What is side road? How to use in English

The term "side road" has its origins in the English language, specifically in the United Kingdom. It was coined during the 19th century, as the country's transportation infrastructure began to expand rapidly. Previously, roads in the UK were largely unregulated and unstandardized. There was no clear distinction between major thoroughfares and lesser-used routes. This led to confusion and complications for travelers, as there was no easy way to distinguish between the two. To remedy this, authorities in the UK began to standardize road signs and classifications. In 1835, a series of road naming conventions was introduced, which included the term "side road." A side road, in this context, was defined as a road that connects a main road to a smaller or lesser-used network of streets. This term was intended to help travelers better understand the road system and to make navigation easier and more straightforward. Over time, the term "side road" has become widely adopted not just in the UK, but in other English-speaking countries as well. Today, it is a common and accepted part of the language, used to describe a variety of different road types and situations.
