What action should be taken in the event of an unintended lane departure?

When a driver experiences an unintended lane departure, the most effective and safest action is to slowly steer back into the lane without jerking the wheel. This approach helps maintain control of the vehicle and reduces the risk of losing traction or swerving into another lane or off the road. Gradual steering ensures that the vehicle can smoothly transition back into its designated lane, which is crucial for both the driver's safety and the safety of other road users.

Accelerating or steering sharply might lead to overcorrecting, which can cause the vehicle to swerve uncontrollably, increasing the risk of an accident. Similarly, applying brakes immediately could lead to a loss of control, especially if the vehicle is traveling at a higher speed or if the road conditions are not ideal. Thus, the advised method of gently steering back into the lane helps to ensure a smooth recovery from the unintended departure.
