Why doesn't Hong Kong switch to right-hand traffic?

[StephanieLynn]

Hong Kong's urban roads are narrow, with many being one-way lanes. If the traffic direction were to be changed, a large amount of infrastructure would need to be modified, which would indeed be quite challenging. Here is relevant information about Hong Kong's left-hand traffic: 1. Historical reasons: Since Hong Kong was a British colony from 1842 to 1997, and vehicles in Britain also drive on the left, Hong Kong adopted left-hand traffic rules. 2. Traffic rules: After Hong Kong's return in 1997, the mainland and Hong Kong adopted a "one country, two systems" approach to road traffic issues. Mainland vehicles entering Hong Kong must follow Hong Kong's left-hand traffic rules. Conversely, Hong Kong vehicles entering the mainland must also follow local customs.
