You, the driver of the grey car, have decided to change lanes to the right. Your actions:

1. 1You will start to change lanes, because you are to the left of the driver of the white car on a one-way road and therefore have the right of way.
2. 2You will start to change lanes, because you have the right of way with respect to the driver of the white car.
3. 3You will give way to the driver of the white car and, having made sure that it will be safe and will not create obstacles or a hazard for other road users, perform the manoeuvre.
