Free Traffic Legal Advice

Realistically, can a layperson become proficient in fighting PCNs and helping others to fight theirs without undertaking any sort of formal study of law?

I was reading Hippocrates' thread from a few years ago about how to encourage more people to fight their PCNs, and there was also some discussion about the amount of appellants against willing representatives and resourcing and logistics, etc.

I understand that this would naturally take time and a lot of experience. I'm not sure to what extent the regulars on here have undertaken a formal study of law, and if they currently practice law, or are perhaps students?

I ask in what ways could I start to be able to fight PCNs all the way to adjudication. I do often simply read cases on here and on the appeals register, but I don't think that will do much in the way of applicable knowledge.

So I guess it's just a process you have to go through and as you start fighting more you get to grips with procedures, processes, legislation, what actually may render a PCN invalid in accordance with the law, etc.

I know someone who's been fighting all his PCNs since forever, and it does seem to be an experience thing. I guess what I'm wondering is how can one be more intentional about it rather than just letting experience alone take them through it, which would also mean relying on getting PCNs.
