Semi-trailer or trailer with an improved stearing control which mainly consists of a chassis (4) and at least two stearable wheel shafts (5,6), whereby each stearable wheel shaft (5,6) is fixed to a support (10) which is provided in a rotating manner around a vertical shaft (11) on the chassis (4) and which is provided with a control to turn the stearable wheel shaft (5,6) concerned around the vertical shaft (11) concerned, as well as means which make it possible to couple the semi-trailer (3) or trailer (29) to a hauling vehicle (2), characterised in that each rotatable support (10) of the stearable wheel shafts (5,6) comprises a rod (18) which can be axially shifted in a guide (19) of the rotatable support (10) concerned, whereby both these rods (18), each with one far end (20) respectively, are connected to a common control in the shape of a turntable (12) which is fixed to the chassis (4) and which can rotate around a vertical shaft (X-X'), whereby said turntable (12) is provided with a drive (22) which moves the turntable (12) synchronously with the relative angular displacements (A) of the semi-trailer (3) or trailer (29) in relation to the hauling vehicle (2).
