A vector quantity has both magnitude and direction. In order to show a change in direction, or to represent direction full stop, it must be through positive and negative values, otherwise it would be almost impossible. A negative velocity isn’t some sort of abstract anti-velocity sort of concept. It just means going backwards instead of forwards, or going left instead of right, you get the picture
