A vehicle impact attenuator that can be installed at low cost in a narrow installation space, immediately stop a colliding vehicle, and effectively mitigate the impact on the vehicle; the vehicle impact attenuator comprising: a shock absorber ( 10 A) that deforms upon a collision by a vehicle to reduce the impact on the vehicle; a support ( 20 A) for the shock absorber ( 10 A); and a holding portion ( 30 A) that holds the support ( 20 A) in a vertical position in the installation area; the support ( 20 A) having cuts ( 31 A) that, upon application of a load equal to or exceeding a set value, fracture and function as a release portion to thereby release the support from being held in a vertical position in the installation area; and the support ( 20 A) being plastically deformable by a load less than the set value.
