Try your local council. Mine is very helpful, I get people parking over my dropped kerb drive very often. The local council will come and fine them £60 and even pick the car up and take it to the local pound. Costs the driver about £200 to get it back. Do not see why it would not work with commercial vehicles.
There are 10 types of people: those who understand binary and those who don't
this should work with every vehicles report it to your local council about a vehicle blocking your drive and can't get out if you work overnight or report the vehicle to the cops about a blocked drive way cops have more power to move the vehicles.
