Collision Avoidance Evasive Manoeuvers This lesson will focus on safe and responsible driving to avoid collisions by studying basic evasive manoeuvers. It will also focus on detection and recovery from skidding and sliding. WHAT IS AN EXAMPLE OF A EVASIVE MANOEUVER?
You are traveling at 80 KM/PH, if this truck turns right, what would you do? Brake! But if it still appears that you will crash into them, use the ____________.
Be prepared! Large vehicles will often pull out, causing you to slow down for them.
Will a car be attempting to pass it up? What should you be searching for when you see a large, on-coming truck?
If a vehicle began passing that truck coming right at you, what would you do? STOP and THINK If you have to swerve to the right to avoid a head-on How much should you turn the steering wheel? Don’t over react. Usually only slight turn of the steering is necessary Also, if possible keep the left tires on the pavement. Don’t over react. Usually only slight turn of the steering is necessary Also, if possible keep the left tires on the pavement. …again use the shoulder
Especially watch for passing on hills when your sight distance is reduced.
If someone began passing you right now, what would you do? Brake and move over as much as possible to the right.
W What should you do in this situation?
W
If you’re not paying attention and you drop your wheels onto the shoulder, what should you do and not do? Ease off accelerator, then gradually turn the wheels back onto pavement. Do not brake hard and do not jerk the wheel to the left.
Braking Techniques Controlled (Threshold Braking) - applying your brakes hard enough to slow the vehicle without locking up the brakes. If wheels do lock, ease off brake enough to allow wheels to roll again. Continue with technique until stopped. ABS Braking - uses a computer to prevent wheels from locking up. Press down hard on brake pedal. You will feel pulses or hear clicking. Continue holding pedal down until you stop. Steering is possible because wheels continue to move.
You are not paying attention as this curve approaches. Your back end begins skidding to the right. You have antilock brakes (ABS). What do you do? Hold the brake pedal down hard, while steering quickly to the right. Also, be ready to counter steer while keeping your eyes focused on where you want to go.

Adjusting Driver Behaviour For different driving conditions
What are some problems associated with sun glare? Everything is harder to see. STOP and THINK What effect would a dirty windshield have with sun glare? It would make everything much harder to see
What could she do to minimize the direct sun glare?
Drop the sun visor.
Also, be aware of sun glare upon drivers when you are a pedestrian. It’s likely this driver would have a hard time seeing you if you were to begin crossing the street.
As the sun begins to set, don’t forget to________________________.
In some open field areas, high winds could cause dust over the road causing a slippery situation. BEWARE OF DUST OVER ROAD
Use low beam lights Reduce speed Increase following distance If very bad get off road What are some things you should remember about driving in fog? In Motion magazine, a General Motors publication
Where is it more likely to be foggy? In low lying areas, costal regions and by lakes.
Sometimes it can be very thick…slow down!
What factor here can cause a loss of traction?
Especially around curves, reduce your speed.
Driving in hot/windy weather Avoid driving taller vehicles like recreational campers or trucks because they have a greater susceptibility to tipping in strong winds. What are some problems that can occur with very high winds? Even smaller vehicles can be pushed into an on-coming lane. Also, be aware of the wind created by large trucks as they pass by.
Driving in Rain
What about your following distance in rainy weather? Double or triple it. Also, in rainy weather you must use your __________.
What is a problem following large trucks in rainy weather? Their large tires throw it all on our windshield. Be sure you have a good supply of window washer.
Sometimes it can really be difficult to see! What is a problem following large trucks in rainy weather?
Roadways are most slippery when it: ___________________ Roads accumulate dirt and oil which mix with the first few minutes of a rain causing a pasty gooey substance that is very slippery. After some heavier rain, this “summer ice” is washed away. Be careful of sudden movements with the steering wheel, quick acceleration, or hard braking.
Driving in Rain
What is important to remember when going through shallow water? Hydroplaning is possible. Keep moving slowly.
What is important to remember when approaching deeper water? Keep moving slowly Dry your brakes when through the deep water How do you dry wet brakes? - one foot on gas…one foot applying pressure to brake
Strategies in the Snow
Perhaps the most important thing about driving in snow is to __________________________
Also be aware that snow storms may obscure traffic signs. What is this?
On this one way street what are you searching for? Cars or pedestrians obscured behind large snow piles.
You’re turning right at the intersection. What is a concern that you have? The slippery turning surface. Also, is another car coming? The slippery turning surface. Also, is another car coming?
What are three important things you must do to make this right turn safely? Slow down before the turn, more than you feel is necessary. Then, coast around the turn (stay off gas and brake). Do not accelerate until you straighten out.
You are on a wet road intending to turn right. What do you notice about the turning surface?
Should this car attempt to pull out quickly, it would probably ________its wheels.
With the slippery pavement, what are you anticipating as the light turns yellow? STOP and THINK We are also on a very slick surface. How should you accelerate when it’s clear? Very gradually, otherwise we will spin our wheels.
If you get stuck in deep snow, what should you try to do to get unstuck? “Rock” the car, shifting from drive to reverse.
Review time…how much do you remember?
