Might Have Been Caught Speeding - Help

[RSWelsh21]

Hi All

I'm after some advise please, not any lectures.

I was coming home from work today driving on the motorway, some idiot cut me up so I missed my turn off and had to take the next exit. In anger and a rush I put my foot down. I was doing around 120/130mph and seen a speed camera van on the overhead bridge. I obviously slowed down as soon as it came into sight.

What sort of punishment am I looking at for this?

Thanks In Avdanve
James
