Not all drivers are responsible for observing the speed limit. To attract their attention, especially in residential areas, artificial road bumps, which are popularly called "speed bumps". And although today they are quite common, even drivers with a certain experience do not always move these bumps correctly.
During braking of a moving vehicle the main forces arise at the point of contact of the wheels with the roadway. After pressing the brake pedal, the car does not stop immediately. Enough to remember school lessons physics, where it was about inertia - the force that continues to pull the car forward. Its center of influence is much higher than the road surface. It turns out that at the same time two forces pull the car in different sides directed to different parts of it. At this point, the front of the car receives the greatest load, and its rear end rises. Significantly increases the pressure on the bearings and springs of the front suspension.
Hitting a speed bump while braking will inevitably cause a blow to the front suspension. Of course, if sometimes you do not have time to notice artificial bumps, there is no big disaster. However, if you do this regularly, the car will not last long. That is why the correct passage through the "speed bump" involves early braking, and when the obstacle remains one or two meters, the brake pedal is released. Thus, the springs will take on the entire load, and the suspension will not suffer at all. Even if you did not have time to notice the unevenness, release the brake pedal - a blow will follow, but only on one side.
Sequencing
I. Passage of a low speed bump.
1. Seeing the sign, we slow down, pressing only the brake.
2. A few meters before the speed bump, we also press the clutch - the car moves into the coast.
3. When the machine rear wheels is on top of the speed bump, downshift to 2 or 3 and press the gas pedal.
II. Difficult cases when the distance between the bottom of the car and the road is minimal, as well as when the obstacle is too high.
1. Reduce the speed to almost zero.
2. We pass to 2 or 1 gear.
3. We drive into the unevenness obliquely so as not to tear off exhaust pipe or bend the car body.
III. If the moment is lost, then evaluate the situation, as applying the brakes may cause the machine to lean forward and cause a more powerful impact than if you did not brake.
After flying over an obstacle, evaluate the consequences and take pictures with your camera of the signs, speed bumps, and damage received by the car.
Any specific recommendations for speed limit No. It is better to stick to a uniform low speed so that the car parts do not rumble during the speed bump. Experienced drivers recommend overcoming the IDN at an angle - with such a maneuver, even low car will not catch on the artificial unevenness of the bottom.
In city traffic, it is not always possible to maneuver and choose the angle of crossing, so the main thing is to drive at a moderate speed and release the brake pedal when the wheels are in direct contact with the obstacle.
When approaching a speed bump, remember that the car in front of you can choose any of the ways to overcome the obstacle, and therefore slow down in advance and keep your distance.
Today is not difficult, however actual video lesson, it sounds - how to pass speed bumps. I tried my best to simply tell, and shoot this question on video. For professional drivers this lesson will not be interesting (you can not waste time), but for beginners it will help to protect the suspension from damage and further costly repairs ...
First, let's figure out what it is?
speed bump - this is an artificial bump in the road that forces the driver to slow down to a safe 30 km / h. Usually installed on busy roads before pedestrian crossings. Now, by law, it must be made of rubber and be flat and narrow. However, there are older types (installed before), which are made of asphalt, usually large, massive.
So why should you slow down in front of him?
It's simple, if you drive over this obstacle at high speed, you can damage the suspension (rubber parts are especially affected - silent blocks, bushings, stabilizer struts, thrust bearings, you can knock down), wheels or rubber (the disk can be dented, a bump can come out on the rubber), especially if it is made of asphalt.
Now the process itself - let's point by point.
The passage of this irregularity can be divided into two different ways.
1) This is the way of travel - coasting . The bottom line is that, before unevenness, we include neutral gear, we slow down the speed to 20-30 km / h and the car coasts itself through it without any tangible harm to the suspension.
driver's side view
When the car has already approached the bumps, you do not need to apply the brakes (you do not have such a high speed), on the contrary, you need to release the brake pedal for a smooth passage of the car. The thing is, when we brake, the center of gravity is transferred to the front of the car, and if there is also a speed bump in front, then the suspension will receive maximum shock, which affects almost all elements badly.
2) The second way of travel is when we practically stop . Before the obstacle itself, we stop the car, turn on the first gear, and slowly drive through the roughness. This method is especially suitable for beginners who cannot yet coast the car.
We stop
from the driver
As you can see, both methods are not difficult, they can easily be mastered in a few days of moving around the city. True, for the first type, you need to master coasting (there will be a separate lesson about it).
As usual, the text and photos may not be entirely clear, so I post the video version of the lesson, more detailed information. In this video, both options, and there is a view, both from the salon and a view from the street with clear comments.
That's all, I think this one is not complex video a lesson that will help you save the suspension of your iron "horse", because its repair now is oh, how not cheap, especially if you have an expensive foreign car.
Very often on the road you can meet an obstacle that reduces or limits the speed of your car. They are called "speed bumps". They are not uncommon in our country. This obstacle forces the driver to slow down, reduce speed on a dangerous section of the road or on unregulated intersection. They can also be found where there is an increased risk of creating accidents.
As a rule, such speed limiters are made of metal structures, rubber-plastic or slides rounded from asphalt. It's worth saying that The most effective colors for speed bumps are yellow and black. It's shown numerous studies. It's hard not to notice such a "speed bump" even in dark time days. Therefore, artificial obstacles are extremely useful, especially in a large city.
Drivers overcome these obstacles on their way every day, and sometimes several times a day. But not everyone knows if they are doing it right. After all, even experienced drivers can move the “speed bump” incorrectly, as a result of which you can easily ruin the suspension of the car.
1. For whom they came up with speed bumps
Perhaps, many are interested in the question, for whom and for what they came up with artificial bumps, or, in a simple way, “speed bumps”. They were created, first of all, for those drivers who do not pay attention to the road at all, to road signs, to pedestrians, to pedestrian crossings and who do not take into account the speed of their movement. Recently, there have been a lot of speed bumps, especially in settlements.
Warnings about some kind of danger on the road do not always stop the driver, who is in a hurry somewhere and almost does not pay attention to road signs. Therefore, they create artificial irregularities. It is clear that if road signs cannot stop the driver from traffic violations, then the "speed bumps" exactly help to reduce speed in a dangerous area. And since drivers do not really want to damage their car, they slow down.
How to move a "speed bump" is taught in driving schools. Both in theory and in practice. But some not so conscientious instructors don't explain it to the drivers and therefore they don't know how to do it. And this can damage your car.
2. Pay attention to them
Without a doubt, you need to pay attention to speed bumps. First of all, in order not to spoil your own car. After all, spoil and, and brakes, and bearings, and bridges, and much more. Everyone should understand that you need to watch not only for artificial obstacles, but also for the road as a whole. Of course, there are such dexterous drivers who believe that on high speed they just rush through the obstacle and nothing bad will happen. But it's not. Need the right approach. Because then you have to rake up not very pleasant consequences.
3. Options for overcoming obstacles
Often, all sections of roads with speed bumps are equipped with special information signs that warn drivers about artificial unevenness. The main actions at the entrance to the "speed bump": slow down, reduce speed to 5 km / h, release the clutch, generally take your foot off and the brakes, give free rein to the car, let it move over the artificial unevenness by itself, in this case, the load on the suspension will be minimal, and then feel free to press the gas. Drivers often do this. There are several options for overcoming obstacles.
3.1 Coasting
This way of overcoming obstacles is one of the most popular. The driver must reduce the speed to 20 km / h in advance, release the brakes, and the “speed bump” moves in neutral gear. And then turns on the transfer and again makes the movement of the car. It is not recommended to slow down on a speed bump and right in front of it. The entire weight of the car is then transferred to the front of the car, and a huge load is placed on the suspension. And in winter, everything can end up very scary if the driver brakes sharply somewhere a meter away from the obstacle. And even good studded tires will not save. After all, the road there is very slippery.
3.2 At an angle
Another option is to move at an angle. When approaching a speed bump, the car must be placed at an angle to it. But at the same time, it is important to follow the road very carefully, look around so that there are no cars. One will roll first front wheel, and then something else. This move is correct.
3.3 Driving with braking
This way of overcoming an obstacle is carried out by reducing the speed and engaging the neutral gear. Then there is no particular harm to the suspension. The speed must not exceed thirty kilometers per hour. And the brake pedal, in turn, must be released altogether and not put pressure on it.
You can also turn on the first gear directly in front of the speed bump. This method is very common among beginners. You need to drive up to an obstacle, then stop, and only then slowly press the gas and roll. This method eliminates the possibility of damage to the thresholds on the car. It also won't damage the bottom of your car. If this happens, then the damage done will be minimal.
3.4 One-way driving
Very often you can see how drivers drive through an artificial bump under the curb itself, clinging to it. This requires more attention. Because you need to watch out for cars that are moving in parallel with you, and also make sure not to damage the wheels on the curb. Experts say that the suspension will wear out faster this way.
Especially if you do it very often. There is an opinion among motorists that if high speeds overcome pits and speed bumps, then the suspension will not have time to work out its own, and there will be no harm to it. But this is not true, because, overcoming obstacles at a very high speed, the suspension experiences a frontal impact, and not just a blow from below. It is clear that the damage is significant. And the consequences of such actions will be too serious and will hit your pocket hard.
4. Don't Forget Pedestrians
The main object of attention for any driver should be pedestrians. Under no circumstances should they be forgotten. Pedestrians and speed bumps are inextricably linked. After all, artificial bumps on the roads are precisely designed to ensure that drivers slow down their cars when they approach the most likely place for the sudden appearance of pedestrians. It is no coincidence that they are installed, as a rule, near playgrounds, schools, stadiums, pedestrian crossings, parking lots, parking lots and other crowded places. Be careful on the road. Take care of your life and the lives of the people around you!

They call an artificial obstacle that was created on the road on purpose. It forces a motorist to slow down at an unregulated intersection, at pedestrian crossings, or on a dangerous stretch of road. But even for experienced motorists, overcoming such an obstacle is a real problem.
dangerous obstacle
As we were told car instructors, if it is wrong to pass a speed bump, then this threatens rapid wear many units and components of the car, in particular, bridges, brake system, bearings and other elements.
Most often, drivers slow down a little before passing obstacles. It is after this that under the weight of the vehicle, the front suspension is subjected to extreme pressure.
The problem is that there is not always enough time to slow down to a minimum, so when you hit an obstacle, the suspension gets hit. Moreover, after passing an obstacle, many drivers do not pay attention to rear axle, which are "knocked" directly on the "speed bump".
How to safely overcome the speed bump?
As a rule, all sections of roads with speed bumps are equipped with special information signs that warn drivers of artificial unevenness. So it follows a few meters before the "policeman" to slow down, release the brake pedal, and then smoothly move over the obstacle.
Some motorists move over such bumps at an angle. In this case, the suspension does not experience much pressure, because there is only one slight push on each wheel.
This option makes it possible to secure the car, but this is not entirely correct. Passing an obstacle in this way is possible only on roads where there is no heavy traffic. Overcoming the "speed bump" slowly, drivers often face another problem. These are impatient car drivers who begin to honk and rush everyone around. Here the advice is simple: do not pay attention to them, because the durability of the car is more important.
Some drivers find that bumps in the roads will not be as noticeable if they are driven at high speed. This is fundamentally not true. Overcoming the "speed bump" requires a specific approach:
- you see the corresponding road sign;
- two meters before the artificial unevenness, slow down;
- sharply press the brake, after which we release the car, thus pecking forward;
- after returning to the starting position, when the speed is too low, and the car lacks traction, we press the gas. This gives the car a push forward and unloads the front axle;
- it is recommended to add gas to the "speed bump";
- we do not recommend flying such irregularities at high speed.
Remember that your thoughts when driving a speed bump should not be only about him. If you see an obstacle, you don't need to concentrate on it.
Remember that you are on the road, in a car stream, and here the driver's attention comes first.

Sometimes a sign - a warning of a possible danger ahead along the road - is not a stop signal for a hurrying driver. To avoid accidents due to such drivers, special obstacles have been installed on the tracks that will force the motorist to slow down in front of dangerous area or pedestrian crossing. No man wants to damage his car because of such a barrier. And if you do not notice it, then in any case you will have to slow down.
It is the speed bump that makes you slow down. How it is safest for yourself and the car to drive on it is taught in driving schools. First, they tell the theory, after which they consolidate knowledge with practice. Sometimes instructors forget to talk about speed bumps, as a result, students have no idea how to cross this barrier. As a result, both the driver and the car suffer. To avoid such cases, we will analyze in detail the technique of driving through artificial interference.
What is a speed bump
A similar barrier is needed on the highway so that the driver slows down in unsafe areas of the road. Such deceleration is required in front of a zebra crossing or in crowded places (for example, a city center). Under current rules traffic, speed bumps should be made up of rubber. That's just on Russian roads you will meet them very rarely: all obstacles of this type are made of asphalt. The disadvantage of such a “cop” is that if you drive through it incorrectly, you can severely damage the car.
How Not to Overcome an Obstacle
When you press the brake, the corresponding pads of the machine are automatically blocked, and the pressure between the wheels and the road increases significantly. There is an inertial force acting in the direction of movement, and there is a braking force, it is directed against the car. It turns out that these two forces act in completely opposite directions. And there is a moment during which the front of the car is pressed against the track, and the back, on the contrary, rises. Also in this case, the pressure on the front suspension is greatly increased: it depends on the force of deceleration.
If, during the above process, the vehicle passes through an obstruction, the front suspension is subjected to enormous loads. Having passed incorrectly through a speed bump several times, you can say goodbye to her. And if you do this periodically, it is easy to disable the entire machine.
How to move over an obstacle
There are two main ways to drive through an artificial barrier, which allow you not to endanger either the driver or the car. The first method is to slow down in advance. Thus, you do not load the suspension, and the car runs over the “cop” coasting. To do this, you just need to reduce the speed of movement and engage the neutral gear. remember, that allowable speed in this case - 30 km / h. And don't forget to release the brake pedal before passing through the obstruction.
The second option is to almost completely stop the car in front of the speed bump. Engage first gear and move quietly. This overcoming obstacle is a great solution for those new to the road who have not yet mastered the technique of rolling.
By the way, some drivers pass through such an obstacle at an angle. This is because there is not a lot of pressure on the suspension, because each wheel experiences only a small push.
In custody
In order not to damage the car when overcoming a speed bump, you need to clearly know how to do this. The article describes the two most common and main ways that allow you to keep the suspension of the car intact. Do not rely on luck, it is better to competently travel than to spend a substantial amount on the repair and repair of vehicles in a car dealership.
