An energy-absorbing structure (10) comprising a sacrificial member (12) and a skin (14) for covering one side (16) of the sacrifical member (12). The skin (14) has an array (18) of grooves (20) formed in the surface (22) closest to the sacrifical member (12). The grooves (20) provide lines of wakness which improve yieldability of the structure (10) when in collision with large objects (e.g pedestrians), but without adversely affecting damage resistance to small object, e.g. stone chippings.
