What is a locomotive which apparently is some kind of vehicle with a max width of 2.75m and tows trailers. I’ve googled and I keep getting pics of trains. Anybody can help?
Ooooh, it’s years since I did my CPC! Sorry, I can’t remember the definition but is there also a “heavy motor car” in there too?
Try googling ballast tractor, I think that’s something close.

The term has been in use since the dawn of motor vehicles in late 19th century.
A locomotive.
As mentioned it’s a vehicle that’s used purely to move the likes of heavy haulage or another example would be a tractor unit with an engine on the back or generator as in fairground vehicles .
Basically it is a tractor unit which is used for towing trailers, as opposed to semi-trailers (i.e. wheels at one end and landing legs at the other) which is what the vast majority of us actually mean when we refer to our “trailers”.

This was the term originally used for steam traction engines in the 19th Century. If you Google “Road locomotive” you will see examples, lots of these at steam rallies in the summer.
locomotive=( in todays terms as far as heavy haulage goes) the load is pulled by the tractor, and not carried, unlike a tractor unit where some of the load is imposed on the unit- That clear? thought not 
a locomotive does not have a fifth wheel, it instead tows the load normally via a bar , although a tow dolly axle has been used, the load is totally supported on the trailer, where as a tractor unit has a Fifth wheel and some of the load weight is transferred to the unit
clear as mud eh ?
the laws around locomotives are really complicated - but suffice it to say if you jump through all the hoops. you can, using a 4x2 ballasted tractor unit,on an A frame towing a dolly with a fifth wheel, hitched up to to a 20 foot skelly trailer pull a 20 foot container loaded to 40 tonnes - ask any one on Teesside TDG ran them quite legally for many years- the 20 MPH max speed was a bit of a drawback but they was only running Wilton to Teesdock ( 2-3 mile)
Had that on my first licence ( the little red book )
Heavy locomotive ( over 21 y o )
Light locomotive, under 2 tonnes?
