my decision driving R1
True or False: a priority one call always gets a R1 response
False
When driving R1 you come to a complete stop at negative right of way intersections, intersections with limited or no visibility for cross traffic, and any intersection where hazards are present and all lanes cannot be accounted for.
True or false
True
The goal of EVOC is to create safe, responsible, professional drivers with an emphasis on safe and guaranteed arrival. True or False
True
What are the three control inputs?
Steering - direction
Throttle - speed
Brakes - stop/slow
Are airbags designed to replace seatbelts?
Nope. Designed to work with them, not replace them.
How can you stay safe when driving with airbags?
- keep airbag deployment area free from equipment and other debris
- deployment depends on speed, weight sensors, impact point
- shuffle steering keeps arms safe from airbag
What Is the TPMS? Does it substitute for proper tire maintenance and inspection?
Tire pressure monitoring system
No.
Why do you want to pay attention to the condition of your brakes?
Because they are the only thing that will safety stop you.
Should you use caution when stacking stuff near or on the electronic control box?
Yes! Remember the soup incident with Cst Killbride.
If you take care of your equipment, what will your equipment do?
Take care of you
When driving non-emergency with no lights sirens you don’t need to follow the road laws?
False
Yes you must follow all road laws
If the siren isn’t activated do we have right of way?
Nope
Are we immune to the consequences of our actions? Civil law suits?
Nope, not immune. Open to civil suits and it isn’t just how we drive but also how we park and where.
