When driving a vehicle around curves, the driver sometimes notices that he loses control of the vehicle and this is due to several reasons that I will mention here.

Anterior lower confinement
Its effect is that the car continues to drive straight around corners even though the driver is turning the steering wheel
 To steer the car, but it does not change direction as easily as usual

Causes of lower confinement

• Due to low air pressure in the front tires
• Because of the front tires, if they are worn and wiped
• Because of the weight of the car from the front
• Because of braking if the car does not have an ABS system
• Due to water accumulations, tree leaves, and the like

Posterior upper confinement

Its effect is that the car turns more than the driver expects
 It continues to deviate horizontally and forcefully from behind as a result of the weight and force of the impulse

Causes of upper confinement

• Due to low air pressure in the rear tires
• Because of the rear tires, if they are worn and wiped
• Due to the weight of the car or loading the car with a heavy load in the back
• Due to strong braking or sudden severe braking
• Because of water accumulations or tree leaves and the like, which makes the orientation process difficult
• Because of the strong winds coming from the side
