Slow down! Reduce your speed before approaching a curve. Watch out for road signs warning of approaching curves so that you have ample time to slow down before steering through the curve. It is advisable to
drive below the posted speed limit
as you approach and drive through curves.
Where should you adjust your speed to steer through a curve?
Judge how sharp the curve is. Slow down before you enter the curve. Braking on a curve may cause you to skid. Reduce speed before entering the curve, and slowly lighten the pressure on the brake until
reaching the apex point
(where the car is closest to the inside of the curve line).
When driving through a curve what is normal speed?
When driving through a curve at normal speed,
accelerate gently after the midpoint of the curve
. reestablish a 3-second following distance on the vehicle ahead. avoid a collision with another vehicle.
When driving around a curve should you focus?
When driving around a curve, you should focus:
through the curve well ahead of your vehicle, along your path of travel
.
When rounding a curve a car tends to do what?
When rounding a curve, a car tends to:
Speed up
.
Why is it important to slow down when driving around a curve?
Any speed or steering adjustments required while in the curve should be very gradual to avoid losing control of your vehicle. The most important part of driving a curve or corner is to
slow down before you get to it
.
How do you negotiate a curve when driving?
- Keep slightly to the right of the lane center on right curves and in the middle of your lane on left curves.
- The sharper the curve, the more you need to reduce your speed.
- Look for traffic coming from the opposite direction.
What are the 3 parts to a curve?
A typical AS curve has three parts:
a flat, horizontal portion at low levels of output
, a middle section with a more-or-less gentle upward slope, and a steep or vertical portion at high levels of output.
What are 4 no passing situations?
Passing is illegal and unsafe in the following conditions:
Your line-of-sight is restricted or limited by a curve, hill, or weather conditions, e.g., fog, rain, snow.
When space is narrowed, and your front zones are closed
. Cross-traffic is present, even if there are no warning signs.
When driving down a mountain you should never?
Don’t go down a mountain road
any faster than you can go up it
. Don’t use your brakes to hold your downhill speed. Down shift to S or L – the only time you should step on your brake pedal is to slow while you are shifting down to a lower gear. Resist the temptation of zooming down a hill.
What is the outside force that is needed to overcome inertia when going around a curve?
The force responsible for the change in direction is called
centripetal force
. Centripetal force is necessary for an object to move with circular motion. The force that pulls out from the center on a body in circular motion is called centrifugal force and it increases with acceleration.
What is the minimum following interval?
A defensive driver maintains a safe following distance of
at least three seconds behind the vehicle
ahead and increases it depending on weather and road conditions.
When you double the speed of your car your braking distance?
When you double the speed of your car, your braking
distance quadruples
. As shown below, every time you double your speed, you multiply your braking distance by four. This piece of information will be important for determining your total stopping distance.
What are two things that will work on your vehicle as you drive around a curve?
Energy of motion and traction
will work on your vehicle as you drive around a curve. The energy of motion in your vehicle will try to make it go straight in a curve. The higher your vehicle’s speed, the more it will tend to go straight. Tire traction is the second force working for you in a curve.
What two forces work on a car as it goes around a bend or a curve?
When an object moves along a curved path, it is acted on by
centrifugal and centripetal forces
. This will affect your vehicle whenever you drive through a curved stretch of road. These two forces act simultaneously and pull in different directions. Centripetal force pulls an object towards the center of a curve.
How and when would you look into a curve?
Explain how your central vision should be directed into the curve. As the
car gets closer to the curve
, and it is time to select a new target, look through the curve with central vision until you see another straight-away for a new target.
