The distribution of lorries around the world varies depending on factors such as economic activity, infrastructure, and regulations. Some countries, particularly those with large manufacturing, agricultural, and construction sectors, tend to have a higher number of lorries. Developing countries, on the other hand, may have a smaller truck population due to limited infrastructure, lower levels of industrialisation, and a greater reliance on other modes of transportation.
Additionally, the number of lorries in a country can be affected by regulations on vehicle emissions and fuel efficiency. Stricter regulations may lead to the replacement of older, less efficient trucks with newer, more environmentally friendly models, resulting in a change in the overall lorry population.
It's important to note that these numbers are estimates and may differ depending on the source and the criteria used for counting lorries.
