ask hertz for proof you want a picture of yourself driving that car a the moment of the offence. as it was a hire car anyone could be driving it at the time.also i would try and get a 1/2hr free consultation with a solicitor just in case.how many points do you have on your licence?.if you have 3 or more and get 3 more for each offence you will have to go to court if they count from holland!.
