방문운전연수 For years, Google has bet that self-driving cars would revolutionize how people get around. They’d be safer, use less fossil fuel, and lower transportation costs.
But billions have been invested in the technology, and it’s not yet ready to replace human drivers. Until then, we need to practice safe driving techniques.
Steering
One of the most important aspects of driving a 방문운전연수 car is knowing how to use the steering wheel correctly. It’s no wonder that learners spend multiple lessons trying to perfect this elementary skill. However, once mastered, steering can be a breeze.
The first thing to understand about steering is the hand-over-hand technique. It’s best for times when you need to turn at low speed or have limited visibility, such as when parking, according to NHTSA. To steer in this way, put your left hand between the 8 and 9 o’clock part of the wheel and your right hand between 3 and 4 o’clock. This will enable you to move the wheel in whichever direction you need.
A more advanced method is the pull-push steering technique, favored by some drivers. This involves pulling down on the steering wheel with your hand opposite to the direction you’re turning while pushing up with the other hand alternating as needed.
Another important aspect of steering is acquiring an accurate idea of your car’s dimensions. Many motorists imagine their cars to be three feet wider than they are and therefore give too wide a berth when navigating narrow streets or parking spaces. This can waste valuable fractions of seconds as you continually re-adjust your grip. To avoid this, learn to steer accurately and test your understanding of your vehicle’s dimensions by aiming at markers in an empty car park.
Acceleration
Acceleration is the rate at which your car increases its speed, or the change in its velocity. A car accelerates 방문운전연수 when the accelerator pedal is pressed, causing the throttle to open and allowing air into the engine, producing a spark that causes the piston to go down and rotate the crank shaft. This action is what produces the acceleration your vehicle feels, and can cause it to veer off course, which is why you must always exercise a delicate touch when using the gas pedal.
A driving skill that all drivers should hone is their ability to judge, almost as second nature, whether they can safely carry out a manoeuvre. This is called acceleration sense.
Having good acceleration sense allows you to accelerate up to the correct speed for a junction or hazard without having to use the brake pedal. This is also more fuel-efficient and can help prolong the life of your tyres.
When negotiating a turn or curve, smoothly accelerating through the corner will allow your vehicle to maintain weight balance, which can improve its grip on the road. It is best to keep the foot off the gas completely or to apply minimal pressure when accelerating, as abruptly slamming on it can cause your wheels to spin and lose traction. This can lead to a dangerous skid that could easily result in a collision.
Braking
The car’s braking system transforms the vehicle’s motion energy into heat through friction between the brake pads and rotors. This is why it’s important to press the brake pedal slowly and firmly until between 5 and 10 mph is reached.
If the driver presses the brake pedal too hard and quickly, he/she will jolt the car forward in its seat. This will not give enough braking power and the vehicle could go off course. In the old days without ABS, this might have led to a skid. This would make it very difficult to steer the vehicle in a different direction, and could even result in a collision with another vehicle or (heaven forbid) a pedestrian.
Braking is an important part of circuit driving as it allows the driver to control the car’s speed at the optimum moment for cornering. This requires observation, anticipation and planning – the car’s trajectory around the circuit and what will happen at each point on the track.
For slow corners, the sooner you can get on the brakes, the better. This will allow the tires to reduce their grip more and reduce the risk of locking up. It is also recommended to brake into a bend with one fluid movement, avoiding slamming the brake pedal. This can transfer the weight of the car too quickly and unbalance it, especially with a higher centre of gravity cars such as SUVs.
Turning
Turning corners seem to be the most difficult driving maneuvers for new drivers to master. The reason for this is that turning requires you to consider a number of options and then make a decision about what you will do. Many new drivers tend to stare at the pavement or the car in front of them while they are trying to decide whether it is safe to turn. This causes the vehicle to drift to either side when they do finally start to turn and is one of the reasons why new drivers often cut the corner or turn wide.
To prevent this from happening you must practice your steering technique in a controlled environment such as a parking lot before you attempt to drive on the road. This will help you to learn how much to move the wheel to keep it moving in a straight line. Generally, you will need to slightly move the wheel every few seconds to keep it on the road and at a constant speed.
When you are about to turn, slow down and use your signal to warn drivers behind you. You should signal about 100 feet before turns in residential and city driving areas, and 200 feet in highway and rural areas. Then, gently begin turning the wheel and slowly accelerate to return to your original speed.
