Reversing the algebraic sign on the velocity vector reverses the direction of motion. Is the same statement true for the acceleration vector?

Yes.
To understand why, let's imagine a particle in motion in a straight line, which is represented by a velocity vector. Force on it can make it curve right or left, which is represented by a infinitesimal acceleration vector of opposite algebraic signs, one for each direction. This is one example.

acceleration is also a vector quantity.
A simple explainaiton is:
Acceleration is changing velocities over time
Velocity has direction, therefore, acceleration also has directions

It turns the acceleration into breaking, with respect to the direction you've defined as "going faster"
