What is the speed limit for vehicles passing through villages and towns on national highways?

[StKevin]

Normally, the speed limit on provincial and national highways is 80 km/h, but when passing through villages, towns, residential areas, or near schools, the speed limit is reduced to 60 km/h or 20 km/h. Speed limit regulations: Motor vehicles driving on the road must not exceed the maximum speed indicated by speed limit signs. On roads without speed limit signs, drivers should maintain a safe speed. National highways: These refer to major trunk roads with national political and economic significance, including important international highways, defense highways, roads connecting the capital with provincial, autonomous region, and municipal government seats, and roads linking major economic centers, port and station hubs, commodity production bases, and strategic locations. Cross-provincial expressways within the national highway system are constructed, maintained, and managed by specialized agencies approved by the Ministry of Transport.
