Unfortunately the courts are being a lot stricter on these sort of things now.
I was charged with doing 110mph
I got 28 days ban ( only 1 week and 1 day left!!! ) and £510 fine.
Personally, i wouldnt waste your time with exspensive soliciotrs, just plead guilty but include a letter of mitigation.
Plead, plead, plead and plead, saying you will lose your job if you lose your licence, which in turn will affect your children/wife/pet dog/ mother etc etc and say you are genuinely remorseful and it will never ever happen again. Also state in the letter you have had a clean licence for how ever many years you have been driving!
If you can get a supporting letter from your employer, this WILL DEFINTELY help!
If you need any help just pm me
