Abstract

Consistent and reliable releasing of a guardrail during a vehicle impact is enabled by a releasable fastener for safety structures along a highway. The release of secured components such as guardrail is controlled, and precise positional cooperation is provided between securing members and the guardrail.
Forces may be attenuated to further optimize response.
