Abstract
An intermediate transition for connecting a crash cushion to a rigid structure includes a housing and an energy absorbing module. The housing defines an inner space and includes a top wall, a front wall, a rear wall, and a side wall. The front wall is operatively associated with the top wall and is operable to connect to the crash cushion. The rear wall is operatively associated with the top wall and is operable to connect to the rigid structure. The side wall is operatively associated with the top wall and includes a weakened portion. The energy absorbing module is located in the inner space of the housing.

An intermediate transition for connecting a crash cushion to a rigid structure, the intermediate transition comprising:
- a housing defining an inner space and comprising:
- a top wall;
- a front wall operatively associated with the top wall and operable to connect to the crash cushion;
- a rear wall operatively associated with the top wall and operable to connect to the rigid structure;
- and
- one or more side wall operatively associated with the top wall and including one or more weakened portion;
- and
- one or more energy absorbing module located in the inner space.
A crash cushion system for connecting to a rigid structure and absorbing energy when impacted by a vehicle, the crash cushion system comprising:
- a plurality of energy absorbing cushions;
- and
- an intermediate transition attached to the plurality of energy absorbing cushions and operable to connect to the rigid structure, the intermediate transition comprising:
- a housing defining an inner space and comprising:
- a top wall;
- a front wall operatively associated with the top wall and operable to connect to the plurality of energy absorbing crash cushions;
- a rear wall operatively associated with the top wall and operable to connect to the rigid structure;
- and
- one or more side wall operatively associated with the top wall and including one or more weakened portion;
- and
- one or more energy absorbing module located in the inner space.
