Apparatus (101) for controlling movement of a vehicle (100), a system (201) and vehicle 5 (100) comprising the apparatus (101), and a method (500, 600) for controlling the movement of a vehicle (100) are disclosed. The apparatus (101) comprises a controller (10) configured to receive first signals from a receiving means (202) in dependence on received transmitted signals from a remote control device (200) indicating a requested motion of a vehicle and to receive second signals indicative of a value of traction of the vehicle. A maximum speed 10 value for the vehicle is determined in dependence on the value of traction of the vehicle and/or on one or both of the detected pitch and roll angles of the vehicle (100). The controller (10) provides an output signal for controlling speed of the vehicle (100) based on the requested motion. The output signal is limited dependent upon the maximum speed value determined by the controller (10).
