Cars, like any other machines, are exposed to malfunctions that affect their work, and one of these malfunctions is the car's deviation on the road while driving, either to the right or left, and this should not happen because the car must remain traveling in one direction even when the hand is lifted from the steering wheel.

As you know, the deviation of the car on the road on any side is very dangerous and may cause a major accident - God forbid - and put you and those around you at risk, so if you notice that your car is deviating on the road, you must take it to the dealership or an authorized mechanic to perform the necessary maintenance and eliminate the issue that caused the deviation.

Causes of swerving while driving

The reasons for the car's deviation on the road while driving are many, and they are:

Low tires pressure

The most common cause of car swerving on the road is low tire pressure, as the low amount of air in one of the tires on the right side, especially the front tire, will cause the car to swerve to the right side and vice versa, and here you must refill your car's tires with the correct air pressure mentioned on the information panel on the driver's door inner column or by reviewing the owner's manual or searching online.

Tires tread wear

One of the reasons for the car swerving on the road is also the wear and tear of tire treads due to their age or due to incorrect aggressive driving, and if the tread of one of the tires is significantly worn, it will cause the car to swerve on the side where the worn tire is located, and be sure to always check your tires, because significant wear may lead to a tire blowout and cause an accident - God forbid -.

Damaged tires

Car tires are made to withstand the rigors of harsh driving on the roads in various conditions, but tires are exposed to some damage due to hitting a rock or a road edge or due to their age, which makes them inflated on one side or damaged in a way that affects their rotation, and if any tire is damaged in your car, you will notice the car swerving on the road, especially at speed, with the feeling of concussions as well.

Damaged rims

Collision with potholes, bumps, roadblocks and others can lead to damage and denting of the rim of the rim, and the damaged rim can cause the car's stability on the road and will lead to its deviation, and the greater the damage and the higher the speed, the greater the deviation for sure, and you will notice with the deviation, vibrations in the steering wheel at high speeds due to the damage to the rims.

Tires not rotating correctly

Tire alignment ensures that all tires rotate correctly and with equal centrifugal force on all sides, If the alignment device notices that a tire is rotating incorrectly, it gives a reading by placing the alignment on it with a specific weight to compensate for the incorrect rotation and for the car to drive steadily and quietly, however, if the alignment is incorrect or if your car tires lack alignment at all, your car will swerve on the road.

Misalignment tires

Tire balance ensures that the angles of the front and rear tires are correct and free from any deviation, even if it is small, because the deviation of the tires from their correct position will cause the car to swerve on the road and face difficulty in steering if the deviation is strong, and will contribute to faster tire wear in the area where the balance is incorrect.

Incorrect tire rotation

Incorrect tire rotation in the front and rear can lead to uneven tire wear, which can cause the car to swerve to one side, so make sure to rotate your tires at the company's recommended intervals, which is usually at 8,000 km, or you can rotate your tires with every oil change.

Brakes wear

If you notice that your car swerves right or left when you press the brake pedal at high speeds, it means that there is uneven wear on the brakes on one of the sides to which the car has swerved, and you may also notice during the swerve hearing a grinding or whistling sound coming from the worn brakes, and this sound indicates the need to replace them as soon as possible so that the brake response is intact and the car does not swerve on the road again.

Steering system issues

The steering system is the system responsible for steering the car through the driver's input on the steering wheel, and if one of the parts of this system is damaged or malfunctioning, especially the parts connected to the tires directly, your car will swerve on the road, especially at high speeds.

Suspension issues

This system is responsible for ensuring the comfort of you and those with you in the car from road damage such as potholes, bumps, stones and others, and it is a system that contains many internal components connected to the tires, and if one of these components is worn or broken, it will affect the movement of the car without a doubt, and thus may increase the likelihood of swerving on one side while driving.
