Speed can never be negative.
Velocity is a vector quantity. It has a magnitude and a direction associated with it. The magnitude is always positive. The direction can be positive or negative. As speed is the magnitude of velocity, it can't be negative.

no it is not possible for speed to be negative because speed cannot be zero or below as it is a vector quantity.
TPS:
speed is scalar and it can be 0.
