Deformable curb barrier

A kerb barrier comprising:

• a first barrier member having a length, the first barrier member defining a cavity;
• and
• a second barrier member in the cavity of the first barrier member that extends substantially along the length of the first barrier member, wherein a base of the second barrier member is fixable to a base of the first barrier member,
• wherein, upon side impact, a region of the first barrier member is configured to bend relative to the second barrier member about a first bending point defined by the first barrier member,
• wherein the first barrier member is configured to act on the second barrier member such that the region of the first barrier member and a region of the second barrier member are configured to bend about a second bending point defined by the second barrier member,
• wherein the second bending point is spaced apart from the first bending point wherein, in an undeformed state, a clearance gap is provided between a wall of the first barrier member and a wall of the second barrier member.
