Section 59 and a fixed penalty notice

Hearsay is an evidential procedural issue, and it doesn’t apply to police officers receiving information about offences, it would still require the original police officer who saw the offence to give a statement, but that is easily done. There are also exceptions to the rule which might apply here, such as giving the evidence to a person in authority who immediately writes it down.

As to the FPN could call these people: http://www.pattersonlaw.co.uk/

I don’t know them, but they offer free advice as a starting point.

Offence code 124 is used for things such as reading a newspaper/item/text changing the filter in a coffee machine in a 44 ton HGV (I kid you not) whilst driving. The list is endless
but this is to give you an idea. Here it could be said that since your front wheel was not in contact with the road. Therefore should an emergency situation develop in front of you, you would not be able to react to it. This is only an overview and not a look at your driving skills etc, even if you were Dougie Lampkin!
