You are changing from the left lane to the middle lane. Did you have the right of way over the vehicle entering the lane from the right in this situation?

Why?

When two vehicles move into the same lane from either side, the driver entering from the left must give way to the driver entering from the right. You therefore had to give way to the silver car on your right when moving from the left lane into the middle lane.
