In British English you might use 'of' for a specific thing, eg. a book or person, and 'on' for a broad topic, eg. 'your opinion on string theory'.

But it's not a very strong rule, I wouldn't feel that either was wrong. This may be the effect of American English usage of 'on'.

To your specific question,

We surveyed drivers' opinion on this device?

of might be less ambiguous about whether you were talking about their opinion of the device, or you used the device for the survey. Does "We surveyed drivers opinions on twitter" mean you asked them about twitter or you used twitter to ask about something else?

  • Thanks @mgb. I understand... I should say We surveyed drivers' opinion of this device?

  • For example: I do not give my private opinion of my nearest relations.

    @Stat-R: You've got mgb's distinction right, in that this device is a specific thing, so opinions would normally be of it. But it should always be drivers' opinions in the plural for your construction. Mar 29, 2012 at 16:28

    I don't there there's any difference between British and American usage here. Mar 29, 2012 at 18:24

Exactly, when it is a broad topic, we can use 'on', but when it is a matter of 'good,or 'bad' we can use of. For example, "Your opinion of me does not define who I am". Another example can be, what is your opinion on politics.
