Roads are a little complicated., roads were built to be LHT. After being independent, they decided to changed to have traffic rules to RHT. But roads were designed to be LHT hence certain junctions, slip roads and T-junctions are still confusing. Highway codes are still LHT rules and sometimes you get dangerous and weird signals from other drivers or other road users. e.g.. slower vehicles are keeping left rather then right. Bicycles and push carts use the centre of the roads.
