Why put a TACCA sign on, it means nothing to people.
Especially when you have to pay for it.
Same as putting NCCA or IIRC or whatever, means
nothing to people.
Put something on your van that people can relate to
like a business card holder, so when your parked in
supermarket people see your sign and grab a card.
Best £15 I ever spent, it's there for passing pedestrians
when your parked at a job too.
