It is shown that in alkali-halide crystals at low temperatures the deceleration of dislocations, whose high concentration may be caused by the internal photoeffect under illumination of the crystal by visible light, is influenced by their interaction with polarons. The deceleration force acting on a moving dislocation that interacts with polarons at not only strong but also weak coupling is calculated.
