1. Bangladesh

Bangladesh lies in South Asia, bordered mainly by India, with Myanmar to the southeast and the Bay of Bengal to the south. Traffic drives on the left. Much of the country is low-lying and crossed by major rivers including the Padma, Jamuna and Meghna, so bridges, floodplains and river crossings are an important part of road travel. The summer monsoon can bring prolonged heavy rain and flooding, while urban driving—particularly around Dhaka and Chattogram—often involves dense mixed traffic. Bangla is the national language, but official route signs display destinations in both Bangla and English, normally with Bangla above the English name.

Bangladesh does not use a nationwide motorway vignette; instead, tolls apply to individual bridges, expressways, tunnels and other designated infrastructure. Speed limits are unusually dependent on both road class and vehicle type. Under the national 2024 speed guideline, ordinary cars and buses may travel at up to 80 km/h on expressways, while motorcycles and freight vehicles have lower limits. Three-wheelers are prohibited on expressways and national or regional highways. During the monsoon, flooding and waterlogged roads can significantly affect travel, making temporary restrictions and local traffic directions especially important.
