mounting danger

I'm a little stuck... Click here to teach me more about this clue!

'jockeys?' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'increasing hazard' is the wordplay.
'increasing' becomes 'mounting' (mounting is a kind of increasing).
'hazard' becomes 'danger' (a hazard is something dangerous).
'mounting'+'danger'='MOUNTING DANGER'

'for' acts as a link.
