What happens if you turn the ignition to 'lock' while driving?

Turning the ignition to 'lock' while driving causes the steering wheel to lock, making it impossible to turn it. This is a crucial safety feature designed to prevent the vehicle from being driven when the ignition is turned off or locked, which can happen when someone inadvertently tries to remove the key. If the steering locks while the vehicle is in motion, it can lead to a loss of control, significantly increasing the risk of an accident. Therefore, it is essential to ensure that the ignition is in the appropriate position while driving to maintain control of the vehicle.
