Bank, that law already exists under the Highways Act.

The provision is for 42 inches (old law, old measurements).

Find someone to enforce it though!

It is the same with over 95% of our laws.  They exist and are fully enforceable but we no longer have enough enforcement personnel (Police?) to do the job.

Take the use of mobile phones while driving - one camera on top of a bridge over a busy road would result in enough summonses in an hour to bring the local Magistrates system to gridlock.

Maybe that is why we no longer have enforcement.  Not enough people to prosecute and not enough facilities to enforce.

When people are routinely caught and prosecuted, successfully, for an offence it is a known fact that incidents of that offence are dramatically reduced.

We need someone to show some backbone, sack the PC brigade and give us our country back.

I can dream.................
