1. A crash cushion comprising:
a first rail section comprising an upstream end portion, a downstream end portion and a first side;
a second rail section comprising an upstream end portion, a downstream end portion and a second side facing the first side of the first rail section, wherein the upstream end portion of the second rail section overlaps with and is secured to the downstream end portion of the first rail section with a fastener, and wherein the first rail section is moveable relative to the second rail section from a pre-impact position to an impact position in response to an axial impact to the crash cushion;
wherein the first rail section comprises a plurality of longitudinally spaced slots aligned with and extending upstream of the fastener, wherein the plurality of slots comprises a first elongated slot aligned with the fastener when the first rail section is in the pre-impact position, wherein the first elongated slot has a first length; and
a support post releasably connected to the first rail section and rotatable from an upright position to a laid over position, wherein the support post is releasable from the first rail section and is rotatable to the laid over position after the first rail section has moved a first travel distance during the axial impact, wherein the first length is greater than or equal to at least 75% of the first travel distance.
