A pole arrangement comprising: - a hollow yielding pole having a tubular external wall of sheet metal; - a foundation for anchoring the pole to the ground, this foundation having a vertical cavity for receiving a lower section of the tubular external wall with the tubular external wall extending through an opening at an upper end of the cavity; and - a ring-shaped wedge element extending around the tubular external wall, this wedge element being arranged at the upper end of the cavity and clamped between the tubular external wall and an inner wall of the cavity in order to secure the pole in the cavity by wedging, characterized in: - that the wedge element on its inner side is provided with supporting projections, through which the wedge element bears against the tubular external wall, wherein these supporting projections are arranged at a distance from each other as seen in the circumferential direction of the wedge element and wherein there are intermediate free spaces between the supporting projections as seen in the circumferential direction of the wedge element in order to allow parts of the tubular external wall to be pressed into some of these free spaces when the tubular external wall is subjected to buckling in connection with a collision against the pole; - that a reinforcement element is mounted to a part of the section of the tubular external wall received in the cavity in order to counteract buckling of this part; and - that an upper end of the reinforcement element is arranged at a distance from said opening of the cavity as seen in the axial direction in order to allow, in connection with a collision against the pole, buckling of the part of the tubular external wall located between the upper end of the reinforcement element and the opening of the cavity. - a hollow yielding pole having a tubular external wall of sheet metal; - a foundation for anchoring the pole to the ground, this foundation having a vertical cavity for receiving a lower section of the tubular external wall with the tubular external wall extending through an opening at an upper end of the cavity; and - a ring-shaped wedge element extending around the tubular external wall, this wedge element being arranged at the upper end of the cavity and clamped between the tubular external wall and an inner wall of the cavity in order to secure the pole in the cavity by wedging, - that the wedge element on its inner side is provided with supporting projections, through which the wedge element bears against the tubular external wall, wherein these supporting projections are arranged at a distance from each other as seen in the circumferential direction of the wedge element and wherein there are intermediate free spaces between the supporting projections as seen in the circumferential direction of the wedge element in order to allow parts of the tubular external wall to be pressed into some of these free spaces when the tubular external wall is subjected to buckling in connection with a collision against the pole; - that a reinforcement element is mounted to a part of the section of the tubular external wall received in the cavity in order to counteract buckling of this part; and - that an upper end of the reinforcement element is arranged at a distance from said opening of the cavity as seen in the axial direction in order to allow, in connection with a collision against the pole, buckling of the part of the tubular external wall located between the upper end of the reinforcement element and the opening of the cavity.
