Chapter 6 - See- Think- Do Flashcards
See- Think- Do
See - scan for hazards
Think - which hazards are more dangerous
Do - reaction appropriately
See - Observation
-look at least 12 seconds ahead
-scan side to side
-glance in mirrors
Every 5-8 seconds
What are the percentages of motocyle crashes
65 - involving motorcyles are multi -vehicle
80 - are other driver is at fault
35 - not other vehicles are involved.
Observing behind
Mirrors
Blind Spots
Should Checks
Observing behind - Mirrors
-every few seconds
-before slowing or stopping
-before planning to change road position
Observing behind - Blind spots
-keep track of vehicle seen in the mirror
-if disapears you know they are in blind spot
Observing behind - Shoulder Checks
- whenever changing direction or road position
-make sure blind spot on side is clear.
Use mirror and should check when ever planning to:
-pull out from side of road
-pul over to side of road
-change lanes
-change lane positions
-turn
What percentage of crashes happen at intersections in BC?
60 percent
Observing at Intersections
-Approaching
-Stopping and Starting
-Turning
Observing - Approaching
- look, left, centre, right and left again
-check crosswalks
Observing - Stopping and Starting
-slow down to stop check mirrors for behind
-clear view of intersection
-edge forward carefully if interseciton is blocked
Observing - Turning
-shoulder check
-scan intersection
-eye looking in the direction you want to go.
Hazard Perception
Space Conflicts
Suprises
Vision Blocks
Space Conflicts
-2 road used try to move into same space
-keep space margins
-oncoming vehicles, left infront of you
-pedestrians crossing road
-cyclist moving up beside you when planning to turn right.
Suprises
-unpredictable Hazard
-driver on/off brakes then suddenly slam on
- driver weaving back/forth -Impaired?
-poorly loaded Pickup
-open road and sudden gust of wind
Vision Blocks
-Parked Van
-never pass on crest of hill
-trees, fences near intersection
-large truck in next lane
-fog, rain & darkness
Poor Road Surfaces
Lose Traction:
-loose grave
-wet leaves/debris
-railway tracks
-wet/icy roads
-slippery road markings
-storm drains
-metal surfaces
Think - What is the 2 thinking process?
Assess Risk
Choose Best Solution
Assess Risk
-Slow down and be cautious
-move to center lane
Your on a windy road, going up hill and a car behind is keeping distance. At the crest of the hill you see a large truck in the opposite lane and a car in your lane coming at you. The shoulder is not a good surface to ride on. What do you do?
Slow down
Steer out of the way
Honk horn and flash brake lights.
Choose a solution
Speed Control
Steering
Space Margins
Communication
Speed Control
-is there room to avoid hazard?
-can I slow down on the road conditions?
Steering
Can I stay in control if I steer away from the hazard?
Space margins
- enough space to slow down when slippery
-enough space for vehicle behind to slow down
-enough space to move onto the shoulder
Communication
Honk
tap brakes
-never rely on road users to see you
Do - Once you have assessed Risk and chosen a solution what is the Do steps?

What is the pecentage of multi vehicle T-bone or side impact motorcycle crashes?
31% - usually occurs other vehicles turns infront of an oncoming motorcycle
Speed Control
Appropriate Speed
Steady Speed
Maintaining appropriate Speed
-safest is slowest
50 km/h in cities /towns
80 km\h outside of cities/towns
Maintaining a steady speed
use, gears, brakes and throttle
-high gears to increase speed
-low gears to decrease speed/ more power
- front brakes powerful -70% of stopping power.
-apply brakes gradually increase pressure
Is it legal to coast down hill in neutral?
No, you need to be in gear to safely control your vehicle.
Physics for riders
Interia - keeps you going, faster more force
Traction -grip tires on road - road condition highly impact this.
Gravity - riding down hill, more distance to stop
Steering
Low-speed
Countersteetring
Handling Curves
Steering a low speed
Low = Upto 10km/h
-handlebars to left to turn left
-handlebars to right to turn right
-balance - body upright
Countersteering
Higher than 10km/h - steadier
-lean to make a turn
-lean to the curve
-push right, lean right, go right
-push left, lean left, go left
Handling Curves
-Slow down before entering a curve
-Faster you go the harder you push the handlebar to turn into the curve
-brake abruptly = loose traction
-hit wet or rouch patch = loose traction
-lean to much = skid and fall.
Space Margins
Space In front
Stopping distance
Space Behind
Space Beside
Lane position
Choosing a safe gap
Space In Front
- 2 seconds of space in front to stop
- 3 behind a large vehicle
- 4 seconds in bad weather
- measure by picking a object
- count 3secs when the vehicle infront passes the object
Stopping Distance
- momment you notice a hazard and when you stop
-3/4 of a sec to see-think
3/4 of sec to do
-braking distance depends on your speed
double speed = 4 x the braking distance.
triple = 9x the braking distance
Space Behind
- turning off a highway look in mirror - tailgaters!
-slow down guadually
What are the strategies for dealing with tailgaters?
- move to another lane
-turn right at the next intersection
-pull off the road so they can pass
-double flashing brake lights - maintain dominant lane position ( left )
-change lane position and change back.
Space Beside
-1 meter on each side
- leave an escape route to avoid hazard
Land Position
Always choose Maximum visibility
Space:
Visibility
Traction
Space Behind
- turning off a highway look in mirror - tailgaters!
-slow down guaduall
Space - Lane Postion
dominant lane position (left)
away from large vehicles
distance from medians parked cars and debris
Visibility - Lane Position
lets you see well ahead
Traction _ Lane Position
position with good traction
clear of debris
stay away from painted /plastic lines
What are the strategies of choosing a safe lane position?
-Crest of hill - move to center lane position
-Curves - best view through the curve ahead
-Trucks/Large Vehicles = Right position and 3secs before moving back
-Weather - Heavy gusts - Center Lane
What are dangerous lane positions?
Lane Splitting - vehicle could change lanes or open a door, no space margin and illegal
Riding on the shoulder: dangerous/traction and illegal
Ridding side by side: reduces space margin
Choosing a safe gap.
Stopped and proceed
- 2sec per lane to go straight
-5secs to turn right and get to 50km/h
-7secs turn left and get to 50km/h
What determines if a Gap is enought space to enter?
- Speed of traffic
- time to complete your manoeuvre
-time to accelerate
Communication
Visibility
Eye Contact
Turn Signals
Brake Light
Horn
Vehicle clues
Visible Communication
make yourself visible.
headlight on during day
bright cloths
Eye Contact Communication
eye contact with vehicle that may pull into your path.
eye contact with pedestrians/ cyclysts
Turn Signal Communication
- not automatic switches
-Be timely - signal way ahead of time
-Be clear - not too soon
-Be visible - always use then or hand signals too
-Mean what you say = always cancel after manoeuvre
-Only use your left arm for hand signals
Brake Light Communication
tells behind youi that your slowing down
-flashing before you slowdown
– slow down suddenly
– slow down unexpected place
Horn Communication
Quickly get someones attention:
- approaching intersection same time, unable to make eye contact
-passing someone that doesn’ see you and they are entering your lane
- parked car looks ready to pull out
- car backing out into your path
-pedestian about to step out in your path and you can’t stop in time.
Vehicle Cues Communication
- ## lane position can tell other what your doing to do.
