Caught speeding - advice

[Matt 211988]

I've just returned home to find a notice of intended prosecution.
77mph in a 50mph (single carriageway)

can anyone advise on what the penalty is likely to be? (I already have 3 points for 86mph in a 70)

Do I fill the form in and just wait to see what is said or do i need to ask for evidence etc first? obviously I want to find out it was definately me first, or do i complete the form and ask for the evidence at the same time?

any other advise from legal folks on how I should proceed?

thanks
matt

thanks agtlaw.

any chance you can explain the band a fine, band b fine, starting point and range to me?
i guess band A is £60 fine and 3 points, band B £100 fine and 6 points?

If i am summoned to court, is it a fixed date I have to attend? (i work away and I can guarentee it would be during my time away )

you say that asking for the evidence doesnt postpone the time i have to respond to the notice, am i best off just sending the form back along with a request for evidence?

i've had my licence for, 7 years i think
