I AGREE with D Edge's letter (September 29). I presume that by "scooters" he means the 4-wheeled mobility buggies, sales of which have boomed in the last couple of years.

There is hardly a day in the city centre when I do not encounter one of these being ridden on the road. The law is not yet clear on the legality though.

Let me say that these buggies are a boon to many people, and I am generally in favour of them, so please don't be offended, users! I was invalided in an accident last spring, and a crank-driven recumbent trike was both a godsend to me and a bane to shopkeepers.

If the buggy is a mobility aid, and the rider can show this, then it should be treated just like a pedestrian, and allowed anywhere.

Often the buggies are on the road due to narrow or obstructed footpaths, and it is the duty of each driver to take care, just as it is with any vulnerable road user.

The police can take action if the buggy is being used carelessly or is causing an obstruction.

If the buggy is not being used as a mobility aid, then it is a motorised vehicle and is not allowed on any path or highway.

This rule also applies to those pesky electric mini-scooters, petrol "Go-Ped" type scooters and even some electric bicycles.

At least two leading brands of electric bicycles are not legal on the pavement or highway.

To be legal, the motor must be linked to the pedals so it only cuts in when you pedal - "electric assist", rather than "electric propelled".

If your electric bike will drive itself along without pedalling, then you need a registration plate, insurance, a tax disc and a proper helmet.
