Here are some specific examples of how UK motorways are used at night:
* The M1 motorway is one of the busiest motorways in the UK, and it is even busier at night than it is during the day. This is because the M1 connects London to many major cities in the north of England, and many people use this motorway to travel for business or leisure at night.
* The M6 motorway is another busy motorway that is even busier at night than it is during the day. This is because the M6 connects Birmingham to Manchester, and many people use this motorway to travel between these two cities for work or shopping at night.
* The M25 motorway is a busy motorway that surrounds London. It is used by many people to travel into and out of London at night, especially for work or to go to events.
In addition to these specific examples, many other UK motorways are used at night for a variety of purposes. This includes people traveling for business, leisure, or to go to work. Additionally, many businesses use the motorways to transport goods at night.
