In order to allow the driver to control the speed and ensure the safety of pedestrians.Speed ​​bumps are now set up in many places，For example, the entrance of the community、School、Parking lots and some intersections without traffic lights, etc.。

Maybe some drivers will ignore its existence，But don’t underestimate it，If you drive improperly for a long time，Your car will suffer a lot of damage。

Many car owners think that the car passes through the speed bump at an angle，The body bounce is not that big，So the damage will be smaller。In fact, the car body passed diagonally，The body sways slightly from side to side，It is also easier to cause uneven stress on the left and right suspensions，Damage suspension system。For the entire spring、Shock absorbers and the entire body (frame)，will produce greater losses。

Unilaterally passing the speed bump is the choice of many car owners。Many car owners have such a habit，I just saw that the length of the speed bump did not cover the entire road，There is still room on the left and right，No speed bumps，You will use two wheels on one side to pass the speed bump。

They think this can reduce the damage on one side。In fact, they were right，That’s true。But one problem was ignored，The impact force is all borne by one side，It’s been a long time，Suspension is easy to dislocate、Deformation，Four-wheel alignment can also cause problems！Tires also wear out！If you have done this before，It is recommended to perform four-wheel alignment in time！So this approach is also incorrect。

Of course，There are also car owners who ignore the existence of speed bumps，Especially for cars with a relatively high chassis，For example, suv，Normally choose fast pass，Doing so will produce a great impact on the vehicle suspension，The downward rebound is large after suspension contraction，Using it this way for a long time will cause damage。If the speed bump is high、The speed is fast，Excessive impact on the car's suspension，The phenomenon of "knocking" the chassis may also occur。

It’s okay that the speed bump is intact，If the speed bump is damaged，Only the nails left to fix the speed bump，It may puncture the tires when passing quickly，A situation that causes a tire blowout。

When braking and decelerating, the center of gravity of the body will move forward，If you step on the brakes and pass the speed bump，That is to put all the weight of the body on the front wheels，It will seabet mycause the front shock absorber of the vehicle to be compressed again in the compressed state，Not only does it cause great damage to the shock absorber，Cannot alleviate the vibration。

Observe the road conditions ahead in advance，Especially when the vehicle has reached the speed limit section，Reduce speed，Linear braking after finding the speed bump，Slow down in advance，The speed will probably drop to 10~20Km/h。If you don’t reduce the speed，The greatest damage to tires and suspension，In severe cases, the wheel hub may also be damaged。

2. Two wheels pass the speed bump at the same time

Keep both wheels together over the speed bump，The left and right wheels contact the speed bump at the same time to balance the impact force on the tires on both sides，To balance the forces on the left and right suspension systems，Minimize damage，It may be a little more bumpy when sitting in the car。But the car may reduce the damage from relatively large damage to very small damage，It’s a better balance。

3. Reasonable use of brake and accelerator

Release the brakes before the wheels are ready to pass the speed bump，The center of the vehicle will move backward，Release the load on the front shock absorber，Let the front shock absorbers be in good condition to meet the impact of the speed bump。The front wheel passes the speed bump，That is, when the speed bump is located in the middle of the vehicle，Don’t rush to refuel and move forward。Wait for the rear wheels to pass the speed bump based on the forward inertia of the vehicle, then slowly apply fuel linearly and continue moving。(Pictures and text from the Internet，If copyright is involved, seabet loginplease contact us to delete)
