Crazy family likely to cause an accident (6,4)
I believe the answer is:
banana skin
'cause an accident' is the definition.
'banana skin' can be an answer for 'cause' (I have seen 'cause of embarrassment' mean 'banana skin' so perhaps 'cause' could also mean 'banana skin'). I am not certain of the 'an accident' bit.
'crazy family likely' is the wordplay.
I cannot really see how this works, but
'family' could be 'banana' (banana family is a kind of family) and 'banana' is found within the answer.
The remaining letters 'skin' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for banana skin that I've seen before include "Potential for accident, embarrassment" , "Potential disaster" , "Something unforeseen that may cause a slip-up" , "potential hazard" , "A disaster waiting to happen" .)
