Škoda 31Tr SOR is a low-floor articulated trolleybus produced in cooperation of Škoda Transportation (electrical equipment and assembly) and SOR, which supplies the body based on the bus SOR NB 18.

Rear axle is VOITH brand, as well as medium axle, the front axle is own production with independent wheel suspension. Only rear C axle is propulsed.
