I believe that the highest numbered motorway in the UK is the M898 a short 1/2 mile spur off the M8 in the Glasgow area.
The highest motorway in the UK is the M62 near the boundry between Yorkshire and Lancashire which reaches 372 metres (above ordnance datum)at it's peak. == ==
The first Motorway in UK (M6) was opened in 1958.

A motorway in the UK is a major 'divided highway' type of road, serving major towns and cities. A motorway 'marker' could be the small signs seen along a motorway that identify the exact location and distance to the end of the motorway (useful for reporting position if your car breaks down). These are every 500 metres. If the question is about how motorways are marked in the UK, then all motorway signs are white text on a blue background. Exits (off-ramps) are signposted well in advance while driving on the motorway.
There is no motorway from Glasgow to Aberdeen
No. Motorways have M numbers, not A numbers.
Yes, a Robin Reliant is not classed as a 'slow vehicle' for the purposes of exeptions to the motorway.

The first motorway opened in Britain was the M6 (M=Motorway). It was known as the Preston Bypass. It was opened in 1958. When it was planned, the Preston Bypass was seen as the first piece of a large network. It was deemed a success and led to the construction of a second motorway, the M1, opened in 1959. There was no speed limit and no crash barriers and hardly any traffic -- now that's what I call motoring! The M6 is also Britain's longest motorway and Britain's busiest.
