Difference Between Understeer and Oversteer, Let's Understand Here!
The terms understeer vs oversteer relate to steering sensitivity of the car while driving, both occur when the vehicle is in an abnormal condition which endangers the passengers and the driver. So what is the difference? Here is the explanation!
Definition of Understeer
Understeer is a term for a condition where the car is difficult to turn, thus continuing to go straight even though the driver has turned the steering wheel.
The causes of this condition vary, ranging from the driver turning the steering wheel too quickly or forcefully, slippery road conditions due to mud or wetness, issues with the electrical system, to problems with the car's steering mechanism.
This condition is quite dangerous as it poses a risk of collision with other vehicles or even going off the road. Therefore, when understeer occurs, the driver must be quick to address this situation.
Symptoms of Understeer
Here are some common symptoms that occur when a car experiences understeer, including:
- The car slides out of the corner because the front wheels cannot generate enough force to keep the car on the correct path when turning.
- The steering wheel feels lighter because the front wheels cannot generate enough traction for the car to turn as it should.
- A noisy sound is heard from the front wheels, as the front tires do not provide enough traction, causing the tires to continuously work to find better grip and produce noise.

How to Handle Understeer
If you experience understeer, immediately do the following:
- Press the brake pedal gently, as braking with high pressure can cause the tires to lock. Thus, the vehicle can skid when suddenly pressing the brake pedal.
- Release the gas pedal, so that the car's speed can gradually decrease by itself.
- Try not to panic, as the driver must remain fully concentrated to help identify the problem and take further action.
- Turn the steering wheel back when in a neutral condition, so that the wheels can reconnect with the steering.
Definition of Oversteer
Meanwhile, oversteer is a condition where the rear tires slip. Thus, when the car is turned at high speed, the rear tires lose traction, resulting in the car shifting and drifting.
In some extreme cases of oversteer, the car can spin out of control, posing a significant danger to the driver and passengers. The causes vary, ranging from the driver braking too hard, suddenly lifting their foot off the pedal, to worn-out rear tires.
How to Handle Oversteer
Here are some actions that can be taken when the car is in an oversteer condition:
- Steer the wheel back straight or towards a safer direction to avoid the risk of an accident.
- Reduce pressure on the gas pedal, do this slowly so that tire traction can return to normal and grip the asphalt properly.
- Maintain full concentration while controlling the vehicle.
Differences Between Understeer and Oversteer
There are several differences between these two car problems, including the following.
Causes
A car in an understeer condition is caused by the volume of worn front tires, resulting in less than optimal grip on the asphalt.
Additionally, this condition can also occur due to the grip of the front wheel braking system experiencing system failure or wear. Generally, understeer often occurs in FWD or Front Wheel Drive cars.
Physical Condition
In addition to the differences in causes, these two problems also have differences in terms of their physical conditions. A car experiencing understeer will have difficulty turning even when controlled by the steering wheel, and the direction of the vehicle's wheels remains straight.
Meanwhile, the condition of oversteer is when the car is at high speed and difficult to turn, resulting in control difficulties and loss of balance. Thus, the difference between understeer vs oversteer. Hope it is useful!
