A properly designed roll cage can significantly enhance occupant survivability and reduce injuries in a competition vehicle which may find itself in a rollover situation either at the race track or on the open road.

The roll cage can also assist in reducing injury from front, rear and side impact events particularly where glancing collisions are sustained.

Aside from roll over protection, a properly designed roll cage can also provide substantial mountings for safety harnesses and seats which are better able to withstand the very high G loadings experienced in a collision.
