I would say no. Since vector location is subjective, only the direction and magnitude is fixed, two opposite vectors could be overlapping, fully or partial or not at all. To say they are parallel would imply that cannot overlap.
So while it is possible for opposite vectors to be parallel, it is not an assumption that can be made.

It is a vector with the same magnitude (size) but acting in the opposite direction.
The result will also be a velocity vector. Draw the first vector. From its tip draw the negative of the second vector ( ie a vector with the same magnitude but opposite direction). The the resultant would be the vector with the same starting point as the first vector and the same endpoint as the second. If the two vectors are equal but opposite, you end up with the null velocity vector.
You do vector addition.

equal and opposite
Vector addition derives a new vector from two or more vectors, and vector resolution is breaking a vector down into its two or more components.
the opposite to vector addition is vector subtraction.
opposite direction.
The zero-vector has no direction.
It is a vector with the same magnitude (size) but acting in the opposite direction.
Equilibrant vector is the opposite of resultant vector, they act in opposite directions to balance each other.
The result will also be a velocity vector. Draw the first vector. From its tip draw the negative of the second vector ( ie a vector with the same magnitude but opposite direction). The the resultant would be the vector with the same starting point as the first vector and the same endpoint as the second. If the two vectors are equal but opposite, you end up with the null velocity vector.

Two Scalars that go in opposite directionsOne scalar and one vector!
It is a vector that has the opposite direction to the reference positive direction. (A vector is one point in space relative to another.) Negative vector is the opposite direction
