I agree this is strange and sounds like the scheme is designed to avoid police work that could involve anyone being charged with an offence. It would make more sense as “Vehicles cannot be stopped unless a police officer is present at the scene”.
Is a scheme like this a better use of time than simply reporting offences to the police, and the police investigating and issuing charges.
