Surely the police can't issue a penalty notice which doesn't state what offence has allegedly been committed.That being so, the person named can find the Act, the section of it and any Regulation which creates the offence.When there was a rumour of such an offence last year I did hunt through Wilkinson's Road Traffic, Stone's Justices Manual and other books and could find no such specific offence of failing to secure a dog .There may be one now, but from what the police at the various police stations said [above], it looks as though the offence was one of failing to keep proper control of a vehicle. That must be question of fact and degree. Hence the question of the officer's opinion, for one might view the same evidence differently from another.Plainly allowing dogs to bounce about in a car might affect the driving and control of the vehicle but dogs which are seated and have shown no such tendency hardly do .Perhaps someone in authority has told the press that unsecured dogs are an example of the kind of thing which might result in this offence being committed,but just as an example, not a rule in itself.
