OUTLINE

This mod applies real statutory speed limits to the vanilla map.

Sources of my data are the rules, codes and announcements made by local authorities.

Be cautious of other speed limit mods that claim to be realistic but provide no actual sources.
I've made a comparison table with sources listed to show that I do my studies carefully.

This project is a continuation of the same mods I created for ETS2.

As I need to edit some speed limit signs (which is not permitted by SCS on the Steam Workshop due to map modifications), the ATS version is only exclusively available on TruckyMods.
