The M42 motorway is a major road in England. The motorway is 55 miles in length and spans Bromsgrove in Worcestershire to Ashby-de-la-Zouch in Leicestershire.
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.
The M5 motorway in England is approximately 163 miles long, stretching from Birmingham to Exeter.
