Velocity is a vector quantity
Vector quantities have both magnitude (size) and direction.
The assignment of positive and negative values to velocity is left to the aboserver
For example, if the velocity in the right to left direction is assigned a positive value, then the velocity from left to right will have a negative direction.
In other words, velocities in opposite directions will have opposite signs.
A vehicle moving in the Northward direction can be given as 33m/s, then another vehicle with the same magnitude of velocity but moving in the Southward direction will be given as -33m/s
