Which version is better?:
- The permit should be placed behind the windshield of a vehicle and produced at the request of authorised persons.
- The permit should be placed behind the windshield of a vehicle and produced on demand from authorised persons.
Can the past participle "produced" be used in place of the past participle "shown"?
Yes, produced is okay. It implies "shown", as there would be little point in producing a permit without showing it to the person who requested it.
I'd write produced when requested by authorized persons. Note that I've used the AmE spelling of authorized and that the BrE word for the big sheet of laminated safety glass in front of the driver is, I believe, windscreen.
