True.
For a coasting roller coaster (neglecting friction and air resistance), mechanical energy is conserved: as potential energy is lowest at the bottom, kinetic energy is highest there (the car's speed is greatest). If external forces (brakes, motors, large friction) act, that can change the situation.
